Smart Transportation Steering Group
The framework of Taipei Smart City takes “smart government” as the core value, and promotes “smart security”, “smart building”, “smart transportation”, “smart education”, “smart healthcare”, “smart environment”, and “smart economy” to be the blueprint for the future development. In order to achieve it, “1+7 smart city steering groups” were established. The steering group is led by the Department of Transportation, and cooperating with the Department of Information Technology, Taipei Rapid Transit Corporation, and outside experts. It is hoped that the city vision of safe, convenient, shared, and green can be achieved through smart technologies to enhance transport efficiency and minimize environmental impact.
Intelligent Traffic Signals Control Application in Taipei
Taipei City has developed 22 intelligent intersections in 2020, including dynamic control system for congestion improvement and traffic -responsive signal control system for green time efficiency at intersections.
The dynamic control system named PaSO Plus uses real-time traffic data from roadside detectors and compute important traffic parameters in a very short time to send dynamic signal plans to the onsite signals. In this way, the signals could adjust green time in repsonse to the real traffic demand to optimize the traffic flows in the control area and improve corridors travel time. The travel time of the main corridors - Keelung Road and Xinyi Road around Xinyi District CBD has been reduced by 9~17%.
The traffic-responsive signal control system uses AI edge image reconition system and the pedestiran touch button to sense vehicles and pedestrians, and adjust phase split instantly. In this way, the waste time of stopped vehicles on the arterial road can be saved and pedestrian crossing intersections become safer.
