What are the two types of traffic signal maintenance that are commonly performed?

The two types of traffic signal maintenance that are commonly performed are emergency and scheduled maintenance. Scheduled maintenance focuses on routine inspections and servicing to ensure that traffic signals operate effectively and comply with safety standards. This proactive approach helps to identify potential issues before they become serious problems, ultimately extending the lifespan of the equipment and improving traffic flow.

Emergency maintenance, on the other hand, addresses unforeseen malfunctions or incidents, such as signal outages or damage caused by accidents or severe weather. This type of maintenance is critical for restoring traffic signal functionality quickly to minimize disruptions and enhance road safety. The combination of both types of maintenance ensures that traffic signals are reliable, safe, and efficient, responding to both regular operational needs and unexpected challenges in the field.
