Which type of maintenance would include regularly scheduled inspections of traffic signals?

Preventative maintenance is focused on regularly scheduled inspections and servicing of traffic signals to ensure their proper operation and prolong their lifespan. This proactive approach helps identify potential issues before they escalate into more significant problems, reducing the likelihood of unexpected failures. By conducting inspections at set intervals, technicians can perform necessary adjustments, clean components, and replace worn-out parts, which ultimately contributes to the overall reliability and safety of the traffic signal system.

In the context of traffic management, preventative maintenance is essential for maintaining optimal performance levels, minimizing downtime, and ensuring that signals function when needed, especially in high-traffic areas. This type of maintenance plays a crucial role in overall traffic safety and efficiency, allowing municipalities to manage their infrastructures effectively.

The other types of maintenance mentioned serve different purposes. Emergency maintenance addresses unexpected failures that require immediate response. Reactive maintenance is for repairing components after they have failed. Corrective maintenance deals with fixing problems that have been identified, which may not be scheduled but rather based on the need for repairs. These approaches do not inherently involve regular inspections or proactive care as preventative maintenance does.
