Pedestrian traffic crashes have become a very common scenario on urban arterial roads because of rapid growth in developing countries like India. Due to high speed of vehicles and continuous flow of traffic, the crossing of pedestrians particularly at mid-block of an arterial road becomes concern issue of safety. The crossing behavior of pedestrian is governed by age, gender, vehicle speed, pedestrian’s speed, type of following vehicle, and gap acceptance. Microscopic analysis was carried out considering different parameters like age, gender, crossing pattern, pedestrian’s crossing speed, vehicle categories, vehicle speed, and vehicular gap which were extracted from videos. Gap acceptance is an indicative measure of risk-taking behavior of pedestrian while crossing the road. It was observed that female pedestrians having less risk-taking practice for crossing the carriageway are compared to male. Study also estimated critical gap using Raff’s method for different age group and gender and it was found to be less for young age group compared to middle and old age group pedestrian. Similarly, critical gap for female was observed to be more than that for males. For the study site, two types of crossing patterns were observed namely straight and oblique. Majority pedestrians were found to follow the straight pattern rather than the oblique pattern. The present study helps to understand the complex pedestrian road crossing behavior which can be useful for improving pedestrian safety measures at mid-block section and further planning of the facilities for pedestrians.
