Modeling Analysis of the Sustainable Development of Urban Traffic Based on Vehicle Policy

Abstract

AbstractA system dynamics (SD) model of the sustainable development of urban transport is built with vehicle development policy considered as the regulating factor. Moreover, an empirical study is conducted using SD and integrating environmental factors. Results show that (1) policy intervention influences the indicators of vehicle possession, gross domestic production, total population, and pollution index of NO2; and (2) strict restrictions on vehicles can effectively relieve traffic congestion, reduce the percentage of vehicle travel and trips, and urge people to shift from private to public transport. Policy intervention also improves the service level of public transport. The negative effect of urban transport development on the environment can be reduced. A restriction policy on vehicle possession should be implemented. Moreover, research, development, and promotion of effective energy-saving measures and emission-reducing technologies are needed to reduce energy consumption and emissions from vehicles.
