Abstract
Alleviating urban traffic problems is one of the most practical approaches to
improving urban air quality. A system dynamics approach was used to

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
