TREDIS is rapidly expanding as the most widely used economic impact analysis system for transportation projects.  We've now had TREDIS applications in 32 US states and 7 Canadian provinces. (See list below.) 

If your state or province is not yet listed, then contact us so that a TREDIS model can also be developed for your area. If you'd like more information on any of the prior applications, check out our growing collection of case studies, or contact TREDIS staff for more details.
