Using grep and shell scripts to search highway data, waypoint labels, etc.

[yakra]

grep is a powerful tool to search for regular expressions in text files. It runs on Unix-like systems such as Linux, FreeBSD (e.g. noreaster) or Macintosh. With a little practice, you can put together expressions to search for very specific types of text strings. In this post, I'll focus on waypoint labels.

Commands were executed from the hwy_data/ directory.
They're designed to easily substitute different regions into the $rg variable, so you can execute the same command different times to search different regions.
rg=PA
grep whatever $rg/*/*.wpt
rg=DE
grep whatever $rg/*/*.wpt
et cetera. You can also wrap them up inside loops to search multiple regions in one go:
for rg in PA DE; do grep whatever $rg/*/*.wpt; done
or
MyRegions='PA DE'
for rg in $MyRegions; do grep whatever $rg/*/*.wpt; done
et cetera.

The cut command was included to strip out AltLabels and URLs from the .wpt file lines, to ensure that we're only searching within primary labels.
If you have questions about the various tokens, expressions or commands, feel free to ask.

Some example search results in Pennsylvania and Delaware are posted here.


Potential no-underscore malformed city suffixes
grep -v '^+' $rg/*/*.wpt | cut -f1 -d' ' | egrep -v '[A-Z][A-Z][0-9]{1,3}Alt|[A-Z][A-Z][0-9]{1,3}Bus|[A-Z][A-Z][0-9]{1,3}Byp|[A-Z][A-Z][0-9]{1,3}Trk|[A-Z][A-Z][0-9]{1,3}His|[A-Z][A-Z][0-9]{1,3}Spr|[A-Z][A-Z][0-9]{1,3}Con' | egrep ':[A-Z]{2}[0-9]{1,3}[A-Z][a-z]{2}'
This one can get confusing.
Edit, 2019-11-18 01:32 EST: Only check primary labels; avoid false negatives.

Intersections with visibly numbered highways

US40: US40BusWhi | US73: US40BusWhi US40BusTho | A3: A3Zur
Distinguish two different same-bannered same-numbered routes as needed with the 3-letter city abbreviations. Also use the city abbreviation for bannerless same-designation spurs or branches, such as the Zurich A3 spur intersecting the main A3.

While we do want to use city abbreviations for routes (in the HB) that have them...

Distinguishing otherwise identical waypoints (not for exit numbers)

US95: NV57_Ren | NV57_Tah
If more than two points for the same non-exit-numbered cross road are needed, there are two options which can be used in combination with or ignoring the previous options for pairs of identical labels.
1. Use alphabetical suffixes _A, _B, _C, etc.
2. Choose 3-letter suffixes for a nearby towns if they are fairly close. The 3-letter suffix should be the first 3 letters of the town name. Add a suffix with an underscore and those 3 letters.

...disambiguating multiple intersections with a single route, or with roads not in the HB, is done with an underscore.
A lot of time, people may use the former when they intended to use the latter.


Underscored 4-character city suffixes not ending in N, E, W, or S
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | grep '_...[A-DF-MO-RTUVXYZa-z]$'
Distinguishing otherwise identical waypoints (not for exit numbers)

NV88_PitS | NV88_PitN
If you need the same town twice, add a 4th letter that is a direction letter (_PitS and _PitN for southern and northern junctions near Pittston). If the town suffixes are not useful, are confusing, or require further elaboration (3+ junctions with same town), use the alphabetical suffixes instead.

Edit, 2019-11-17 20:58 EST: Only check primary labels.


2-character city suffixes
egrep -sv '^\+' $rg/*/*.wpt | cut -f1 -d' ' | grep -v '_U[0-9]$' | grep '_..$'
Edit, 2019-11-17 22:08 EST: Exclude false positives caused by numbered U-turn ramps.


