Expand description

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

Fields§

§id: LaneID§lane_type: LaneType§lane_center_pts: PolyLine§width: Distance§dir: Direction§src_i: IntersectionID§dst_i: IntersectionID§driving_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§

source§

impl Lane

source

pub fn first_pt(&self) -> Pt2D

source

pub fn last_pt(&self) -> Pt2D

source

pub fn first_line(&self) -> Line

source

pub fn last_line(&self) -> Line

source

pub fn endpoint(&self, i: IntersectionID) -> Pt2D

source

pub fn end_line(&self, i: IntersectionID) -> Line

pt2 will be endpoint

source

pub fn dist_along_of_point(&self, pt: Pt2D) -> Option<Distance>

source

pub fn length(&self) -> Distance

source

pub fn intersections(&self) -> Vec<IntersectionID>

source

pub fn number_parking_spots(&self, cfg: &MapConfig) -> usize

source

pub fn is_driving(&self) -> bool

source

pub fn is_biking(&self) -> bool

source

pub fn is_bus(&self) -> bool

source

pub fn is_walkable(&self) -> bool

source

pub fn is_sidewalk(&self) -> bool

source

pub fn is_shoulder(&self) -> bool

source

pub fn is_parking(&self) -> bool

source

pub fn is_light_rail(&self) -> bool

source

pub fn is_footway(&self) -> bool

source

pub fn get_directed_parent(&self) -> DirectedRoadID

source

pub fn get_nearest_side_of_road(&self, map: &Map) -> RoadSideID

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.

source

pub fn get_lane_level_turn_restrictions( &self, road: &Road, force_bus: bool ) -> Option<BTreeSet<TurnType>>

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.

source

pub fn common_endpoint(&self, other: &Lane) -> CommonEndpoint

source

pub fn get_thick_polygon(&self) -> Polygon
