INTEGRATION OF SAFETY AND THE "HIGHWAY CAPACITY MANUAL"

Users of the "Highway Capacity Manual," which is the primary tool used for analysis and design of highway facilities in the U.S., make recommendations and decisions that affect highway safety. Yet, their decisions are made based primarily on operational measures using the level of service concept. This paper examines the major issues involved in integrating safety into the Manual, characterizes the ideal traits of an assessment tool based upon that discussion and presents a prototype methodology for Chapter 9 - Signalized Intersections. Fuzzy sets are proposed as one tool that has the characteristics described. An example using Fuzzy sets illustrates some of the main tasks required for implementation and, at a conceptual level, describes the various models used.
