LEVEL OF SERVICE CONSIDERATIONS AT SIGNALIZED INTERCHANGES. HIGHWAY CAPACITY AND LEVEL OF SERVICE. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON HIGHWAY CAPACITY, KARLSRUHE, GERMANY, 24-27 JULY 1991

Capacity analysis of signalized interchanges is not adequately addressed by current Highway Capacity Manual (1985) procedures. Issues such as computer models, level of service, queue spill back, and phasing and timing that must be addressed in conducting an analysis of signalized interchanges are identified. Guidance is given on how to conduct an appropriate capacity and level of service analysis using available tools. Finally, limitations of the current procedures and recommendations for future research are presented.
