More than 30% of all vehicle crashes in the United States occur at intersections; these crashes result in nearly 9,000 annual fatalities, or approximately 25% of all traffic fatalities. Moreover, these crashes lead to approximately 1.5 million injuri

In conditions of poor weather and restricted visibility, it is necessary that emergency vehicles (e.g., police, ambulance, snowplows) are still able to operate and respond to critical events in the road environment. This report presents the result of

The Intelligent Transportation Institute at the University of Minnesota is developing a Cooperative Intersection Collision Avoidance System - Stop Sign Assist (CICAS-SSA) for rural intersections as an alternative to signalized intersections. When dep

Detailed crash analyses indicate that poor gap selection, rather than stop sign violation, is the primary causal factor in crashes at rural, unsignalized intersections. To determine under what conditions the gap selection process fails, a transportab

We are developing an "intersection decision support" (IDS) system to assist drivers with decision-making at unsignalized rural intersections. When deployed, the system provides to a driver stopped at a minor road, information related to the safety of

Metro transit and the Minnesota DOT cooperatively operate a BRT-like system throughout the Twin Cities, Minnesota, metropolitan area. During peak congestion periods, buses operate on specially designated road shoulders (albeit at speeds significantly

We present a systematic method for quantifying the dynamic performance of differential GPS, and in particular the Novatel RT-20 DGPS unit, for determining a vehicle's lateral position in a highway lane. Image processing is used. Novatel's RT-20 Doubl

Manufacturers of automotive radar typically use narrow beam angles to minimize the number of detected objects (traffic signs, guard rails, etc.) which ought not to pose a threat to the host vehicle. Although narrow beam angles are sufficient for some

We describe the results from a series of experiments using the "virtual bumper" collision avoidance algorithm implemented on a Navistar International tractor cab. The virtual bumper combines longitudinal and lateral collision avoidance capabilities t