Old highway designation labels
grep -s '^Old..[0-9]' $rg/*/*.wpt
Waypoints for roads that no longer have a name or no longer exist as a road

MainSt
If the old highway has a posted name or number, use that name or number (don't make one up), and label the waypoint according to the usual rules.
If US 30/Main Street becomes Main Street, then the label is MainSt, not something like OldUS30.
OldUS40
If the old highway has a posted name that mentions the old designation, then applying the above rule will result in a label like OldUS40 for "Old Route 40" if the route was formerly US 40.

There will be a good number of false-positive, legitimate labels here.
I'm not sure how closely these rules (if it's a requirement & not an option) have been followed; there are a lot of examples where "OldRt" or "OldHwy", etc. are used if a road is signed as such in the field, or if that's the official name. (Although, Tim may have done it that way before these specific guidelines were codified...) May be something worth discussing in the forum.


Long words, >4 characters
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | egrep ':.*[a-z]{4}'
Intersections with named highways

FaiRd PapMillRd
For up to two other (specifying) words, truncate the word as follows:
1-4 letters - use whole word
5+ letters - use the first 3 letters. Don't use a made-up abbreviation. Fairchild Road becomes FaiRd, not FrchldRd or FchRd or anything else.

Too many words
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | egrep -v ':[A-Z]*[a-z]*Mc[A-Z][A-Z][a-z]*$|:Mc[A-Z]{2,}[a-z]*[A-Z][a-z]*$|:[A-Z]*Mc[A-Z]+[a-z]?$' | egrep '[A-Z]+[a-z]+[A-Z]+[a-z]+[A-Z]+[a-z]+[A-Z]+[a-z]*|[A-Z]+[a-z]+[A-Z]+[a-z]+[A-Z]+[a-z]?[A-Z]+[a-z]+|[A-Z]+[a-z]+[A-Z]+[a-z]?[A-Z]+[a-z]+[A-Z]+[a-z]*|[A-Z]+[a-z]?[A-Z]+[a-z]+[A-Z]+[a-z]+[A-Z]+[a-z]*'
Intersections with named highways

MarKingBlvd MLKingBlvd
If the cross road name has more than 3 words, use one of two options:
1. Pick out the two most important words besides the road type and use only those: Martin Luther King Boulevard becomes MarKingBlvd. Three words in total are included in shortened form.
2. Pick out one important word besides the road type and use it and the initials of the other words: Martin Luther King Boulevard becomes MLKingBlvd. Two words in total are included in shortened form along with initials of the rest.

An older style for 3-word road names was to have Two truncated words & one initial. E.G., Lisbon Falls Village Rd -> LisFalVRd.
This was later deprecated in favor of the rule quoted above. LisFalRd, LFVilRd, etc.
Edit, 2019-11-17 21:40 EST: Use egrep for BSD (e.g. noreaster) compatibility due to + token.


McDonRd
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | grep 'Mc[A-Z][a-z]'
In the above search, the Mc[A-Z] tokens are included to filter out "Old McDonald Farm Rd" style false positives.
OTOH, McDonald is one word, so it makes sense to truncate it to McD, rather than treat it as 2 for McDon.


Tpke for Turnpike
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | grep 'Tpke'
CHM standardized on "Tpk" for turnpike, standard abbreviations notwithstanding...


Directional prefixes
egrep -sv "^\+|^.[a-z]|^$rg[0-9]+" $rg/*/*.wpt | cut -f1 -d' ' | grep ':[NEWS]' | egrep -v ":[A-Z][A-Z]/[A-Z][A-Z]$|:[NEWS]End$"
Intersections with named highways

6thSt | 33rdAve | SeeLn
Ignore any non-essential direction specifier. N. 6th St becomes 6thSt. 33rd Avenue SW becomes 33rdAve. W. Seedy Lane becomes SeeLn.
NorPkwy | SouBlvd
But keep directions that are the main part of the road name, such as NorPkwy for Northern Parkway or SouBlvd for Southeast Boulevard.

