【発明の属する技術分野】
本発明は、道路交通分野における交通量と騒音、振動、衝撃並びに大気の汚染等の相関から環境保護に利用する交通量計測装置及びその方法に関する。
【０００２】
【従来の技術】
近年、道路交通の急速な発展に伴い、車両数の増加が続き、一般道路並びに高速道路に置いても交通渋滞と交通事故多発は深刻な社会問題を起こすようになってきた。その結果、道路において車両をいかに円滑に動かすかが最重要課題となっている。そのため、通過車両の数、種類、速度、車両の単位時間当たりの道路占有率の測定が必要になってきた。
【０００３】
図５は、従来の交通量計測装置の構成を示している。図５において従来の交通量計測装置は、道路の車線毎に設置された感知器２と接続され、車線毎に通過した車両の車種（大型、小型等の種別）、通過車両台数、速度等を計算する路側部計測装置１と、交通量や単位時間当たりの車両の道路占有率の算出及び車種等の時間当たり、１日あたり、月あたり等の統計データを計算するデータ処理装置３とから構成されている。
【０００４】
図６は、路側部計測装置１および感知器２の構成を更に詳細に示したものである。図６において、感知器２は、通過車両の車長、車両数及び速度等を感知する車長感知器2aと、通過車両の車高を感知する車高感知器2bとから構成され、また、路側部計測装置１は、それぞれの感知器2a、2bに対応する信号を増幅しパルス信号に変える感知ユニット1a、1bと、それぞれの感知ユニット1a、1bのパルス信号から車長、車高を計算し通過した車両の車種を判定する車種判別ユニット1cと、感知ユニット1a、1bのパルス信号から通過車両数、速度及び占有率を計算しデータ処理装置３にその結果を伝送する主処理ユニット1dから構成されている。
【０００５】
このように上記従来の交通量計測装置では道路の車線毎に設置された感知器２によって通過した車両を電磁的検出並びに超音波等の反射時間から車高を感知した信号から路側部計測装置１によって通過車種、車両数、速度及び占有率が計算でき又データ処理装置３でその統計処理ができるようになっている。
【０００６】
【発明が解決しようとする課題】
しかしながら、従来の交通量計測装置では感知器２が通過する車両を電磁的に検出及び、超音波やレーダによる反射の時間等による感知信号に限られているため、通過車両や車種等の交通量のみの検出で、最近、車両による大気汚染、振動及び騒音等の環境問題に対応できないという問題が生じている。
【０００７】
本発明は、このような環境改善問題に対する新たな社会的要請に応えるために交通量だけでなく交通量に対する騒音、振動並びに大気汚染等の環境データの同時測定を行なうとともに交通量と環境データの相関関係を求め、前記相関関係に応じて交通規制並びに速度規制の警告等を発することができる優れた交通量計測装置を提供することである。

従って、本発明によれば、騒音、振動及び大気汚染の度合いを測るＣＯ 2 、ＮＯｘ等を測定する環境データ感知器を車両感知器と併設することにより交通量と環境データが同時に測定でき、また交通量と環境データの相関関係を算出することにより、交通規制並びに速度規制の警告を発することが可能になり、環境保護や環境改善に効果を発揮する。
【００１５】
【発明の実施の形態】
本発明の請求項１に記載の発明は、道路上に設置され通過車両を検知する車両感知器と、車両による騒音を測定する騒音感知器、車両による振動又は衝撃を測定する感知器、大気中のＣＯ2、ＮＯｘを測定する感知器のいずれかで又は組み合せで環境データを測定する環境データ感知器とを備え、かつ前記車両感知器より信号を受けて処理する車両感知ユニットと、前記車両感知ユニットからのデータにより通過車両数、速度及び車種を判定する車種判別処理ユニットと、前記環境データ感知器より信号を受けて処理する環境データ感知ユニットと、前記環境データ感知ユニットからの信号を増幅しデジタル量に変換処理する環境データ処理ユニットと、前記車種判別処理ユニットおよび前記環境データ処理ユニットでそれぞれ処理された前記通過車両についてのデータと前記環境についてのデータを集計し、データ処理装置に通信回線を介して送信する主処理ユニットとを備える路側部計測装置と、前記路側計測装置から伝送されたデータに基づいて交通量と計測環境データについての統計データを算出し、かつ前記交通量と前記計測環境データとの相関関係を計算し警告装置に出力するデータ処理装置と、前記データ処理装置から出力された前記交通量と前記計測環境データとの相関関係に基づいて交通規制、速度規制などの警告を行なう警告装置を備えることを特徴とする交通量計測装置としたものであり、交通量と環境データの相関関係を算出することにより、測定した環境データに基づいて交通規制並びに速度規制の警告を発することが可能となるという作用を有する。
