Nissan moves to reduce accidents


Nissan will begin testing a newly-developed intelligent transportation system which allows vehicle-to-infrastructure communication to help reduce traffic accidents and ease congestion.

The test, which is being conducted to evaluate the receptivity of drivers to such a system, will run from October 1, 2006 until the end of March, 2009 in Kanagawa Prefecture, about 25km southwest of Tokyo.

About 10,000 drivers, who must be subscribers to Nissan’s “Carwings” navigation service, are expected to participate in the test.

The advanced road traffic system uses information obtained from nearby vehicles and roadside optical beacons to alert drivers to potential danger from approaching vehicles. The information is received by an onboard antenna on the vehicle. In addition, the system warns drivers when they are speeding in school zones.

It also provides drivers with fastest-route information using probe data – information on the position and speed of vehicles obtained by wireless communications technology.

Among the components tested will be a vehicle alert system, which alerts drivers to other vehicles moving too fast at blind intersections, and a speed alert which warns the driver that he or she is approaching a stop sign or a traffic light too fast.
The “Dynamic Route Finder”, a system informing drivers of the quickest route to their destination, will also be tested.

The route finder uses probe data collected from mobile phones of Carwings subscribers, including taxi owners, as well as vehicle data collected by a mobile phone operator.

All of the data is sent to Nissan’s probe server where it is collectively processed into traffic information. The data is then sent to the driver’s navigation screen where it is displayed in the form of real-time maps.

Based on the results of the test, Nissan is planning to implement its intelligent transportation system in Japan, and then globally in the future, to help reduce traffic accidents and congestion.

In Japan, Nissan has set a target of, by 2015, halving the number of traffic fatalities or serious injuries involving Nissan vehicles compared with number of accidents in 1995.
