Samenvatting
An analysis of the traffic conflicts data collecte dur-ing 1980 for five unsignalized intersections using the PostEncroachment Time (PET Technique is presented. mhe PET isan operational tool for engineers responsible for determin-ing the need and consequences of changing roadway geometrics and for traffic control systems. With respect totesting the validity of the PET as an indicator of trafficsafety problems at unsignalized intersections, the dataanalyzed provided mixed results due,in large parts, to thesize of the data base.
