Analysis of Social Equity in Congestion Pricing

Abstract:

In both thecretical and practical studies,models are constructed to analyze the inequity impact to different travelers from congestion pricing.It is assumed that value of time of travelers follows continuous distribution.In an example network,the equilibrium behavior of travelers in choosing travel mode and route is established.Then the variation of travel mode,travel route and travel cost after congestion pricing is investigated,and it is found that travel time and travel cost decrease after congestion pricing for the majority of travelers.Specifically,most bus passengers and drivers with high VOT benefit from congestion pricing,but few drivers with lower VOT suffer from congestion pricing.

Key words:congestion pricing; equity; value of time; traffic demand
