摘要

Pedestrian deaths constitute to about 23% of the road deaths globally. Although several researchers have contributed to the pedestrian safety analysis, arriving at comprehensive solution requires an in-depth study. This is attributed to various complex factors involved at the pedestrian crossings, in a typical urban scenario. Pedestrian path for crossings mainly depends on the spontaneous interaction with the space available. This phenomenon is rather a psychological reaction of the pedestrian rather than aspects to safety and comfort. This work identifies the traffic conflict situations between pedestrian and vehicles in a typical urban scenario. A discrete model for the same is analysed for the urban scenario. For the work, three multilane intersections with high pedestrian volumes in the city of Bengaluru are used for the study. Patterns of travel both for pedestrian and vehicles are observed with videographic data. The lateral and longitudinal critical distances between pedestrian and vehicles are measured and calibrated using an open-source software ‘tracker’, for real life scenario. Statistical analysis and regression are undertaken to assess the pedestrian behaviour at the urban intersection crossings. The approach chosen is realistic and can be used for studies especially for intersections with heterogeneous traffic conditions.
