Title: jpne: Japan Expressways
Post by: yakra on April 24, 2019, 11:36:50 pm
E6: 9-1(Job)-> 9 (https://www.google.com/maps/@36.3807175,140.3859101,3a,15y,5.57h,94.05t/data=!3m6!1e1!3m4!1swHbRbECNlunBXF51L3Lm9A!2e0!7i13312!8i6656)(Job) / X659146 -> 9-1 (https://www.google.com/maps/@36.4142048,140.4214827,3a,75y,55.34h,104.54t/data=!3m9!1e1!3m7!1s1Db4ZA8VqNYHsa_KzIgDYA!2e0!7i13312!8i6656!9m2!1b1!2i41)(Job)
E9: Not sure if the E88 concurrency is a thing. Kyoto Tramway Expressway (https://ja.wikipedia.org/wiki/%E4%BA%AC%E9%83%BD%E7%B8%A6%E8%B2%AB%E8%87%AA%E5%8B%95%E8%BB%8A%E9%81%93) / Gyeonggi bypass (https://ja.wikipedia.org/wiki/%E4%BA%AC%E6%BB%8B%E3%83%90%E3%82%A4%E3%83%91%E3%82%B9) / But then again...

I'll do the review once the English routes of gbnb will be done.

Since no specific source (http://travelmapping.net/credits.php#regionsources) is indicated I assume that wikipedia (https://en.wikipedia.org/wiki/Expressways_of_Japan) is the source.
The box at bottom does not indicate E16, E31, E82, E83, E84, E85, E88, E89, E90, E91, E92, E93, E94, E96 and E98. The article seems to be outdated  :(
The urban expressways from wikipedia are not in HB (I didn't check all).

First look what is missing in HB:
- There is a E1A north of Osaka from E2/E2A junction to the east.
- Just south of it is a route indicated being "7".

Both are indicated on OSM and GM with green shields like the other routes.

"7" has a different shield (https://www.google.com/maps/@34.8351412,135.2661034,3a,38.8y,253.62h,102.93t/data=!3m6!1e1!3m4!1sYDVape6z_vJ0WGu0m4XXEw!2e0!7i13312!8i6656) on GM and GSV.
Another example (https://www.google.com/maps/@34.6808424,135.017867,3a,48.9y,28.51h,115.52t/data=!3m9!1e1!3m7!1sBkuDV19IB5q45zWEifzohg!2e0!7i16384!8i8192!9m2!1b1!2i36) that the rectangle green signs seem to be the criteria.
Also here (https://www.google.com/maps/@35.8433362,139.8513582,3a,34.3y,121.97h,115.42t/data=!3m9!1e1!3m7!1sAIF-w5b6Hd-ygMU48400mw!2e0!7i16384!8i8192!9m2!1b1!2i36).
However, the E1A missing in HB has the correct(?) rectangle shield (https://www.google.com/maps/@34.8441896,135.2260118,3a,16.4y,338.27h,105.95t/data=!3m9!1e1!3m7!1spyJui4oQ4MsFNWHvMaMAYQ!2e0!7i13312!8i6656!9m2!1b1!2i36).

The national highways (https://en.wikipedia.org/wiki/List_of_national_highways_of_Japan) have a blue shield.

The expressways around Osaka like "7" with the other green shield seem to belong to Hanshin expressways (https://en.wikipedia.org/wiki/Hanshin_Expressway) - one of the "urban expressways (https://en.wikipedia.org/wiki/Urban_Expressways_(Japan))" (which are networks).

=====================

Is E1A missing on purpose?
Is the rectangle shield the criteria for routes to be included?
What's the exact reason that we exclude the other expressways indicated with the different green shield? Should we rename the system to "Japan National Expressways" (and add the additional urban expressway systems for the other networks anywhere down the road)?

Is E1A missing on purpose?
Of course not. You'll note that there isn't a junction at the E1 - there would be if it was deliberate. When I drafted the system it wasn't open. When I went back to look for routes, it got buried in the all urban expressways and mapped-as-expressways-but-aren't-formally-such around it.

Not really. It was more that the shield rather than a prefix excluded the urban ones.

Because they are not part of this system, but their own ones. We'll call the system a latinised version of the Japanese.

OK. Should I wait till you've added E1A (and maybe other missing routes - It took me less than 60 seconds to find this and I didn't checked other locations) or should I already start the review?
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 09, 2021, 08:58:19 am
I would like to volunteer to peer-review jpne.  michih suggested that I volunteer for this as he will not be able to get to it for some time. 

I have read the developer's guide and looked at some jpne entries to get a feel for Japanese expressway routing.  I can read Japanese, so I will be able to access source materials if there are any available.

There aren't any Japan entries in credits.php, so I took a short look at the ministry website.  I can find lists of roads and GIS maps that seem up to date, but so far no detailed explanations of routing.  Also found: bureaucratic Japanese is awkward and hard to decipher - my formal language skills need work.

Do you have a link to the GIS maps?
Title: Re: jpne: Japan Expressways

I just used the general sources like wikipedia and mapping for creating this system.

I was looking at the disaster information map on the ministry website.

https://dimaps.mlit.go.jp/dimaps/4/WebContent/html/map/main/mainMap.html?&t=0-1-0&ll=37.57152159224726,140.6538391113281&z=11

The manual is here:
https://dimaps.mlit.go.jp/dimaps/index.html

If you click on the first button in the upper left corner, a popup of options appears. The fourth folder down is roads. Open it and the second option is highways. I haven't explored much further than this.

I think this is the base for DIMAPS.
https://www.gsi.go.jp

I checked the GSI map for the sections of E55 in Tokushima and E45 in Iwate which opened a few weeks ago.  They are present on the GSI map.

http://altcva.main.jp/pref/

This is a non-official route viewer for Japanese expressways, national roads, and prefectural roads. You choose what to look at using the panel in the upper left corner. The first two choices are expressways and national roads. The other entries are the prefectures, listed north to south. Click on a prefecture to see a list of its prefectural roads.  The selector panel says that all route map data is from OpenStreetMap.

Post by: nezinscot on April 11, 2021, 03:30:23 pm
I reviewed the C routes in Tokyo.

CA, C3, and C4 cross prefectural borders. Should there be points at the borders?


CA:

a) The Umi point is just a parking area that allows U-turns. Should all u-turn-only exits be included? There is an unmarked similar exit on C4.

C3:

a) C3 extends to E51. Exits 85, 86, 90(E14), 91 and 92(E51) need to be added.
b) The point for exit 83 is north of the actual exit.
c) E14 needs to add exit 1-1 for C3.
d) E51 exit 1 intersects C3.
e) SEB exit E51 intersects C3.

C4:
a) Exit 32-1 is a parking area that allows u-turns. Should it be included?
b) Is N# how national highways should be referenced?
c) Did you use E1A, E1 and E20 as names because their numbers (1, 4-1, 6) did not match the normal exit number sequence?

C4Mob:
a) Need to add exits 101-1 and 102-1. They are new SICs.
b) Exit 92 is not labeled 92 on road signs. It is marked as shuuten, which just means "end point".

According to which rule?
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 11, 2021, 06:39:31 pm
I apologize for being unclear about why I asked this question.  I don't know the future plans for Japan - divided or undivided.  If Japan is an undivided country I don't need to worry about  prefectural boundaries.

