How Actual Impedance and Overall Experience Shape the Walking Catchment Area of Rail Transit Station: A General Walking Efforts Framework

The objective of this paper is to investigate the role of built environment (focusing on walking route characteristics) in determining the Walking Catchment Area (WCA) of rail transit station. In a proposed conceptual framework, two types of walking route attributes, Actual Walking Impedance and Overall Walking Experience determine the size of WCA by influencing General Waling Effort in distinct modes. Consequently, the Kishi's Logit PSM (KLP) model and OLS regression model are respectively applied to quantify the effects of different walking route attributes on WCA. In the KLP model, trade-offs are measured between walking distances and walking impedance based on transit users’ sated preferences data. The OLS regression attests that walking experience contributes in pedestrians’ underestimation/overestimation of perceived walking time, and thereby affects the size of WCA. With the improvement of some walking route characteristics, the before-and-after change is recognized in size of WCA.
