On Efficiency of Identifying Hazardous Road Locations Using Accident Data

Abstract

It is necessary to understand the efficiency of selection criterion for identifying hazardous locations or blackspots adequately. In this paper, the degree to which the accident rate-and-number method is successful in identifying hazardous locations through periodic selections is examined. Simulation model developed for this purpose is applied. In the first part of this paper, the concept of identifying the hazardous locations and the measures of efficiency for site selection are described. The second part is devoted to the development of the simulation model. Finally, the performance of some feasible procedures through periodic selections using accident data is discussed.
