Transportation Economic Development Impact System (TREDIS)
By: Scott Moore
The Transportation Economic Development Impact System (TREDIS), is a product developed by the Economic Development Research Group, Inc (EDR). It is an integrated framework for transportation planning and project assessment – designed to cover a wide range of applications, from looking at benefit/cost impacts of a single transportation investment, to analyzing the macroeconomic impacts of alternative long-range plans.
It models passenger and freight travel across all modes, and it assesses costs, benefits, and impacts across a range of economic responses and societal perspectives. To integrate this range of features, TREDIS operates as four separate but interconnected modules:
- Travel Cost
- Market Access
- Economic Adjustment, and
- Benefit Cost
