TREDIS assesses economic impacts, benefits and costs of transportation policies, plans and projects from alternative perspectives. It is used throughout the US and Canada ... and now also in Australia.

Sophisticated ... not complicated!    With the introduction of TREDIS 4.0, transportation planners and policy leaders get access to an enhanced decision support system that makes it easy to incorporate economic factors into transportation planning.  The system provides users with an intelligent, guided approach matched to transportation planning stages. And it provides reports on financial, tax, economic impact, benefit-cost, ROI and performance reports that are tailored to target audiences.
