PROBLEM TO BE SOLVED: To provide signal information of an intermediate inflow passage more quickly to a vehicle while preventing overlapped provision of the signal information of the intermediate inflow passage.SOLUTION: This invention relates to a radio communication system which includes an on-vehicle radio device 4 capable of inter-vehicle communication, and first and second radio devices 3A, 3B capable of road-vehicle communication with the on-vehicle radio device 4. The first radio device 3A at a first intersection J1 transmits signal information on a first inflow passage L4 from a second intersection J2 to the first intersection J1 with a first frame being an inter-road communication frame. The second radio device 3B at the second intersection J2 transmits the signal information of the first inflow passage L4 included in the received first frame with a second frame being a road-vehicle communication frame.SELECTED DRAWING: Figure 8

    【課題】 中間流入路の信号情報の重複提供を防止しつつ、中間流入路の信号情報をより早く車両に提供する。【解決手段】 本発明は、車車間通信が可能な車載無線機4と、車載無線機4との路車間通信が可能な第1及び第2無線機3A,3Bとを含む無線通信システムに関する。第1交差点J1の第1無線機3Aは、第2交差点J2から第1交差点J1に向かう第1流入路L4の信号情報を、路路間通信フレームである第1フレームにより送信し、第2交差点J2の第2無線機3Bは、受信した第1フレームに含まれる第1流入路L4の信号情報を、路車間通信フレームである第2フレームにより送信する。【選択図】 図8
