MODELING THE TRAFFIC-SAFETY SYSTEM

A MODEL IS NEEDED THAT CAN INTERRELATE THE FULL RANGE OF RELEVANT TRAFFIC-SAFETY ACTIVITIES AND PREDICT THEIR CONSEQUENCES IN TERMS OF COLLISIONS, DEATHS, INJURIES, AND PROPERTY DAMAGE. THIS PAPER DEVELOPS A CONCEPTUAL FRAMEWORK FOR A TRAFFIC-SAFETY MODEL AND IDENTIFIES RESEARCH NEEDED TO MAKE THIS FRAMEWORK INTO AN OPERATIONAL MODEL. A TRAFFIC ACCIDENT MAY USEFULLY BE CONCEPTUALIZED AS PROGRESSING THROUGH A SERIES OF PHASES, EACH A PROCESS OF INTERACTION AMONG MANY FACTORS ASSOCIATED WITH THE DRIVER, THE VEHICLE, THE ENVIRONMENT IN AND OUTSIDE THE VEHICLE, AND CHANCE. ACCORDINGLY, THE MODEL IS FORMULATED AS A CHAIN OF PHASES, WHERE EACH PHASE HAS ALTERNATIVE POSSIBLE OUTCOMES - CALLED SITUATIONS - WHICH ARE PHYSICALLY OBSERVABLE AND OPERATIONALLY MEANINGFUL. THESE SITUATIONS HAVE CLEAR AND APPARENT RELATIONS TO ACCIDENT LIKELIHOOD OR SEVERITY; REVEAL AT WHAT POINTS AND IN WHAT WAYS THE ACCIDENT CHAIN MAY BE FRUSTRATED; AND CAN BE MEASURED AND EXPRESSED AS INDICES OF PERFORMANCE. /AUTHOR/
