C16: Type of Intersection


An intersection consists of two or more roadways that intersect at the same level.

Type of Intersection is used to record and allow separation of various intersection types such as; four-way and t-type intersections.

Intersection - An area which 1) contains a crossing or connection of two or more roadways not classified as driveway access and 2) is embraced within the prolongation of the lateral curb lines, or if none, the lateral boundary lines of the roadways. Where the distance along a roadway between two areas meeting these criteria is less than 10m (33ft.), the two areas and the roadway connecting them are considered to be parts of a single intersection.
