Abstract

Traffic congestion is a severe problem in many major cities across the world and it has become a major issue for the commuters in all the cities. The delay of respective light is hardcoded in the traffic light and it is not dependent on traffic. This creates unnecessary waiting for drivers, which could not be endurable in every case, as being in time, is important to everyone. Density, speed, and flow are the three critical parameters for road traffic analysis. As the number of road Users constantly increases, and resources provided by current infrastructures are limited, the control of traffic has become a very important issue in the present. Also, one of the major problems faced by heavy traffic is by Ambulances. The aim of this project is to solve traffic congestion which is a severe problem in many modern cities all over the world. The traffic density is controlled using a microcontroller. This the system contains IR transmitter and IR receiver which are mounted on either side of roads respectively. The IR system gets activated whenever any vehicle passes on a road between IR transmitter and IR receiver. The objective for usage of IR sensor is to detect obstacles. The microcontroller controls the IR system and counts the number of vehicles passing on the road. The microcontroller also stores vehicles count in its memory. Based on different vehicles count, the microcontroller takes the decision and updates the traffic light delays as a result. It calculates the glowing time of LED according to the density of vehicles. If the density is more, LED will glow for a longer time than normal average and vice versa. It means that the timing of the traffic lights is set according to the density of the vehicles. This helps in the reduction of the traffic congestion and it has a scope for further expansion in the future. By measuring the traffic lined up on a particular road the signal timings are adjusted to let that particular way clear out and then the next populated one. It also consists of an emergency override that allows traffic authorities to remotely let go a particular signal in case an ambulance or important vehicle arrives on that way.
