Movement Patterns of Pedestrians and Cyclists at Signalized Segregated Crosswalks: A Case Study in Nanjing, China

Interactions and conflicts between vulnerable road users, mainly pedestrians and cyclists, are frequently observed on crosswalks, especially in urban areas with relatively high traffic volume. To alleviate the potential safety risks, one possible measure is to adopt the segregated crosswalk to provide separate crossing space for pedestrians and cyclists. However, the crossing behaviours of pedestrians and cyclists at segregated crosswalks have rarely been investigated. To fill the gap, this study aims to investigate the movement patterns of pedestrians and cyclists at signalized segregated crosswalks. Field observations and data collection are conducted at a typical intersection with segregated crosswalks in Nanjing CBD, China. In total, trajectory data of 659 pedestrians and 1,212 (e-)cyclists is collected and analysed. The route choice and crossing speed of pedestrians and cyclists are explored, and multiple influencing factors are analysed. The research findings indicate that road users, especially cyclists, in the minor direction violate the segregation rule more frequently compared to road users in the major direction. It is recommended to adopt the segregated crosswalks mainly for unidirectional pedestrian and cyclist flow.
