Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck); other vehicle (e.g., moped, bicycle); and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road.
One of the main problems in our city’s is traffic, this project proposed new solution to traffic control. The main design accept of this project is to control the traffic automatically and adding human inelegancy to that automatic controller.
“Four-way” intersection is the most common configuration for roads that cross each other, and the most basic type. If signals do not control a 4-way intersection, signs or other features are typically used to control movements and make clear priorities.
The main draw back of normal automatic traffic light controller is it gives green signals to different directions with some constant time delay. If we consider a junction, the traffic from all directions may not be same and density will change as per time. If controller is not considered this traffic density then what happened, traffic will become more and more in one side and another side even though there is no vehicles controller shows green light. Through our project we can avoid this problem.
In this project we are going to use IR communication to analyze traffic density. IR signals from IR receiver are given to microcontroller and microcontroller gives appropriate result according to traffic. For better result we are going to use some bunch of IR transmitters and IR receivers in all directions. When there is a more traffic in one side more no. of IR receivers will not get the signals and result will compare with all other directions and microcontroller gives green signals at one side where more no of IR receivers will not get the signals.
For IR communication we are using an IR transmitter and IR receiver. Here IR LED will acts as a transmitter. As we know microcontroller having inbuilt I/O ports and we are interfacing IR receivers to those I/O ports. For controlling of traffic we are using red, green and yellow color LED’s. These LED’s are connected to different I/O ports of microcontroller. When there is a more traffic microcontroller gives signal to green LED and it will glow. So by using this project we can control the traffic automatically like a human being.
