Research on the revenue allocation strategies of congestion charge in a two-modal transport system

A competitive transportation system with a mass transit (subway) parallel to a road way constrained by a bottleneck is considered. All travelers are divided into two groups. All travelers of one group have cars, and the other group have no cars. Travelers with cars can choose driving car or taking the subway, and travelers without cars can only take the subway. Under the optimal charging of bottleneck road, this paper analyzes five strategies to return the congestion charge revenue for public transportation travelers considering the body congestion cost of carriage in subway, and introduces the distribution proportion of the congestion charge revenue which takes into account the equity of individual travel cost and the efficiency of road traffic system, and verifies the theoretical results through numerical examples.