The other questions are for me to know more about what exits should be included and how expressway waypoints are named.

I would like to add them, though there's no should about doing so.

It's how I have referenced them - it seemed logical with the E for Expressways. Have you another suggestion?

Quote

Yes. Thoughts from the floor on this.

Alternatively I could call them 1(E1A), 4-1(E1) and 6(E20) - as numbered exits from another route's exit numbering system, but that strikes me as rather pointless.

I found it clear. No plans to split Japan at this time. We'll cross that bridge if we come to it.
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 12, 2021, 12:23:24 pm
Thanks for the clarifications.

I decided to work my way north - Kyushu to Hokkaido.  I thought things would be simpler down south. They aren't.  Here are a few updates for some of the shorter Kyushu expressways.

E77Kum
a) has new exits IC2 and IC3

E77Tak - new road
a) There is an additional section of E77 open. It is a tunnel between N218 in Takachiho and a farm road that leads to N218. I suggest using Tak(achino) as the name -  it's a popular tourist site.

E96
a) E96 branches just before exit 11-3. Branch A goes to P113. Branch B goes to P235 and is part of the current entry for E96.  A new entry for Branch A is needed.
b) I would use E34 instead of 11 as the first exit name.  11 is the exit number on E34 for getting on E96.

E97
a) You might be able to use the IC numbers instead of route numbers:  N10(1), ToN213(Jct2), P4(3).  E97 is made up of three pre-existing roads. I don't know if the numbers being sequential is a fortuitous accident, or not.
b) Exit IC4 does not have a waypoint. It goes to P404.

E98
a) E98 starts at IC5, not IC4-1. The highway between IC4-1 and IC5 appears to be a branch of E10.  It is definitely a part of the Miyazaki Expressway.  I used GSV to look for E10/E98 signage, but didn't find any in the 2017-18 street views.  The Japanese wikipedia page for the Miyazaki IC (5) says that it is on E10 and that E98 is a connecting road.
b) We probably need a new entry for the E10? branch between IC4-1 and IC5.
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 12, 2021, 05:00:21 pm
More Kyushu.

E3AYat
a) The existing exit numbers should be 1 thru 5 (1-1 became 2).
b) The road has been extended and now ends at IC6.

E3AIzu
a) The road now starts at IC9.

E3
a) There are four new ICs to add:  4-2, 14-1, 19-1, and 25-2.

Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 13, 2021, 12:33:49 pm
The rest of Kyushu, plus Okinawa

E10
a) Exits 10(Hig) thru 13(Hig) are actually numbered 9-1 thru 9-4 (verified with GSV). Because of this there is probably no need to use the (Hig) and (Oita) indicators in the exit names.
b) Need to add exits 10-1, 24-1, 28-1.
c) Need to add exit 3-1(Miy).

E34
a) Consider using E10 as the exit name instead of 10(Oita)
b) Add new exit 9-1(Oita)
c) Add new exits 3-1(Nag) and 9-1(Nag)
d) The 1(Nag) exit was confusing when I looked at it on GSV. I can see why you used 1 and 1a. You could alternatively use N3 and N34 which is what the signs on E34 use.

E35
b) The exits are listed low to high. Should they be flipped? The E35 Japanese wikipedia page lists exits starting in Fukuoka and ending at E34. E35Fuk, E35Mat, and E35Kar use the order wikipedia uses.

E35Fuk
a) Consider using FEC as the exit name instead of Fuk
b) The road ends at P573, not P12.  Move the P12 point to P573 and rename it.  Or name it N202 because that is the continuing road.
c) The other exits all connect to N202 which follows underneath the expressway, but the town names are less confusing that using N202A thru N202D, plus they mirror the exit signs on the expressway.  I would also use Ima(juku) instead of P561; P561 is not listed on the exit sign.

E35Kar
a) Consider using the IC numbers (24 thru 18) instead of road names.

E35Mat
a) Consider using the IC numbers (14 thru 11) instead of road names.

E58 (Okinawa)
a) Need to add exit 3-1
b) At exit 1-1, there is a long exit west to P82. I could not find any indication on the web that this long exit is considered a separate branch of E58, so what exists now is probably OK.

E78
a) Consider using E3 as the exit name instead of 25-1 which is the E3 exit number for E78

E78Miy
a) Consider using E10 as the exit name instead of 4-1 which is the E10 exit number for E78Miy

Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 14, 2021, 10:27:46 am
Hokkaido expressways

E5
a) The exit numbering is now sequential S to N, from 6 to 48.  20(S) is 6, 13(N) is 48, 1 is 32.
b) Need to add exit 21 - between 7(S) and 6(S)
c) Need to add exit 27 - between 4(S) and 3(S)
d) Need to add exit 31 - between 2(S) and 1
e) Need to add exit 33 - 0.5 km east of the E5, E5A junction. The exit is almost part of the junction. Coming from the north on E5, exit 33 goes straight to N274, while bearing left is exit 32 which continues E5.  Only the latest GSV shows the new exit numbers.
f) Need to add exit 40 - between 7(N) and 8(N)

E5Toy
a) The Japanese wikipedia page for the road says that as of 2020 the exit numbers are no longer used. OpenStreetMaps uses IC names without numbers. But GSV from 2018 shows all four exit numbers in use. If you decide to follow OSM and wikipedia, these names could be used for the exits
1: P121
2: P84
3: P923
4: N40

E5A
a) Use E5 instead of 1-1.
b) Exit 4 is missing. The waypoint for exit 3 is located between 3 and 4. Add 4 and move 3 east of P231.  3 (exit westbound) and 4 (exit eastbound) are a pair, but they are numbered separately.
c) The waypoints for 1 and 2 are not positioned at the exits. 2 is too far NW and 1 is too far SE. (Exits 1 and 2 are similar to 3 and 4.)

E5AKur
a) The Japanese wikipedia page for the road says that as of 2020 the exit numbers are no longer used. OpenStreetMaps uses IC names without numbers. GSV from 2018 shows the exit numbers in use.  If you decide to follow OSM and wikipedia, these names could be used for the exits
1: P344
2: N5

E38Kus
1) The road ends at exit 20, which could be named E44 because E44 begins at that point.

E44
a) This road needs to be added. It begins at exit 20 at the end of E38Kus. It has two exits - E38 (20) and 21.

E44Nem (for Nemuro, at the eastern tip of Hokkaido)
a) This road needs to be added. It has two exits - N44_S and N44_N.

E59
a) Exit 1 could be called E5.

Shikoku - Honshu connector expressways

E2Kim - new route
a) E28 does not extend to E2. A short branch of E2 heads south to connect to E28.
b) There are two waypoints - E2 (IC2 on E2) and E28 (IC1)
c) Kim is from the road name - Kimi Branch Line

E28
a) E28 does not extend to E2. It starts at IC1, which could be named E2Kim
b) New exit 7-1 needs to be added.
c) New exit 4-1 is part of the exit 4 complex at the Awaji Highway Oasis. 4-1 allows entry from P157 to the service area. Its location is WNW of the electric vehicle charging station at the north end of the Oasis parking lot.

