To provide a tunnel traffic flow monitoring system capable of accurately grasping a traffic state of a vehicle in a tunnel to perform necessary countermeasures.SOLUTION: A pair of vehicle sensors 60, 62 are arranged in the right and left vicinity in a tunnel longitudinal direction of a hydrant device 10 installed at a prescribed interval in the longitudinal direction of a tunnel 100, vehicles passing in front of the hydrant device 10 are detected, the vehicle information including at least the number of vehicles which have passed and their vehicle speed is measured for each installation place of the hydrant device 10 on the basis of the detection signal of the vehicle sensor 60, 62 and is sent to a disaster prevention receiving board. A traffic judging part of the disaster prevention receiving board obtains, for example, an average vehicle speed on the basis of vehicle measurement information measured on the hydrant device 10 side, displays a distribution of the average vehicle speed in the tunnel, and judges a vehicle traffic state such as a congestion occurrence in the tunnel.SELECTED DRAWING: Figure 1

    【課題】トンネル内の車両の通行状態を精度よく把握して必要な対処を可能とするトンネル内交通流監視システムを提供する。【解決手段】トンネル100長手方向に所定間隔で設置された消火栓装置10のトンネル長手方向となる左右近傍に一対の車両センサ60,62が配置され、消火栓装置10の前を通過する車両が検出され、車両センサ60,62の検出信号に基づいて、消火栓装置10の設置場所毎に、通過する車両の少なくとも台数及び車速を含む車両情報が測定され、防災受信盤に送られる。防災受信盤の交通判断部は、消火栓装置10側で測定された車両測定情報に基づいて例えば平均車速を求め、トンネル内における平均車速の分布を表示させ、トンネル内での渋滞発生等の車両交通状態を判断可能とする。【選択図】図1
