Urban corridors, as they exist today, often include a freeway with a supporting netowrk of arterial, collector, and local streets. In some cases, a freeway may not be present, leaving arterial streets as the main carriers of long distance trips. The importance of the arterial street is also shown by the fact that large urban freeway building programs are no longer being carried on in many of the major U.S. cities, thus placing an even greater load on existing and future arterials. Experience inducates that the definition of, and boundaries for, quality of service and capacity for freeways as set forth in the 1965 Highway Capacity Manual are deemed adequate for the highway design engineer's use. There appears, however, to be less confidence and uniformity evident in the use of similar criteria for arterial streets. For this reason a portion of this research study dealt with the capacity and quality of service on arterial streets. The research study reported herein recognized the importance of the signalized intersection as an element in determining overall corridor level of service, and to this end a part of the research was set aside to review the state-of-the-art and recommend methods of determining levels of service at signalized intersections. The study examined a number of aspects of intersection capacity and provided determinations.