E2Kur - new route
a) E30 does not extend to E2. A short branch of E2 heads south to connect to E30.
b) There are two waypoints - E2 (IC16 on E2) and E30 (IC1)
c) Kur is from the road name - Kurashiki Hayashima branch line

E30
a) E30 does not extend to E2. It starts at IC1, which could be named E2Kur
b) Exits 3-1, 3-2, and 3-3 only allow entry to local residents and delivery vehicles (and the GSV vehicle). The toll booths at the exits require a separate payment card for islanders only.

very clearly signed as E28 For Akashi Bridge (https://www.google.com/maps/@34.8078752,135.0717528,3a,27y,30.45h,92.26t/data=!3m6!1e1!3m4!1stiegrGkzxP4fnGfMObN8aw!2e0!7i13312!8i6656) at E2. Might be able to justify it being an E2 spur, counting that as a 'to' rather than the E2 signage at the other end, but that name doesn't appear at either end.

Same goes for all these spurs. It's a bit like Italy, but without the big chainage/confirmatory markers (https://www.google.com/maps/@45.0814512,7.5433437,3a,34.7y,314.01h,91.38t/data=!3m6!1e1!3m4!1s4-v3A1d_bSodJFuXaXQOoQ!2e0!7i16384!8i8192) that justify the silly spurs (https://travelmapping.net/hb/showroute.php?units=miles&u=si404&r=ita.a055riv) that would more logically be the mainline of another route of the same system being included as signed.

I've done pretty much everything else, but I've not done the un-/not-really signed spurs. I might do them, but at the moment, I'm undecided.
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 15, 2021, 09:55:11 am
I think the spurs are a result of the E highways largely being formed by combining pre-existing toll roads. The spurs and the main line are separate toll roads.  If you think the spurs are unnecessary, I don't disagree.  No one would be taking them unless they were using the other highway.

The 2016 government document defining the E roads only lists the pre-existing roads that will make up the highways. Start and end points are not listed, but I can usually figure them out from looking at the individual toll roads. It gets complicated because one toll road may be part of multiple E roads, or only partially part of one.

I've finally figured out that the "most likely correct" info on the E routes is to check the Japanese wikipedia pages for the individual junctions.  Each has a section called 隣 "Next to" which lists the roads leading into and out of the junction.  The constituent toll roads of the E highways have detailed wikipedia pages, including all the junctions and interchanges. (The english equivalent pages are almost always out-of-date.)  I'll look at the junctions for E28 and E30 again and see if I can find out more.

Japan's longest expressway

E4
a) Add exits 7-1, 10-1, 11-1, 15-1, 17-1, 31-1, 35-1, 40-1, and 42-1.
b) Waypoint 1 could be called S1/C3 or C3/S1.  S1 is the continuing road.
c) Waypoint 2 should be moved further south, to where the ramp toll-booths are. This is just NW of the southern IC2 label on OSM.
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 15, 2021, 03:41:59 pm
Northern Honshu

E4A
a) Add exit 5-2
b) On other roads you used X and Xa as waypoint names for complex junctions like 5-1.  I do think E45 is more descriptive than 5-1a.

E4AMic
a) Its correct.  I spent way more time on this one than I expected.  Looking at it on GSV had me skeptical - it isn't an expressway and looks more like a NH state highway through the White Mountains.  After some searching I did find multiple references to it being part of E4A.

E7
a) Waypoint E8/E42 should be E8/E49.

E7Oda
a) Waypoints 17 and 18 should be 26 and 27.

E13Inn (for Innai)
a) This is a new segment of E13, between E13Mas and E13,
b) Waypoints N13_S and N13_N

E13Mas
a) N13_Yaz, N13_Kam could be N13_N, N13_S

E45
a) Combine E45 and E45Ota. The connecting roadway opened in March.
b) Add exits 26, 27, and 28.  You might need 28 and 28a because the two sections of the exit are separated by a tunnel.
c) Move waypoint 25 to the exit. It is at the former end point.
d) Delete waypoint N45_KM.
e) N45_N could be just N45.
f) Waypoint 2 could be E6.

E45Hac
a) Consider using the exit number - 65 - instead of N45/N395_S

E46
a) Add exit 3-1(Aki)
b) Waypoint 1-1(Aki) is an exit to a rest area. It probably should be removed.
c) Waypoint 5-1(Aki) could be named E7
d) The Toki waypoints could be named 37(E4), 37-1(E4), and 38(E4)

E64Aji
a) Waypoint ToN101 should be moved east to the intersection with N101. The waypoints could then be N101_W, P31, N101_E
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 15, 2021, 05:15:57 pm
I rechecked E28 and E30.

It looks like E30 does connect to an E2 stub
Hayashima IC 隣 (next to)
    E2 - Sanyo Expressway Kurashiki Hayashima Branch Line
        (16) Kurashiki JCT - (1) Hayashima IC/TB
    E30 - Seto Chuo Expressway
        (1) Hayashima IC/TB - Tsubue PA - (2) Mizushima IC

Also, the description for the Kurashiki exit of the Sanyo Expressway says that it connects to the Sanyo Kurashiki branch and that it goes "in the direction of" E30.


But the data is conflicting on whether E28 connects directly to E2 with no stub, though I suspect the Kobe-Nishi IC info is wrong.
Kobe-Nishi IC 隣 (next to)
    E28 - Sanyo Expressway Kimi Branch Line
        (2) Miki JCT - (1) Kobe-Nishi IC
    E28 - Kobe Awaji Naruto Expressway
        (1) Kobe-Nishi IC/TB - (2) Fusehata JCT/IC

The Miki JCT next to info however, says that the exit goes onto an E2 stub.
    E2 Sanyo Expressway Main Line
        (1) Kobe-Kita IC - (2) Miki JCT - (3) Miki-Higashi IC
    E2 Sanyo Expressway Kimi Branch Line
        (2) Miki JCT - (1) Kobe-Nishi IC

Also, the description for the Kimi exit of the Sanyo Expressway says that it connects to the Sanyo Kimi branch and that it goes "in the direction of" E28.


Google Maps and OSM show the E2 stubs.   I think they do exist.  I'd be glad to volunteer to field check.

A sign like this https://www.google.com/maps/@34.8076878,135.071515,3a,30.2y,34.42h,99.82t/data=!3m7!1e1!3m5!1sUmfO1VHC5q_8YTwAfb2KyQ!2e0!5s20191201T000000!7i16384!8i8192 (https://www.google.com/maps/@34.8076878,135.071515,3a,30.2y,34.42h,99.82t/data=!3m7!1e1!3m5!1sUmfO1VHC5q_8YTwAfb2KyQ!2e0!5s20191201T000000!7i16384!8i8192) also shows E1A and E2A, which are not reached for many kilometers. I think the E28 here could be similar - its a "to" reference.

I think the E28 here could be similar - its a "to" reference.
But so could the E2 signage at the other end.

The bar is a little higher when it comes to spurs - it needs something on the road saying it that without a doubt is actually a spur.

I've found this E2 confirmatory sign (https://www.google.com/maps/@34.6235188,133.7953695,3a,15y,126.08h,87.02t/data=!3m6!1e1!3m4!1sn2KPDGoSy3zb8G-2lEK4Iw!2e0!7i16384!8i8192) heading away from the E2 towards the E30. That is enough evidence for that. I'll have a look at the E28 one and see is there's similar.

I'm glad you found that confirmation marker.  It gives me more confidence about OSM and Google Maps show for expressways.

