Experimental analysis of pedestrian behavior at different configurations of crosswalks at roundabout legs

Abstract

Walking has recently been one of the most popular forms of mobility proposed in many urban plans and in the new concept of sustainable mobility. This study investigated pedestrian behavior when crossing the legs of urban roundabouts. Pedestrian crossing behavior was analyzed using video recordings made at seven crosswalks located on urban roundabouts. To describe pedestrian behavior, crossing conditions (legal or illegal) and Kerb Delay were chosen. The data obtained from the video analysis were treated with CHAID analysis to determine the distribution of the parameters chosen as a function of features considered more conditioning. A path analysis was then performed to assess the influence of these features on the parameters defining pedestrian behavior. In order to encourage legal pedestrian behavior, the results of the present study suggest implementation of refuge islands at the legs of roundabouts. The research results can help refine the algorithms that define autonomous vehicle-pedestrian interactions.
