| 摘要： | This study attempts to define a framework for comparing various modeling approaches that can be used to assess the impact of intelligent Transportation Systems (ITS) strategies on mobile source emissions. The study begins by reviewing the connection between transportation and air quality, and by reviewing methodologies that have been employed in literature on the impact of ITS on emissions. An analysis framework is developed that provides a platform for performing a comparative evaluation of various network modeling and emission modeling approaches in the context of air quality assessment of ITS strategies. Procedures and tools required to implement such a framework are then described in some detail. Two case studies are conducted on the Fort Worth network and Houston network using this framework. Carbon monoxide (CO), hydrocarbons, (HC), and oxides of nitrogen (NOx) estimates form the simulation runs are then discussed and analyzed. |
