Providing the Aproperiate Statistical Model due to Safety Index in Pedestrians Crash Prediction (Case study: The Number of Intersections in Tehran)

A considerable amount of accidents occur at signalized and urban intersections which are the intensive crash places. Therefore in this paper appropriate models that could specify safety indicators have been indicated with existing information by characterized dependant and independant variables for 16 signalized intersections. The results of sensitivity analysis show that the maximum sensitivity of pedestrian crashes is related to bus stop which nears to intersection and increases 21.07 % of pedestrian crashes. This happens because more pedestrians are crossing stations.Discrete turn reduces 20.34% of pedestrian crashes at intersections.
