技術分野  Technical field
[0001] バス等公共の車両の停留所にぉ 、て、 RFID (Radio Frequency Identification)タグ を用いてその運行情報を利用者にリアルタイムで提供する技術に関する。  [0001] The present invention relates to a technology for providing operation information to a user in real time using a RFID (Radio Frequency Identification) tag at a stop of a public vehicle such as a bus.
背景技術  Background art

In a crowded situation, the diamonds attached to the bus stops along the route are only a guide, and the user has no way of knowing the passing information of the vehicle. They have a great deal of inconvenience, such as waiting for a long time or being able to judge other people's ability to use other means of transportation.
[0003] こうした問題を解決するために、停留所にディスプレイを備え、利用者に現在の運 行状況を表示するいくつかのシステムが提案されている(特許文献 1、 2など)。  [0003] In order to solve these problems, several systems have been proposed that include a display at a stop and display the current operation status to the user (Patent Documents 1, 2, etc.).
[0004] 特許第 3393163号公報の「バス時刻表システム」では、実際の運行状況からバス の発車時刻を予想して表示する停留所のシステムが提案されている。  [0004] In the "bus timetable system" of Japanese Patent No. 3393163, there is proposed a stop system that predicts and displays the departure time of a bus from the actual operation status.
[0005] また、特開 2002— 109688号公報の「バス運行表示システム」では、複数のバス停 留所にバス時刻を記憶させておき、バスとの間で送受信することで、到着 Z通過を検 知し、現在時刻における運行状況を停留所のディスプレイに表示する技術が提案さ れている。  [0005] In addition, in the “bus operation display system” disclosed in Japanese Patent Laid-Open No. 2002-109688, bus times are stored in a plurality of bus stops, and are transmitted to and received from the bus to detect arrival Z passage. A technology has been proposed to display the operation status at the current time on the display of the bus stop.
[0006] し力しながら、停留所において、バスと情報を交信する受発信装置を備えたり、それ によって得られる運行状況のデータを表示するディスプレイを備える上記の従来技術 は、利用者に便宜を与えるものの、システム構築のためのコストや運用及び保守のコ ストが嵩むと 、う問題を抱える。  [0006] However, the above-described conventional technology, which includes a display device that includes a transmission / reception device that communicates information with a bus at a bus stop and a display that displays data on the operation status obtained thereby, provides convenience to the user. However, if the cost for system construction and the cost of operation and maintenance increase, there are problems.
