Proactive Approach for Pedestrian Safety Evaluation Using Choice Model for Unprotected Mid-Block Crossings under Mixed Traffic Conditions

When it comes to road traffic crashes, pedestrians are among the top road users at-risk, especially in developing countries with highly heterogeneous traffic. With a high percentage of pedestrian and bicyclist fatalities in India, most of these occur at mid-block locations, with a large percent related to road crossing. In order to address this issue, it is necessary to understand the nature of pedestrian crossing behavior, as well as pedestrian-vehicular interaction. Various modeling techniques were undertaken to identify factors contributing to driver yield behavior, which is a significant safety factor for pedestrians at unsignalized/mid-block crossings. Videographic data was collected in Delhi, Chandigarh, Mumbai, Surat and Ahmedabad to determine roadway width, and surveys were undertaken for pedestrian and vehicular flow at unprotected mid-block crossings. Choice models were calibrated and validated. An elasticity analysis showed that traffic gap size was the biggest determinant in pedestrian decision to safely cross the road.
