| Abstract | Induced exposure models postulate a structure for accident data which permits the estimation of two factors: exposure and proneness. Since information on exposure is needed in order to assess the accident risk of different driver, vehicle, and environmental situations and since reliable exposure data is expensive to collect, induced exposure models hold the promise of a rich exposure data source which is perfectly matched to the accident data to be analyzed. This paper assesses the validity of the postulated structure of one induced exposure model: the Koornstra Model. The Koornstra Model was chosen for analysis and testing because it appeared to have the most potential for usefulness based on : a) previously reported favorable results (in limited testing); b) universal applicability; c) damaging criticism of certain other models; and d) a rich and well posed model structure. This paper analyses and tests the Koornstra Model from three different points of view: 1) Is it based on reasonable assumptions? 2) Does the model provide a significantly better fit to accident data than a simpler model which does not permit exposure or proneness to be estimated? 3) How do the exposure estimates provided by the model compare with those from externally collected data? |
