This study evaluated the effectiveness of the traffic light system at Bantayan Intersection in Dumaguete City, focusing on its performance and drivers’ perceptions. Specifically, it assessed effectiveness in terms of accuracy, usability, operational performance, and safety perception, and examined the relationship between drivers’ profiles and their perceived effectiveness. A descriptive-correlational research design with a quantitative approach was employed in this study. Data were collected from 100 drivers, including motorcycle, tricycle, and private vehicle drivers, using a structured and validated questionnaire, supported by on-site observations of traffic flow, delay, and queue length. The data were analyzed using descriptive statistics such as frequency, percentage, and weighted mean, and inferential statistics using Spearman’s rho. Results revealed that the traffic light system is generally perceived as high effective, with an overall mean of 4.02, means that the system generally performs well; drivers experience only minor operational concerns particularly in usability, operational performance, and safety perception. Furthermore, no significant relationship was found between drivers’ profiles and their perceived effectiveness, indicating consistent perceptions across different user groups. Despite the positive evaluation, certain aspects such as signal timing, clarity, and visibility require improvement. The study concludes that while the system effectively regulates traffic and enhances safety, further optimization is necessary to improve efficiency and user experience. The findings provide a basis for recommending improvements and support data-driven traffic management decisions. Additionally, the study highlights the importance of continuous monitoring and evaluation of traffic control systems to ensure their long-term effectiveness. It also emphasizes the role of user perception in assessing infrastructure performance, as drivers’ experiences directly influence compliance and safety outcomes.
