Nissan Motor Co., Ltd. today announced that four advanced Cooperative Intelligent Transport technologies will be shown at the 15th World Congress on Intelligent Transport Systems (ITS). The ITS World Congress, which is being held at New York City’s Jacob K. Javits Center from Nov. 16 - 20, showcases future vehicle-to-vehicle and vehicle-to-infrastructure communications systems.

The systems on display include Signal Violation Warning, Cross Traffic Notification, Oncoming Traffic Notification and Cooperative Intelligent Cruise Control. Nissan is developing these advanced systems for future applications to help inform the driver and help control the vehicle, with the goal of contributing to improved traffic safety as the infrastructure is implemented. Following are brief descriptions of each:
Signal Violation Warning: If the vehicle is approaching an intersection with a red light or a light that will soon turn red without the driver applying the brakes, the Signal Violation Warning system issues visual and audible warnings to notify the driver of impending danger. These warnings are generated based on the traffic signal phase (color and duration), vehicle speed and distance to the intersection. The system calculates when the vehicle will arrive at the intersection and issues a warning if a conflict is anticipated.

Cross Traffic Notification: As the vehicle approaches an intersection without a traffic signal, the system will issue a crossing traffic notification to warn the driver of potentially unseen cross traffic. Warnings are generated based on information received from other vehicles and distance to the intersection.

Oncoming Traffic Notification: If the vehicle is in the left turn lane, the system will issue a warning of oncoming traffic based on information received from the other vehicles and vehicle location.

Cooperative ICC: If the vehicle using ICC approaches an intersection with a red light or a light that will soon turn red, the system will apply the brakes and bring the vehicle to a stop near the stop line.

These future systems are based on research and development conducted by Nissan as part of the U.S. Department of Transportation Vehicle Infrastructure Integration (VII) program over the past three years. These advanced systems utilize dedicated short range communication (DSRC) technology between road side equipment (RSE), on-board equipment (OBE) in the vehicle and other vehicles, and GPS-assisted high-accuracy vehicle positioning technology.

The vehicles equipped with the GPS receiver and OBE recognizes high accuracy map information, determines approximate vehicle positions, and receives traffic signal information when approaching intersections.

On a global level, Nissan is committed to build safer vehicles equipped with advanced safety technologies. In Japan, the company’s safety vision is to halve the number of traffic fatalities or serious injuries involving Nissan vehicles by 2015 compared with the level in 1995.
