Density Based Traffic Controller System

Density Based Traffic Controller System

Density based traffic lights system using 8051 microcontroller

Traffic congestion is a severe problem in many major cities across the world and it has become nightmare for the commuters in these cities. Conventional traffic light system is based on fixed time concept allotted to each side of the junction which cannot be varied as per varying traffic density Junction timings allotted are fixed. Due to the heavy traffic in the road many people’s are suffering and also because of large time delays between traffic lights.

So, in order to rectify this problem, we will go for density based traffic lights system designed to develop a density based dynamic traffic signal system where the signal timing changes automatically on sensing the traffic density at the junction.

Block diagram:-

 

In this system, we will use IR sensors to measure the traffic density which are interfaced to the microcontroller. We have to arrange the IR transmitter and IR receiver for each road in particular manner; these sensors sense that the traffic density on that particular road is high or low, and sends the signal to the microcontroller then according to the traffic density microcontroller will controls the traffic signal system.

If the traffic density is high or low on one way then the system will analyses the traffic and according to that it will increased or decreased the time of signal lights. Which will help to reduce the traffic jam problems?
