Abstract

In the social force model, interpersonal forces are manifested as the space between moving subjects, which serves as a reference for the range of forces between the target and other subjects. Although numerous studies have investigated the spatial requirements of road users, validating these findings using large, real-world datasets remains challenging. This study focuses on "safe spaces" for pedestrians and e-bicyclists during street crossings, considering both psychological and safety needs. Drone-captured video data from three major intersections in Xi'an, China, is utilized to examine these safe spaces. The findings indicate that pedestrians maintain semi-circular safe spaces while e-bicyclists maintain semi-elliptical safe spaces when crossing the street. Moreover, as the speed increases, the safe space expands. However, the safe space does not increase with speed indefinitely. The size of the safe space fluctuates in a certain range when the speed increases to a certain level. It is worth mentioning that e-bicyclist require greater safety distances in the forward direction than in other directions and are more influenced by speed.
