Actually this is remote traffic monitoring and control system in which a police man can control the flow of traffic from a remote location through his computer. He can generate all three traffic signals (red, green & yellow) on a click of mouse only. Also he can divert the flow of traffic by monitoring it on his computer screen through camera.
The program written in VC++ controls the traffic flow in both the manners automatic and manually. In automatic mode traffic flow is controlled by predetermined time periods and in manual mode a police man can open or close any lane depending on the traffic density on each lane. Means if on one lane traffic is much more than any other then that lane is open till any other lane has a greater traffic density.
One more added feature is alarm system. Whenever any driver wants to drive out in red light the laser beam will be interrupted and it will ring an alarm in police station.
Note:- complete project is developed by two students Patel Bhavin and Tandel Jiten of 4th EC from Dr. J. N. Meha Govt. Polytechnic, Amreli under my guidance.
There are two sections of the project (1) Hardware section (2) software section
Hardware section is to switch ON/OFF Red, Green & Blue LEDs of all four lanes. Depending upon the input code given to the circuit by computer program, it will ON or OFF particular LED.
The software section just gives the proper code to the circuit depending upon the user command like to open lane 1 or lane 2 or anything else.
it will be better to understand software codes if we first see the logic behind the hardware circuit.
