Conventionally, systems for communicating road information have been separately constructed using different specifications. Such construction resulted in the existence of various communication systems and non-uniform definitions for information contents, which hinders both the exchange and joint use of information among such systems.
Although systems that have similar performances are deployed throughout Japan, no system is efficiently constructed since each system is separately developed.
It has been suggested that the use of devices that do not have common specifications and the prolonged use of out-of-date technologies increase the construction costs of the systems.
The Road Communication Standard aims to solve these problems, promote information exchange and joint use of information by improving interconnectivity, operability and compatibility among systems and devices, formulate a common basis for system expansion and development, reduce life-cycle costs of the system and improve the efficiency of system designing and procurement.
