Abstract

This examination of the utility of the traffic-conflict technique includes an evaluation of previous studies and a discussion of recent results of a Federal Highway Administration (FHWA) study. The FHWA study attempts to develop a rigorous experimental design by using traffic conflicts as the basic response variable to measure the effectiveness of implementing various access-control techniques. Although some of the studies conclude that the traffic-conflict technique is a reliable tool for predicting accident potential, these conclusions are not well supported. The concept of conflict analysis should not be abondoned, however, but a more rigorous data base should be acquired before the reliability and utility of conflict analysis can be assured.
