Abstract :
Vehicle-infrastructure Cooperative Systems (In this paper we call it “ITS” because of a space constraint) is one of measures that may help to reduce traffic accident through vehicles and roadside infrastructure work together [1]. It provide driver cognitive support to prevent miscalculation or against the traffic rule through communication between road infrastructure and vehicles about traffic regulatory information or existence of pedestrians and other vehicles. It originally expected 720-MHz band for Vehicle-infrastructure Cooperative Systems and now 760MHz band is allocated for this service. In any case, the frequency band closes a mobile phone frequency.
