2c5bbd3e7e Use alternate language building names and amenities, when available. Fixes #271. 
Tested in Shinjuku. No substantial file size increase for any maps.

24a8d4a836 Prepare to support capping the number of vehicles that can pass through 
a zone per hour. This is part of support for some kind of congestion
charging experiments. This step just rearranges the data to define the
cap and makes a UI to edit it. Not enforcing the cap yet.

d427893843 Model parking lots with extra un-renderable spots. This fixes #150, lots 
without aisles, and #265, multi-story garages.

40ddd06194 Improving the on/off ramp geometry by preferring that the "thin" road is 
one of the outbound roads. This was motivated by one particular example
in downtown, and per screenshot tests, doesn't have regressions
elsewhere. Also improves a few cases in montlake.

83e84c10af Handle more errors in importer. Got the entirety of Taiwan to import... 
but the water polygons are so sad. :(

25ee39af89 Prepare to flag-guard an experiment to handle uber-turns differently 
when allowing a car to start a turn. It causes
https://github.com/dabreegster/abstreet/pull/276#discussion_r470269394
and also the lakeslice scenario to gridlock (a regression that began a
few weeks ago). But keep the flag on for now, to keep the montlake
scenaro running at least.

https://dabreegster.github.io/abstreet/trafficsim/gridlock.html has
notes about the many different causes and in-progress fixes for
gridlock. This experiment hasn't been explained very well yet, but
roughly it treats a cluster of traffic signals as one, so that once a
vehicle gains access through the first light, they guarantee immediate
access through the entire sequence. This interacts with the "don't block
the box" behavior (don't start a turn if you might get stuck in the
intersection) strangely.

While attempting to get this rollback to work, I also had to manually
redraw the traffic lights for a few manually specified intersections.
They became out-of-date a few weeks ago when I cleaned up the OSM
geometry upstream and the referenced IDs changed, and I hadn't bothered
to re-time the signals. Luckily, with the new multi-signal editor,
redrawing the timing was much easier than originally!

Regenerated all data and lots of bus routes vanished. Plan to get back
to that project soon.

c84833feb4 More steps on the multi-signal editor, adapted from the old editor: 
- Add a header to the side panel
- Prevent leaving the editor with missing turns
- Apply edits properly when leaving

11cefb118a And the same thing for OriginalIntersection 
Actually, don't need to regenerate map data. Thanks to the magic of
zero-cost wrapper types, the binary format is the same.

843d24b6ed Refactor: OriginalBuilding should just be OsmID. The purpose of 
OriginalBuilding was to refer to buildings in a stable way across
different maps and across OSM updates. Recently, OsmID and friends
appeared. The double layer of wrapping is an annoying API.

Not regenerating map data yet; about to do the same thing for
OriginalIntersection

58849d3d15 Small refactor: in most places, we can actually use String as the error type; Box<dyn Error> is only useful when errors of different types are propagated. 
Nowhere in abst do we care about handling different errors differently

3b49353df2 gracefully degrade if we cant make TurnGroups for a traffic signal. this

62bb82886d blaze through all the crazy errors in intersection_polygon, just 
recording errors and falling back to circular geometry and not trimming
roads

also filter out highway areas like
https://www.openstreetmap.org/way/132705692, woops!

Manchester and NOLA now import...

a27b029ff6 plumb errors for shifting polylines through more APIs. mostly no-op for 
now, just switched everything to must_* variants, but this paves the way
for handling failures.

... except for rendering pedestrian crowds -- I _think_ I saw a crash
from that, and it's easy to have a fallback there

8764226765 cutover to using the new stuff for snapping bus stop positions... 
seems pretty good for a few examples. not regenerating yet. still lots
of routes skipped because of edge cases, but now it's way more clear
how to work on those smaller problems.

5998afaea4 interpret some OSM turn restrictions as meaning no lane-changing on approach to turn lanes. deeply sanity-checked for monlake only, seems reasonable from spot checks elsewhere 
closes #261 -- not sure it's worth actually handling changes:lanes yet,
but this fixes the original issue

cd712009ec whittle down old stuff from map_editor. i think it still has value as a RawMap viewer with an easy way to move points and quickly iterate on intersection geometry, but things like lane editing and turn restriction viewing aren't useful anymore. 2020-08-05 08:38:04 -07:00

940d2265c0 spawning buses at 0.01m on a non-border lane can break, because other cars approach, and the buffer distance gets broken. instead, spawn the buses a few lanes away, if needed. fixes #260 
now only ~400 agents left in lakeslice by end!
