What are some benefits of traffic signal scheduled maintenance?

Scheduled maintenance of traffic signals plays a crucial role in ensuring their optimal performance and longevity. One of the primary benefits is the reduction in the number of emergency repairs needed. Regular maintenance allows for the identification and rectification of potential issues before they escalate into serious problems that could result in equipment failure or hazardous situations at intersections. By addressing minor discrepancies during scheduled check-ups, technicians can prevent costly emergency repairs that might occur due to neglect, which would also mean fewer disruptions to traffic flow and improved safety for both drivers and pedestrians.

In contrast, the other options do not align with the objectives of scheduled maintenance. Increased travel times and higher emissions indicate operational inefficiencies, which maintenance is intended to mitigate. Enhanced fuel consumption would typically result from malfunctioning traffic signals causing delays, not from their proper maintenance. Thus, the practice of maintaining traffic signals on a schedule directly contributes to smoother traffic operations and a more environmentally friendly outcome.
