Pedestrian flows and walking speed : a problem at signalized crosswalks

A recent fatal accident at a signalized crosswalk in Hong Kong highlighted the inability of the current design to account for high pedestrian flow volumes and emphasized the need for studies on walking speed. The effect of pedestrian flow volume on walking speed at signalized traffic intersections was studied using data obtained from an observational study in Hong Kong. The study revealed that the problem of high pedestrian flow volume and its effect on walking speed is a valid concern because it can result in significant differences between the design and the actual change interval required by a pedestrian.Department of Civil and Environmental Engineerin
