Summary
This interim report documents the design of an on-road testbed vehicle intended to evaluate the effectiveness of collision avoidance systems for lane change crashes. The study aims to establish a foundation for estimating system effectiveness and to provide data for setting performance specifications by digitally recording ground truth, vehicle inputs, and driver behavior. The testbed features a scanning laser subsystem capable of detecting vehicles up to 200 feet away and an eye-tracking system that monitors driver gaze direction at 60 hertz during maneuvers. These components replace manual video review methods, allowing for precise measurement of parameters such as gap spacing, relative speeds, and gaze patterns. The report details the technical requirements, design approach, and implementation capabilities of the laser, video, eye-tracking, and data acquisition subsystems.
Key finding
The designed testbed vehicle integrates a scanning laser and eye-tracking system to digitally record ground truth and driver gaze data, enabling the empirical assessment of collision avoidance system effectiveness and the establishment of performance specifications for lane change maneuvers.
