Struct map_model::Turn

pub struct Turn {
    pub id: TurnID,
    pub turn_type: TurnType,
    pub geom: PolyLine,
}

A Turn leads from the end of one Lane to the start of another. (Except for pedestrians; sidewalks are bidirectional.)

Fields

id: TurnID

turn_type: TurnType

geom: PolyLine

Implementations

impl Turn

pub fn conflicts_with(&self, other: &Turn) -> bool

pub fn angle(&self) -> Angle

pub fn between_sidewalks(&self) -> bool

pub fn penalty(
    &self,
    constraints: PathConstraints,
    map: &Map
) -> (usize, usize, usize)

Penalties for (lane types, lane-changing, slow lane). The penalty may depend on the vehicle performing the turn. Lower means preferable.

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

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

Is this turn legal, according to turn lane tagging?

pub(crate) fn permitted_by_road(&self, i: &Intersection, map: &Map) -> bool

Is this turn legal, according to turn restrictions defined between road segments?

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

If this turn is a crosswalk over a single road, return that road and which end of the road is crossed.

Trait Implementations
