A Spatial Model Based on Dynamic Rail Commuter Equilibrium in a Monocentric City

This paper presents a spatial model of rail commuter congestion in a monocentric city to investigate the congestion level on each location along the rail line. A dynamic rail commuter model is formulated to capture the variable crowding environment properties in peak period. Unlike most of the former research studies on monocentric city, we found that not only the total demand of each location will affect the travel cost, but the distribution of the population along the corridor should not be ignored as well. Furthermore, given the functional relations between the total demand and travel cost, a novel spatial equilibrium is established on the equilibrium travel cost. The main contribution of this work is given the general spatial equilibrium a dynamic fundament.
