THE MICROECONOMIC ANALYSIS OF THE EXTERNAL COSTS OF ROAD ACCIDENTS

A disaggregated model of the marginal external costs of road accidents imposed by different road users is developed. The model explicitly sp ecifies the adjustment of road users to increases in accident risks im posed by additional road use and is used to estimate the marginal exte rnal costs of road accidents. The results, under certain assumptions, are up to 50% less than those obtained using the methods of previous s tudies. However, the adjustment to the increased risks of accidents le ads to other costs, such as congestion and reduced pedestrian mobility . These costs should be included in a comprehensive analysis.