What's a "non-essential direction specifier" and what are "directions that are the main part of the road name" can get wibbly-wobbly at times; use your best judgment. Many of these may be legit, but they're worth checking out.
IMO though, N/E/W/S are common enough abbreviations for their respective directions, and there are enough examples of this throughout the data, that I'm not going to call for every WPondRd to be changed to a WestPondRd.


Similarly, a search for suffixed directional specifiers:
egrep -sv '^\+' $rg/*/*.wpt | cut -f1 -d' ' | grep '[NEWS]$' | egrep -v '_|[0-9]{1,3}[NEWS]$|:[A-Z][A-Z]/[A-Z][A-Z]$|:CR[A-Z]$|:Rd[A-Z]$|:Ave[A-Z]$|:I\-[0-9]{1,3}BS$'

Edit, 2019-11-17 20:11 EST: Use cut instead of sed to isolate primary labels. More concise, clear, fast.
Edit, 2019-11-17 21:08 EST: Use grep -s to suppress error messages for regions with no WPTs.
Edit, 2019-11-18 01:07 EST: Use egrep for more human-readable expression strings, particularly with | and {}
Edit, 2019-11-18 01:53 EST: Exclude hidden points from all searches.

Rte(Number) style labels on US Interstates
for file in */usai/*.wpt; do results=`grep -H . $file | cut -f1 -d' ' | grep 'I-[0-9][0-9]*(..*)' | wc -l`; if [ $results -gt 2 ]; then grep -H . $file | cut -f1 -d' ' | grep 'I-[0-9][0-9]*(..*)'; fi; done
One point of confusion can be the two styles of waypoint labeling for concurrencies with Interstate Highways and other exit numbered routes.

Interchanges on exit-numbered highways

I-80: 56 | 87(75) | 89(75) | 63
In multiplexes where the concurrency uses exit numbers from the other highway, put the highway number in parentheses. Drop the letter prefix of the concurrent highway if it is more than one character long: I-75 becomes (75). A5 can stay as (A5).

The vast majority of Interstates (with rare exceptions, most obviously WY I-180) will be exit-numbered routes, and thus fall into this category.

Waypoint labels for multiplexes

US90: LA76 | I-49(45) | I-49(47) | I-49(52) | US40
For non-exit-numbered routes concurrent with a numbered, exit-numbered route, use the concurrent highway designation with the exit numbers in parentheses.

We'll sometimes see this erroneously; this basic (Interstate-to-Interstate only) search is designed to pick up on these cases.
It only prints results for routes with at least 3 such labels: Some routes, such as NY I-490 or ME I-295, have both ends at unnumbered interchanges with the parent route, necessitating this style label. Some routes, such as TX I-69, are not fully exit-numbered yet, and contain some crossroad-style labels.
Right now, it reports some malformed labels in ms.i055.wpt & wi.i041.wpt.


How far down this rabbit hole can we go?
An experiment. A somewhat unwieldy one...

Label lacks generic highway type
grep -sv '^+' $rg/*/*.wpt | cut -f1 -d' ' | egrep 'Old[0-9]+_|Old[0-9]+$'
Label should be OldUS42, OldHwy42, OldRte42, OldME42, etc., not "Old42". This was a datacheck on CHM, but although a comment describing the siteupdate program's DatacheckEntry class mentions a LACKS_GENERIC datacheck code, there's nothing actually implementing it yet.

There are only 4 results project-wide. Not bad.
FL/usaus/fl.us027.wpt: CROld50 (should be WasSt?)
NOR/eure/nor.e18.wpt: *Old70
NOR/eure/nor.e18.wpt: *Old67
NOR/eursf/nor.oslokrimotkri.wpt: *Old70
ON/canon/on.on127.wpt: Old127

[neroute2]

FL/usaus/fl.us027.wpt: CROld50 (should be WasSt?)

