Circulartraffic signwith a blue background meaning

These systems continuously monitor the status of the signals, collect traffic flow information and support signal-timing operations and changes, such as time of day and congestion levels.

This sign is supplied CE marked and is made from road grade materials, it has a long lifespan and will stand the test of time.

These guidelines help identify potential locations for signals, but each location is reviewed before a signal is installed.

Fixed-time traffic signals assign the green light to the different approaches of an intersection for a predetermined amount of time. Some of them also can be set to change to different green times during peak traffic hours. These signals can be found in urban areas where traffic movements are fairly predictable.

They let motorists take turns moving through busy intersections and can enhance safety. But, in the wrong location, a traffic signal can actually contribute to accidents and congestion. A potential accident exists every time a vehicle is stopped on the highway.

The department follows federal guidelines that establish minimum conditions under which signal installation should be considered.

VDOT engineers generally recommend a traffic signal be installed when accidents involving vehicles approaching from different directions occur at an abnormally high rate.

Before red light running cameras can be installed at any intersection, a locality must complete an engineering safety analysis for the specific intersection, taking into account the intersection’s accident rate, its red light running violation rate and the difficulty law enforcement officer’s experience in safely apprehending violators among other factors.

We can provide this sign from 450-900mm. Normally this sign is 750mm but is increased to 900mm when it is difficult for drivers to follow the correct route.

Twin rear channels mean the sign face can be clamped in place and will not twist once secured. The clamps are available to supply separately and are not included with the sign face.

New traffic lights you may see are made out of arrays of light emitting diodes (LEDs). These are tiny, purely electronic lights that are energy efficient and have a long life.

The 2007 General Assembly enacted legislation that allows counties, cities and towns to use red light camera enforcement – commonly called photo enforcement. This legislation provides localities the option of installing and operating red light running camera systems.

Certain types of accidents can be reduced in number or severity by the installation of a signal, while other types may not be affected.

None of these statistics take into account the high costs of property damage, medical treatment and productivity losses. Most red-light running crashes are angle or side impact, which tend to be more severe than rear-end crashes.

LEDs are replacing the old-style incandescent bulbs rated at 150 watts. The LED display has a 25-watt rating and generate very little heat, which cuts down on electricity demands.

Nearly every driver has experienced the anxiety of having a light suddenly turn yellow while rapidly approaching an intersection. We all have been caught behind one red light after another on a busy thoroughfare. The Virginia Department of Transportation's job is to find the point where a signal will help more than it will hinder traffic and relieve more congestion than it will cause.

R2 (RA2) Reflectivity makes this sign suitable for use with vehicles and reflects around 32% of the light that hits the surface back to the driver. This material is also called HIP which stands for high intensity prismatic.

This sign is designed to indicate that the only trams or trams and buses are permitted to use the road / tramway ahead. This sign is most commonly placed where a tramway leaves an existing carriageway.

Most cities in the United States are in the process of replacing their incandescent traffic lights with LED displays because they:

Traffic responsive signals change the lights according to the amount of traffic in each direction. These signals use sensors to detect the number of vehicles. They automatically adjust the length of the green light to allow as many vehicles as possible through an intersection before responding to vehicles on another approach.

The number of intersections where a locality is allowed to operate photo enforcement is based on population. The legislation allows no more than one intersection per 10,000 residents.

While not required for intersections located outside of VDOT’s right of way, localities are encouraged to use the same Engineering Safety Analysis Template required for intersections that are located within its right of way.

If you happen upon a traffic light experiencing an outage or covered by snow or debris, treat the traffic light as a stop sign and use extreme caution before proceeding.

The backing of the sign is made from a rigid plastic sandwiched between two skins of aluminium making the sign strong and very durable. As there is no steel it will not rust giving a great lifespan.

In 2010, red-light running resulted in 673 fatalities and an estimated 122,000 injuries nationally. (Insurance Institute for Highway Safety, 2012)

A comprehensive process of how localities submit requests for intersections located within VDOT’s right of way is included in the Red Light running camera (photo enforcement) engineering safety analysis guidelines document.
