New TREDIS Webinar, September 23rd: Electricity and Fuel Production Emissions, Local Air Quality, and Congestion Impacts

In this session, we’ll walk through new features that enhance how you evaluate the environmental impacts of transportation investments. You’ll see how TREDIS now provides a more comprehensive view of emissions by accounting for upstream fuel production, regional differences in pollutant impacts, and the effects of congestion on local pollutant emissions.

New Reliability Variables and Data Export Functions

This session covered the new reliability variables released at the end of February that enable easier input of both sketch-level reliability scenarios and post-processed travel demand model results. We also highlighted the new detailed results exports, which allow you to bulk export most TREDIS reports for single or multiple projects, and how this capability becomes relevant in the context of our adjusted data retention policy and upcoming changes for economic data availability before 2022 contract years. This webinar aired on May 19th, 2026.

Using Freight Data for Economic Evaluation of Freight and Supply Chains
		This session discussed freight datasets and how they can be used to with TREDIS to analyze freight infrastructure and supply chains. We shared a comparison of available freight datasets: spatial considerations, strengths, and applications; what we can learn from the base freight data and forecasts; how freight data can be leveraged for scenario development and economic analysis; detailed walk-through existing case studies; and the overall need for freight infrastructure investment.

Using TREDIS MBCA for Grant Applications
		During this one-hour demonstration, we highlighted some key elements of the latest RAISE grant, due April 14th, walked through the process of performing a Benefit-Cost Analysis of a transportation project using the TREDIS Multi-modal Benefit-Cost tool, covered how to develop scenarios, provideed guidance on interpreting results, and highlighted the ways users can perform reality checks to ensure accurate results. We also covered the use of the Federal Grant Review feature to share your analysis with US DOT grant reviewers. The live demonstration covered the input requirements and the process of completing a project analysis. Presentation Slides

Applications in Economics in Transportation Planning and Prioritization
		Watch as three presenters from state DOTs and MPOs shared their experiences incorporating economic impact and economic benefit analysis into their project prioritization and program planning processes. Presentation Slides
Adjustments to Transportation Planning for a Post Pandemic World
		This webinar provides information on emerging changes in long-term transportation trends and expectations that will likely follow after the pandemic, and it discussed what this can mean for transportation investment planning, funding and prioritization. The webinar identified “levers” in travel demand models and in the TREDIS economic framework that can be used to explore scenarios for long-term future change, and assess their economic implications for decision-making. Presentation Slides
Fundamentals of Using TREDIS
		This webinar showcased a step-by-step demonstration of how to perform an Economic Impact and Benefit Cost Analysis of a transportation project using the TREDIS system. It focused on the basic operations of the TREDIS web-based system, walking through a simple transportation project. It highlighted the basic input requirements and demonstrated new features. TREDIS staff provided guidance on interpreting results, and highlighted the role of economic impact analyses as well as benefit-cost and fiscal impact analyses for evaluating and prioritizing transportation projects.
