It is reported that more than half a million souls are lost per year due to traffic accidents throughout the world. These losses have been a very serious topic. Until now, no one could understand or supervise a driver's driving behavior in a closed space inside the vehicle unless a supervisor was with him in the same vehicle. However, recent computer and communication technologies have made it possible to obtain information concerning driving behavior and send it to a supervisor outside of the vehicle. It is believed that the most efficient opportunity to teach safe driving is when a driver is driving dangerously. The research team has therefore developed an Assistant System for Safe Driving by Informative Supervision and Training (ASSIST), a system created to prevent accidents based on our safe-driving theory. A laptop computer in the vehicle is connected to a D-GPS, a speed sensor, a laser radar distance measuring instrument, a C-MOS camera, and pedal sensors to obtain the driver's behavior such as position, speed, headway distance, front view images and movement of gas and brake pedals. A mobile phone that can transfer data at 28.8kbps is used for linkage between the laptop computer in the vehicle and the computer for the supervisor. The supervisor can know position, speed, adequacy of the headway distance, and stopping time at crossroads of the vehicle. An educational experiment was conducted regarding safe driving by the use of ASSIST and confirmed the effectiveness of the system. To supervise many drivers by one supervisor, a computer in each vehicle detects driver's dangerous behavior and sends the report to the supervisor in the case of need, instead of sending raw data continuously. The new ASSIST was developed to manage multiple vehicles about enough headway distance. For the covering abstract see ITRD E123876.
