I realized my list file now has 3784 lines, which got me wondering how many people have files that long.  Mine is 16th longest.   One user (vespertine) has over 8000 lines, two more are over 7000, two more over 6000, and 2 more over 5000.  94 of our 224 users have at least 1000 lines in their list files.

I should have over 1000 lines (991 right now) once I send in the next update to my list file.

I crossed 1,900 lines with the cross-country trip I just finished. Only added a net of ~105 lines, though, as I closed some gaps in OH and IL as part of it, making the net gain roughly 0 in those states. Next big trip will likely toss me over 2,000, but who knows when that will happen.

I know a "new" user (that most of us know) will likely be getting his account up and running this winter. I would not be shocked if he joins the 5,000+ club once he has everything in, possibly higher.

I guess that the relation of total mileage and lines is more or less similar for all (oscar + mapcat are over 7k).

Not really as something like

TX I-10 NM/TX TX/LA

is 1 line with nearly 900 miles for it, whereas my nearly 900 lines in England gets me less than 6000 miles.

If you've mostly done lengthy routes, and covered most of them, then your .list file is shorter for many more miles than someone who has mostly done short routes, or short bits of routes and so has lots of lines that contribute little to total mileage.

Currently 6776 lines. Never really paid much attention to the "lines." I always just looked at the mileage. I did notice that I have traveled over 75,000 segments as well. Also something I overlooked in the past.

Well, my log file shows 1215 lines. Where as the stats board shows I've traveled 1195 routes.
What's the difference (besides the math)?

[yakra]

Sometimes one line credits you with multiple routes:
ME I-295 4 9
is good for some of US1 and a little ME26.

And sometimes multiple lines only serve one route:
ME I-295 20 22
ME I-295 28 31

Looks like in your case the latter outweigh the former.

Mine currently (well, it will as of the next update) has 1359 lines.

And sometimes multiple lines only serve one route:
ME I-295 20 22
ME I-295 28 31

Looks like in your case the latter outweigh the former.

Probably the same for me, since I include concurrencies where I know about them.

On the subject of lines, I took a trip yesterday that had the net effect of reducing the number of lines on my list by 13...basically filling gaps.

More than 10,000 forum posts now (this is 10,009). And more then 100,000 page views per month.

The longest vertex label in any graph file, at 143 characters:

US129@US129/441BusWat_N&US129BusWat@US129_N&US441@US129/441BusWat_N&US441BusWat@US441_N&GA15@US129/441&GA24@US129/441BusWat_N&GA24BusWat@GA24_N

This is going to be very neato to look at in the HDX-lite and I shall surf it up posthaste!

With the next site update we'll have more than 25,000 routes for more than 800,000 miles in 213 active systems

As of Nov  4 23:42, the WaypointQuadtree contains 46678 total nodes.

No, wait. This number should be 1 + a multiple of 4. Trying again...
62237 total nodes.
46678 would have been the number of bottom-level nodes actually containing waypoints.

[yakra]

Once DataProcessing#122 gets merged, the WaypointQuadtree would have (for that same revision of the HighwayData repo):
42725 total nodes, with 32044 bottom-level nodes containing waypoints.
That leaves 10681 refined nodes that contain no waypoints, but only 4 child nodes.

10681 * 2 = 21362 = the number of edges it would take to make a visual representation of the QuadTree in .tmg format. (+2 for W & E boundaries on the whole thing if you wish, = 21364.) That's a bit smaller than usai-system-simple.tmg.

Taking the simple route and not merging colocated vertices, that's 42724 or 42728 vertices, a bit smaller than ASI-continent-simple.tmg.

Just for fun, I made a graph of the WaypointQuadtree:
http://yakra.teresco.org/tests/tmg/Quadtree/WaypointQuadtree-good.tmg
http://yakra.teresco.org/tests/tmg/Quadtree/WaypointQuadtree-good.tmg.html

https://github.com/TravelMapping/DataProcessing/pull/126/files
The WaypointQuadtree has been initialized all these years with the latitude and longitude bounds swapped. It hasn't broken anything, but just led to a sub-optimal distribution of child nodes.
After fixing it, we're down from 42757 to 35165 total nodes with the latest HighwayData.

How does it affect the time to process the total siteupdate.py time, skipping graphs?
Total run time: [394.3] -> [390.1]
Probably not a significant difference.

Edit: Another fun potential project:
What are the deepest-level, geographically smallest nodes, and how many of this size are there?
Of these, which contain the most waypoints? The most unique locations?

The smallest refined node I've found with a bit of eyeball scanning is near the Maughan Library in Westminster:
Paste this into wptedit for a visual:

Code: [Select]

SW_A http://www.openstreetmap.org/?lat=51.503906&lon=-0.131836
NW http://www.openstreetmap.org/?lat=51.525879&lon=-0.131836
NE http://www.openstreetmap.org/?lat=51.525879&lon=-0.087891
SE http://www.openstreetmap.org/?lat=51.503906&lon=-0.087891
SW_B http://www.openstreetmap.org/?lat=51.503906&lon=-0.131836This node is itself refined into four sub-quadrants.
Which of these contains the most points or unique locations, as well as if there are more nodes of this size (or smaller) elsewhere, will take a programmatic solution.

the Maughan Library in Westminster

1) That is in the City of London - as seen by the City's Crest over its entrance, or the boundaries on the map). OK, over the road is part of the City of Westminster (but see 2).
2) No resident of that urban area would call that part of town over the road 'Westminster'. Most would be surprised to see that it was LB Westminster (even I, a map geek, was somewhat surprised it wasn't LB Camden like the area just to the north)

But other than that, proud that London is the most dense, and surprised it's that bit of it - missing some of the densest bits of Central London's road network and containing a lot of the least dense area within the 'Ring of Steel'.
