usaca: California State Highways

(1/86) > >>

Prior discussion of this in-dev system is on the AARoads forum at http://www.aaroads.com/forum/index.php?topic=16761.0  Links to the route files (some very rough) in the system are at http://tm.teresco.org/devel/hb.php?sys=usaca

Current status: I just finished updates of all the state's Interstate and US routes. As I munch through the state routes to update them, I can copy revised waypoints from the updated I- and US routes to synch them with the state routes. I've already done this with CA 299, a major route where I've done the kind of updating that will be done for other state routes.

First, though, two steps before I turn to revising the state routes, and getting them ready for review:

-- Replacing the placeholder files for some of the routes added to the draft system that was in CHM, including CA 59 and a bunch of business routes I found. The placeholders map to a short route in a Russian city, which is good to flag their "placeholder" status but creates other issues such as a map of usaca routes that reaches to the other side of the globe. So I'll replace them with real route files.

-- Figuring out how to deal with relinquishments, a discussion started at AARoads. This gives me headaches every time I dive into it, to work out a consistent approach on how to treat them. Complicating this is the disappearance, for some of the older relinquishments, of the continuation signage local jurisdictions were supposed to maintain on the roads they took over from CalTrans (the presence of such signage was something I thought might justify ignoring most of the relinquishments).

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

Here's a partial summary including links. etc. for the sources I'm using for this system and for maintaining already-active Interstate and US routes in CA, besides the usual resources applicable to other U.S. and non-U.S. jurisdictions such as OSM and Google Maps Street View. This list can be moved into a replacement for the Sources and Links page on the CHM website.

Daniel Faigin's California Highways hobbyist site

AARoads California Roads and Highways pages

AARoads Interstate Business Route Guide (includes both California and other states)

California Streets and Highways Code sections 300-635 (legislative route definitions, and authorized relinquishments to local governments)

Caltrans' California Log of Bridges on State Highways (2015, includes some of the information from the old paper-only highway logs)

Caltrans' California State Highways Logs for districts 1-12 (paper only, 2002 version which is the latest available)

Caltrans' Cal-NExUS (California Numbered Exit Uniform System) freeway exit lists

Caltrans' State Highway System Signing Log (from 1991, seriously outdated, but may be latest and only complete list of business routes, so it's better than nothing -- as you might gather, Caltrans isn't real consistent about putting information online or keeping it current)

Caltrans' Transportation Concept Reports (detailed route descriptions, though coverage is incomplete, and some reports are incomplete or outdated)

Coordinates from my handheld GPS receiver (will be used in rare instances where open-source online maps do not accurately show route ends or intersection locations)

oscar:
My latest pull request should have (I'll need to double-check) replaced all the route set's "placeholder" files with real route files. That means the route set can be mapped, without having the map veer off into St. Petersburg, Russia.

This was one issue that had ruled out moving usaca from in-dev to preview status. But I wouldn't do that just yet. There are still major routes requiring reroutes or other significant work, as well as lesser routes needing various levels of polish-up. Also, I need to work out how to deal with route relinquishments, though I've already truncated the routes (like CA 14U and CA 54) that most clearly needed to be shortened. To my mind, usaca shouldn't graduate to preview status until it's ready for peer review, which it isn't.

oscar:
I'm still gradually updating the existing route files. But a note on my overhaul of the most "heavyweight" route file in usaca and maybe in all of TM, for the 700-mi+ and often curvy CA 1 coastal route:

Old file: 48.6K, with 735 waypoints (448 visible, 287 hidden)
Svelte new file: 24.6K, with 369 waypoints (330 visible, 39 hidden)

Once I get the new file uploaded (still trying to fix my GitHub setup), it will definitely lose the heavyweight route file title. New leader might be the main BC BC97 route file, at about 42K for a 1300-mi+ route (not counting the northern end which zigzags several times into and out of Yukon Territory).

Was CA 259 removed?

Yes, as unsigned except as "To CA 210" or "To I-215" (callbox codes and postmiles not enough for our purposes). I checked it out pretty thoroughly when I was out there in February, in hopes of hanging on to it, but no joy.
