Abstract

Application of system dynamics with GIS for assessing traffic emission management policy L. Chen and W.-L. Yang Department of Water Resources & Environmental Engineering, Tamkang University, Tam-Shui, Taipei, Taiwan Abstract A system used for assessing impact from traffic management policy on urban air quality was developed and demonstrated. The system consists of two models, the trip analysis model and traffic emission assessment model. The trip analysis model is used to screen probable trip routes. Three submodels are included in the traffic emission assessment model. There is first, the Logit submodel for preference analysis to derive users' mode selection, second the traffic flow submodel for traffic speed analysis; and third, the traffic emission submodel for calculation of NO% and HC emissions of all modes under various traffic conditions. A Taipei case study was performed by the application of the system. Three traffic management policies, the carpool, rescheduling bus f
