Traffic Operations at Two-Way Stop-Controlled Intersections. Volume 4. TDIPTraffic Data Input Program

摘要

The 1985 Highway Capacity Manual (HCM) includes procedures for analyzing trafficoperations and performance at stop-controlled intersections. However, several significant problems exist with these procedures. Solutions to these problems include defining a new procedure for evaluating two-way stop-controlled intersections based on adequate field data from the U.S., defining a formal procedure for evaluating all-way stop-controlled intersections, and defining a measure of effectiveness such as delay, that is common to all types of intersections. In an effort to move toward these solutions the Idaho Transportation Department and the University of Idaho jointly initiated a series of research projects related to stop-controlled intersections. The problem to be addressed in the project is the development of procedures to evaluate level of service and capacity of two-way stop-controlled intersections through empirical and simulation models. The volume describes the Traffic Data Input Program, a computer program used for collecting traffic volume data and vehicle delay data.
