GIS-INTEGRATED TRAFFIC INPUT MODELS FOR MOBILE-SOURCE EMISSIONS ANALYSIS

The Environmental Protection Agency recently released the latest version of its mobile-sources emissions model, MOBILE6, its first major update to the MOBILE series since 1996. This model will soon become the required standard for air quality conformity analysis transportation conformity measure (TCM) effectiveness analysis. A brief review of the input requirements of the MOBILE6 emissions factor model is presented which is followed by a more detailed discussion of the traffic-related input needs of the model. In particular, the various issues involved in the modeling of vehicle registration distribution and the vehicle miles traveled (VMT) distribution, the methodology adopted, data acquisition and analysis, and the modeling results are discussed. The report also briefly describes the geographic information system (GIS)-based software application developed to facilitate TCM analysis. Some simple TCM scenarios that were analyzed as part of the study are also presented to better explain the application of the software to perform TCM analyses.
