RESEARCH INTO THE VALIDITY OF THE TRAFFIC CONFLICTS TECHNIQUE

This paper examines the conceptual foundations of indirect safety measurement in relation to events such as near-misses or conflicts. The key problem addressed is that of 'validity.' A definition of what validity is to mean is suggested. The statistical machinery for the measurement of validity on the basis of empirical evidence is formulated and tested. With this, it may now be possible to move towards rational consensus about the potential of the Traffic Conflicts Technique and similar procedures for the indirect measurement of safety. As a by-product of the analytical results, a yardstick has been created by which to judge the ralative performance of the many extant variants of the Traffic Conflicts Technique.
