Role of Systems Analysis in Traffic Safety

To reduce the losses incurred in motor vehicle operations, all of the factors contributing to the creation of the accident event must be considered. A systematic itemization of these factors indicates that perhaps several hundred environmental, vehicle, and driver factors affect traffic safety. In order to identify the changes which must be made in the interests of improved traffic safety, the techniques of systems analysis can be applied to select those programs which will provide the greatest improvement in traffic safety for the effort expended, whether it be in the area of vehicle improvements, roadway improvements, or driver improvements.
