By offering a flexible TREDIS subscription, you select how long you need access to this advanced web-based system.  Subscriptions are offered for periods as short as three (3) months and may extend to multiple years as needed. And all TREDIS subscriptions include comprehensive support and no-charge updates as new versions of TREDIS are made available. 

Partner Program

Get more value from TREDIS by leveraging your subscription with DOT, MPO, university, and consulting partners for long range planning and scenario analyses.

The program was designed to enable State DOTs the chance to offer partners to access to their TREDIS subscription for a nominal fee. Since TREDIS provides full user access controls, the DOT and MPOs can either share their analyses or keep them separate and private, as desired. For more information now, call or email us and we will fill you in on how this can also work in your state.

Use TREDIS in classroom settings to teach transportation economic impact and benefit-cost analysis.  The TREDIS University Program offers unversity faculty and students access to TREDIS as a classroom teaching tool at no cost.  It includes:
