Expand description

A road segment is broken down into individual lanes, which have a LaneType.

Fields

id: LaneIDlane_type: LaneTypelane_center_pts: PolyLinewidth: Distancedir: Directionsrc_i: IntersectionIDdst_i: IntersectionIDdriving_blackhole: bool

{Cars, bikes} trying to start or end here might not be able to reach most lanes in the graph, because this is near a border.

biking_blackhole: bool

Implementations

pt2 will be endpoint

This does the reasonable thing for the leftmost and rightmost lane on a road – except for roads with exactly one lane. For lanes in the middle of a road, it uses the direction of the lane – so bidirectional/contraflow cycletracks will produce weird results.

Returns the set of allowed turn types, based on individual turn lane restrictions. None means all turn types are allowed.

This will return None for bus lanes, unless force_bus is true. OSM turn restrictions on bus lanes usually apply to regular vehicles, not the buses. When generating the turns for buses, we probably don’t want to use the restrictions.
