Signal synchronization automatically changes when traffic density is detected at the junction. Traffic congestion is a serious problem in many major cities around the world and has become a nightmare for travelers in these cities. The conventional semaphore system is based on the fixed time concept assigned to each side of the joint that can not be varied according to the variable traffic density. The assigned bonding times are fixed. Sometimes a higher traffic density on one side of the junction requires a longer green time compared to the standard allotted time. The image captured in the traffic signal is processed and converted into grayscale image, then its threshold is calculated on the basis of which the contour has been drawn to calculate the number of vehicles present in the image.
Today, traffic control becomes a major problem due to the rapid rise of cars and also due to the large delays between traffic lights. Therefore, in order to rectify this problem, we will go for density-based semaphore system. This article explains how to control traffic based on density.
