       Due to the heavy traffic in the road many people are suffering. Even through there is traffic signal available at various places it is not easy to control the crowed.  In order to avoid traffic problem heavily on the road we designed and developed a system so called as traffic controller with wireless control for ambulance and VIP vehicles.

Function:

       In the block diagram we will be having the components like Microcontroller, RF transmitter and receiver, key pad driver circuit, motor and 12 LED’s.

       The microcontroller controls the traffic signal automatically, which road side led to be glow and order of the road to be give a signal, these are all programmer and embedded into chip. Microcontroller delivers the corresponding signal to LED driver circuits. The LED driver circuit enables the LED to display for particular time depends on road.

       When this type of system is followed, we are sure that we can control the traffic to cretin to extent cretin to extent. From the system we can free up the traffic in the ambulance traveling road by wireless. There is a key pad connected remotely to control that each key present in that the corresponding road will be free up and other roads are blocked and corresponding road speed break down. Also this is implemented for VIP vehicles. After they are crossing the traffic signal then signal will be move on to regular traffic signal control work and speed break up.

      That key pad connected through wireless, using RF transmission and reception we communicate each other. Where encoder is used at transmission end, decoder is used in receiver end for data getting.