I just GSV traveled both directions on the E2-E28 connector and did not see any signs saying E2 or E28. The expressway numbering plan was announced in 2016. GSV was mostly from 2017-18 which might be too soon after the announcement for signs to be present.  You have better GSV foo than me, so you might find something if you look.

The GSV road name overlay did switch over from E2 to E28 at km 9.3 just N of the toll booth, which proves only that Google thinks there is a spur.  At that location northbound, there was a sign saying "From here, Sanyo Expressway" which is the E2 on its main line.  Again, not conclusive.

Another inconclusive data point:  The 2016 expressway numbering plan lists only the Kobe Awaji Naruto Expressway as part of E28. That expressway ends at the Kobe-Nishi IC.
Title: Re: jpne: Japan Expressways
Post by: nezinscot on April 16, 2021, 10:47:15 am
The other Honshu-Shikoku connector is E76.  It seems to connect directly to E2 at IC22. 

Anecdotal evidence:
E2 does not list a branch line for this IC.
The toll booth is just after the exit, not KMs further south like on E28 and E30.
The 2016 numbering document lists three roads as making up E76 - the northernmost one is N2.
The IC22 wikipedia page says that it connects to E76 and N2.

I have no suggested changes for either E76 or E76Sai.

I will be in Tennessee for the next two weeks and likely won't be able to review more roads till I return.

More northern Honshu

E6
a) Waypoint 1(Job) could be C3/SE6.  SE6 is the thru road.
b) Waypoint 10-1 should be 10-1(Job)
c) Add exits 19-1(job), 20-1(Job), and 20-2(Job)

E48
a) E48 does not exist between waypoints 9 and 10. Need to split it into two entries.
b) E48 ends at waypoint 9
c) Add exit 7-1(Yam)

E48Tsu (Tsuruoka) - new entry
a) Starts at waypoint 10

E49
a) Add exit 2-1
b) Waypoint 14 should be E7/E8
c) Add a new waypoint 14, ~1 km north of E7/E8, at the bridge.

E80
a) no changes

E4 correction
a) Waypoint 1 could be called SES1/C3 or C3/SES1.  SES1 is the continuing road.  (My original suggestion used S1, not SES1)

Post by: nezinscot on May 02, 2021, 04:24:36 pm
I'm back from Tennessee and a visit to the New River bridge in WV.

E1
a) Add exits 4-1, 6-1, 7-2, 10-1, 15-2, 16-1, 16-3, 19-3, 21-1, 25-3, and 26-2.
b) Current waypoint 4-1 should be named 4-2.
c) Current waypoint 7-2 should be named 7-3.
d) Current waypoint 16-1 should be named 16-2.
e) Current waypoint 19-1 should be named 19-2.
f) Waypoint 1 could be called SE3.
g) Waypoint 38 could be called HE3.
h) Exit 30-2 has two separate interchanges - Seta Nishi (W) and Seta Higashi (E). Maybe add a 30-2a waypoint for Seta Nishi similar to what was done for exit 7.

E1A
a) Add exits 10-1(STE) and 13-1(STE).

E1A - possible new branch
a) I believe the connecting road from 3(SME) to E23 is a stub of E1A. OSM and GSV both mark it as E1A, but I could not find any confirmatory signage along the road using GSV. The Japanese wiki page for the Kameyama West interchange also says that the connector is part of E1A.

E1AEbi
a) Waypoint 1 could be named C4.
b) Waypoint 5-1 could be named E1_Ise, similar to how you named E1_Got on E1A. Isehara is the junction name.

E1AKaw
a) Waypoint E1 could be named E1_Tak. Takatsuki is the junction name.
b) Waypoint 5-1 could be named E2.

E1AYaw
no changes

E2
a) E2A_E could be named E1A.  E2 is a direct continuation of E1A.  Or if you wish to keep the E2A reference, maybe use E2A_Kob (Kobe junction).
b) E2A_W could be named E2A_Yam (Yamaguchi junction).
c) Add exits 14-1, 21-1 and 29-1

E2 - possible new branch
a) Exit 32-1 (Hatsukaichi IC) is on a branch that leaves from exit 32 (Hatsukaichi JCT). The Hatsukaichi JCT and IC wiki pages both say that the branch is part of E2. I think that exit 32-1 being at the end of the branch infers that it is more a short branch route and not a very long exit ramp.

E2Ube
a) Waypoint E2A could be E2A_Shi. Shimonoseki is the junction name.


E2 - combine with E2Ube
a) E2 seems to follow the Ogoori Bypass and Yamaguchi-Ube Road from Yamaguchi Minami IC (exit 41) on the E2 to Ube JCT (exit 42) on E2Ube. If you concur, we need to combine E2 and E2Ube into one entry and add waypoints for the ICs between exits 41 and 42.
b) If E2 does connect to E2Ube, then the section of E2 from Yamaguchi-Minami IC (41) up to E2A becomes a branch route of E2.

The Japanese wiki pages for the two roads indicate that they are part of E2.

OSM sparsely shows E2 symbols on the two roads. Google Maps does not mark the Ogoori Bypass as E2, but the GSV road name overlay does show both the roads as being part of E2. As usual, in GSV I could find no mention of E2 on signs on the two roads.

https://search.w-nexco.co.jp/en/map.php shows E2 using the two roads. Nexco is the company that manages the toll expressways, so they would know where E2 is routed.

E2A
a) Add exits 18-1 and 32-1.
b) Waypoint 2 has two exit areas, 2 km apart. Consider using two waypoints - 2 and 2A.
c) Waypoint 38 should probably be located closer to P72, south of the tunnels.

E3A, E3AYat - second review
Maybe use E3_N for the first waypoint in E3AYat and E3_S for the last waypoint in E3A. Or E3 for the first waypoint in E3AYat and 26 for the last waypoint in E3A. The expressway will at some point be continuous; the missing sections are under construction.

E4A, E4AAom - second review
Maybe use E4_S for the first waypoint in E4A and E4_N for the 54 waypoint in E4AAom.

f) Waypoint 1 could be called SE3.
g) Waypoint 38 could be called HE3.
If there is an exit number that's in the sequence of the rest of the road, I will always use that rather than a road name. I'll use the road name if it's the exit numbering from the other road, or there's no exit number.

Though the entity managing the non-toll roads don't seem to think it's E2. And I think its worse than merely non-signed as E2, but actively not signed: at the western end (https://www.google.co.uk/maps/@33.9917957,131.3173556,3a,27.6y,347.15h,95.75t/data=!3m6!1e1!3m4!1sINsQpPMI8ro7pWlMy1Q9Ww!2e0!7i16384!8i8192?hl=en) E2 is only signed on the bit mapped, and not on the Yamaguchi-Ube Road.

Post by: nezinscot on May 05, 2021, 02:29:52 pm
Thanks for letting me know the rule for naming the end exits when in sequence.

I just found this sign from 2020 GSV (not present in 2018).  It indicates that the Yamaguchi-Ude road south of Kagawa IC is E2.
https://www.google.com/maps/@34.0551082,131.3501619,3a,67.6y,77.26h,98.1t/data=!3m6!1e1!3m4!1sAhh1jvp1646kV5BnQRs3_Q!2e0!7i16384!8i8192

The best written reference I have found so far is the Sanyo Expressway wiki page.  E2 follows the the Sanyo Expressway for most of its length.  The page says that E2 follows the two roads, connecting the Fukida-Yamaguchi Line of the Sanyo/E2 with the Ube-Shimonoseki Line of the Sanyo/E2.

