This paper documents the development of a geographic information system (GIS) based system to support evaluation of transportation policies related to air quality planning--specifically with respect to carbon monoxide (CO) concentrations. The system provides a mechanism to relate the travel demand modeling process with air quality analysis. A case study of the Las Vegas valley demonstrates the development and application of the system. Since this area has been designated by the Environmental Protection Agency to be in non-attainment of the National Ambient Air Quality Standards for CO, a State Implementation Plan (SIP) must be developed to identify a plan for attaining conformity with those standards. Transportation sources of emissions account for a vast majority of the CO emissions in the Las Vegas valley. Thus, the development of a SIP requires explicit consideration of travel demand, vehicular emissions, and dispersion models. This paper describes the linking of tools and models required for this purpose. The system facilitates linking these models and thus minimizes duplication of resources, especially pertaining to data requirements. Due to the powerful capabilities afforded by a GIS to manage, manipulate, analyze, and display spatial data and due to the spatial nature of data required to support the analysis and modeling processes described here, a GIS environment was a logical choice for developing the model linkages. The system permits evaluation of the impact or effectiveness of policies ranging from land use planning/zoning alternatives to travel demand management strategies on CO concentrations in the valley. Menu driven interfaces are developed to enhance the ease of use of the system. The paper also addresses technological problems and institutional issues encountered during the development of the system.

Additional support was provided by the Puget Sound Regional Council and King County, Washington.
