Nissan advances testing of intelligent transportation system

Tokyo, Japan – Nissan Motors has announced that it will begin the next test phase of its intelligent transportation system (ITS) project, employing vehicle-to-infrastructure communication that allows synchronized communication between vehicles and traffic lights. Nissan will invest in the installation of an advanced traffic signal infrastructure within the site of the Nissan Technical Center, located in the Kanagawa Prefecture, to collect real-world data from several hundred employee cars participating in the project.

Nissan has been conducting various experiments under its ITS Project in Kanagawa since October 2006, with the goal of reducing collisions and easing traffic congestion.

The test phase is representative of real-world traffic conditions, where relevant data from vehicles can be collected and analyzed under a closely-monitored environment, while computing a number of scenarios. To help reduce pedestrian collisions, the system will calculate the optimal timing lapse between crossing pedestrians and the change in the traffic signal. Pedestrians often tend to ignore red signals at traffic crossings when they do not see vehicles; the current test program will contribute to Nissan’s research in finding ways to avoid such collisions.

To help reduce collisions due to traffic signal oversights, the system automatically appears on the navigation display as a vehicle enters within a specified distance to an approaching traffic light. Nissan is testing the possibility of providing higher levels of alert, control or even intervention when a driver fails to respond to the signal. Finally, the system will look at ways to reduce traffic congestion caused by red signals; Nissan is developing the system to optimize the timing intervals between changing traffic signals to correspond with real-time traffic volume and flow.
