The Traffic & Signal Unit is responsible for the maintenance and repair of nearly 300 electrically operated traffic signals, as well as pavement markings and signs on 180 miles (425 lane miles) of roadway within the County network.

Traffic Signal Maintenance and Repair

The Unit seeks to maintain safe travel for residents of Mercer County with continued upgrades and positive maintenance of signs, pavement markings and traffic signals.  This is accomplished by providing the latest materials, equipment, technology and standards.  We also make this possible by using good maintenance practices and professional engineering judgment. 

Pavement Markings

Pavement markings provide important information while allowing minimal diversion of attention to the roadway.  Pavement markings can enhance roadway delineation with the addition of audible and tactile features such as bars, differential surface profiles, raised pavement markers, or other devices intended to alert drivers that delineation on the roadway is being traversed.  Thermoplastic pavement marking durability is affected by material characteristics, traffic volumes, weather and location.  The Unit inspects all pavement markings along county-maintained routes and re-applies markings when warranted and reconfigures markings for better clarity.

Roadside Guide, Regulatory and Warning Signs

Roadside traffic signs along the 180 linear miles of County Routes are routinely inspected.  Damaged signs are fabricated and replaced, when warranted and in the respond to emergency service calls.  In addition, the signage upgrades are undertaken to improve safety and wayfaring.

Emergency Service Calls

The Unit responds to emergency calls from local municipal police and public works departments, as well as residents.
