PROBLEM TO BE SOLVED: To display the position information of a pedestrian, a bicycle, a motorcycle, a wheelchair, and an automobile at a predetermined position that is easy to see in association with an actual position.SOLUTION: In a traffic safety system configured of a plurality of radio tags TAG1 to TAG3 provided at traffic lights and first multifunctional communication equipment SP1 and second multifunctional communication equipment SP2 owned by a pedestrian, a bicycle, a motorcycle, a wheelchair, and an automobile, the first multifunctional communication equipment SP1 includes: a ranging device for measuring distances to the plurality of radio tags from the reciprocation time of a radio signal; and a position calculation device for calculating the position of the ranging device from a plurality of measured distances. After the position calculation device calculates the position information, radio communication equipment in the first multifunctional communication equipment SP1 transmits the position information, and radio communication equipment in the second multifunctional communication equipment SP2 receives the position information, and a display device of the bicycle, the motorcycle, the wheelchair, and the automobile displays the received position information in association with the actual position.SELECTED DRAWING: Figure 1
【課題】歩行者・自転車・バイク・車椅子・自動車の位置情報を実際の位置に対応させて、所定の見やすい位置に表示させる。【解決手段】信号機に設置された複数の無線タグTAG1〜TAG3と、歩行者・自転車・バイク・車椅子・自動車が有する第一の多機能通信装置SP1及び第二の多機能通信装置SP2からなる交通安全システムにおいて、第一の多機能通信装置SP1は、複数の無線タグまでの距離を無線信号の往復時間から測定する測距装置と、複数の測定した距離から測距装置の位置を算出する位置算出装置とを備える。位置算出装置が位置情報を算出後、第一の多機能通信装置SP1内の無線通信機により、当該位置情報を送信し、第二の多機能通信装置SP2内の無線通信機は、位置情報を受信し、受信した位置情報を実際の位置に対応させて自転車・バイク・車椅子・自動車の表示装置に表示させる。【選択図】図1
