Signalized Intersections and Arterials

Signalized intersections operate with the assistance of a traffic signal, and they cyclically assign the right-of-way to a movement or a combination of movements. Ideally, the amount of time assigned to each combination of movements minimizes the travel time and delay and/or the number of stops in the network and allocates capacity optimally. An arterial is a highway facility with a series of signalized intersections along its length, while an urban network or a surface street network consists of a group of interconnected arterials and side streets.
