Gateway Traveler Information System Site Policies

The Illinois Department of Transportation (IDOT) has implemented a revised policy and registration procedure for users wanting access to the Gateway Traveler Information System (GTIS) real-time traffic information which includes travel time and congestion data, camera image snapshots, dynamic message sign legend information, lane closure and construction information, incident data, and weather station data.

Traffic information is currently available without charge to individuals, organizations and companies via periodic downloads of data in XML format and JPEG images — Please note that IDOT reserves the right to discontinue this service for any reason without explanation.

Individuals, organizations and companies who wish to obtain traffic information must apply for these services by completing our Traffic Information Access/Reuse Registration form:

Traffic Information Access/Reuse Registration

It is very important to read and understand the provisions contained in both the registration form above and the IDOT Traffic Information Access/Reuse Policy.

Subscribers are required to review and/or update their account information at least once a year:

  1. Sign in.
  2. Select Update Account from the admin menu.
  3. Make any necessary changes and press the Update Account button (even if there are no changes). Or if you no longer need the account, pressing the Delete Account button will immediately remove it from our system.

We want this process to be convenient and beneficial to our users, and we look forward to serving your current and future traffic information needs.
