One of the most common problems faced by traffic management people is the overspeeding of vehicles. Such vehicles are majorly responsible for road accidents and road rage.
With so many vehicles running on the road, there is a
need for intelligent traffic management, which is a blend of technology
and human resources. Radar Speed Signs are one such development in the field of
ITM or Intelligent Traffic Management which has revolutionized the way traffic
flows.
They are the modern traffic controllers that don't need human
interference and work on radar signals.
As mentioned above one of the most common reasons behind the rising number of road accidents is an overspeeding vehicle. It can result in a life-threatening accident for the one who is driving and for those who are commuting.
To cater to this issue, authorities have taken many
stringent steps but manual efforts are insufficient. There needs to be a
system in place that can automatically guide the driver to slow down the speed
and alarm them in case they are overspeeding.
Radar speed signs, traffic calming devices, or driver feedback signs are a great way to achieve this. Researchers have shown that the radar speed signs have been able to cut down the speed of overspeeding vehicles around 80% of the time which is a promising figure.
And the best part about these
signs is that they work without any manual interference.
What is a Radar Speed Sign?
Radar Speed Signs are communicative signs which are illuminated with LED
which is installed on board. Owing to their compact size, these are a perfect
replacement for those large and bumpy traffic calming devices. You don’t need
some extra space to keep them or mount them and their small and sleek design
adds to the aesthetic value of the place.
How do the Radar Speed Signs work?
One of the most talked about questions that may also gain your
attention is, how do these signs work? The radar speed signs work on the Doppler
Effect. These signs have been developed in a way that they emit radio waves and are calculated based on the reflected radio waves that come from the passing
vehicle.
The radar speed limit signs measure the time between the sending and receiving of the signals and this time difference is now converted into distance. The process is repeated and the radar speed signs calculate the new distance.
The new distance cannot be the same as the vehicle has moved and
is now closer to the sign. The speed is calculated based on the two different
distance and the speeds that get reflected on the sign.
These devices allow the operator to feed the speed limit of the vehicle,
if the vehicle is going above the speed, it alarms the driver about the
overspeeding.
There is also a provision for mounting the sign on the vehicle which
helps in calculating the speed of the approaching vehicles. You can usually
find it on the police van or cars of traffic authorities.
The radar speed signs are a highly utilitarian product, they not only help the traffic authorities but at the same time, it also helps the driver to maintain the speed limit.
Owing to this, these signs have become a must-have
for places that experience high traffic or are sensitive like schools,
residential societies, hospitals, etc.
How does it impact the people?
The radar speed signs have been found very effective when it comes to traffic control, it helps in defining the speed limit for a specific area. It alarms the driver of the speed limit and also intimates them in case they are overspeeding.
It also informs about the speed of
the approaching vehicle which helps them in managing the speed.
Thus, these signs have become a necessity more than a compulsion. With
the help of these devices, it is sure that we can have an apt management
traffic system which will remove the bottlenecks and streamline the traffic.
