【００１４】８，８１は公知の車両検知装置であり、こ
こでは光透過型のエリアセンサで構成され、路面垂直方
向に光スクリーンが設けられている構成とする。Reference numerals 8 and 81 denote known vehicle detecting devices, each of which is constituted by a light-transmitting area sensor and provided with a light screen in a direction perpendicular to the road surface.
【００１５】９は公知の踏板である。この踏板９は車両
検知装置８，８１の光軸下の路面に設置され、車両１台
の識別と軸位置が検出できる公知の構成である。Reference numeral 9 denotes a known tread. The tread plate 9 is installed on a road surface below the optical axis of the vehicle detection devices 8 and 81, and has a known configuration capable of identifying one vehicle and detecting the axial position.
【００１６】踏板９とアンテナ５Ａ，５Ｂの設置は、次
の前提により設定する。The installation of the tread 9 and the antennas 5A and 5B is set based on the following premise.
【００１７】（１）．無線カードは運転手が手でかざす
（アンテナに向ける）。(1). The driver holds the wireless card by hand (points at the antenna).
【００１８】（２）．車両の運転席は１軸目の直後に、
２軸目は運転席の後方に平均的に分布している。(2). The driver's seat of the vehicle is right after the first axis,
The second axis is evenly distributed behind the driver's seat.
【００１９】（３）．アンテナの有効通信エリアは中心
線上で幅方向３ｍ（道路幅３ｍを越えない。隣車線との
混信防止のため）、進行方向３ｍ（車両の最少長３ｍを
越えない。後続車との混信防止のため）程度に調整す
る。(3). The effective communication area of the antenna is 3 m in the width direction on the center line (it does not exceed the road width of 3 m; to prevent interference with the adjacent lane), and the traveling direction is 3 m (it does not exceed the minimum length of the vehicle of 3 m. Adjustment).
【００２０】従って、アンテナ５Ａは車両が１軸目にか

かるよう踏板の後方に設置し、アンテナ５Ｂはそれより
更に平均軸間距離（２．５〜３ｍ）後方に設置する。Therefore, the antenna 5A is installed behind the tread so that the front edge of the communication area SA is covered by the antenna 5A when the vehicle hits the first axis, and the antenna 5B is further arranged at an average distance between the axes (2. 5-3m) Install behind.

要がない。The switching from the antenna 5A to the antenna 5B is performed by a signal of the second axis output from the vehicle detectors 8 and 81 (including the axis number counter of the tread 9), and the return of the antenna 5A is performed by the reading device. 6 or a timeout signal. If the communication completion signal is output before switching to the antenna 5B, there is no need to switch to the antenna 5B.
【００２２】以上のような構成によれば、車両の移動に

質上通信時間が増加し、車両が高速通過した場合の通信
時間不足を解消することができる。According to the above configuration, since the communication area can be moved with the movement of the vehicle (SA → SB), the communication time substantially increases, and the shortage of the communication time when the vehicle passes at high speed is solved. can do.
【００２３】尚、高速通過の場合、実質上、車両は連続

替わっているときに、踏板９の近くに後続車が突込むこ
とはない。In the case of high-speed passage, the vehicle does not substantially continue, so that when the operating antenna is switched to the antenna 5B, a following vehicle does not rush near the tread plate 9.
【００２４】低速の場合、車両は接近するが、通信時間
は十分大きいため、動作アンテナはアンテナ５Ｂに切替
わることもなく、かつアンテナ５Ａの通信エリアＳA は
最少長車両３ｍより拡がることはないから、後続車との
混信もなくなる。In the case of a low speed, the vehicle approaches, but the communication time is sufficiently long, so that the operation antenna is not switched to the antenna 5B, and the communication area SA of the antenna 5A does not extend beyond the minimum vehicle 3m. Interference with subsequent vehicles is also eliminated.

言うまでもない。Although the present invention has been described with reference to the case where the antenna is provided on the side of the road, the communication card 4 is mounted on the windshield of the vehicle as in the second embodiment shown in FIG. The antennas 5A and 5B are arranged on the front upper side, or the communication card 4 is mounted on the roof of the vehicle, and the antennas 5A and 5B are arranged right above as in the third embodiment shown in FIG. It goes without saying that such modifications are also included in the scope of the present invention.
