Enum map_model::IntersectionKind

pub enum IntersectionKind {
    MapEdge,
    Terminus,
    Connection,
    Fork,
    Intersection,
}
Expand description

What kind of feature an Intersection actually represents. Any connection between roads in the network graph is represented by an Intersection, but many of them are not traffic “intersections” in the common sense.

Variants§

§

MapEdge

A Road ends because the road crosses the map boundary.

§

Terminus

A single Road ends because the actual roadway ends; “the end of the line”.

E.g. turning circles, road end signs, train terminus thingos, …

§

Connection

Multiple Roads connect but no flow of traffic interacts with any other.

Usually one Road ends and another begins because the number of lanes has changed or some other attribute of the roadway has changed. More than two Roads could be involved, e.g. when a single carriageway (a bidirectional Road) splits into a dual carriageway (two oneway Roads).

§

Fork

One flow of traffic forks into multiple, or multiple merge into one, but all traffic is expected to keep flowing.

E.g. highway on-ramps and off-ramps.

§

Intersection

At least three Roads meet at an actual “intersection” where at least one flow of traffic gives way to, or conflicts with, another.
