Abstract
Road traffic safety is an important issue and should be given utmost priority by traffic engineers. This research aims to proactively evaluate safety for two un-signalized T-intersections along the western frontier of India with varying driving environment under mixed traffic condition using surrogate safety measure, Post Encroachment Time (PET). PET for different vehicle category as per approach leg was extracted. The Generalized Extreme Value (GEV) was found to be the best fitted distribution for explaining the temporal variations observed in PET values and was further extended to estimate crash probability. It was observed that driving environment has a prominent effect on crash probability. Improved driving environment reduced crash probability at the intersection. Results indicated minor approach road users comparatively have more crash probability to major approach road users. Median to be introduced at undivided intersection to enhance the driving environment and speed breakers, sign board installation is suggested at both the intersections.
