Nissan Motors displayed advanced intelligent transport technologies at the 15th World Congress on Intelligent Transport Systems (ITS), held in New York from 16 -20 November 2008. The company showed four new technologies which include Signal Violation Warning, Cross Traffic Notification, Oncoming Traffic Notification and Cooperative Intelligent Cruise Control.
Nissan have been developing these technologies for future applications to inform the driver and aid in control of vehicles and thus improving automotive safety. These new technologies are based on the R&D conducted by the company as part of the US Department of Transportation Vehicle Infrastructure Integration (VII) program for the past three years.
Cross Traffic Notification notifies the driver when the vehicle approaches an intersection which has no traffic signal. It helps the driver by warning of potentially unseen cross traffic. The device generates warnings considering information received from other vehicles and distance to the intersection.
Oncoming Traffic Notification informs driver about the oncoming traffic when the vehicle is in the left turn lane. The device notifies the driver taking into account information received from other vehicles and vehicle locations.
Cooperative Intelligent Cruise Control: This technology is useful for the vehicle which has intelligent cruise control technology. When the vehicle approaches at an intersection where traffic signal is red or it is about to turn red, Cooperative ICC will apply the brakes automatically and bring the vehicle to a stop near the stop line.
The four technologies use Dedicated Short Range Communication (DSRC) technology between Road Side Equipment (RSE), On-Board Equipment (OBE) in the vehicle and other vehicles, and GPS-assisted vehicle positioning technology. The vehicle takes into account map information, determines vehicle positions and receives traffic signal information when approaching intersections.
