Traffic Conflict Studies

Traffic conflicts are interactions between two or more vehicles or road users when one or more vehicles or road users take evasive action, such as breaking or weaving in order to avoid a collision. Engineers use traffic conflicts as a supplement to traffic accident studies in estimating the traffic accident potential at an intersection or other location. Traffic conflicts are useful because the study results are often available much sooner than the results of traffic accident studies, when several years’ data may be needed. Traffic conflict studies can also provide much more detailed information than traffic accident studies. However, conducting traffic conflict studies is not simple. When performed improperly, they may provide misleading information. Traffic conflict studies require a relatively small investment of time and other resources and they require no special equipment. Trained observers watch traffic and note on a form when a conflict occurs. Observers usually require a week or less of training. This chapter describes how traffic conflict studies are very useful in determining the types of safety problems that exist at an particular location.
