Struct game::edit::traffic_signals::gmns::Snapper

struct Snapper {
    roads_incoming: HashMap<DirectedRoadID, Pt2D>,
    roads_outgoing: HashMap<DirectedRoadID, Pt2D>,
    movements: BTreeMap<MovementID, Movement>,
}

Snaps a line to a vehicle movement across an intersection. It uses movement endpoints and a hint about turn type to match.

OSM IDs aren’t used to snap, because GMNS and A/B Street may disagree about where a road segment begins/ends. This could happen from OSM IDs changing over time or from different rules about importing things like service roads.

Fields

roads_incoming: HashMap<DirectedRoadID, Pt2D>

roads_outgoing: HashMap<DirectedRoadID, Pt2D>

movements: BTreeMap<MovementID, Movement>

Implementations
