PROBLEM TO BE SOLVED: To provide an on-road installation type traffic sign monitoring system that senses both information which is needed to sustain an installed state with a simple configuration irrespective of the length of a passage regulation area, and information based on which rush of a traveling vehicle is alarmed, and that does not perform unnecessary notification.SOLUTION: Passage regulation areas 1a, 1b, 1c, 1d, etc. are sorted into plural areas juxtaposed along a traveling direction, and one repeater 30 is installed in each of the areas. One of the repeaters is regarded as a comprehensive repeater 31 that collects pieces of information from the other repeaters. A change in the state of an on-road installation type traffic sign 10 or 50 derived from a rushing vehicle is sensed area by area, and an alarm against the rushing vehicle is also given area by area. Changes in the installed states of the plural on-road installation type traffic signs are collected by the comprehensive repeater, and information concerning all the areas is stored in all the repeaters. Based on an information provision signal f5 sent from a repeater, monitoring means 40 reports the changes in the installed states of the plural on-road installation type traffic signs and the areas while moving through traffic regulation areas.SELECTED DRAWING: Figure 1

    【課題】通行規制領域の長さに関わらず簡単な構成で設置状態を維持する情報と、走行車両の突入を警報する情報の双方を検知し、かつ、不要な報知を行なわない路上設置型道路標識監視システムを提供する。【解決手段】通行規制領域1a、1b、1c、1d・・・が走行方向に沿って並ぶ複数のエリアに区分けされ、複数のエリアの各々には中継器30が一つ配置され、中継器の一つが他の中継器からの情報を収集する集約中継器31とされる。突入車両による路上設置型道路標識10、50の状態変化は、エリア毎に検知され、それに対する警報もエリア毎に実施される。複数の路上設置型道路標識の設置状態の変化は、集約中継器に集約され、全エリアに関する情報が全中継器に記憶される。監視手段40は、交通規制領域を移動しながら、中継器から送信される情報提供信号f5に基づき、複数の路上設置型道路標識の設置状態の変化があったこと及びそのエリアを報知する。【選択図】図1
