To suppress an accident that occurs at an intersection by using a transmission and a reception of radio waves.SOLUTION: A detection notification system is comprised of: a notification control unit that receives radio waves and controls a notification device; a first transmitter installed near an intersection and capable of transmitting a first radio wave to a first communication range; a second transmitter installed near the intersection and capable of transmitting a second radio wave to a second communication range narrower than the first communication range; and a transceiver that receives the first radio wave and the second radio wave, and transmits a third radio wave to the notification control unit, the transceiver being a portable transceiver, in which: at least a part of the communication ranges of the first transmitter and the second transmitter overlaps with each other; the transceiver changes the presence or absence of transmission of the third radio wave according to reception states of the first radio wave and the second radio wave, and the moving speed classification of the transceiver; and when the notification control unit receives the third radio wave, the notification control unit makes a notification using the notification device.SELECTED DRAWING: Figure 2

    【課題】電波の送受信を利用することにより交差点で発生する事故を抑制する。【解決手段】検知通報システムは、電波を受信すると共に、報知器を制御する報知制御部と、交差点近傍に設置され、第1の通信範囲に第1の電波を送信可能な第1送信機と、交差点近傍に設置され、第1の通信範囲よりも狭い第2の通信範囲に第2の電波を送信可能な第2送信機と、可搬型の送受信機であって、第1の電波と第2の電波とを受信し、報知制御部へと第3の電波を送信する送受信機と、を備え、第1送信機と第2送信機とは、互いの通信範囲の少なくとも一部が重複しており、送受信機は、第1の電波及び第2の電波の受信の状況と、送受信機の移動速度区分と、に応じて、第3の電波の送信有無を変更し、報知制御部は、第3の電波を受信すると、報知器を用いて報知する。【選択図】図2
