Abstract:
As a part of a research project sponsored by the Texas Department of Transportation, the Texas A&M Transportation Institute, along with Texas A&M University's (TAMU's) Transportation Services, Mobileye and Rosco Vision Systems, conducted a pilot of the Mobileye Shield+ pedestrian and bicyclist collision warning system using one TAMU bus on a campus route. The Shield+ system includes algorithms to track the distance and speeds of these pedestrians and bicyclists, which are continuously measured to calculate the risk of a collision. The pilot was conducted in early 2016. Changes were made to the machine vision algorithm after the pilot. This report summarizes a follow-up assessment that was concluded in summer 2016 to reduce unnecessary warnings.
The follow-up assessment indicated that the system produced fewer warnings from the left and right rear sensors than during the pilot. Direct comparisons with the initial evaluation earlier in 2016 are difficult since the bus was operated on additional routes and data were recorded at a different time of the academic year when there is a much smaller student population on campus. The assessment further indicated that the Shield+ system continues to be very accurate at detecting pedestrian and bicyclists in close proximity to the equipped bus. The Shield+ system warnings never required a bus driver to make a corrective driving maneuver to avoid a collision.
