Abstract
This paper aims to develop an environmental evaluation system by integrating traffic simulator and regional atmospheric simulator in order to analyze the effect of transportation policy for wide-area and to estimate traffic flow and atmospheric environment change, particularly focusing on SPM. Traffic characteristics and mol-side-land-use information on the region, traffic signal were inputted in traffic microscopic simulation “Paramics”. Especially we developed a new model for modifying OD matrix to improve the accuracy of traffic flow, and a PM emission model to calculate PM volume in high-resolute time scale by considering vehicle behavior and geographical characteristics.
