Dustin Carlino 1a05da2824 Change how pathfinding works when avoiding modal filters. 
Before, it was just a large 3 hour penalty for crossing a filter -- so
it shouldn't happen, but it was possible, and so some (but not all!) LTN
code had an extra paranoia step to filter out paths that crossed.

Now, actually make it impossible at the pathfinding layer.

Also, fix colors in the LTN pathfinding tool that were backwards

A/B Street

Ever been stuck in traffic on a bus, wondering why is there legal street parking instead of a dedicated bus lane? A/B Street is a project to plan, simulate, and communicate visions for making cities friendlier to people walking, biking, and taking public transit. We create software to simulate traffic, edit streets and intersections, plan bike networks, create low-traffic neighborhoods, and educate the public about 15-minute neighborhoods through games. The project works anywhere in the world, thanks to OpenStreetMap.

Project mission

We amplify the efforts of individuals and advocacy groups who campaign to transition cities away from private motor vehicles. We believe in transparent and reproducible analysis, so all of our work is open source and based on public data. We believe everybody should have a voice in shaping their city, so our software aims to be easy to use.

Why not leave city planning to professionals? People are local experts on the small slice of the city they interact with daily -- the one left turn lane that always backs up or a certain set of poorly timed walk signals. Laura Adler writes:

"Only with simple, accessible simulation programs can citizens become active generators of their own urban visions, not just passive recipients of options laid out by government officials."

Existing urban planning software is either proprietary or hard to use. A/B Street strives to be highly accessible, by being a fun, engaging game. See here for more guiding principles.
