Walk or wait? An empirical analysis of street crossing decisions
研究行人在信号交叉口如何根据车流间隙决定是否过街，用参数和非参数方法估计行人临界间隙的分布，基于新德里三个交叉口的实地数据模拟交通灯变化对过街行为的影响。
Abstract We examine the behaviour of pedestrians wishing to cross a stream of traffic at signalized intersections. We model each pedestrian as making a discrete crossing choice by comparing the gaps between vehicles in traffic to an individual‐specific ‘critical gap’ that characterizes the individual's minimal acceptable gap. We propose both parametric and nonparametric approaches to estimate the distribution of critical gaps in the population of pedestrians. To estimate the model, we gather field data on crossing decisions and vehicle flows at three intersections in New Delhi. The estimates provide information about heterogeneity in critical gaps across pedestrians and intersections, and permit simulation of the effect of changes in traffic light sequences on pedestrian crossing behaviour and waiting times.