The Ube JCT wiki page says that the Yamaguchi-Ude road is E2 when it leaves the junction.  The Yamaguchi Minami IC wiki page says that the Ogoori Road is E2 when it leaves the IC.  The wiki pages for the two roads say they are part of E2.  Of course, all this only proves that wikipedia is internally consistent about the roads.

E8
a) Add exits 14-1, 23-1, and 40-1.

E9
a) I would add (KJE) - for Kyoto Jukan Expressway - to the waypoint names for exits 1 thru 17. Most of these numbers are also used on the sections of E9 that are part of the San-In Expressway.

E9Ham
a) Nob is not an exit. It goes to a rest area.

E9Iwa
a) Ota could be named P27.
b) N9_E could be named N9_Iwa (from Iwami IC).
c) P43 could be named N9_Fuk (from Fukube IC).

E9Kus
a) N9 could be named N9_Tou (from Touta IC).

E9Mas
a) N9 could be named N9_Suk (from Suko IC).

E9Mat
a) Add exit 10-1.

E9Hig, E9Kam, E9Nag, E9Oda, E9Sam, E9Tot, E9Yun
-- No changes

E11
a) Add exit 3-1(Tak)

E14
a) Waypoint E51 should be 7-1.
b) I think waypoint 9 should be 8a and 9a should be 9.  I think the exit from current waypoint 9 is the northbound exit piece of waypoint 8.
c) Add exit 18-1.

E14Kis - new branch
a) A short branch of E14 starting at waypoint 17 with three waypoints 17, 17-1, and N16. Kis is from the road name Kisarazu South Branch Line.

E16
-- No changes

E16Nam
a) The KanZoo exit only goes to the Nature Park parking lot. It does not connect to other roads.

E17
a) Add exits 3-1 and 7-1.

E18
a) Add exit 14-1.

E19
a) Add exits 6-1(Nag), 24-1(Cen) and 25-1(Cen).

E20
a) Add exits 3-2, 9-1 and 15-1.
b) Exit 5 has two components that the expressway wiki page and OSM label as exits 5-1 and 5-2. 5-1 is a westbound exit onto P16. 5-2 is the current waypoint 5.

Title: Re: jpne: Japan Expressways
Post by: nezinscot on May 06, 2021, 10:00:45 pm
E1AKam - new branch
a) Extends from E1A waypoint 3(SME) to E23 waypoint 32-1. The junction wiki pages both call the connector E1A, as does OSM. The connector is considered part of the Shin Meishin Expwy which is assigned E1A by the expressway numbering scheme. Kam is from Kameyama Connecting Road. The connector is 5km long, so I think it is too long to be considered an exit ramp.

E23
a) Add exit 32-2, an exit from the rest area. It is just north of waypoint E25.
b) Ramps for 32-2, 33, and E25 are so intertwined I can’t decide where the waypoints should be and how many there should be. I defer to your experience.  (The Higashi Meihan Expwy wiki page has 32-2 connecting to P786, and 33 being the connection to E25 and N1.)
c) Add exit 39-2.

E24
a) Waypoint Gose should be named P116.
b) Waypoint N35 should be named P35.

E24Shi
a) Add a waypoint at the Miyake IC between 8 and 9. It is very near where E24 crosses the railroad and river. The exit connects to the Kashihara Bypass beneath E24. The bypass is an alternate branch of N24.

E24Kyo
-- No changes.

E25
a) I think using (MHE) or (Mei) would be better than (Osa) for the waypoints on the eastern part of E25. This part of the road is the Meihan Expressway.
b) I think (NME) or (NMH) would be better than (Nin) for the waypoints on the western part of E25. This part of the road is the Nishi Meihan Expressway.
c) Consider using exit 29(MHE) instead of 6(Nin). The Meihan Expwy has an exit 29 at the Tenri IC.  Or you could add exit 29 where N25 meets P51, just east of N169.

E26
a) Add exit 2. It is N of the river at Settsu Minami IC (IC shown on Google maps)
b) I think waypoint 7 is part of the exit 6 system.  Waypoint 7a should be waypoint 7, although it needs to be moved S a little to be at the exit.
c) Add exit 12.  It is where P36 exits/enters E26, just N of 12-1.

E27
a) Add exits 12-1 and 15.

E29, E29Tat
No changes

E31
a) Waypoint 3-1 is slightly too far south.
b) Waypoint 3-2 is slightly too far north. The exit is not at P66.

E32
a) Add exit 5-1.

c) Waypoint 19(THE) should be named E8. The value 19 is from E8, not the THE.
d) The (Nag) waypoints should probably use (Noe) . The highway is the Noetsu Expressway.
e) Add exit 4-1(Noe).

E41Ana
a) Yok could be named P23

E42Shi
a) N46 should be named P43.
b) Sano could be named Shin from Shinguu Minami IC.

E42Wak
a) Add exits 21-1 and 28-1.

E50
a) Add exit 4-1
b) I checked waypoint 21 on 2020 GSV and the final IC is not given a number. Consider using P6/P62.  The Hitachinaka toll road wiki page also shows a numberless final IC.

E51
a) Waypoint 10 should be named 9-1. Exit 10 is a SIC off of N295 onto E65 just east of the 9-1 JCT, and is defined as a waypoint on E65.

E55
a) Waypoint N44 should be named P44.

E55Kik
a) N55_S could be named N55_Kon (from Konou IC)
b) N55_N could be named N55_Hiw (from Hiwasa exit/entrance).

E55Tan
a) N493_S could be named N493_Kas (from Kashiwagi IC).
b) N493_N could be named N493_Shi (from Shibasaki IC)

E56
a) Add exit 14-1.

E56Shi
a) Use the exit numbers 26, 27, 28 instead of N56_Nak, P344, and N56_Hir.
b) Add exit 29.

E64
a) There’s a stoplight at the N7 intersection. The Japanese wiki page for the expwy says that they have discussed building an IC here, but there are currently no plans in place.

E64Aji
a) N101_E could be named N101_Kiz (from Kizukurikoshimizu town)
b) N101_W could be named N101_Aji (from Ajigasawa IC)

E65
a) I would position waypoint N295 closer to the Exit 10 SIC ramps.

E67
a) N158 could be N158_Abu (from Aburasakatouge exit).
b) Add (E41) to waypoints 10, 11, 11-1, 12, and 13.
c) P471 is not part of E67. This section of E67 ends at N41.

E67Eih
a) N157 should be named N158_Oon (from Oono IC). The expwy continues onto 158.  157 meets 158 a short distance away.

E67Hir
a) N158 could be named N158_Nak (from Nakanoyu IC).

E68

d) N136/N414_Gat could be named N136/N414_Tsu (from Tsukigase IC)

E71

E73
a) 15(Chu), 16(Chu), 17(Chu) should be 15(E2A), 16(E2A), 17(E2A).

E74
a) I believe E74 ends at 4(Ham)..  The section between 4(Ham) and N9 is not part of the Hamada Expwy.

E75
a) Add exit 4-1.

E76
-- No changes

E76Sai
-- No changes

E81
a) Add exit 1-1.

