Abstract:

This report summarizes the project activities and results of the Generation 2 (Gen2) Driver Assist System (DAS) used by the Minnesota Valley Transit Authority (MVTA) for bus shoulder operations. It provides warnings for lane departure, side collision, and forward collision. The Gen2 DAS is a GPS-based technology suite that provides lane position feedback to the driver via light emitting diode (LED) warning lights embedded in the dashboard, warning icons on a liquid crystal display (LCD) touch screen, and a vibrating seat. The Gen2 DAS has several modifications that distinguish it from the Gen1 DAS, including the elimination of the head-up display, virtual mirror, and steering feedback. Also, the Gen2 DAS uses lidar for front collision sensing and radar for side collision sensing, whereas the Gen1 DAS used lidar for both. MVTA’s primary goal for the Gen2 DAS was the same as for Gen1—to enhance driver confidence during bus shoulder operations, especially during adverse weather, to bypass traffic congestion when speeds in general-purpose lanes drop below 35 miles per hour. Secondary goals included reduced travel times, increased reliability and safety, and improved customer satisfaction.
