Choose a higher combination.
- FIG. 6 is a flowchart illustrating an example of a processing procedure in which the monitoring plan evaluation server device 100 selects at least one of a plurality of monitoring location candidates that are monitoring execution condition candidates. For example, when a user operation for instructing selection of the monitoring execution condition candidate information is performed, the monitoring plan evaluation server apparatus 100 performs the processing illustrated in FIG. In the process of FIG. 6, the communication unit 110 acquires trip data and billing information from the billing server device 200 (step S101).

Abstract
Description
例えば、特許文献1には、GPS(Global Positioning System、全地球測位システム)によって通行車両の位置標定を行ない、課金条件と車両の位置情報とに基づいて課金処理を行う料金徴収用車載器が記載されている。
このような、車載器が車両の位置情報に基づいて課金処理を行う方式では、路側設備がない場所でも車載器が自律的に課金処理を行うことが可能である。従って、この方式では、路側設備を削減することができ、また、課金条件の設定や変更を柔軟に行うことができる。
特に、車載器が自身の位置に基づいて自律的に課金処理を行う場合、外部で課金処理を行わないので、車載器を車両から取り外す不正が行われると、課金処理時に外部から不正を検出することができない。従って、車載器を搭載すべき状況(例えば、全車に搭載が義務付けられている状況)にもかかわらず、車載器を取り外す不正が行われてしまうと、当該不正を行われた車両では、必要な課金処理が行われないこととなってしまう。このため、車載器が自律的に課金処理を行う場合には、車両を監視して不正車両を検出し取り締まることの必要性がさらに高まっている。
しかしながら、上記車載器の不正など、取り締まるべき不正が行われている車両の通行状況は場所や時刻によって異なると考えられ、取り締まりを行うための監視を行う場所や時刻によって不正が行われている車両の検出状況は異なると考えられる。そこで、不正が行われている車両を効率よく検出できる場所及び時刻の少なくとも一方を予測できることが望まれる。
ここで、監視を実施すべき車両とは、車両に関する不正が行われた蓋然性が高かまっているため、監視の必要性が高まっている車両のことである。
これにより、候補選択部が選択した場所または時刻に従って監視用のシステムを設置することで、不正が行われた車両の検出を効率よく行うことができる。
これにより、車載器を搭載していない車両の検出を効率よく行うことができると予想される地点を、通行程度情報を構成する地図情報で確認しながら、監視を行う場所や時間を決定することができる。
これにより、通行程度情報生成部は、高額の課金逃れを防止または検出するための監視に適した場所または時刻を提示することができる。このため、例えば自動課金システムの運用者は、当該場所または時刻にて監視を行うことで、高額の課金逃れを防止または検出するための監視を効率よく行うことができる。
以下、本発明の実施形態を説明するが、以下の実施形態は請求の範囲にかかる発明を限定するものではない。また、実施形態の中で説明されている特徴の組み合わせの全てが発明の解決手段に必須であるとは限らない。
図1は、本発明の一実施形態における自動課金システムの機能構成を示す概略ブロック図である。同図において、自動課金システム1は、監視計画評価用サーバ装置100と、課金用サーバ装置200と、監視用サブシステム400とを備える。監視計画評価用サーバ装置100は、通信部110と、表示部120と、記憶部180と、制御部190とを備える。制御部190は、通行程度情報生成部191と、候補選択部192とを備える。本実施形態で、監視用サブシステム400は、課金用サーバ通信装置410と、カメラ420と、DSRC(Dedicated Short Range Communication)通信装置430と、制御装置490とを備える。
また、課金用サーバ装置200は、車載器310が搭載された車両300のユーザに対して、車載器を利用して課金処理をするために、車載器310との間で通信を行う通信手段を有する。当該通信手段としては例えば携帯電話通信網などを利用した広域通信が可能な手段が挙げられるが、これに限らない。また、監視用サブシステム400におけるDSRC通信装置430は、狭域通信が可能な手段であり、監視用サブシステム400が設置された位置近傍の監視ポイントを通行する複数の車両300の各々が備える車載器310と通信を行う。なお、監視用サブシステム400が車載器310と通信を行う手段として、DSRC通信装置430は一例であり、例えば広域通信が可能な手段としても良い。
