Density Based Traffic Control Techniques-A Review

Abstract

In modern days with the tremendous rise of vehicle numbers on the roadways, traffic jams have been found a massive problem. In the current scenario we can't say that traffic jam is occurring mainly in urban areas, in rural area also traffic jams are increasing. These traffic jams are behind problems like air pollution, noise pollution or delay in time. These traffic jams can't be resolved by only deploying traffic lights in all cities because these lights have fixed intervals of time between red and green lights. Keeping this in mind many attempts were done to change the time interval according to the density of vehicles on the road. This paper summarizes different techniques for traffic management and control systems that can be used for the improvement of the current system.
