Collision warning systems (CWSs) are becoming an important part of vehicle active safety. Commercial CWSs using radar, lidar, and camera have been available on the market. Another emerging trend in the development of CWS is based on the cooperative driving concept, where either the vehicle or the infrastructure can communicate its location, intention or other information to surrounding vehicles or nearby infrastructure. Since installing a lower-cost Global Positioning System (GPS) unit is becoming a common practice in vehicle applications, its implications in cooperative driving and vehicle safety deserve a closer investigation. This paper explores the feasibility of a cooperative CWS based on the proposed future-trajectory-based design, which estimates and communicates vehicle positions, and predicts and processes future trajectories for collision decision making. An exemplary system has been developed and the feasibility of the proposed design has been demonstrated with experimental data
