Title: Exploring Pedestrian Temporal and Spatial Critical Gaps at Uncontrolled Midblock Crossings in India
Abstract: This paper aims to explore pedestrian temporal and spatial gap acceptance at uncontrolled midblock street crossings in a low priority environment, where vehicles do not yield to pedestrians and pedestrians have to choose safe gap on their own. The priorities in India are mainly due to perceived situations by pedestrians. Such conditions create more complex interaction between pedestrians and vehicles. Temporal and spatial critical gaps are estimated using both deterministic as well as probabilistic approaches. Field data were collected at two uncontrolled marked midblock street crossings using video cameras. Total of 1107 lag/gap observations were extracted and analyzed. The methods used for critical gap analysis resulted in significantly different results from widely accepted values of the highway capacity manual. The insights from this study can be used for supplementing the Highway Capacity Manual (HCM) analytical procedures; and to develop a methodology for the traffic of developing world where pedestrians are not given priority and hence have to choose safe gap on their own.
