ch	Uses https://github.com/easbar/fast_paths. Slower creation during map importing, but very fast queries.
dijkstra	Pathfinding without needing to build a separate contraction hierarchy.
node_map	Some helpers for working with fast_paths.
pathfinder
uber_turns	To deal with complicated intersections and short roads in OSM, cluster intersections close together and then calculate UberTurns that string together several turns.
v1
v2	Structures related to the new road-based pathfinding (https://github.com/a-b-street/abstreet/issues/555) live here. When the transition is done, things here will probably move into pathfind/mod.rs.
vehicles	Pathfinding for cars, bikes, buses, and trains using contraction hierarchies
walking	Pathfinding for pedestrians using contraction hierarchies, as well as figuring out if somebody should use public transit.

Tuneable parameters for all types of routing.

Who’s asking for a path?

Heavily penalize crossing into an access-restricted zone that doesn’t allow this mode.
