Study on Network Performance Evaluation Modeling under Congestion Pricing

Evaluation on implementing congestion pricing policy includes two sides: one is evaluation concentrated on the public policy economy environment and the technical feasibility of the pricing mode;the other side focuses on evaluating the network performance inside and outside the pricing areas under the congestion pricing.Both evaluations are important for traffic management decision.This paper's research focuses on the latter.Based on the traffic network analysis theory,this paper models the network performance changing under congestion pricing and presents some evaluation indexes.A simple numerical computational case study demonstrates the reasonability of the evaluation model and algorithm,which also indicates the network traffic pattern transforming mechanism inside and outside the pricing areas under congestion pricing.
