Facing the increasingly worse vehicle emission problem, the development of a quantitative and dynamic traffic emission model is becoming a premise for evaluating and implementing various emission control strategies. This paper is intended to develop a novel approach for the dynamic estimation and display of emissions for urban road networks. The paper first investigates the relationship between the traffic flow data and vehicle emissions by using an approach based on the concept of Vehicle Specific Power (VSP). After establishing three basic databases: VSP-Bin distribution database, VSP-Bin based emission rate database, and the vehicle type distribution database, a quantitative and dynamic vehicle emission model is developed. Furthermore, creating a dynamic display system of emissions based on traffic flow data is accomplished by incorporating the emission model onto the ArcGIS platform. Finally, it uses a case study to analyze the variations of mobile source emissions on the West 3rd Ring Road and its surrounding principal arterials in Beijing by using the real traffic flow data from RTMS and floating cars.
