We identified Kothavalasa T-Intersection has been arise problems like road accidents, conflicts and congestions. Design elements that are particularly important include the number of lanes provided on each approach and for each movement. These problems can solve by providing an efficient traffic signal control at the intersection for continuous movement of vehicles through the intersection. According to traffic signal, most traffic signal timing plans are designed to minimize vehicle delay based on the volumes seen in the past, not the present. Traffic count studies are to be made to determine the number, movement and classification of vehicles at an intersection. Signal timing is most important which is used to decide green time of the traffic light shall be provided at an intersection and how long the pedestrian walk signal should be provided. By using Highway Capacity Manual (HCM) intersection saturation for identifying periods of time when cycle length could be substantially short. These data is used identify normal flow of the roadway; determine the influence of heavy vehicles or pedestrians on vehicular traffic volume. Webster’s minimum delay cycle length equation overestimates the optimal cycle length compared to the results based on the HCM 2000 method. This is due to the restructuring of the HCM 2000 delay equation as compared to the original Webster’s delay calculation.

INTRODUCTION Traffic engineering is a branch of transportation engineering that uses engineering techniques to achieve the safe and efficient movement of people and goods. It focuses mainly on research and construction of the motionless transportation necessary for this movement, such as roads, railway tracks, bridges, traffic signs and traffic lights. Traffic engineering is also defined as phase of engineering which deals with planning & geometric design of streets, highways, abutting lands & with traffic operation thereon, as there use is related to the safe, convenient & economic transportation of persons & goods. Traffic engineering is a science of measuring traffic & travel, study of the basic laws relating to traffic flow, generation & application of this knowledge to the professional practice of planning. Traffic signal is a usually used traffic operation manage system at urban roadway intersections. The capacity of urban road network mainly depends on the capacity of the traffic signals. Traffic Signals, also known as traffic lights, traffic lamps, signal lights, stop lights, and traffic control signals, are signaling devices located at road intersections, pedestrian crossings, and other locations to control conflicting flows of traffic. Traffic signals are an important element of traffic control devices. The installation of traffic signals has a central role in calculating traffic hazards at the intersection. An intersection is the crucial point of conflicts and congestion in the road network. Transportation is one of the critical components of the line of work from its early days. As we see, the building of roads, bridges, pipelines, tunnels, canals, railroads, ports, and harbors has shaped the profession. Civil engineering is involved in developing, building, and operating transit facilities, including street railways and underground systems and so on. Kothavalasa Junction (T-Intersection) is one of the mostly important Major District Road (MDR) which connects to the areas of Vizianagaram, Visakhapatnam and Araku. We observed particularly this study area facing the problems like road jams and the problems like congestions, roadside vehicles and infrastructures as the number of road users are increasing quickly. They are needed to be sort out and this is impossible by traffic lights which works on predefined programs as an alternative real time data .In adding to this, it also provides access to many educational institutes, shopping centers, restaurants, corporate offices, grain market etc. Due to the above constraints, its reflection for research work has done so far. Finally at the study area are required to provide a Traffic Signal to enable the efficient traffic control of traffic and also the faster clearing off the traffic from the RESEARCH ARTICLE OPEN ACCESS
