Angular Intersection - woven-planet/opensafety-mbse GitHub Wiki

Were it not for roundabouts, we wouldn’t need this classification. But there is a clear distinction between the way circular and non-circular intersections behave. In an attempt to capture all non-circular intersections, T-intersections included, the qualification “angled” seemed appropriate. (You can’t call them “square” or even “rectilinear” as many non-circular intersections are not. We could try “polygonal”, but a T-intersection has no such shape.

Here are a couple of real world examples. Note that each is built around a polygonal (angular) shape.

Signalized

Describes the system for gating traffic through the Intersection. If a priority scheme is used, indicated with physical signs or a regionally established prioritization scheme, we consider it a non-signalized Intersection. If we have a signalized Intersection, then scrambled pedestrian activity may or may not be supported. In the case of a signal scramble, all Interfaces will forbid traffic for a period of time so that pedestrians can occupy the interior of the Intersection. This is most common in the business districts of metropolitan areas. Most signalized intersections are signal no scramble which means that traffic is permitted to flow through at most times with alternating pedestrian access via Crosswalks.
