- Expand the deployment of intelligent traffic signal control systems around freeway and expressway ramps. Through simulated traffic environments and reinforcement learning-based AI control strategies, signal timing plans are automatically adjusted in real time to alleviate roadway congestion.
- Intelligent traffic control applications have been implemented across the surrounding road networks of Nanzih Industrial Park and the Kaohsiung Interchange on National Freeway No. 1, including the 367A ramps at Jianguo 1st Road and the 367B ramps at Jhongjheng 1st Road. The project includes the deployment of roadside detection equipment, as well as the upgrading and optimization of traffic signal controllers. A traffic monitoring system has also been established through the application of intelligent transportation technologies. Six months after commissioning, average travel-time performance on roads surrounding Nanzih Industrial Park improved by 7–9%, while average peak-period travel-time performance on roads surrounding the Jhongjheng and Jianguo interchanges improved by 12–15%. From 2025 to 2026, intelligent traffic signal control will be introduced along Provincial Highway No. 1 between Dajhong Road and Jianggong Road, as well as along Jhonghua Road, Cueihua Road, and the dedicated container truck route serving the Port of Kaohsiung. Continuous AI model training and system calibration based on traffic flow conditions will further enhance real-time corridor-wide monitoring and operational management procedures.
- The Bureau’s “Integration of AI and Dynamic Traffic Signal Technologies—Kaohsiung Metropolitan Area Smart Traffic Signal Implementation Program” received the “2025 Intelligent Transportation Industry Innovation Award” from the Intelligent Transportation Society of Taiwan. This recognition affirms Kaohsiung’s sustained investment and technological innovation in intelligent transportation and represents an important milestone in the city’s advancement toward becoming a smart city.
