Abstract

Alleviating urban traffic problems is one of the most practical approaches to improving urban air quality. A system dynamics approach was used to integrate three sub-models to evaluate the impact of urban NO% and HC emissions from traffic management policies. The three sub-models are the Logit model for estimating the fleet composition from user's preference, the traffic flow model for estimating vehicular speed and the traffic emission model for estimating the individual vehicular emissions from scooters, cars and buses. The application of the system to evaluate the impact of traffic management policies to Taipei City's traffic and air quality was demonstrated. Five policies, namely the exclusive bus lane, bus fare compensatio