自動課金システム1による課金では、車載器310が、課金条件が成立したことを検出すると課金処理を行う。課金条件の例として、車両が特定の場所を走行したことを挙げることができるが、これに限らない。例えば、課金条件が、車両が特定の時間帯に特定の場所を走行したことであるなど、時刻に関する条件を含んでいてもよい。また、特定のエリア内で、所定の距離ごとに課金するなど、距離に関する条件を含んでいてもよい。
ここでいう車両とは、自動車や二輪車など、道路を走行する乗り物である。また、ここでいう場所は、道路、または、道路の区間であってもよいし、複数の道路の少なくとも一部を含む区域であってもよいし、地点であってもよい。ここでいう地点は、点であってもよいし、道路の幅方向の線であってもよい。
図2は、課金情報のデータ構造の例を示す説明図である。同図において、課金情報は表形式のデータとして構成されており、各行において、車載器IDと、課金位置と、課金時刻と、課金内容とが対応付けられている。ここでいう車載器IDとは、車載器を識別するための情報である。
かかるデータ構造により、課金情報において、どの車載器が搭載された車両に対してどこの課金ポイントでいつ、幾らの課金が行われたかが示されている。
図3は、トリップデータのデータ構造の例を示す説明図である。同図において、トリップデータは表形式のデータとして構成されており、各行において、車載器IDと、走行位置と、走行時刻とが対応付けられている。かかるデータ構造により、トリップデータにおいて、どの車載器が搭載された車両がどこをいつ走行したかが示されている。
また、車載器310は、監視用サブシステム400からの問い合わせに対して、車載器310自らが車両に搭載されていることを示す情報を監視用サブシステム400へ送信する。車載器310自らが車両に搭載されていることを示す情報として、車載器IDを用いることができるがこれに限らない。
監視用サブシステム400は、本実施形態では、車載器310を搭載していない車両を検出する。以下では、全ての車両に車載器310を搭載することが義務付けられている場合を例に説明するが、本実施形態の適用範囲はこれに限らない。例えば、課金ポイントを通過する全車両に車載器310を搭載することが義務付けられている場合、監視用サブシステム400が、課金ポイントを通過した直後の車を対象に、車載器310を搭載していない車両を検出するようにしてもよい。ここでいう課金ポイントとは、課金が行われる場所である。
具体的には、制御装置490は、カメラ420の画像に車両の像が含まれるか否かを判定することで、監視ポイントに位置する車両の有無を判定する。そして、制御装置490は、画像に車両の像が含まれている場合には、当該画像に含まれている車両のナンバープレートをパターン認識し、認識したナンバープレートに表示された車両ナンバーをOCR処理などによって抽出する。また、監視ポイントに位置する車両が存在すると判定した場合、制御装置490は、DSRC通信装置430によって車載器310と通信が確立したか否かによって、当該車両が車載器310を搭載しているか否かを判定する。そして、制御装置490は、DSRC通信装置430と車載器310との通信が所定時間確立しなかった場合には、車載器310を搭載していない不正を行っている車両を検出したことを示す情報と当該車両の車両ナンバーとによって、監視対象となった車両の情報を構成する。そして、制御装置490は、該監視用サブシステム400で監視を行った車両300の監視場所及び監視時刻に関する監視実施条件情報と、当該監視対象となった車両の情報とを含む車両監視情報を、課金用サーバ通信装置410を介して課金用サーバ装置200へ送信する。
このように、監視用サブシステム400は、監視場所に設置して、カメラ420やDSRC通信装置420により車両の情報を収集することで、走行する車両の客観的な走行の事実を収集することが可能となり、不正が行われている車両を監視するに際しての証拠性を高めることが可能となる。また、監視用サブシステム400は、課金用サーバ通信装置410により課金用サーバ装置200へ収集した車両の情報を送信することができることで、収集した車両の情報の蓄積、分析を効率良く行うことが可能となる。
また、監視用サブシステム400が、特定の監視ポイント専用に、当該監視ポイント近傍の特定の位置に設置されていてもよい。あるいは、監視用サブシステム400が車両に設置されているなど、移動可能に設置されていてもよい。
監視計画評価用サーバ装置100は、監視計画の評価システムの例に該当する。但し、監視計画の評価システムは、1台の装置として構成されていてもよいし、複数の装置を組み合わせて構成されていてもよい。
表示部120は、例えば液晶パネルなどの表示画面を有し、静止画像や動画像やテキスト(文字)など各種画像を表示する。特に、表示部120は、車両が車載器を搭載しているか否かの監視を行う場所を決定するための情報を表示する。
通行程度情報生成部191は、監視実施条件候補の示す条件における、監視を実施すべき車両の通行の程度を示す通行程度情報を、車両監視情報及びトリップデータに基づいて生成する。監視実施条件候補が監視場所である場合には、監視実施条件候補を示す各監視場所を監視実施条件として、通行程度情報は、当該監視場所を、監視を実施すべき車両がどの程度通行しているかの程度を示すものとなる。また、監視実施条件候補が監視時間である場合には、監視実施条件候補を示す監視時間を監視実施条件として、通行程度情報は、当該監視時間に、監視を実施すべき車両がどの程度通行しているかの程度を示すものとなる。監視実施条件候補が監視場所及び監視時間である場合には、監視実施条件候補を示す監視場所及び監視時間の各組み合わせを監視実施条件として、通行程度情報は、当該監視場所及び監視時間の組み合わせにおいて、監視を実施すべき車両がどの程度通行しているかの程度を示すものとなる。
