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 a~d and
reference source for persons who are assigned the responsibility of
conducting traffic conflict observations at intersections.
Based on previous research and experiences, the sur~ey techniques
described in this manual provide a standard, cost-effective method [or
accurately observing and recording traffic confllcts. The manual contains
definitions with illustrations and ex.arnp~es of con.flic~ tyl)es, and
instructions for conducting the field actlv~tles, lncludlng 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 inter--
preting the results of conflict surveys, are presented in the engineer Is
guide (FHWA-Ip-88-026)e
