Everyone has experienced the frustration of waiting at red lights. Much of the delay that motorists experience occurs at signalized intersections while waiting for the light to turn green. Inefficient traffic signal timing results in congestion and delays causing wasted fuel, increased air pollution and wasted time for drivers and their passengers. Delays can be reduced, however, by optimizing the timing of the signals. Many factors affect traffic signal timing and coordination, including traffic volumes and speeds, side street delay and roadway capacity.
The Denver Regional Council of Governments (DRCOG) has produced a brochure titled, “Why is the Signal Always Red?” which details how traffic signal timing is coordinated.
If you believe a particular traffic signal is operating incorrectly or not allowing vehicles to pass through efficiently, please contact the county at 303-271-8461.
When traffic signals are installed under conditions that justify their use, they become valuable devices for traffic control; however, an ill-advised or poorly designed signal is not only annoying, it can be dangerous to pedestrians, cyclists and drivers.
Before a traffic signal is installed, an engineering study must be performed to determine whether the signal is warranted based on the traffic volumes and speeds and available “gaps” in traffic for turning vehicles. As with stop signs, specifications for signals and their placement, along with minimum requirements for their installation and use, are contained in the Manual on Uniform Traffic Control Devices.
Federal and state regulations require that all traffic signal installations follow the guidelines in this manual. A new traffic signal costs between $150,000 and $300,000, depending on the geometrics of the location and type of signal; therefore, its installation must be carefully considered.
The Colorado Department of Transportation has produced a brochure on “Traffic Signals" , which provides some basic information.
To request an intersection evaluation for a potential traffic signal, contact Jefferson County at 303-271-8461.
