EE,ECE3 PIC107 Street light that glows showing the road ahead for km only on sensing vehicles or any movement:

Emitting Diode (LED) replaces HID lamps by engaging a programmable microcontroller that controls

intensity by pulse width modulation which enables energy saving during late nights considering low

traffic density. The pulse width becomes very narrow on sensing no movement of vehicles. As the

vehicle forwards, the intensity goes on increasing for few lights ahead and as it passes away the

intensity goes on falling.

automatic traffic light control system based on the traffic density using appropriate system and

hardware. IR sensors across the road used to monitor the length of vehicles blocking the road traffic.

The signals from the IR receivers are fed to the MC to follow the program with the time as desired. 6450
