A Speed Limit Sign is an interactive sign, generally constructed of a series of LEDs, that displays vehicle speed as motorists approach. The purpose of radar speed signs is to slow cars down by making drivers aware when they are driving at unsafe speeds. They are used as a traffic calming device in addition to or instead of physical devices such as speed humps, speed cushions, speed tables, and speed bumps.
The devices have been referred to by a wide variety of names, a partial list of which follows: driver feedback sign, radar signs, Vehicle Activated Sign (UK), changeable message sign, Your Speed sign, radar feedback sign, speed radar sign, radar speed display, speed feedback sign, traffic calming sign, speed display board, dynamic speed display (DSDS) or variable message sign.
Application
Radar speed signs are often used in school zones, sometimes in conjunction with Safe Routes to School programs, in construction zones, or on busy residential roads. Some college and corporate campuses use radar speed signs to slow traffic as well. Many plants are using these signs to monitor forklifts and other type trucks. There are steps to placing a radar speed sign.
Speed display signs are sometimes used in conjunction with physical traffic calming solutions. They are also used on streets that cities do not want to put physical measures on either because of snow concerns or traffic volume. Often, cities will use these signs to test streets to ***ermine the need for further traffic calming.
Features and Sign Types
Signs are available in a range of costs with a variety of different features. Manufacturers of radar speed signs abound, ranging in style and features from a basic inexpensive sign to more sophisticated signs with myriad features to help analyze data and improve results. Pole mounted signs that combine speed display with variable message capability are often used in school zones, eliminating the trailer's "footprint".
Standard signs have stationary block letters that display the words "your speed". |
