Abstract
Due to the heavy traffic in the road many people are suffering. Even though there is traffic signal available atvarious places it is not easy to control the crowd. In order to avoid traffic problem heavily on the road, we designed and developed a system so called as traffic density controller with wireless control. In the block diagram we will be having the components like IR sensor (4) on each side, LCD display, a Microcontroller, RF transmitter and receiver, key pad, 12 LED driver circuits and 12 LED’s. The IR sensors, both the transmitter and the receiver are placed on either side of the road. The IR sensor senses how many vehicles are crossing on the corresponding side. All the sensors send the corresponding output signal to microcontroller. The LCD display is used to indicate the side through which the vehicle has to be passed.
