Tradable credit scheme on mode choice equilibrium with park and ride facility

Based on a linear mono centric city, with the explicit consideration of user heterogeneity, i.e., each commuter has a different value of time (VOT), this paper investigates the optimal Park and Ride (P&R) location along the subway in a mode choice equilibrium model. On the basis of the model, we further examine the impact of the Tradable Credit Scheme (TCS) on the mode choice equilibrium. Numerical results shows that TCS could effectively attract some commuters divert from auto-mode to P&R mode, and the amount of commuters driving all the way continuously descends with the increase of the credit price. Furthermore, we find that there is an optimal price to ensure the total system cost keeps the minimum.
