SMART TRAFFIC CONTROLLING SYSTEM WITH AMBULANCE DETECTOR

– The project is aimed at designing a density based dynamic traffic signal system; the timing of the signal will change automatically on sensing the traffic density at any junction. Traffic congestion is a severe problem in most cities across the world and therefore it is time to shift more manual mode or fixed timer mode to an automated system with decision making capabilities. higher traffic density at one side of the junction demands longer green time as compared to standard allotted time. We therefore propose here a mechanism in which the time period of green light and red light is assigned on the basis of the density of the traffic present at that time. This is achieved by using PIR (proximity Infrared sensors). Once the density is calculated, the glowing time of green light is assigned by the help of the microcontroller (Arduino). The sensors which are present on sides of the road will detect the presence of the vehicles and send the information to the microcontroller (Arduino) where it will decide how long a flank will be open or when to change over the signal lights. In this paper we provide the above information with a block diagram and flowchart.
