CONTROL OF TRAFFIC USING SMART SIGNALING

CONTROL OF TRAFFIC  USING SMART SIGNALING

PROBLEM SUMMARY:-

 This particular project is designed for the cities with heavy traffic .E.g.: In some cities like Ahmadabad, Surat, Rajkot, Vadodara, etc. the roads are full jammed every time. Most of the time the traffic will at least for 200meters .In this distance the traffics police can’t hear the siren form the ambulance .so he ignores this .Then the ambulance has to wait till the traffic is left. Some times to leave the traffic it takes at least 30 minutes .So by this time anything can happen to the patient .So this project avoid these disadvantages. According to this project if any ambulance comes near when the ambulance at emergency comes to any traffic post the traffic signals automatically stop the signals and give green signal for this ambulance.

Detailed Description of Problem:-

When the ambulance at emergency comes to any traffic post the traffic signals automatically stop the signals and give green signal for this ambulance.

The ambulance carries an RF transmitter and every traffic post will have an RF receiver.

So whenever the ambulance comes near the traffic, the ambulance will transmit a code say “emergency” the receiver will receive this signal and check in the database of the micro controller.

Then it immediately switch off the other signals that is it make all the signals red and later make this particular direction signal green. So by doing this the ambulance can go without any problem.
