1) Mode choice is fixed, coming from https://www.psrc.org/activity-based-travel-model-soundcast https://www.psrc.org/activity-based-travel-model-soundcast. Next work focus will be on adjusting mode choice when edits make it favorable to bike/walk. Route assignment is mentioned in https://dabreegster.github.io/abstreet/how_it_works.html https://dabreegster.github.io/abstreet/how_it_works.html (documenting all assumptions in an organized way has been really hard). There are score functions in https://github.com/dabreegster/abstreet/tree/master/map_model/src/pathfind https://github.com/dabreegster/abstreet/tree/master/map_mode... -- they're pretty simple right now. 2) I wrote a bit here: https://old.reddit.com/r/urbanplanning/comments/hdylmo/ab_street_a_traffic_simulation_game/fvo4wrj/ https://old.reddit.com/r/urbanplanning/comments/hdylmo/ab_st...
