Book Description
This manual provides basic background information and step-by-step procedures for conducting traffic conflict surveys at signalized and unsignalized intersections. The manual was prepared as a training aid and reference source for persons who are assigned the responsibility of conducting traffic conflict observations at intersections. Based on previous research and experiences, the survey techniques described in this manual provide a standard, cost-effective method for accurately observing and recording traffic conflicts. The manual contains definitions with illustrations and examples of conflict types, and instructions for conducting the field activities, including time schedules, forms, and other details. The results of traffic conflict observations are used to diagnose safety and operational problems and to evaluate the effectiveness of treatments. Observer training techniques, as well as procedures for analyzing and interpreting the results of conflict surveys, are presented in the engineer's guide.

Book Description
Traffic accidents are the ideal measure of safety for a highway location. But attempts to estimate the relative safety of a highway location are usually fraught with the problems associated with the unreliability of accident records and the time required to wait for adequate sample sizes. For these reasons, the Traffic Conflicts Technique (TCT) was developed as a surrogate measure in an attempt to objectively measure the accident potential of a highway location without having to wait for an accident history to evolve. The TCT was originally developed by the General Motors Research Laboratories (GMR) in 1967. It was conceived as a systematic method of observing and measuring accident potential. Conflicts were defined as the occurrence of evasive vehicular actions and characterized by braking and/or weaving maneuvers. This report critically evaluates the state-of-the-art of the TCT and the results of recent attempts to develop a rigorous experimental design using traffic conflicts as the basic response variable to measure the effectiveness of access control techniques at commercial driveways.
