Expand description

An intersection connects roads. Most have >2 roads and are controlled by stop signs or traffic signals. Roads that lead to the boundary of the map end at border intersections, with only that one road attached.

Fields§

§id: IntersectionID§polygon: Polygon

This needs to be in clockwise orientation, or later rendering of sidewalk corners breaks.

§turns: Vec<Turn>§elevation: Distance§kind: IntersectionKind§control: IntersectionControl§orig_id: NodeID§incoming_lanes: Vec<LaneID>

Note that a lane may belong to both incoming_lanes and outgoing_lanes.

§outgoing_lanes: Vec<LaneID>§roads: Vec<RoadID>§modal_filter: Option<DiagonalFilter>§merged: bool

Was a short road adjacent to this intersection merged?

§movements: BTreeMap<MovementID, Movement>

source

pub fn is_footway(&self, map: &Map) -> bool

source

pub fn is_cycleway(&self, map: &Map) -> bool

source

pub fn is_degenerate(&self) -> bool

Does this intersection only connect two road segments? Then usually, the intersection only exists to mark the road name or lanes changing.

source

pub fn is_deadend_for_driving(&self, map: &Map) -> bool

Does this intersection connect to only a single driveable road segment?

source

pub fn is_deadend_for_everyone(&self) -> bool

Ignoring mode of travel, is this intersection only connected to one road?

source

pub fn get_incoming_lanes( &self, map: &Map, constraints: PathConstraints ) -> Vec<LaneID>

source

pub fn get_outgoing_lanes( &self, map: &Map, constraints: PathConstraints ) -> Vec<LaneID>

Strict for bikes. If there are bike lanes, not allowed to use other lanes.

source

pub fn get_zorder(&self, map: &Map) -> isize

Higher numbers get drawn on top

source

pub fn get_rank(&self, map: &Map) -> RoadRank

source

pub fn get_road_sides_sorted(&self, map: &Map) -> Vec<RoadSideID>

source

pub fn get_sorted_incoming_roads(&self, map: &Map) -> Vec<RoadID>

Return all incoming roads to an intersection, sorted by angle. This skips one-way roads outbound from the intersection, since no turns originate from those anyway. This allows heuristics for a 3-way intersection to not care if one of the roads happens to be a dual carriageway (split into two one-ways).

source

pub fn some_outgoing_road(&self, map: &Map) -> Option<DirectedRoadID>

source

pub fn some_incoming_road(&self, map: &Map) -> Option<DirectedRoadID>

source

pub fn name(&self, lang: Option<&String>, map: &Map) -> String

source

pub fn turn_to_movement( &self, turn: TurnID ) -> (MovementID, CompressedMovementID)

Don’t call for SharedSidewalkCorners

source

pub fn find_road_between<'a>( &self, other: IntersectionID, map: &'a Map ) -> Option<&'a Road>
