Traffic signals are the most convenient method of controlling traffic in a busy junction. But, we can see that these signals fail to control the traffic effectively when a particular lane has got more traffic than the other lanes.
This situation makes that particular lane more crowdy than the other lanes. If the traffic signals can allot different time slots to different lanes according to the traffic present in each lane, then, this problem can be solved easily.
We, in this project work, intend to measure the traffic density by counting the number of vehicles in each lane and then allot different time slots to different lanes according to the number of vehicles.
Its also difficult for a traffic police to monitor the whole scenario round the clock. So, we use an automated system which counts the number of vehicles in each lane, allots different time slots to different lanes according to the number of vehicles present in each lane.
For automation, we have decided to use a Programmable Logic Controller (PLC). Due to its ruggedness and ease of programming and re programming, PLC is the most suitable controller for the above purpose.
