Abstract:This project developed a GIS-based Spatial Decision Support System to help local, metropolitan, and state
jurisdictions and authorities in Texas understand the implications of transportation planning and
investment decisions, and plan appropriately for the future. It provides an easily accessible, graphically
represented, interactive database on infrastructural, demographic, environmental, agricultural, economic,
hazard, and land use factors that affect transportation corridor location decisions. Specifically, the project
team created an Internet-based spatial decision support system that will allow users to identify and
visualize geographically those critical issues related to locating single mode or multi-modal surface
transportation corridors for freight and passengers. Decision makers will be able to test multiple attributes
in the decision making model to compare multiple transportation corridor scenarios for optimal mobility
based on the decision parameters developed in the model. Jurisdictions and transportation authorities will
use this tool to guide future decisions on transportation and its impacts on urban growth in a sustainable
manner so that the need for economic development is balanced with environmental protection and human
health, safety, and welfare. The system also helps address important research questions related to where
future growth will occur in the Texas Urban Triangle, and at what scale, densities, and uses and to study
selected impacts of this growth. Finally, the SDSS demonstrates the usefulness of WebGIS in facilitating
sustainable transportation planning, policy making and investment decisions.
