【００３５】
本実施形態の自動運転道路システムは、図４に示すように、高速道路などの道路に埋設されている地中ポール５を介して電界データ通信により道路を走行する車両に搭載された車載トランシーバ４１とデータ通信を行うべく道路に沿って設置される複数の設置データ埋め込みトランシーバ１、この複数の設置データ埋め込みトランシーバ１とデータ通信を行うべく基幹ネットワーク３を介して接続された交通監視基地局１０を有し、複数の設置データ埋め込みトランシーバ１が各車両に搭載されている各車載トランシーバ４１との地中ポール５と導電性タイヤ４７を介した電界データ通信により各車載トランシーバ４１から受信した車両情報を設置データとともに基幹ネットワーク３を介して交通監視基地局１０に送信すると、交通監視基地局１０がこの車両情報と設置データとに基づいて道路交通制御を行うための道路交通制御情報を生成し、この道路交通制御情報を基幹ネットワーク３を介して設置データ埋め込みトランシーバ１に送信し、設置データ埋め込みトランシーバ１において当該道路交通制御情報を設置データとともに地中ポール５を介して車載トランシーバ４１に送信し、車載トランシーバ４１において導電性タイヤ４７を介して道路交通制御情報と設置データを受信すると、この道路交通制御情報と設置データを車載コンピュータ４３に供給して車載コンピュータ４３により走行制御手段４５を介して車両の走行を制御し、これにより位置分解能の高い道路交通制御を適確かつ安全に行うものである。
【００３６】
次に、図１〜図４を参照して、上述したように構成される設置データ埋め込みトランシーバ１、車載トランシーバ４１、基幹ネットワーク３を用いた自動運転道路システムの作用について説明する。
【００３７】
図３に示すように、設置データ埋め込みトランシーバ１の地中ポール５が一部露出もしくは地中浅く埋設されている道路上を車両１０１，１０２などが走行すると、車両１０１の車載トランシーバ４１に接続されている導電性タイヤ４７が設置データ埋め込みトランシーバ１の地中ポール５と接触し、この導電性タイヤ４７と地中ポール５とを介して車載トランシーバ４１と設置データ埋め込みトランシーバ１との間で電界データ通信が行われ、車載コンピュータ４３からの車速情報や車体番号などを含む車両情報が車載トランシーバ４１の入出力回路５１、送信回路５３、送信電極５５、導電性タイヤ４７を介して設置データ埋め込みトランシーバ１の地中ポール５に電界として伝達される。
【００３８】
車載トランシーバ４１からの車両情報に対応する電界は、設置データ埋め込みトランシーバ１の地中ポール５に誘起され、受信電極２１で受信され、電界検出光学部２３で電気信号に変換され、受信回路２４から車両情報として第２合成回路２９に供給される。第２合成回路２９は、この車両情報を設置データ発生回路１３からの位置情報、路面情報、気温情報、天候情報などを含む設置データと合成し、この合成した車両情報と設置データを入出力回路１１から基幹ネットワーク３を介して交通監視基地局１０に送信する。

【００４２】
上述したように、車載トランシーバ４１は、設置データ埋め込みトランシーバ１を介して道路交通制御情報および設置データを受信することにより、設置データに含まれる位置情報から現在位置を正確に知ることができるともとに、交通監視基地局１０からの道路交通制御情報に基づき適正な走行制御、例えば車間距離の制御、車速制御、迂回道路への道路変更制御などの走行制御を行うことができる。
【００４３】
また、交通監視基地局１０は、設置データ埋め込みトランシーバ１を介して車載トランシーバ４１からの車両情報および設置データ埋め込みトランシーバ１からの設置データに基づき各車両の速度や車間距離などの走行状態を適確に把握し、各車両が適正な走行動作を行っているか否かを判定することができ、必要により道路交通制御情報に含ませて警報を各車両に送信することもできるし、また車両情報および設置データに基づき各車両の正確な現在位置を把握して適正な道路交通制御情報を生成し、この道路交通制御情報を設置データ埋め込みトランシーバ１を介して各車両に送信することにより、適正な走行制御を行うことができる。
