摘要：Safe and efficient movement of people and goods is stated as the goal of transportation. But accident statistics show that number of accidents is increasing in developing countries. In India, majority of the accidents are found to take place on highways passing through rural areas. Rural highways are characterized by a low traffic volume and hence, speed of the vehicles is mainly controlled by the geometry. Estimating the number of crashes that may result for a given highway design is a matter of great interest to the highway engineering community. A road crash prediction model can estimate the expected number of crashes that could result from a given highway design. The output of the work is to analyze the accident patterns on the horizontal curves on selected three road stretches, to develop an accident prediction model and to develop some evaluation criteria based on that. From the study it is found that the geometric parameters have significant influence on crashes on curves. An increase in the degree of curvature, level difference at midcurve, width of road showed an increase in the number of crashes. The skid number also showed a significant effect on crashes. The evaluation criteria was developed based on EPDO values to identify the low risk, medium risk, high risk curves.
