nnovative vehicle-to-infrastructure communication system to help reduce traffic accidents and improve pedestrian safety
TOKYO, -- Nissan Motors Co., Ltd. announced today 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 light signals. 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*1, to collect real-world vehicle data from several hundred employee cars participating in the project.
The new advanced traffic system will help reduce accidents as well as ease traffic congestion - specifically at traffic light intersections - leading to improved on-the-road fuel consumption. Since October 2006, Nissan has been conducting various experiments under its ITS Project in Kanagawa to help reduce accidents and ease traffic congestion.
The test-phase conducted within Nissan’s premises is representative of real-world traffic conditions, where relevant data from vehicles can be collected and analyzed under a closely-monitored environment. The vehicle-data input and corresponding traffic-signal output from the intersections is computed by an advanced traffic light system specifically installed for the test program.
Two intersecting main roads, one running east-west for two kilometers and the other running north-south for one kilometer, each with multiple intersections and crosswalks, provide the basic parameters for the ITS experiment. Nissan has installed standard traffic lights and roadside optical beacons along these test-roads. Traffic data can be collected from the employee cars and shuttle buses without any on-board vehicle-modification. However, for specific data to support the development of the navigation program under testing, several hundreds employee cars will be equipped with the Vehicle Information and Communications System units.
