Traffic Signal Lights Control System

Traffic congestion is a severe problem in many major cities across the world and it has become nightmare for the commuters in these cities. One of the oldest ways of handling traffic was having a traffic policeman deployed at each junction and manually controls the inflow of traffic through hand signaling. However this was quite cumbersome and then came the need for a different type of control – using Traffic signals.

So, in order to rectify this problem, we will go for traffic signal lights control system designed where traffic light is control by changing single automatically at specified range of time interval to provide sophisticated control and coordination to confirm that traffic moves as smoothly and safely as possible.

Block diagram:

Here we implemented Traffic light control system using 8051 microcontroller and  three LED’s to perform the traffic lights operations and get automatically switched on and off by making the corresponding port pins of the microcontroller high.

The LED’s was connected in a common anode mode so that the Microcontroller was used as a sink here.

The Red colour was made to flash for 10 secondsand the other lights remains OFF, and after sometime, the changeover traffic light control from red to yellow takes place by making the succeeding change for glowing of green LEDfor five seconds each. This process continues as a cycle.
