A method of subjectively recording traffic conflicts or near accidents has been developed by TRRL for identifying safety problems and evaluating countermeasures, primarily at road junctions. This paper states the established conflict definitions and describes in detail the method of collecting conflict data and the way in which the data are used by many local highway authorities. A training package for new observers is still under development and a brief synopsis of the contents of the training manual is included. The results of validation studies relating conflict counts to recorded injury accidents have been encouraging and a summary is given. Recently completed experiments in which conflict counts were compared with results from other subjective assessment methods at road junctions have demonstrated that these methods do not provide an acceptable alternative to conflict studies.
