臺北市智慧號誌建置之研究

The Study of Intelligent Traffic Signals Control in Taipei City

臺北市自2019年開始於重點區域路廊與部分路口導入智慧號誌，並結合AI辨識技術進行行人與行車之物件偵測，成效斐然，行車時間約可改善7-15%，路口延滯減少10-20%，並且每年節能減碳成效約可帶來近6千萬元之經濟效益。有鑑於此，臺北市於2023-2025年持續擴大辦理智慧號誌建置作業，利用AI影像辨識即時蒐集道路車流資訊，因應車流變化，迅速演算號誌時制計畫，達成號誌時制即時控制，在有限的道路容量下，提升車流紓解效率，提供民眾更便捷、安全、舒適的通行環境。

Since 2019, Taipei has established an intelligent traffic signals system on main corridors and critical nodes combined with AI image recognition technology that detects pedestrians and vehicular objects. The results have been remarkable: travel time was reduced by 7-15%, and intersection delay was decreased by 10-20%. It is estimated to be able to save more than 60 million NT dollars annually for the monetization benefit of energy saving and carbon reduction. To continue the success of intelligent traffic signals, the system will expand to a larger scope in 2023-2025. Applying AI image recognition to collect real-time traffic flow information, adapting to changes in traffic patterns, swiftly computing signal timing plans, and achieving real-time signal control and enhancing traffic flow relief efficiency within limited road capacity, providing the public with a more convenient, safe, and comfortable commuting environment.
