Error Analysis and Performance Evaluation of a Future-Trajectory-Based Cooperative Collision Warning System

In this paper, the authors describe a future-trajectory-based cooperative collision warning system (CCWS). The system is designed to estimate and communicate vehicle positions as well as predict and process future trajectories for collision decision making. The authors focus on the robustness and reliability of the system by analyzing the error propagation and its impact on detection performance. The reliability of the CCWS is very dependent on the reliability of the Differential Global Positioning System (DGPS)-based positioning system and the reliability of vehicle to vehicle communication. Kalman filtering is used to statistically characterize the errors in position estimation and trajectory prediction. Communication errors are incorporated as part of the prediction error, and the probability of conflicts and the quality of the detection performance are determined. The reliability of the system is seen through results with experimental data illustrating the error propagation.