It's a numbered county road with Old 50 or Old Hwy 50 in the shield. False positive.

[michih]

NOR/eure/nor.e18.wpt: *Old70
NOR/eure/nor.e18.wpt: *Old67
NOR/eursf/nor.oslokrimotkri.wpt: *Old70

Former location of exit 70 and exit 67. Fine to me.

[yakra]

It's a numbered county road with Old 50 or Old Hwy 50 in the shield. False positive.

Oh wows. I did look for something like that, just not hard enough.

Welcome to the world of insanity in FL.

Could that be considered a form of bannered route?  ;D

[cvoight]

The closest equivalent native to Windows PowerShell is Select-String, which is decently powerful though no grep. Executing from the hwy_data directory, you use Get-ChildItem -Include "*.wpt" -Recurse to feed all the files into Select-String. Your pattern will always start with ^ if searching waypoint labels as that signifies the start of a line, functioning similarly to the cut -f1 -d " " portion of yakra's commands.

For example, executing the following command finds any waypoint labels that start with US- (i.e. US routes with a hyphen between the US and the route number).

Code: [Select]

Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^US-"
Slightly more complicated: find all the waypoints in the US that start with I followed directly by a number. [Note: this is not quite restricted to the US as there are some non-US regions with highway directories that contain the string "usa", but it eliminates most regions and (currently) all false positives. See the code section in this post for a regex that matches only US states and territories.]

Code: [Select]

Get-ChildItem -Directory "*usa*" -Recurse | Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^I[0-9]"

[cvoight]

Pursuant to a point by neroute2 that I had overlooked:

FaiRd, PapMillRd
Truncation rules: abbreviate the generic road type (Rd for Road, Blvd for Boulevard, etc.) if it's one of the very common types. Otherwise, use the first three letters: Uli for Ulica. Skip the final period.

For up to two other (specifying) words, truncate the word as follows:
1-4 letters - use whole word
5+ letters - use the first 3 letters. Don't use a made-up abbreviation. Fairchild Road becomes FaiRd, not FrchldRd or FchRd or anything else.

First, find all waypoints with a capital letter followed by 4 or more lowercase letters, executed from the hwy_data directory: Get-ChildItem -Include "*.wpt" -Recurse | Select-String -CaseSensitive -Pattern "[A-Z][a-z]{4,}" (In actuality, I piped this to a text file by appending | Out-File .\four_lowercase.txt

Scanning this file, I filter the results: delete many odd results from ITA\ita.nsa (2).wpt; delete Minnesota subway lines (MN\usamnmt\BlueLine.wpt & MN\usamnmt\GreenLine.wpt); all lines that contain a + [presumably waypoint alias] -- using Sublime Text, execute a regex search for ^.*\+.*$, select find all, and press delete twice; results from _boundaries directory. This leaves 151 results of which the vast majority are valid. (Some look like simple miscapitalizations -- e.g. CA\usaca\ca.ca001.wpt:299:Fulst, others are more involved. There are quite a few in preview systems, but still many in active systems.)

Many of these errors are in in-development/preview systems, rather than active systems. Many errors in those systems will be picked up and fixed in the peer review process, to get the systems ready for promotion to active status.

In the preview systems I manage, peer review has already picked up all the listed errors, and fixes are in my queue. The two errors in my active systems, one was already in my queue, and the other one has just been added.

@cvoight, thanks for your effort.

We have automated checks which are reported and updated with every site update: http://travelmapping.net/devel/datacheck.php

I just wonder, why some are not detected, e.g.:

@yakra? Any idea, should I open a Github issue?

It's an active system and I'll fix it.

