A way of Toyota City equipped with a system for transmitting information to vehicles with traffic lights system on board, through the frequency band MHz 700 be used. The system receives the information and, if necessary, notify the occupants of the vehicle through the audio system and the navigation system screen. Together with the independent TMC to look better drivers running red lights, is expected to promote deceleration when approaching a red light, the system helps reduce emissions CO2.
The transmission of traffic lights has been possible thanks to the collaboration with the National Police Agency and the Police Prefecture Aichi (Japan).
These tests analyze the TMC driver behavior in different circumstances, to understand the extent to which systems vehicle-infrastructure cooperation can help reduce traffic accidents and emissions CO2, and incorporate data from future development of ITS technology.
From the concept of comprehensive security management, TMC is taking steps to develop their systems of vehicle-infrastructure cooperation assistance to safe driving, using ITS technologies to connect people, vehicles and traffic environments. TMC has been used in road tests the frequency band 700 MHz (assigned by the Japanese government for STIs) since March last year, in a system of care designed to prevent collisions caused by driver error.
(1) Systems that seek to prevent accidents by alerting the driver of dangerous situations, providing visual and audio information on traffic conditions in the vicinity, reduce environmental impact and emissions and create a more comfortable driving environment.
(2) Conduct studies, research and development in systems of universal traffic management (UMTS, Universal Traffic Management Systems). UTMS Japan aims to contribute to social welfare by promoting intelligent road transport, fluidity and ensuring safety and harmony with the environment.
(3) Standard STI 700 MHz band (ARIB STD-T109). Since this method of communication involves electromagnetic waves with excellent propagation characteristics are expected to be effective to prevent vehicle collisions at intersections and collisions with vehicles traveling in the opposite direction to make right turns.
(4) ITS type that receives information-including traffic control information (eg traffic lights cycles) and other aspects that can not directly see the driver-from wireless communications infrastructure installed on the tracks and other vehicles. By providing this information to the driver, the system allows a safer driving helps prevent accidents.
