The Vehicle-Infrastructure Cooperative Systems support driving, and aim to avoid traffic accidents by notifying drivers of the information obtained through communications between the vehicles and sensors installed on the road, or among vehicles.
Toyota has commercialized some functions of the system since October 2009 after participating in some proving tests held by the relevant governmental agencies and automotive industries.
Effects of Vehicle-Infrastructure Cooperative Systems
that support driving
As an addition to conventional ETC services, this system operates primarily on expressways and uses bidirectional communication between vehicles and infrastructure to provide traffic information services that support safe driving. Operation of this system started in 2009*, and Toyota began sales of an on-board unit for ITS spot services at the same time.
These systems are designed focusing on general roads to convey information about vehicles, motorcycles, and pedestrians that are difficult for drivers to see, as well as traffic control information (traffic signals, etc.) from the transport infrastructure to vehicles to help ensure the safe driving operation of this system started in 2011, and Toyota began sales of HDD Navigation System features DSSS at the same time.
The new generation of Vehicle Infrastructure Cooperative Systems uses direct communication between vehicles and pedestrians or among vehicles for continuous information exchange in order to prevent frontal collision accidents between vehicles and pedestrians at intersections difficult for drivers to see, which has been difficult to solve until now. Toyota is also developing the systems to contribute to the environment reform and to improvement of traffic flows, expanding vehicle-Infrastructure Cooperative Systems.
Toyota participates actively in the early practical application and moves forward with the development.