E82
a) Exit 1 is an entrance from N16, which is beneath E14. Add E14 as the initial waypoint before exit 1, and move waypoint 1 to where the onramp from N16 meets E82.
b) Exits 5-1 and 6 are intertwined. 5-1 is the exit for C4 and exit 6 is where E82 continues onto N126.

E83
a) There is no exit 3 yet (2025). Remove waypoint 3.
b) The off-ramp part of exit 6 is S of the current waypoint, through the parking area. There is about 0.5 km between the two halves of exit 6. Either have a 6 and 6a or move the waypoint into a more central location.
c) N1_Min is not in Mineoka.  It is in Tokiwadai town Yokohama, so maybe use N1_Tok instead of N1_Min.
d) Add exit 8. It is exit only going N.  I found exit 8 signs on GSV. http://www.openstreetmap.org/?lat=35.468639&lon=139.592946 (http://www.openstreetmap.org/?lat=35.468639&lon=139.592946)
e) Add exit 9. It is exit only going S. On GSV exit signs say Mineoka and do not have the exit number 9 on them.  http://www.openstreetmap.org/?lat=35.465979&lon=139.591526 (http://www.openstreetmap.org/?lat=35.465979&lon=139.591526)
f) Add exit 10. It is entrance only going S. I found exit 10 signs on GSV. http://www.openstreetmap.org/?lat=35.460082&lon=139.587280
g) According to the expwy wiki page, waypoints Kaw and P401 are exits 14 and 15. I could find no exit numbers using GSV.
h) N1_Hod is not in Hodogaya. It is in Kamiyabe town Yokohama, so maybe use N1_Kam instead of N1_Hod.

E84
a) N134 could be named N134_Oiso (from Oiso town) to differentiate it from the N134 in E84Chi.
b) ToN135 could be named N1_OIK (from Ooisoko IC) - the N1 part is admittedly a stretch
c) N1_Oiso could be named N1_OIH (from Ooiso Higashi IC)
d) N1_Nin could be named N1_OIN (from Ooiso Nishi IC)
e) P71 is exit 1.
f) N1_Tac is exit 2.
g) P72 is exit 3.
h) P719 is exit 4.
i) N1_Oda is exit 5.
j) ToN135 is exit 6.
k) Remove N135. It is not an exit.
l) ManRd should be HakTpk (from Hakone Turnpike). “With its many sweeping corners and twists, the turnpike is an internationally renowned destination for sports car drivers, the Japanese motoring press, drifting enthusiasts and other local speed aficionados.”
m) E85 is exit 7.
n) N1_Iry is exit 8.

E84 new branch
A branch of E84 heads south following the Ishibashi Branch Line from exit 6 to N135 at exit 9 in Ishibashi.  Its either a new branch or a very long exit.

E84Chi
a) N134 could be named N134_Yan (from Yanagishima) to differentiate it from the N134 in E84.

E85
a) Use the exit numbers from 1 to 9. E84 is exit 1. E1 is exit 9.

E86
a) Uch could be named P326.
b) Add the exit at Uchinada Shirahodai, between Uch(P326) and P56. http://www.openstreetmap.org/?lat=36.673126&lon=136.651211 (http://www.openstreetmap.org/?lat=36.673126&lon=136.651211)

E87
a) N23 could be named NE3/N23.
b) MinChiRd could be named ForMinChiRd.  The Minami Chiba Road starts at the Handa IC at the next exit south of this IC.
c) Rin could be named P522_Rin and the waypoint could be moved slightly north to be more central between the N and S parts of the IC.
d) P522 could be named P522_Cen (from Centrair Higashi IC)

E88
a) Waypoint 6 should be moved NE.  http://www.openstreetmap.org/?lat=34.904780&lon=135.767387 (http://www.openstreetmap.org/?lat=34.904780&lon=135.767387)
b) Waypoint 7 should be named E89.
c) Add waypoint 7 (exit 7) about 1km W of E89.  http://www.openstreetmap.org/?lat=34.898839&lon=135.740573 (http://www.openstreetmap.org/?lat=34.898839&lon=135.740573)
d) Waypoint 8 should be moved NE  http://www.openstreetmap.org/?lat=34.895776&lon=135.723116 (http://www.openstreetmap.org/?lat=34.895776&lon=135.723116)
e) I think that E88 ends at the waypoint currently named E9.  The connections to E1 are from that IC, so maybe rename this waypoint to E1/E9 and remove the E1_W waypoint.

E89
a) According to the Daini Keihan Road Japanese wiki page, the 80# waypoints are not part of E89.  E89 begins at waypoint 1, I’d guess at or near the toll booth.  The Road Bureau map also shows E89 ending near waypoint 1.
b) If you decide to retain the 80# waypoints, they should have a dash between the 8 and the 0.

E90
a) Add exit 4.  http://www.openstreetmap.org/?lat=34.512546&lon=135.443970 (http://www.openstreetmap.org/?lat=34.512546&lon=135.443970)
b) P216 is exit 3.
c) Add exit 2.  http://www.openstreetmap.org/?lat=34.512308&lon=135.481435 (http://www.openstreetmap.org/?lat=34.512308&lon=135.481435)
d) P61 is exit 1.
e) These exit numbers are listed on the expwy wiki page, but I could find no use of them in GSV 2020 views.

E91
a) After waypoint 6, E91 continues east on the Yamato Takada Bypass, ending at the Shijo Ramp.  http://www.openstreetmap.org/?lat=34.502857&lon=135.788224 (http://www.openstreetmap.org/?lat=34.502857&lon=135.788224)

E92
a) Add exit 3.
b) Use the exit numbers for the existing waypoints.. N170 is exit 1.  N308 is exit 5.  Maybe flip the road direction so that the waypoints ascend.

E93
-- No changes

E94
a) E94 does not extend past E28 to waypoint 2.
b) Waypoint 3 should be named E28.  3 is an E28 exit number.

E95
a) The first waypoint should be named N2
b) Add waypoint 1 at exit 1. http://www.openstreetmap.org/?lat=34.801788&lon=134.743288 (http://www.openstreetmap.org/?lat=34.801788&lon=134.743288)
c) Current waypoint 7 should be named E2A.
d) Add waypoint 7 at exit 7.  http://www.openstreetmap.org/?lat=34.941271&lon=134.760645 (http://www.openstreetmap.org/?lat=34.941271&lon=134.760645)

E97
-- No changes

C2
a) E1A(5) could be E1A_E
b) E1A(10-1) could be E1A_W.
c) Current waypoint 5 should be 5-1.
d) Add exit 5. It is just south of current waypoint 5. It is an exit to P60. http://www.openstreetmap.org/?lat=35.166422&lon=137.006464 (http://www.openstreetmap.org/?lat=35.166422&lon=137.006464)
e) Waypoints 15,16,17 should be 14,15,16.
f) Add waypoint 17 at exit 17. It is an exit to N22.  http://www.openstreetmap.org/?lat=35.222160&lon=136.861539 (http://www.openstreetmap.org/?lat=35.222160&lon=136.861539)
g) Add a waypoint between waypoints 17-1 and 18.  The exit is considered the western part of exit 17 - the two parts are separated by 17-1.  http://www.openstreetmap.org/?lat=35.220617&lon=136.844759 (http://www.openstreetmap.org/?lat=35.220617&lon=136.844759)

C2Hon

C3Oga
a) Waypoint P213 should be 17.  P213 is exit 17.

