 What is TREDIS?

TREDIS® calculates the economic impacts, benefits and costs of proposed projects, programs and policies. It is a comprehensive decision support system that spans economic impact analysis, benefit-cost analysis, and financial analysis, as well as freight and trade impact analysis. It is the only system applicable for all modes – covering passenger and freight transport via aviation, marine and rail modes, as well as truck, car, bus, bicycle, and pedestrian travel.

Use TREDIS for deep analysis of a single project or simultaneous comparison of many projects. Impacts may be viewed at local, regional, state or national levels.

What makes TREDIS special?

TREDIS is complete. It assesses impacts and benefits of capital investments, operations, maintenance, and financing for all modes and types of projects. It can show local and regional impacts in terms of changes in costs, productivity, equity, economic growth, energy use and emissions.

TREDIS employs a dynamic economic simulation. It calculates short- and long-term impacts of transportation changes, which can be viewed from the perspectives of different stakeholders, study areas and, time periods.

TREDIS is a U.S. cloud-based system. It enables simultaneous use by multiple agencies, organizations and staff members, with user-defined study areas and time periods. It links to client transportation and economic systems.

TREDIS leads the industry. It provides new visualization and analysis capabilities with unsurpassed customer support, documentation backed by published research, and transparency to trace and explain calculated results.

 What is TREDPLAN?

TREDPLANTM is a system for robust long-range planning that accounts for risk and uncertainty. It provides planners with a way to view the transportation, energy, workforce and economic implications of likely or possible future shifts in global trade, technology and the environment. It enables “volatility/risk” analytics, making it possible to optimize results by allowing for (or adapting to) possible futures. This enhances the robustness (and reduces the fragility) of transportation plans, energy plans and economic development strategies. TREDPLAN also benchmarks implications for your competitors and surrounding regions, enabling analysis of vulnerabilities and opportunities. There are three versions of TREDPLAN: Regions, Economy and Ports.

TREDPLAN Scenario Impacts

TREDPLAN Scenario Impacts


  • Optimize infrastructure investment – develop new capacity to allow for demand shifts, risks and uncertainties. see examples Arrow Right

  • Develop “right-sizing” strategies – repurpose or resize existing facilities to align with future needs. see examples Arrow Right

  • Minimize failure risk – assess alternative futures and consequences of under- or over-investment. see examples Arrow Right

  • Strategy – assess how shifts in technology, trade & policy will affect your competitive position and create new opportunities. see examples Arrow Right

What makes TREDPLAN special?

TREDPLAN builds on a cloud-based megadata platform. We have over 3 TB of detailed data on economic, trade, and freight trends – past, present and projected future –covering all counties in the US and countries or regions of the world, with details for hundreds of industries and commodities, as well as occupations and population groups. We leverage this to show how future change can affect future demand for travel, energy and occupations.

TREDPLAN compares the implications for alternative scenarios. We have a library of future forecasts, including from post-COVID optimistic and pessimistic scenarios in Moody’s Analytics macro model, as well as projections for implications of shifts trade and technology, and disruptive changes in weather and seismic events. Since TREDPLAN is cloud-based, we can directly distribute analytics for other scenarios as requested.

TREDIPLAN has a powerful analytic engine. It finds other areas (or ports) with similar profiles in terms of product, purchasing and shipment patterns, that may be seen as competitors or benchmarking comparators. TREDPLAN compares current and projected future trends to identify your relative vulnerabilities and opportunities.

TREDPLAN enables smart public investment. It provides needed insight for optimizing infrastructure investments, programs and policies.

The TREDIS Team is dedicated to helping you successfully analyze the impact of your transportation infrastructure investments.
