Title Congestion Road Pricing Policy for Heterogeneous Commuters: Static Analysis Approach
Author Chih-Peng Chu & Lih-Sheng Yeh
Summary   After Pigou opened the “door” of congestion road pricing in 1920, this economics tool plays as an importation method on travel demand management. Accompanied by the growth of economic activities and rise in household income, the increase in demand of travel is tremendous, especially the usages of private transportation modes. Under the constraints of supply, most of the metropolitans are having terrible traffic congestion problems. With the revolution and improvement of electronic technologies, the road congestion pricing theory seems to be feasible now. On the other hand, the theory of road pricing has switched its focus from first-best pricing (marginal cost pricing) to second best pricing and extended its analytical abilities to much realistic situations. However, most research adopted the assumption of homogeneity of demand characteristics to simplify their models. However, in real world the demand is heterogeneous. This article considers a congestion pricing model with two types of elastic-demands on a highway system and an alternative local road under three different policies. This article shows the traffic impacts on two types of travelers and welfare impacts of total society under these three different pricing policies. The proposed model and different polices are illustrated with numerical examples.
