How can technicians ensure they are maximizing the performance of traffic lights?

Maximizing the performance of traffic lights primarily involves frequent testing and calibrating signals to ensure they are functioning as intended. Regular testing and calibration help identify any issues with timing, detection, and visibility that may hinder a signal's effectiveness. This practice allows technicians to adjust the signal programming based on current traffic patterns, which can change over time due to factors such as increased vehicle volume or construction activities.

Furthermore, ensuring that signals operate optimally contributes to improved traffic flow, reduced congestion, and enhanced safety for both drivers and pedestrians. In contrast to this approach, adjusting the height of the lights may not directly impact their operational performance or effectiveness. Using outdated technology can lead to inefficiencies and an inability to adapt to new traffic management needs. Regular maintenance is crucial for preventing breakdowns, but neglecting it would lead to deterioration in performance rather than enhancement.
