Abstracts: Transportation is one of the prevalent issues in the modern world. We all know, with the world, India also a very swift growing nation. Amount of number of vehicles increased very rapidly in last few decades. Roads are also developed in massive amount but vehicles are still counting and counting. So, increment of the number of roads is not only a way out of downy passing of vehicles i.e. it needs some sophisticated transportation system. As an example, a traffic problem at intersection at urban city . Although it can be solved by traffic signal design. The conflicts arising from movements of traffic in different directions is solved by time sharing principle. The advantages of traffic signal includes an orderly movement of traffic, an increased capacity of the intersection and requires only simple geometric design. However the disadvantages of the signalized intersection are it affects larger stopped delays, and the design requires complex considerations. Although the overall delay may be lesser than a rotary for a high volume, a user is more concerned about the delay.