I did a second review of expressways E90 thru E98.

E95
a) Add exit 15.  14 and 15 are somewhat intertwined, but 15 meets/leaves local roads north of 14.
    15 http://www.openstreetmap.org/?lat=35.187210&lon=134.791877

E98
a) There is an on-ramp before waypoint P367 that could merit its own waypoint.

Second review of expressways E70 thru E89.

E70
a) Rename current waypoint 8 to N136 and move it to the end of the expwy.
    N136 http://www.openstreetmap.org/?lat=35.080214&lon=138.929608
b) Add exit 8
    8 http://www.openstreetmap.org/?lat=35.094933&lon=138.946152

E71
a) Switch the names of waypoints 3 and 4.  Exit 3 is the junction with HE4.  Exit 4 connects P63/Train station to E71.

E77
a) There are multiple intersections with N218 along the finished and in-progress pieces of E77.
    N218_W could be named N218_Kur (from Kurata intersection)
    N218_E could be named N218_Mai (from Maino IC)

E77Tak
a) There are multiple intersections with N218 along the finished and in-progress pieces of E77.
    N218 could be named N218_Unk (from Unkaibashi intersection)
    ToN218 could be named N218_Hin (from Hinokagefukasumi IC)

E83
a) Kaw is exit 14.  I found a sign for exit 14 on GSV.  I did not find signs for exit 15. 
    https://tinyurl.com/y2arpsuy

E84
a) I made a mistake in the first review by using the exit numbers shown in OSM and not checking them with GSV.  Using GSV (2020 images) I could find no use of exit numbers on any of the exit/entrances to E84. The wiki pages and what ministry docs I could find don’t show exit numbers either.  Reverting the exit numbers back to the names you originally used gives this:

E85

Second review of expressways E50 thru E69

E56
a) The exit order for E56 is opposite to that for the other E56 units.  E56Ich, E56Koc, and E56Shi are clockwise, while E56 is counterclockwise.  The expressway numbering doc lists the Kochi end first (E56Koc) and Matsuyama end last (E56), so I would flip the exit order for E56.

E58
a) The branch from exit 1-1 to exit 1 is the end section of the Okinawa Expwy.  Is it a branch or just a long exit? Exit 1 is at the end of it.  The Naha Airport Road was appended to E58 at junction 1-1 in 2000.  Exit 1 was probably the original southern end of E58.

E60
a) Shaping point +X766541 probably isn’t needed.

E61Bih
a) Waypoint P122 could be renamed to N39/N240.  GSV signage makes no mention of P122, even at the intersection of it and N39/N240.

E67Eih
a) Consider renaming ToN364 to N364_Eih (Eiheiji).  The connector is similar to the connector for (no “To”) N416_Shi.

E69
a) P298 could be renamed to ToP298.   P298 is not close to the very rural exit.

Second review of expressways E40 thru E49

E41
a) Current waypoint 1(THE) should be named E1.
b) Add exit 1(THE) where E41 connects to P14.
    1(THE) http://www.openstreetmap.org/?lat=35.281225&lon=136.781150

E42Wak
a) The waypoint order for E42Wak is opposite to that for the other E42 units.  E42, E42Kum, and E42Shi are clockwise, while E42Wak is counterclockwise.  The expressway numbering doc lists the E42Wak end last, so I would flip the waypoint order for E42Wak.

E44
a) Consider using N44_Onn (Onnetou IC) and N44_Nem (Nemuro IC) instead of N44_W and N44_E.

E45
a) N45_N could be named N45_TaM (from Tanohata Minami IC).  (There is no corresponding N45_S.)

E46
a) Waypoint 1-1(Aki) is not an exit. it goes to a service area.
b) Consider flipping the order of the waypoints. The Akita end is listed last in the numbering document’s definition of roads making up E46.

E48
a) Add exit 7-1(Yam) and remove the shaping point just to its west.
    7-1(Yam) http://www.openstreetmap.org/?lat=38.366720&lon=140.259452
b) E48 does not exist between waypoints 9(Yam) and 10(Yam).  E48 should end at 9(Yam).

E48Tsu - new segment
a) Add route E48Tsu (from Tsuruoka), starting at 10(Yam) of the current E48.

E49
a) Add exit 2-1 and remove the shaping point just north of it. 
    2-1 http://www.openstreetmap.org/?lat=37.370558&lon=140.603902
b) Rename waypoint 14 to E7/E8.  This is junction 42, not exit 14.
c) Add exit 14.  It is 0.8 km N of the junction, just S of the bridge. 
    14 http://www.openstreetmap.org/?lat=37.878182&lon=139.037148

Second review of expressways E20 thru E39

E27
a) Waypoint E2 should be named E2A.

E28
a) There is no waypoint for Exit 4-1.  I assume you decided 4-1 is part of 4.

E29
a) E29 does not exist between current waypoints 3-1 and 3-2.  The route should be split into two parts. 
    This yellow sign says that the next 2km is a general national highway
    https://www.google.com/maps/@35.2195311,134.3230236,3a,90y,122.7h,97.35t/data=!3m6!1e1!3m4!1senVDOjWipl8y2nEW-LkgYQ!2e0!7i16384!8i8192 (https://www.google.com/maps/@35.2195311,134.3230236,3a,90y,122.7h,97.35t/data=!3m6!1e1!3m4!1senVDOjWipl8y2nEW-LkgYQ!2e0!7i16384!8i8192)
b) Waypoint 3-1 should be named N373_Sak (from Sakane intersection).  On GSV I did not find any signs using 3-1 or 3-2.
c) Waypoint 3-2 should be named N373_Kom (from Komagaeri intersection).

E30
a) On GSV and on the expwy wiki page, waypoints 3-1, 3-2, and 3-3 do not use exit numbers.
    Exit 3-1 could be named Hit (from Hitsuishijima IC).   Signs say “islanders only”.
    Exit 3-2 could be named Iwa (from Iwakurojima IC).  Signs say “islanders only”.
    Exit 3-3 could be named Yos (from Yoshima IC).  Access to the parking area is allowed.

E31
a) Add exit 1. 
    1 http://www.openstreetmap.org/?lat=34.360334&lon=132.497227
    GSV of the little green sign in the median at the point where the Hiroshima-Kure Road (E31) starts - this is exit 1:

E34
a) The N3 and N34 waypoints could be named 1(Nag) and 1a(Nag), or N34 could be eliminated and N3 renamed as 1(Nag).  GSV shows that exit 1 goes to N3.  N34 only connects to E34 via shared on-ramps with N3 that meet E34 quite a ways west of N3.
    1 http://www.openstreetmap.org/?lat=33.393917&lon=130.528629
    1a http://www.openstreetmap.org/?lat=33.397034&lon=130.517326  - at merge point

E35Fuk
a) There is an on-ramp between FEC and waypoint N202_Jur.  JE stands for Jurokucho Entrance.
    N202_JE http://www.openstreetmap.org/?lat=33.568495&lon=130.312326
b) Consider renaming N202_W to N202_MH (from Maebara Higashi IC).

Second review of expressways E10 thru E19, plus E78.

E13Mas
a) N13_Masu could be named N13_Nak (from Nakada IC).  Also, datacheck says N13_Masu contains a long underscore.
b) N13_Kaz could be named N13_Noz (from Nozoki IC)
c) What does the Masu of E13Mas derive from?  I couldn’t find a nearby location starting with Masu. This section is mostly in Kaneyama town of Mogami district.  E13Kan or E13Mog might be better names.

