SOON , DELHI WILL have smart traffic signals that will measure traffic pressure on stretch and change signals on it accordingly .Traffic police will study its effectiveness during peak hours.
Police will soon issue tenders for installing the system at various spots in the capital including India Gate, Con naught place and Nilson Mandela Marg .
Under this system , the smart traffic signals will have remote sensors which will communicate with other nearby signals to control the traffic flow at a particular intersection.
At present , traffic signals are controlled through preset timing system which at times, results in pileups during peak hours or induce drivers to skip signals during lean hours.
Every time there is a jam at a particular crossing , some one goes and analyzes the pressure of vehicles and adjust the signals' times manually.The real problem arises when one of them breaks down.The entire system
must be shut down until the signal is repaired.But under the smart signalling system, if one signal breaks down , the other will keep functioning because each one works independently .What's more , police at control rooms can identify a faulty signal instantly, if one of them breaks down.The smart signals with independent power systems have inbuilt antennas and sensors that relay a change of traffic light to the next post ,which , in turn respond automatically.
In case of a road , which has signals arranged in close succession , a driver must stop at every crossing as timing of all signals can not be synchronized due to heavy traffic pressure on connecting roads.But under the new system if there is one car waiting at the signal when connecting roads are empty, it will turn green ,a traffic official said.

Benefits of smart signals -
- These are armed with remote sensors that automatically regulate signal cycles depending upon the traffic volume.
- These signals don't have wires, so there is no chance of malfunction due to cable damage, which is often the case with regular signals.
- They have their own power backup in the form of inverters or solar batteries .
- These without charger switch off during power cuts, so traffic goes unregulated or some one has to do it manually.If one signal is affected ,all connected signals shut down.
- Wire often get damaged, mostly due to patchy civic work.
- These are timed manually and traffic volume is not taken into account .Thus ,there are snarls during peak hours and jaywalkers on the road.
