Struct map_model::objects::lane::Lane

pub struct Lane {
    pub id: LaneID,
    pub parent: RoadID,
    pub lane_type: LaneType,
    pub lane_center_pts: PolyLine,
    pub width: Distance,

}

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

Fields

id: LaneID

parent: RoadID

lane_type: LaneType

lane_center_pts: PolyLine

width: Distance

dir: Direction

src_i: IntersectionID

dst_i: IntersectionID

bus_stops: BTreeSet<BusStopID>

Meaningless order

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

impl Lane

pub fn first_pt(&self) -> Pt2D

pub fn last_pt(&self) -> Pt2D

pub fn first_line(&self) -> Line

pub fn last_line(&self) -> Line

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

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

pt2 will be endpoint

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

pub fn length(&self) -> Distance

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

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

pub fn is_driving(&self) -> bool

pub fn is_biking(&self) -> bool

pub fn is_bus(&self) -> bool

pub fn is_walkable(&self) -> bool

pub fn is_sidewalk(&self) -> bool

pub fn is_shoulder(&self) -> bool

pub fn is_parking(&self) -> bool

pub fn is_light_rail(&self) -> bool

pub fn get_directed_parent(&self) -> DirectedRoadID

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

pub fn trace_around_block(
    &self,
    map: &Map
) -> Option<(Polygon, BTreeSet<LaneID>)>

Starting from this lane, follow the lane’s left edge to the intersection, continuing to “walk around the block” until we reach the starting point. This only makes sense for the outermost lanes on a road. Returns the polygon and all visited lanes.

TODO This process currently fails for some starting positions; orienting is weird.
