The Intelligent Transportation Systems (ITS) Section of the Minnesota Department of Transportation (Mn/DOT) Office of Traffic, Safety and Technology (OTST) performs research, demonstrations, and operational tests of ITS transportation solutions. The annual report of the Mn/DOT OTST ITS Section’s funded activities for the 2010 fiscal year describe the results of deployed and ongoing ITS projects.
The Cooperative Intersection Collision Avoidance Systems (CICAS) initiative determines the optimal combination of infrastructure and in-vehicle systems needed to address a full range of intersection crash problems. The CICAS initiative will integrate two types of intersection collision avoidance systems—infrastructure-based and vehicle-based. The present deployment warns drivers of unsafe gaps in traffic at rural thru-stop intersections. Other areas are being studied.
Deployment of CICAS systems will reduce fatalities and injuries at rural thru-stop intersections in addition to delaying or even eliminating the need for a traffic signal or other geometric improvement.
