DESCRIPTION AND PRELIMINARY DATA FROM TRW'S LANE CHANGE COLLISION AVOIDANCE TESTBED

TRW has built, under NHTSA contract, a fully automated data acquisition system for assessing the effectiveness of a lane change collision avoidance system. The system features two subsystems that allow for automated acquisition and analysis of data. The first is a scanning laser rangefinder which serves both as the collision warning sensor and collector of ground truth information. The second subsystem is an eye-tracker which outputs, at 30 Hz, the drivers gaze direction. Preliminary data, taken at a test track and on local freeways using team members, have refined the parameters that make up the driver warning algorithm. The data is consistent with a keep out zone adjacent to and 30 ft. behind the car and a 3 second time to arrival for fast approaching vehicles
