The project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection.
The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.
The system is embedded with sensors that automatically detect lanes with traffic and lanes that are traffic free. Based on these input from the sensors the controlling system makes its decision. Nevertheless, the system also comes with automatic street light controller that automatically switches on the street lights once there is darkness while offing the lights once the weather is bright. Further more, the warning light blinks before transitioning from one state to another (e.g from stop to ready or go).
In this design we have implored the use of both hardware and software to bring about the entire project. The hardware components are solely coordinated by the AT89S51 micro controller chip while the programming language is used to program the chip.
