Lesson Background HTML
The Minnesota Traveler Information Guidance and Emergency Routing (TIGER) project was one of a small number of projects selected for National Evaluation from the population of ITS Integration Program projects. The projects selected for National Evaluation received funding from the Federal Highway Administration's (FHWA) ITS Deployment Program for the purpose of accelerating the integration of new and existing ITS projects. The Minnesota TIGER project sought to improve travel time, travel time reliability, and safety through the deployment and integration of traffic monitoring, advanced communication, and traveler information components along the Interstate-94 (I-94)/Highway 10 corridor. The corridor is about 50-miles and connects the Twin Cities region with the St. Cloud region, each of which are experiencing rapid growth and increasing demand on I-94 and Highway 10. The corridor, consisting of urban, suburban and rural components, serves as a daily commuter route as well as the primary emergency evacuation route for the Twin Cities. (Of relevance to the evacuation route function of the corridor is the Monticello Nuclear Power Plant, which is located between I-94 and Highway 10 outside Monticello.)
The Minnesota DOT (Mn/DOT) launched the Tiger project in response to the increased demand on the corridor. The project sought to improve daily traffic conditions as well as develop systems for emergency routing for evacuations by applying metropolitan ITS components. For example, the project installed surveillance technologies including closed circuit television (CCTV), and loop and radar-based traffic detection, which were integrated with the regional Traffic Management Center (TMC). Other deployments included traffic signal coordination for the purpose of adding capacity on Highway 10 in the event of an incident on I-94, and enhanced communication and coordination between highway patrol personnel, transportation staff and emergency responders. An independent evaluation reported on the mobility and safety impacts on the corridor resulting from the TIGER deployments.
