Abstract

The Rosco/Mobileye Shield+ system is a collision avoidance warning system (CAWS) specifically designed for transit buses. This project involved field testing and evaluation of the CAWS in revenue service over a three-month period. The system provides alerts and warnings to the bus driver for the following conditions that could lead to a collision: 1) changing lanes without activating a turn signal (lane departure warning was disabled for this pilot), 2) exceeding posted speed limit, 3) monitoring headway with the vehicle leading the bus, 4) forward vehicle collision warning, and 5) pedestrian or cyclist collision warning in front of, or alongside the bus. Alerts and warnings are displayed to the driver by visual indicators located on the windshield and front pillars. Audible warnings are issued when collisions are imminent. The project was conducted under the auspices of the Washington State Transit Insurance Pool (WSTIP). In addition to funding from TRB’s IDEA Program, funding was provided by WSTIP, Alliant Insurance Services, Inc., Government Entities Mutual, Inc., Pacific Northwest Transportation Consortium (PacTrans), and Munich Re America Inc. The contract was executed on January 19, 2016 with duration of eighteen months. Accomplishments documented in this report are based on our research objectives as stated in the IDEA contract.
