The Illinois Department of Transportation (IDoT) in the US has signed Delcan to upgrade and maintain its Gateway traveller information system (TIS).

The Gateway TIS is an intelligent transportation system that collects and validates transportation-related data for the Gary-Chicago-Milwaukee (GCM) Corridor and provides information on traffic congestion, incidents and travel times for drivers.

Delcan will deliver traveller information website usability improvements, performance improvements and upgrades to the system software to further integrate new data sources as well as configuration updates.

The one-year contract has been awarded through the University of Illinois-Chicago.

The GCM Corridor contains 2,500 miles of roadway connecting the three cities and spans 16 counties in Illinois, Indiana and Wisconsin.
