Abstract

Field studies and analyses of observation of traffic conflicts at intersections are described. The field studies covered more than 24 sites and used 17 trained observers who applied a number of alternative operational definitions of traffic conflicts. The definitions that provide the best reliability, repeatability, and and practicality are recommended. Initial estimates obtained of expected conflict rates as a function of type of intersection are also given.
