桃園市政府交通局7月起在八德區大湳交流道周邊14處路口,導入「AI智慧號誌控制系統」,透過大數據即時調配路口綠燈時間,讓上午7點到9點尖峰時段平均旅行時間縮短46秒,下午5點到晚間7點尖峰時段則重點改善下交流道往和平路、和強路方向路段,平均旅行時間縮短了28秒。
交通局長張新福說,為解決大湳交流道周邊長期以來的交通壅塞瓶頸問題,交通局導入AI智慧號誌控制系統,首度將國道2號進、出入口匝道的即時車流納入模型運算,經過8個月的數據蒐集與深度學習調校,已達到整體場域「平均旅行時間減少6%」、「路口停等延滯降低5%」等效果,預估每年可減少33公噸二氧化碳排放。
大湳交流道周邊動線複雜,傳統定時號誌已無法即時因應車流與匝道回堵,張新福說明,導入AI智慧號誌控制系統,可讓號誌具備「即時看懂車流、動態調整秒數」能力,並透過大數據即時調配路口綠燈時間,上下班尖峰時段都已展現成效,以上午尖峰時段為例,整體平均旅行時間縮短了46秒,民眾上班通勤時間有感減少14.1%,有效發揮快速疏導車流的功能。
過去關於大湳交流道壅塞的「市政信箱」陳情案件,平均1個月約16件,AI智慧號誌控制系統上線後,平均1個月陳情案件降為4件、降幅約7成5,張新福說,市府已爭取到交通部智慧運輸系統發展建設計畫補助,預計明年能將AI智慧號誌控制系統導入南崁交流道春日路廊,全力改善春日路上下午尖峰的壅塞問題。
