IR Based Traffic Density Detection And Signal Adjustment

Download Project Document/Synopsis

Density based traffic control with android override

The project is a traffic signal controller system that reacts to the density of traffic. The time required on changing signals adjusts automatically depending on the density of traffic. Well traffic problems contribute a major problem in many cities and also increase fuel consumption as well as pollution.
Traffic signals operating on fixed signal timing delays do not adjust to the changing traffic density. When the traffic density increase more than a limit at one particular side, it needs a longer green light duration to ease traffic flow.
Our system uses a microcontroller of the 8051 family that is interfaced with IR sensors. These IR sensors are used for line of sight object detection using which the system gets an input of the traffic density. Traffic density is measured as “low, medium and high”.
Based on this density reading the system adjusts and varies the traffic signal duration for that particular way.
This system can also be further enhanced by using multiple such systems across the city and synchronizing them through a network.