Parenthesizing your Select-String query and appending .length allows you to find the total number of results. For example, to find the number of waypoint labels with a US route as the primary highway (31,265):

Code: [Select]

PS ..\hwy_data> (Get-ChildItem -Directory "*usa*" -Recurse | Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^US").length
31265

US80/42, A5/A6, I-5/6, I-80/90, I-80/6
Putting two highways in a waypoint label: Put the primary highway first, followed by a slash, followed by the second highway. Drop the prefix of the second highway if it is more than one character long. A5/A6 becomes A5/A6. I-5/I-6 becomes I-5/6. I-25/US50 becomes I-25/50.

edit: I redid this post as I did not read the label style guide properly. In fact, I quite bungled it in just about every way! My apologies for any confusion! Real results can be found below.

I actually find the waypoints with prefixes on both sides of the slash more attractive, but this does make for an interesting regex query. First, let's check and make sure we can return results for a general query by seeing if there are any waypoint labels with US routes on both sides of the slash: US<something>/US<something>.

Code: [Select]

PS ..\hwy_data> Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^US.*\/US"

Sure enough, but this regex gives us two false positives (NV and SC). yakra's grep queries use cut -f1 -d " " so that only the primary waypoint label is matched (US50/395 and US521Trk/601Trk_N here). The naive regex I'm been using looks for US at the start of a primary waypoint label, but then matches zero or more of any character (.*) until it finds a /US. Changing .* to [^\s]* (zero or more non-whitespace characters) eliminates the issue as the match will stop once it gets past the primary waypoint label. Success!

Code: [Select]

PS ..\hwy_data> Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^US[^\s]*\/US"

The style guide says to drop the secondary highway's prefix after the slash if it's more than one character long, which is a somewhat simple query. Let us assume two things: (1) the only valid characters for highway prefixes are capital letters and hyphens; (2) a highway waypoint label is composed of a highway prefix followed by a number. So we can start by matching all non-whitespace characters that aren't a + (hidden waypoint label or something, not sure on the terminology) from the start of a primary waypoint label [^\s+] until we find a forward slash \/, then look for any instances where there are two or more uppercase letters followed by a number [A-Z-]{2,}[0-9]. Tying it all together: Get-ChildItem -Include "*.wpt" -Recurse | Select-String -CaseSensitive -Pattern "^[^\s+]+\/[A-Z-]{2,}[0-9]" (88 results using .length).

This is somewhat less interesting than one of the queries I was attempting because I misread the examples: what are the waypoint labels that include the same highway prefix on both sides of the slash? (I had also failed to note that the secondary highway prefix must be 2 characters, bah!) The reason it's interesting is that we get to use a capture group and backreferences! (backreferences actually make regular expressions...not regular, but that's why they're fun!) The pattern we want to construct should match two or more valid highway prefix characters, followed by any number of non-whitespace characters, followed by a forward slash, followed by our first match. A naive construction (([A-Z-]{2,})[^\s]*\/\1) quickly runs into problems due to the way backreferences work (see the section Backtracking Into Capturing Groups from the link): if two different sets of 3+ capital letters are on opposite sides of the slash and any subset of 2 characters is in the same order, a match results. You might see where this is going: borders look like valid highway prefixes to a regex and several border pairings yield matches: BGR/GRC, ALM/ALA, IRN/IRQ, etc. (I like to start testing regexes live and then use test data with regexr to iterate more quickly.)

So, matching highway prefixes alone is not enough, we have to be sure that the waypoint label is a highway. The first thing we do is change [^\s]* to [^\s]+. The + requires that the primary highway prefix be followed by one or more non-whitespace characters instead of zero or more. This screens out the BGR/GRC matches, but not many of the other border matches. If we assume that a highway is distinguished by the presence of a number after the highway prefix, we can screen out the rest of the false matches by requiring a number to appear in the secondary highway label after the secondary highway prefix. So, our final regex is: ^([A-Z-]{2,})[^\s]+\/\1[0-9]. If we tried to use non-whitespace characters [^\s] instead of a number [0-9] after the secondary highway prefix, the borders would still match because letters are non-whitespace. Likewise, trying to match only numbers after the primary highway prefix wouldn't work because many highways have suffixes that don't have to be numbers. (I'm sure this is well-understood information to anyone reading this, but I find it a useful practice to go through the reasoning.) Lastly, we can change our assumptions about what highway prefixes look like and use [^0-9] instead of [A-Z-]: assume any non-digit character can be a highway prefix.

note: I have not evaluated active vs. preview systems for these results, nor do I know whether any of these results need to be changed.

