PROBLEM TO BE SOLVED: To provide new technical means for an appropriate response when radio communication abnormality has occurred based on the premise that road-to-road communication by radio lies in communication between a road-side device and a central device.SOLUTION: A road traffic control communication system comprises: a central device 10 for road traffic control; a master road-side device A connected with the central device by a wired line 2 and capable of communicating with the central device 10; and a slave road-side device B capable of communicating with the central device 10 via radio communication with the master road-side device A. When the central device 19 detects the occurrence of radio communication abnormality between the master road-side device A and the slave road-side device B, the central device 19 transmits a first instruction to cope with the radio communication abnormality to the slave road-side device B.

    【課題】路側機と中央装置との通信に、無線による路路間通信を介在させるという前提において、無線通信異常が生じた場合に適切に対処するための新たな技術的手段を提供する。【解決手段】交通管制用通信システムは、交通管制用の中央装置10と、前記中央装置に有線回線2で接続され、前記中央装置10と通信可能な親路側機Aと、前記親路側機Aとの間での無線通信を介して、前記中央装置10と通信可能な子路側機Bと、を備えている。前記中央装置19は、前記親路側機Aと前記子路側機Bとの間での無線通信異常の発生を検出すると、前記無線通信異常に対処させるための第1指示を、前記子路側機Bに対して送信する。【選択図】図1
