Development and application of urban high temporal-spatial resolution vehicle emission inventory model and decision support system
Résumé
This paper reports the development and application of urban high temporal-spatial resolution vehicle emission inventory model and decision support system based on the current situation and actual demand of vehicle emission control in China. The system incorporates a user-friendly modular architecture that integrates vehicle emission model and decision support platform, and with scenario analysis and visualization capabilities. A bottom-up approach based on localized emission factors and actual on-road driving condition has been adopted to develop the system. As a case of application and evaluation, the emission reduction effect analysis of supposed low emission zone (LEZ) policy in Beijing (2012) has been conducted. In the system, the simulation principle of environmental benefits brought by the LEZ policy could be duplicated to other similar environmental policies. By modifying configuration values or input data variables flexibly, the efficacy of separate or joint policy could be evaluated and graphical displayed quantificationally.
