At-grade intersection
From Wikipedia, the free encyclopedia
An at-grade intersection is a junction at which two or more transport axes cross at the same level (or grade).
[edit] Traffic management
With areas of high or fast traffic, an at-grade intersection normally requires a traffic control device such as a stop sign or traffic light or railway signal to manage conflicting traffic.
[edit] Examples
The various types of at-grade intersections have different names. Examples are intersection (roads), level junction (railways) and railroad crossing (both). Some of them can also mix transportation modalities. An example of this is the railway grade crossing (American English) or level crossing (British English) where a roads cross railways at grade.
