Radar speed signs display the variable speeds of the vehicles plying on the road in real-time. They are used primarily to control the faster moving vehicles and help the driver slow down the vehicle due to the road conditions and the legally permissible limits. These electronic speed signs contain LEDs with a RADAR device just like the one they use in aircraft and submarines. The RADAR sends and receives signals to calculate the speed of the approaching vehicle. It provides an easy way to calm down the vehicle instead of using speed breakers or other physical intrusions.
The features
Radar speed signs with specific features favored by the industry and enhance their usability under all kinds of weather conditions. These electronic speed signs are also highly customizable as per the client’s need and can be used on any freeways, local, and community roads equally well. These devices are robust machines that are dust and moisture-proof and work equally well in all climates and weather. They provide a minimum response time that ensures enhanced real-time performance. They also have an adjustable pixel pitch to provide better visibility, with a high-resolution camera to provide a direct live feed to the command center.
Types of speed signs
Most of the radar speed signs are portable in their own capacity for easy installation and moving to new locations as per the need. They come in various forms and designs, and some can be modified to meet special requirements. The most commonly found electronic speed signs are solar, portable, pole-mounted, and trailer-mounted. The solar speed signs have a solar panel that allows them the flexibility to be used at places with no normal power supply. The information they collect on the traffic is shared through a GPRS device that is also powered by the solar panel.
The portable radar speed signs can be installed or moved quickly to a new location as per the enforcement agencies’ need. These are usually temporary speed signs at a site that are powered by a rechargeable battery unit. However, the pole-mounted electronic speed signs are the most common type that we come across on any roads, school buildings, places with high traffic, etc. They have an external power source with a wired or wireless connectivity to the command center. The trailer-mounted ones may use a rechargeable battery or be plugged into the trailer for their power requirements.
Speed sign variants
There are different variants of these electronic speed signs as per their on-site usage requirements. All of them can be of many different types, as mentioned above. The street series radar speed signs are specifically designed for the dynamic moving traffic on the road. They are highly accurate devices that can handle a lot of vehicles in less time. The speed signs used in work zone areas are highly dust resistant and visible from a distance easily. In comparison, the portable ones are very durable and robust, with the ability to be used in remote places with no power supply.
