Texas Urban Triangle: Pilot Study to Implement a Spatial Decision Support System (SDSS) for Sustainable Mobility

This project addressed sustainable transportation in the Texas Urban Triangle (TUT) by conducting a pilot project at the county scale. The project tested and developed the multi-attribute Spatial Decision Support System (SDSS) developed in 2009 under a previous UTCM project (TRID Online Accession #01324956), in order to determine the most suitable locations for transportation infrastructure networks, including high-speed rail. The research team selected a key county in the Austin-San Antonio segment of the Interstate 35 corridor. The project mapped, using the eight different strategic economic, social, and environmental factors in the model, the most and least suitable locations for the new transportation infrastructure. It is expected that the outputs of the model be used by TUT metropolitan planning organization's (MPO's), Texas Department of Transportation (TXDOT), metropolitan visioning groups, high-speed rail providers, and similar entities.
