The purpose of the project was to develop a method for collecting and analysing information about near accidents in road traffic. Two pilot studies were performed. In these a total of 75 subjects reported all near accidents over a two week period. Before each experimental period meetings were organized in order to inform the subjects about the project and its aim. Using several examples a clear precise definition of a near accident was presented. The definition reads as follows: a near accident is an event which could become an actual accident. During the course of driving something may happen suddenly, which could result in a collision with a third party or vice versa. This situation may necessitate sudden evasive action by persons involved such as braking, swerving or accelerating in order to avoid a collision. During the test periods the subjects completed structured notes on a daily basis and a questionnaire for each near accident. A photographic record of the location of the near accident was made and, in most cases, the subject concerned was interviewed. The success of the pilot study was judged by the following points: (a) the number of reported near accidents, (b) the quality of details in the reported information, and (C) the relation between reported near accidents and accident statistics. The results show that although the subjects had diligently filled in the forms, important information about the traffic environment was missing. The photographic records seemed to provide this information. /TRRL/
