Allow/ban cyclists on individual bike lanes #184

Open matkoniecz opened 4 years ago

matkoniecz commented 4 years ago

Is it viable to configure it per city or per lane? For example in Kraków cyclists are banned from bus lanes.

Maybe it would be useful to explicitly tag in OSM via bicycle:lanes.

This happens at https://github.com/dabreegster/abstreet/blob/c20e3701391eff7b679e6919d595c4e6b7ecee38/map_model/src/pathfind/mod.rs#L447. I think it's time to pull driving_side from Map into some per-city config that also has bikes_can_use_bus_lanes. I can set this up today. Detecting it from OSM tags would be useful; I'd have to talk to the community here about doing a partly automated edit.

Is it viable to set it per lane? At least here in Kraków it would be one of interesting things to check for impact (what can appear on psv lanes is set by city, on per lane basic - and allowing bicycles on some of them requires "only" adding them to list of vehicle types listed on a traffic sign).

But per city settings also would be very helpful, as current state is mismatching reality.

Definitely, but needs some UI adjustments to show on-map (probably a "bus only" "bikes ok" symbol) and some work in the lane editor. There are more advanced per-lane restrictions that should eventually be supported, like no parking 9-6pm or bus-only from 7-7.

I'll put together the per-city setting today, and leave the more granular thing as future work.
