An Inexact Transportation Planning Model for Nonpoint Source Traffic Pollution Control

摘要

This study presents an interval programming model for traffic system nonpoint source(NPS) pollution control through odd-even restrictions on private vehicles policy underuncertainties. This restriction policy will result in enormous economic costs of publictransportation system especially in peak hours. To reduce the cost, tradeoffs can beemployed to deal with the bus departure frequency programs. We develop animproved method to effectively quantify the relationship among costs, execution timeof the restriction policy and the traffic environment quality by considering theuncertainties of traffic system. The results indicate that the efficiency of the programis significantly influenced by automobile ownership, the execution time of the policy,and level of emission limits of pollutants. Besides, the program can be easily extendedby integrating all bus routes for vehicle emissions management.
