PROBLEM TO BE SOLVED: To provide a congestion alarm device and a congestion alarm system that alarm drivers of traffic congestion by placing congestion alarm devices on the road according to need in response to an unexpected accident and a hasty construction.SOLUTION: A plurality of congestion alarm devices are placed along a road in the order of an identification number given in advance from the smallest number from a downstream side toward an upstream side of the flow of vehicles traveling on the road. Each congestion alarm device comprises: a speed sensor for detecting the speed of a vehicle traveling on the road; an indicator for indicating the state of traffic congestion; a radio unit for communicating with other congestion alarm devices by radio; and a control unit for indicating, on the indicator, indication information corresponding to the state of traffic congestion corresponding to a change in the speed of the vehicle detected by the speed sensor, or the state of traffic congestion received from a congestion alarm device with a smaller identification number next to and at the downstream side of the congestion alarm device by the radio unit, and for transmitting the state of traffic congestion to a congestion alarm device with a larger identification number next to and at the upstream side of the congestion alarm device through the radio unit.SELECTED DRAWING: Figure 1

    【課題】道路上に必要に応じて設置して突発的な事故や急な工事に対応して交通渋滞の警報を行う。【解決手段】渋滞警報装置は、道路を走行する車両の流れの下流側から上流側に向けて、予め付与されている識別番号の若い番号の順に前記道路に沿って複数配置される渋滞警報装置において、道路を走行する車両の速度を検知する速度センサと、交通渋滞の状況を標示する標示機と、他の渋滞警報装置と無線通信を行う無線部と、速度センサにより検知された車両の速度の変化に応じた交通渋滞の状況、または無線部によりこの渋滞警報装置の下流側に隣り合う識別番号が小さい渋滞警報装置から受信された交通渋滞の状況に応じた標示情報を標示機に標示すると共に、この渋滞警報装置の上流側に隣り合う識別番号が大きい渋滞警報装置へ、交通渋滞の状況を、無線部を通じて送信する制御部とを備える。【選択図】図1
