A Review on Road Traffic Monitoring System

Road network of a city is an important mean for overall development. It is the key factor for city authority to control the traffic in the city. With the increase in the number of vehicles day by day traffic congestion is a significant challenge. The main reason is the increase in the population of metro cities, urbanization and economical development of the country that subsequently led to the increased demand for vehicular travel. One method to overcome the traffic problem is to develop an intelligent traffic control system which is based on the measurement of traffic density on the road using real time video and image processing techniques. In this paper we reviewed the algorithm to determine the number of vehicles on the road. The density counting algorithm works by comparing the real time frame of live video by the reference image and by searching vehicles only in the region of interest (i.e. road area). The computed vehicle density can be compared with peak value of the traffic in order to control the traffic smartly.
