Abstract:Collision-avoidance systems under development in the U.S.A., Japan and Germany were evaluated. The performance evaluation showed that the signal processing and the control law of a system were the key parameters that decided the system's capability, in terms of target discrimination, and the ability to avoid false alarms and missed targets. The benefits evaluation of selected radar systems was conducted using the Kinetic Research Accident Environment Simulation and Projection (KRAESP) Model and an accident data base which was adjusted to be nationally representative. The results indicated that radar braking systems were most effective in the rear impact mode as well as substantial benefits in frontal, vehicle-to-vehicle, and fixed-object impacts. The effectiveness of the radar systems in the side impact mode was very limited. Non-motorist impacts may be avoided by radar braking systems; however, the ability of the radar to detect pedestrians, bicyclists, and motorcyclists needs further study.
