The “Professional Services Project for the Application of Intelligent Signal Control at Vulnerable Road Sections in Kaohsiung City (FY2023–2024)” extends the scope of the FY2022–2023 program to implement intelligent traffic control applications across the surrounding road network of the Nanzih Industrial Park and the Kaohsiung Interchange of National Freeway No. 1 (including Interchange Ramps 367A Jianguo 1st Road and 367B Jhongjheng 1st Road). In addition to expanding the deployment of intelligent signalized intersections, the project leverages a simulated traffic environment and reinforcement learning–based AI control strategies to automatically and dynamically adjust signal timing in real time, thereby alleviating roadway congestion.
In addition to the planning and installation of roadside detection equipment and the upgrading and optimization of signal controllers, the project introduced smart transportation technologies and completed the monitoring system by the end of December 2024. Following system activation, from its launch through the end of June 2025, average travel time performance on roads surrounding the Nanzih Industrial Park improved by approximately 7–9 percent, while peak-period travel time performance on roads around the Jhongjheng Interchange and Jianguo Interchange improved by approximately 12–15 percent. Going forward, continuous traffic flow–based training and calibration will be conducted to further enhance real-time corridor monitoring and operational management procedures.
Currently, city has established the intelligent signal control at more than 100 intersections.To further enhance system functionality and ensure sustainable development of intelligent signal control, the City Government continues to apply for subsidies from the Ministry of Transportation and Communications to implement the “FY2025–2026 Kaohsiung City Intelligent Signal Control Application Service Program for Vulnerable Road Sections.”
This program will extend dynamic traffic control applications along the Minzu Road section of Provincial Highway No. 1 and the Cuihua Road corridor. Through the deployment of smart transportation technologies—such as AI, intelligent signals, and signal priority measures—the program aims to improve operational efficiency at signalized intersections along connecting roadways, facilitate smoother passage for emergency vehicles, and effectively enhance the level of service for travel to and from national freeways and science parks.
