Kaohsiung Implements 'Summer Time' Signal Plan to Reduce Sun Exposure for Commuters

The Kaohsiung City Transportation Bureau announced on the 25th that it will implement a 'Summer Time' project. From now through August, the bureau will flexibly shorten red light durations on selected arterial roads during specific hours to reduce the time commuters spend waiting in the sun, thereby mitigating discomfort caused by summer heat.

In a press release issued today, the bureau noted that Kaohsiung experiences significant urban heat island effects, making motorcyclists and pedestrians vulnerable to prolonged sun exposure while waiting at intersections. The city's 'Summer Time' project utilizes dynamic smart signal control mechanisms to flexibly reduce red light durations during peak heat hours.

According to the bureau, the project uses traffic flow detectors (VD) and big data analysis of vehicle trajectories to prioritize the optimization of arterial corridors with signal cycles exceeding 200 seconds and interconnected control features. The plan will be implemented daily from 9:00 AM to 4:30 PM, starting recently and continuing through August.

The Transportation Bureau explained that 'Summer Time' is not merely an adjustment of individual intersection timings but an optimization of entire corridors via a 'Smart Signal Control System.' This approach aims to shorten waiting times while maintaining coordinated traffic flow on arterial roads, preventing negative impacts on overall traffic efficiency or localized congestion.

During the implementation period, the city's Traffic Control Center will conduct round-the-clock monitoring and make rolling adjustments based on real-time traffic flow. The bureau emphasized that this project balances 'human-centric transportation' with 'efficiency management.' Looking ahead, the bureau plans to integrate meteorological data and AI predictive models to develop more precise and real-time signal control strategies.
