高度デマンド信号制御Ⅱ方式の国道463号線への適用について

摘要

本稿では，国道463号線の実道調査結果に基づいて，信号制御評価用シミュレータを拡張した上，高度デマンド信号制御Ⅱ 方式（Advanced Demand Signals-Ⅱ Scheme；ADS-Ⅱ 方式）の性能評価を行っている．まず国道463号線の一部区間のモデル化とシミュレーションに用いるデータ取得のために実道調査を行う．つぎに調査データに基づき国道463号線の道路構造と系統制御方式をモデル化し，従来の評価用シミュレータに導入する．さらに評価用シミュレータを用いて国道463号線の系統制御方式とADS-Ⅱ 方式の性能比較を行い，ADS-Ⅱ 方式が系統制御方式に比べ，一人当たりの平均アイドリング時間が午前4時台（閑散時に相当）では約70％，午前7時台（混雑時に相当）では約60％削減されることを示している．%This paper describes extension of the conventional simulator for evaluation based on results of the actual road survey on route 463 in Japan and performance evaluation of the advanced demand signals II (ADS-Ⅱ) scheme. Firstly, the survey of a part of route 463 is carried out to model this zone and to collect data for simulation. Secondly, after the road structure and the coordinated traffic control scheme of route 463 are modeled based on the survey data, these models are introduced to the conventional simulator. Finally, using this simulator, the performance of the ADS-Ⅱ schemes is compared with that of the coordinated traffic control scheme on route 463. Results show that the average idling time per person of the ADS-Ⅱ schemes and that of the coordinated control scheme approximately are reduced by 70% at period of 4:00 a.m. (off-hour) and by 60% at period of 7:00 a.m. (rush-hour), respectively.
