The Utah Unified Plan is a comprehensive list of proposed transportation investment projects that are recommended for implementation over the next 30 years. It is compiled by Utah DOT and the state’s Metropolitan Planning Organizations. Since the funding for this plan was uncertain, the Utah Mobility Coalition, a business organization, commissioned an analysis using TREDIS to show the statewide economic growth impacts of alternative funding levels for implementation of the plan.
The study assessed the economic benefits and impacts on jobs, household income, business output and Gross Domestic Product associated with three different funding levels. The study also estimated the public return on investment (ROI) for transportation dollars spent on the plan, and quantified Utah's overall economic dependence on different passenger and freight modes of transportation.
To accomplish this, the analysis entailed evaluation of how alternative revenue and expenditure scenarios would affect Unified Plan implementation, and how alternative implementation levels will ultimately affect travel times, vehicle operating costs, freight logistics, market access and productivity improvements for Utah businesses in various regions of the state. Impacts on safety and air quality environmental improvements were also analyzed.