E13Yok
a) N13_San could be named N13_Mit (from Mitsuseki IC)
b) N13_Cro could be named N13_Jum (from Juumonji IC)

E14Kis
a) Waypoint N6 should be named N16.

E19
a) E19 is defined as starting at the Nagoya end. The waypoint order should be reversed.

E78

Second review of expressways E1 thru E9

E1
a) Should the name of shaping point +2 be longer?
b) Ham is not an exit. It goes to a service area.

E1A
a) There is a secondary IC to P50 near the Nagoya Minami JCT (exit 5) on the Ise Expwy.
    5a(Ise) http://www.openstreetmap.org/?lat=35.045852&lon=136.952828
b) Add exit 7-1(Ise)
    7-1(Ise) http://www.openstreetmap.org/?lat=35.051785&lon=136.895897
c) Exit 10(Ise) has three parts. The JCT with C2 is 10-1 and there are units of IC 10 on either side of the JCT.  I’m not sure if they warrant being separate entries.
    10(Ise) http://www.openstreetmap.org/?lat=35.051843&lon=136.824905

    10a(Ise) http://www.openstreetmap.org/?lat=35.051858&lon=136.807550

E2
a) Waypoint Sab is not an exit. It goes to a service area.

E2Ube
a) Possibly add the Yamaguchi-Ube and Ogoori Roads to E2Ube, connecting Yamaguchi Minami IC on E2 with Ube Higashi IC on E2Ube.

GSV 2020 image on N2 heading east at the Kagawa exit of the Yamaguchi-Ube Road shows that the Yamaguchi-Ube Road heading south from this junction is considered to be part of E2.  (I have not found similar images for the Ogoori Road.)

2019 Picture at 500m to Ube JCT (next to last photo) on E2Ube shows the Yamaguchi-Ube Road is part of E2.  (GSV is 2018 and has an older sign that does not say E2.)   http://fuwafuwaame.sakura.ne.jp/road/EXP/A/sanyo-exp/up/p1'/p1'.html (http://fuwafuwaame.sakura.ne.jp/road/EXP/A/sanyo-exp/up/p1'/p1'.html)

E2a
a) Move waypoint 1 to
    1 http://www.openstreetmap.org/?lat=34.807419&lon=135.534993
b) Move waypoint 2a to
    2a http://www.openstreetmap.org/?lat=34.804151&lon=135.433354

E5Toy
a) To better differentiate it from other N40 waypoints on E5, waypoint N40 could be renamed to N40_Toy (from Toyotomi Kita IC)

E5a
a) According to the expressway road numbering document, the start of E5A is in Kuromatsunai and the end is in Sapporo.  Consider reversing the order of the waypoints. (From what I could gather, E5A is decades from ever being finished, so maybe keeping the existing ascending exit ordering would be better.)
b) Maybe use E5_N for the first waypoint in E5A and E5_S for the last waypoint in E5AKur

E5aKur
a) According to the expressway road numbering document, the start of E5A is in Kuromatsunai and the end is in Sapporo.  Reverse the order of the waypoints if you also do so for E5A.
b) Maybe use E5_N for the first waypoint in E5A and E5_S for the last waypoint in E5AKur
c) Waypoint N5 should be named N5_Kur.  If ever completed, E5A will intersect N5 many times, so a more specific name is probably better.

E6
a) Waypoint 10-1 should be named 10-1(Job)
b) Add exit 19-1(Job)
    19-1(Job) http://www.openstreetmap.org/?lat=37.283083&lon=140.981351
c) Add exits 20-1(Job) and 20-2(Job) 
    20-1(Job) http://www.openstreetmap.org/?lat=37.411295&lon=140.962223
    20-2(Job) http://www.openstreetmap.org/?lat=37.458253&lon=140.962408

E8Ham
a) P330 could be renamed N9_Got (from Goutsu IC).  N9 is the continuing road; P330 is a minor connector.
b) N9_Kas could be renamed to N9_Har (from Harai IC)
c) N9_Mih could be renamed to N9_Mis (from Misumi).  Miho is not mentioned on signs, Misumi is.

E9
a) Waypoint 17(KJE) should be moved to a position between the north and south parts of the exit.
    17(KJE) http://www.openstreetmap.org/?lat=34.914986&lon=135.686768
b) The northern part of exit 13(KJE) is half a km from the current waypoint which is at the southern part of the exit.  Maybe add a new waypoint 13a(KJE)?
    13a(KJE) http://www.openstreetmap.org/?lat=35.013127&lon=135.557524

E9Hig
a) Consider renaming N178_E to N178_Igu (from Igumi IC).
b) Consider renaming N178_W to N178_Hig (from Higashihama IC)

E9Mat
a) Rename waypoint 17(SIE) to 16a(SIE).  On GSV, the junction is signed as exit 16.
b) Add exit 17(SIE). 
    17(SIE) http://www.openstreetmap.org/?lat=35.422451&lon=133.379868

Second review of the circular expressways.   All national expressways have now been reviewed twice.

C2Hon
a) The first waypoint should be named 5-1, not 5.

C4Mob
a) C4Mob begins at waypoint 93. The road to N126 is not part of C4.


And a concurrency check on AH1

Concurrencies
a) AH1 should show a concurrency with FE4 in Fukuoka between FE1 and N201
b) AH1 should show a concurrency with SE3 in Tokyo between 307 and SEC2
c) AH1 should show a concurrency with SEC1 in Tokyo between SE3 and SE4
d) AH1 should show a concurrency with SEC1 in Tokyo between SEY and SE6

Finding a bunch of weird waypoint names with a shell script led me here...

E71
a) Switch the names of waypoints 3 and 4.  Exit 3 is the junction with HE4.  Exit 4 connects P63/Train station to E71.
Yup. Sure enough, the EB exits are signed out of order (https://www.google.com/maps/@34.4147144,135.2938964,3a,16.2y,130.96h,95.37t/data=!3m9!1e1!3m7!1sDtRNQ_xzvKKxcUyXZW6bAg!2e0!7i16384!8i8192!9m2!1b1!2i40).
The repositioning of Exit 4 (https://github.com/TravelMapping/HighwayData/commit/46ad6b04e31#diff-76b434a17637ad98e71316002bf612d1e1ef5f49088c2d3cb7be66528873621e) caught my eye. I was almost going to suggest folding 4 into 3, One-Point-Per-Interchange ("1PPI"), but...
Initially, it looks like the new point position is where an elevated roadway touches down onto a surface road -- see how that darksalmon-colored roadway with the black outline meets the lightsalmon-colored roadway? Red herring more like; this looks like some bizarre OSM fiction. Look at Google/GMSV and you'll just see single roadways.
The first intersection as the ramp comes down off the viaduct is at P29/63 (https://www.google.com/maps/@34.4110693,135.2996181,3a,17.4y,133.95h,93.5t/data=!3m9!1e1!3m7!1sqLIKdXxPikE64GY972By2w!2e0!7i16384!8i8192!9m2!1b1!2i40)... so moving the point back to its original location would yield a graph connection (with N481 now; assuming the P routes (Prefectual Roads?) will be drafted later). Things do look quite a bit Texas right here. :)
