The Study of Pedestrian Accessibility to Rail Transit Stations based on KLP Model

摘要

In order to study the travel range of the pedestrian choice of rail transit, this paper analyzed factors influencing the choice of walking access mode, by conducting simulated experiments and questionnaires investigation. Based on Kishi's Logit Price Sensitivity Meter (KLP) model, a method for calculating the distance and time threshold of pedestrians’ access to urban rail stations was presented. It also drew some conclusions that the standard walking access distance is 472 meters and the maximum value is 862 meters, from the point of pedestrians’ willingness. Furthermore, the ideal access time and maximum acceptable time is 8.1minutes by 50th percentile and 16.3minutes by 85th percentile, respectively. The paper made a comparative analysis about the distribution features of pedestrian distance and time acceptability and the differences between the feel accuracy of time and distance for individuals. In addition, these differences were further used to revise the space- time threshold values.
