Traffic Signal Upgrades

About the Project

Many of the existing traffic signals in the County have exceeded their intended service life. This project includes the reconstruction of outdated traffic signals to meet current Federal and County standards and specifications. Signal upgrade projects implement new technologies such as accessible pushbutton stations, CCTV for monitoring, video detection, and improved intersection lighting to improve safety, efficiency, and accessibility for all modes of travel.

Transportation Engineers use a variety of methods to prioritize signal upgrade locations, including the type of signal, age of the infrastructure, and the type of roadway facilities impacted. Each signal upgrade requires a design phase and a construction phase.


This project is funded by a variety of sources including County funds, Northern Virginia Transportation Authority (NVTA) funds, and other sources of revenue. The project is locally administered by Arlington County.
