Book excerpt: This Interim Circular has three purposes: (1) to provide current information on the status of ongoing research conducted in the United States and Europe for unsignalized intersection capacity and to identify areas where further applied research is required; (2) to describe a procedure for conducting capacity analyses at all-way stop-controlled intersections and to encourage its use so users and the TRB Committee on Highway Capacity and Quality of Service can judge its applicability to the variety of circumstances not represented at the underlying research sites; and (3) to provide traffic engineers with a standard data collection technique for both all-way stop-controlled and two-way stop-controlled intersections which can be used in the United States to collect a more comprehensive data base for unsignalized intersection capacity/delay characteristics. This technique should define the data which must be collected to lead toward revision of Chapter 10 of the Highway Capacity Manual.
