April 18, 2007 We’ve written before about Intelligent Transportation Systems in general and in particular, Nissan’s ongoing development and trials of Intelligent Transportation Systems in Japan, but a new development is the use of cell phone technology to help reduce accidents involving pedestrians. Nissan is researching the pedestrian-related communication involving the transmitting of pedestrian position data to vehicles via the Global Positioning System (GPS). Nissan's advanced ITS employs the next 3G cellular communications system, just launched in Japan, 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.