@cvoight, thanks for your effort.

We have automated checks which are reported and updated with every site update: http://travelmapping.net/devel/datacheck.php

I just wonder, why some are not detected, e.g.:

Code: [Select]

@yakra? Any idea, should I open a Github issue?

not yakra, but I did peruse siteupdate.py (this link freezes my mobile browser for those browsing by phone, too much data), specifically the results for datacheckerrors.append which I believe is a comprehensive accounting of all the data checks. Generally, the waypoint label checks currently implemented don't test for consistency with the labeling style guidelines, but rather what I would consider more fundamental errors*, such as more than one slash, unbalanced parentheses, and invalid characters. There are a few checks for consistency, e.g. using "Bus" instead of "BL" or "BS" for business interstates, or the LONG_UNDERSCORE checks (flags _Abcd, _AbcdN type stuff), but nothing comprehensive. It would probably be useful to produce public documentation on the exact rules that throw flags (or maybe this exists and I couldn't find it at first glance).

* for what it's worth, I may be alone in drawing a distinction here, and you may consider these checks to be the same kind of thing.

Regions for the United States and Canada don't have a country prefix, but they can be isolated using an exhaustive OR'd regex. The results can then be piped into Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "<pattern_goes_here>" to scan waypoint labels. The (?: indicates this is a non-capturing group, which doesn't matter much in this instance and could be changed to just (. (We have to group the entire OR'd query so that the beginning of line symbol ^ and end of line symbol $ match properly. Without those symbols, MB would match Zambia ZMB or M[ADEINOPST] would match all of the Mexico MEX- regions.)

Code: [Select]

USA: Get-ChildItem -Directory | Where-Object {$_.name -Match "^(?:A[KLRSZ]|C[AOT]|D[CE]|FL|G[AU]|HI|I[ADLN]|K[SY]|LA|M[ADEINOPST]|N[CDEHJMVY]|O[HKR]|P[AR]|RI|S[CD]|T[NX]|UT|V[AIT]|W[AIVY])$"}
CAN: Get-ChildItem -Directory | Where-Object {$_.name -Match "^(?:AB|BC|MB|N[BLST]|ON|PE|QC|SK|YT)$"}This is more seemly than using a unique system wildcard with Get-ChildItem -Directory "<system_wildcard_goes_here>" -Recurse, which does not exist in the case of the US because AUS A route directories contain the string usa).

I-80, A-73
USA Interstates and Quebec Autoroutes retain hyphens.

We can redo our previous search for primary waypoint labels for interstates that lack a hyphen (already posted up, so I won't repost the results of the query):

Code: [Select]

PS ..\hwy_data> Get-ChildItem -Directory | Where-Object {$_.name -Match "^(?:A[KLRSZ]|C[AOT]|D[CE]|FL|G[AU]|HI|I[ADLN]|K[SY]|LA|M[ADEINOPST]|N[CDEHJMVY]|O[HKR]|P[AR]|RI|S[CD]|T[NX]|UT|V[AIT]|W[AIVY])$"} | Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^I[0-9]"
To check the primary waypoint labels for Quebec autoroutes, we can slim down our Where-Object query because we only care about QC:

Code: [Select]

PS ..\hwy_data> Get-ChildItem -Directory | Where-Object {$_.name -Match "^QC$"} | Get-ChildItem -Include "*.wpt" -Recurse | Select-String -Pattern "^A[0-9]"No results, so all the primary waypoint labels for QC autoroutes (450 results) meet the style guidelines.
