To provide an on-road installed type road sign that can differentiate state change of low danger from that of high danger to be detected and notified without lowering efficiency of installing operation.SOLUTION: In the inner space of a sign body 10, a triaxial impact sensor, sensor computing means connected to the triaxial impact sensor, and transmitting means connected to the sensor computing means are provided in such a manner that they can be freely attached and detached. The sensor computing means acquires impact acceleration data from the triaxial impact sensor, and performs comparison computation on the impact acceleration data with respect to a first threshold value indicating state change of low danger extent and a second threshold value indicating state change of high danger extent which is higher than the first threshold value. The transmitting means, based on the results of the comparison computation, transmits a first notification signal when the impact acceleration data does not exceed the second threshold value but exceeds the first threshold value, and transmits a second notification signal when the impact acceleration data exceeds the second threshold value.SELECTED DRAWING: Figure 1

    【課題】設置作業の効率を低下させることなく、状態変化を危険性の低い場合と高い場合に区別して検出して報知できる路上設置型道路標識の提供。【解決手段】標識本体10が有する内部空間に、三軸衝撃センサと、前記三軸衝撃センサに接続されたセンサ演算手段と、前記センサ演算手段に接続された送信手段が着脱自在に配置される。前記センサ演算手段は、前記三軸衝撃センサから衝撃加速度データを取得し、前記衝撃加速度データと、危険度の低い状態変化を示す第一閾値、及び、前記第一閾値より大きく危険度の高い状態変化を示す第二閾値との比較演算をする。前記送信手段は、前記比較演算の結果に基づき、前記衝撃加速度データが前記第二閾値を超えず前記第一閾値を超えた場合に第一報知信号を送信し、前記衝撃加速度データが前記第二閾値を超えた場合に第二報知信号を送信する。【選択図】図1