より具体的には、通行程度情報生成部191は、通信部110が取得する車両監視情報及びトリップデータに基づいて、監視実施条件候補を通過した車両によって当該監視実施条件候補に与えられるスコアを算出する。本実施形態では、このスコアが高いほど、ある監視実施条件候補、すなわち、ある監視場所や監視時間が、不正車両の監視に適していることを示す。
図4は、車両の走行経路の例を示す説明図である。同図において、線L11は、ある車両の走行経路を示す。この走行経路は、トリップデータにて示される。また、点P11、P13は、それぞれ監視実施条件候補として記憶されている監視場所を示す。ここで、点P11は、実際に監視用サブシステム400により車両の監視が行われたポイントとする。点P11が車両の監視が行われたポイントであるとの情報は、点P11で監視を行った監視用サブシステム400における監視結果に基づいて課金用サーバ200から通信部110に送信された車両監視情報に基づいて取得される。また、点P13は、監視実施条件候補であるものの、線L11を車両が走行した時点で車両の監視が行われておらず今後監視場所の候補となるポイントとする。また、点P12は、課金が行われる課金ポイントを示す。点P12で行われた課金に関する情報は、車載器310との通信により生成されて課金用サーバ200から通信部110に送信された課金情報に基づいて取得される。
図5の例において、通行程度情報生成部191は、線L21を走行する車両によるスコアと、線L22を走行する車両によるスコアとを演算する。すなわち、通行程度情報生成部191は、まず、線L21を走行する車両について、課金ポイントP21における課金額からスコアを演算する。さらに、通行程度情報生成部191は、線L22を走行する車両について、課金ポイントP22における課金額からスコアを演算する。そして、通行程度情報生成部191は、監視場所P23のスコアとして、当該監視場所P23を通過する線L11及線L12のそれぞれを走行する車両のスコアを合計したものを算出する。このように、通行程度情報生成部191は、監視場所別に、当該監視場所を通過する車両ごとにスコアを算出し、これらスコアを合計して通行程度情報を生成する。
なお、通行程度情報生成部191が、通行程度情報として、監視を実施すべき車両の通行の程度を示すことになる監視実施条件となる監視場所ごとのスコアを、監視場所と対応付けて記憶させるようにして地図情報を生成するようにしてもよい。
次に、図6を参照して監視計画評価用サーバ装置100の動作について説明する。
図6は、監視計画評価用サーバ装置100が監視実施条件候補である監視場所の複数の候補から少なくとも一つを選択する処理手順の例を示すフローチャートである。監視計画評価用サーバ装置100は、例えば、監視実施条件候補情報の選択を指示するユーザ操作が行われると、同図の処理を行う。
図6の処理において、通信部110は、トリップデータと課金情報とを課金用サーバ装置200から取得する(ステップS101)。
次に、通行程度情報生成部191は、監視実施条件候補情報に示される監視場所と、トリップデータとを、監視場所の位置に基づいて対応付ける(ステップS103)。これにより、トリップデータに示される走行において、監視場所を通過した場所やタイミングを把握可能になる。
次に通行程度情報生成部191は、ステップS104で算出したスコアを監視場所別に合計して、各監視場所のスコアを通行程度情報として算出する(ステップS105)。
そして、表示部120が、ステップS106での選択結果を表示する(ステップS107)。
その後、図6の処理を終了する。
これにより、自動課金システム1の運用者は、候補選択部192が選択した監視実施条件候補となる監視場所及び監視時刻の少なくとも一方からなる候補を監視するよう監視用サブシステム400を設置して、車載器310を搭載していない車両や不適正な車載器310を搭載している車両などの不正が行われた車両の検出を効率よく行うことができる。
これにより、自動課金システム1の運用者は、車載器310を搭載していない車両の検出を効率よく行うことができると予想される地点を地図で確認しながら、監視を行う場所や時間を決定することができる。
これにより、通行程度情報生成部191は、車両が最後に監視されてから、抽出された監視実施条件候補を車両が通過するまでの時間間隔、走行距離及び課金額の少なくとも一つに応じて異なる程度を示す通行程度情報を生成することができる。このため、監視が行われてからの時間が経過し、長い距離を走行し、または、高額の課金が行われている車両が多く通行しているほど、該当する監視実施条件候補が示す条件を、監視を実施すべき車両が通行している条件であると評価することができ、監視実施条件を決定する際に上記時間間隔、走行距離、課金額を考慮することができる。
これにより、通行程度情報生成部191は、高額の課金逃れを防止または検出するための監視に適した場所または時刻を提示することができる。このため、例えば自動課金システムの運用者は、当該場所または時刻にて監視を行うことで、高額の課金逃れを防止または検出するための監視を効率よく行うことができる。

また、本発明は、車両の監視場所及び監視時刻の少なくとも一方を示す監視実施条件情報と、当該監視場所または監視時刻にて監視対象となった車両の情報とを含み、車両の監視結果を示す車両監視情報を取得する車両監視情報取得ステップと、複数の車両について、各車両の移動に関する車両移動情報を取得する移動情報取得ステップと、車両を監視する場所及び時刻の少なくとも一方からなる監視実施条件候補の示す条件における、監視を実施すべき車両の通行の程度を示す通行程度情報を、前記車両移動情報と前記車両監視情報とに基づいて生成する通行程度情報生成ステップと、を備える、監視計画の評価方法に関する。
