Types of Radar Warning Signs
Portable radar warning signs are equipped with universal wheels at the bottom of the sign, so that it can be moved to the appropriate roadway to identify and measure the speed of vehicles.
There is a photovoltaic device that receives solar energy on the top of the radar warning sign, which can store electricity through solar energy.
A 15-18 foot high resolution LED display is used as the display screen for the radar warning sign. The speed can be clearly seen by a car from 20 meters away.
The larger size and wider pixel pitch of the radar warning sign allows cars at greater distances to clearly see the numbers displayed.
Function of Radar Warning Sign
The radar warning sign reminds the driver of the current speed, so that the driver can control the driving speed.
When the radar warning sign recognizes that there is congestion ahead, it can automatically adjust the maximum speed limit to prevent accidents.
Certain road sections may have construction, accidents and other factors that require radar speed signs to limit the maximum driving speed.
Radar warning signs can record illegal vehicles and report them to the local traffic management department.
Automatic adjustment of screen brightness
There is a light sensor inside the radar warning sign. When strong sunlight is detected, it will automatically increase its own brightness to ensure that it is clearly visible during the day.
Similarly, when it is nighttime, the brightness is automatically reduced to ensure that it is not too harsh to view at night.
Flashing Speed Alert
When a vehicle exceeds the current maximum speed limit, the driver is alerted by flashing numbers and colors on the screen. This prevents drivers from being penalized by traffic authorities for speeding.
Maximum speed can be set individually or in a batch
Through the LED control system of the remote server, we can set the maximum speed of single or multiple radar warning signs to better manage the traveling vehicles on the road.
Assisting Law Enforcement in Tracking Suspects
When law enforcement learns that a suspect is fleeing in a car, it can help them to plan in advance how to stop the suspect by paying attention to his/her route and obtaining information about him/her as he/she passes through the radar warning signs.
Application Scenarios for Radar Warning Signs
Most countries in the world have certain requirements on the speed of vehicles traveling on highways. For example, in China, cars are usually required to travel at a maximum speed of no more than 120 kilometers per hour and a minimum speed of no less than 60 kilometers per hour.
If there is construction or an accident ahead, the radar warning sign can also be controlled at 25 kilometers per hour.
Contrary to highways, urban roads usually require cars to travel at a maximum speed of no more than 60 km/h, especially on sidewalks and in school zones, where the speed limit may even be 30 km/h or less.
When we get on the highway from an on-ramp and already get off the highway from an on-ramp, we will come across these radar speed signs, reminding us that we should either increase our speed or slow down.
