NISSAN TO TEST INTELLIGENT TRANSPORT SYSTEM USING CELL PHONES
TOKYO--Nissan Motor Co., Ltd. announced today that it is developing an advanced Intelligent Transportation System (ITS) employing cellular communications to help reduce accidents involving pedestrians. Nissan is also conducting research on pedestrian-related communication involving the transmitting of pedestrian position data to vehicles via the Global Positioning System (GPS).
Nissan's advanced ITS will employ the next 3G cellular communications system*1, launched from this April, where the GPS function is used as the basis to provide location information of the cellular phone. In this system, location data transmitted from the pedestrian's cellular phone and vehicle is fed to the ITS to allow the system to determine the corresponding positions between the pedestrian and the vehicle. A pedestrian alert will appear onboard the vehicle to warn the driver, helping to reduce road accidents particularly in a blind-spot situation.
This advanced ITS research consists of the following process:
Nissan is studying what types of pedestrian data are most relevant to help prevent accidents. The research will investigate a variety of factors influencing the pedestrian-vehicle's relative positions, such as the directions in which pedestrians and the vehicle are moving, and the corresponding speeds and distances between them. Various driver alerts, such as visual warnings or audible alarms, are also under study.
Nissan is studying and developing the ITS with technical collaboration from NTT DoCoMo Inc. on cellular communications technology.
This current research aims to join and contribute to the ITS project*4, which is a Nissan experimental program conducted in Kanagawa Prefecture that begun in October 2006. The program is aimed at efforts to help reduce traffic accidents and congestion utilizing real-time driving-data collected from the vehicles. The ITS project allows Nissan to test various technology concepts and develop the most suitable technology solution for wide-scale application.
