Cooperative ITS support driving and aim to prevent traffic accidents by notifying drivers of information, which cannot be detected by a vehicle's own sensors, through communications between vehicles and infrastructure, or among vehicles.
Toyota commercialized certain functions of Cooperative ITS in 2009 after participating in proving tests held by government agencies and automotive industries, which began in 2006.
Toyota seeks to continuously improve and promote systems for a sophisticated traffic environment, leading to a safer and more comfortable society.
Effects of Vehicle-Infrastructure Cooperative Systems
that support driving
In addition to conventional ETC services, this system operates primarily on expressways using bidirectional communication between vehicles and infrastructure to provide traffic information services that support safe driving. Operation of DSRC started in 2009, and at the same time, Toyota began sales of ITS spot compatible on-board equipment (OBE)*.
Furthermore, Toyota is working to systematically increase the number of vehicle models which support the service.
DSSS are designed with a focus upon public roads to convey information about things that are difficult for drivers to see. In addition, traffic control information (traffic signals, signs, etc.) from infrastructure is sent to vehicles to help ensure safe driving. Operation of this system commenced in 2011, and Toyota integrated DSSS into navigation systems at that time.
Toyota has been working on the commercialization of a new system that runs on the 700MHz band and connects pedestrians, vehicles and infrastructure.
The 700MHz band allows continuous communication over wide areas and easily overcomes obstacles. Therefore, it is an ideal system to prevent accidents such as right-turn collisions and crossing collisions involving pedestrians and other vehicles at intersections with poor visibility.
Toyota is active in the early practical application of this system and is moving forward with development.

Toyota began full-scale operations at its ITS Proving Ground, a new test site within the grounds of the Higashi-Fuji Technical Center in Susono City, Shizuoka Prefecture, in April 2012. Urban intersections found in Japan were replicated, and beacons, 700MHz communication equipment and vehicle/pedestrian detection sensors were installed.
At the purpose-built ITS Proving Ground, Toyota is working toward the early practical adoption of evermore reliable systems by repeatedly conducting tests and evaluations that can be difficult to perform on real roads due to changing road environments.
