e0b6e94f26 In the LTN browse and connectivity tool, draw the areas after the map 
background and water/parks, but before everything else. It's much easier
to understand the actual basemap this way -- you can see roads clearly.

e5704f4a6d Prevent many cases of blocks with overlapping geometry or that extend 
too far, by not trying to trace near railways or cycle-only
bridges/tunnels. This is an imperfect heuristic, but it makes
significant progress in most maps.

231acf47a2 Step 2: try to get the sim crate to build again 
Scenario and TripEndpoint have some methods defined on them that're
specific to sim. Do we rearrange these methods entirely or make some
kind of wrapper types?

e45a5181db Split the "input" layer of the sim crate into a synthetic population 
crate, in preparation for future focus on travel demand models that
incorporate more per-person info.

Note: I'm also a bit tempted to try to further split sim into a
"high-level" layer that orchestrates spawning and different legs of a
trip, from the "low-level" layer that moves pedestrians and vehicles.
That could _possibly_ pave the way for someday using a different traffic
simulation backend with more realistic movement mechanics.

Step 1: just get the synthpop crate to build

e21c57b70a When calculating traffic volumes, deduplicate path requests first. 
Around 2x less paths to calculate.

Even though the deduplication throws away some info, the net effect for
measuring traffic volumes is practically equivalent, so it's a
worthwhile optimization. Used the new comparison UI to verify that!

0203de046d Don't repeatedly try to merge blocks in the select boundary UI. An optimization to workaround new sanity checks introduced for #841 2022-01-26 10:15:31 +00:00

dfbd9785f3 While merging adjacent perimeters for the LTN tool, don't proceed if 
intermediate results can't be turned into a polygon. It'll break
something later. #841

There's a particular bug where a perimeter can be turned into a polygon,
but after collapsing internal dead-ends, it can't.

If we don't do this, the LTN select boundary UI crashes, and reasoning
about block -> neighborhood mappings gets very hairy. I'd like to
address all the root causes of failing to make a polygon, but until
then...

TRADE-OFF: it _really_ slows down the select boundary UI.

eba579dbd1 Adjust the definition of cycleway roads to include sidewalks. Any road 
with only bike lanes and any walkable lane counts as a cycleway, for
rendering purposes. So if you change a road with sidewalks to only allow
bikes on the road, it shows up green in the unzoomed layer.

There's lots of nuance with footways that doesn't matter yet, because
we're mostly not importing those yet.

f777d0ba10 Shift logic from the select boundary UI to the partitioning structure. 
That was the original intention, but it wound up being easier to
prototype otherwise.
