E 552 Intersection Traffic Capacity

Section E 340, Highway Capacity, discusses the use of uninterrupted traffic flow for determination of highway capacity and the modification of this flow when interrupted flow prevails. One of the most important elements creating interrupted flow of traffic on a highway, particularly in urban areas, is the at-grade intersection. These intersections have considerable control of the vehicular and pedestrian traffic flow capacity of all City streets. Therefore, the terms “intersection operation” and “interrupted flow” are often used synonymously.
