![]() ![]() Please visit Arlington’s Traffic Signal Specification Updates page for the latest information on these requirements. The County has specific requirements regarding traffic signal construction activities. Traffic signals are constantly being replaced as they age beyond their lifespan or as capital improvement or developer projects require. These LEDs modernize the network, reduce overall costs and minimize the environmental impact. We began converting traffic signals to light-emitting diode (LED) technology in the mid-2000s. The federal standards for traffic signal installation are located on the FHWA’s website. Department of Transportation Federal Highway Administration (FHWA) has published the Manual on Uniform Traffic Control Devices, which contains the standard guidelines for all traffic signals in the United States, including Arlington. Installation of traffic signals is preceded by a thorough engineering study. Signals that are installed when no legitimate need exists often generate an increase in vehicle stops, traffic delays, fuel consumption, traffic accidents and non-compliance. They’re usually very effective, but can be inefficient and potentially dangerous to motorists and pedestrians when installed under inappropriate conditions. Traffic signals provide orderly movement of traffic by assigning rights of way at intersecting streets. The Traffic Management Center is supported by a 45-mile fiber optic network system throughout the Countyĭid you know? The Transportation Engineering and Operations Bureau manages approximately 300 signalized intersections in the County, with 180-plus traffic cameras located at critical intersections.

Since it began deploying the new technology last month, ATD is looking into potential tweaks to the system to see if zones needed to be adjusted to better serve response vehicles. What’s the timeline for more traffic signal preemptions to go online? National studies conducted by the Federal Highway Administration have found that a well-working emergency vehicle preemption system can reduce response times between 14% to 50%.
