[Standard Name]700 MHz Band Intelligent Transport Systems
[Enactment Date]2012/2/14
[Version] 1.2
[Revision Date]2013/12/10
[General Description]
In the autonomous type safety driving support system, there is a limit for the reduction of traffic accidents and the improvement of the environment due to a traffic jam, because information to be utilized is limited to vehicle information and onboard sensor information.
Therefore, the introduction of "a vehicle-infrastructure cooperative safety driving support system" to support safety driving is expected, through vehicle-to-vehicle and vehicle-to-infrastructure communications with exchanging of information thereby leading to the prevention of traffic accidents.
This standard attains "a vehicle-infrastructure cooperative safety driving support system" using the operating frequency of 700MHz band that has become available due to the digitization of Terrestrial TV Broadcasting.
Also, this standard specifies an interface for a wireless section between land mobile stations, and between a land mobile station and a base station of the “Radio Equipment of 700 MHz band Intelligent Transport Systems” specified in the Article 49-22-2 of the Ordinance Regulating Radio Equipment.
Noted that the reduction of the production cost and international standardization are also considered, for example by having the compatibility with the European and United States specifications with regard to the physical layer among the specifications specified in this standard.
