An intersection which is not well designed, particularly traffic flow on state highways with high speed, when mixed up with local traffic at crossings, traffic congestion is likely to occur. This causes many negative effects like pollution, delay and improper traffic management at crossings. Intersections represent potentially dangerous locations from point of view of traffic safety. It’s believed that well over half the fatal and serious road accidents in built-up areas occur at junctions, Therefore, it is essential to design or re-design the intersections in a further reasonable way. The basic methods considered for the design includes the principles of Uniformity and Simplicity, Minimizing conflict points and smoothing the traffic flow are possible by means of space and time sharing. The purpose of this paper is to review a number of methods that encompass of design of intersection. And it helps intersection design and evaluation of different design options’ suitability and checks the intersection’s performance. Keywords: - Intersection, Conflict Points, Time Share and Space Share. 1. INTRODUCTION An intersection is where two or more roads join or cross at-grade. The intersection comprises the areas required for all means of travel: pedestrian, bicyclist, motor vehicle, and transit. Thus, the intersection includes not only the pavement area, but typically the adjacent sidewalks and pedestrian ramps. At the intersection there are through, turning and crossing traffic and these traffic movements may be handled in different ways depending on the type of intersection its design and control of traffic. Generally, intersection problems are unavoidable except in case of expressways or freeway systems where such problems are avoided by providing grade separated intersection and controlled access. Signal control is a frequently used remedy of capacity shortage in urban areas. A sufficiently accurate method of predicting the capacity of signalized intersections is important for correct road way design and for effective traffic management. Signal control is generally considered to be the highest type of control possible at an at-grade intersection. If the signal control plan is not designed properly, the signal control may become counterproductive. The ill effects of improper signal plan can be congestion, undue delays, fuel wastage, air pollution, reduced intersection capacity and tremendous inconvenience for the road user. To avoid such a situation, it becomes mandatory on the part of the traffic engineer to study the traffic situation thoroughly, to understand it properly and to evolve the optimum cycle time and proper phasing to suit the requirements of the traffic with due consideration to the location geometrics. Intersections are a key feature of road design in four respects: i. Focus of activity: The land near intersections often contains a concentration of travel destinations. ii. Conflicting movements: Pedestrian crossings and motor vehicle and bicycle turning and crossing movements concentrated at intersections. iii. Traffic control, At intersections, movement of users is assigned, through traffic control devices such as yield signs, stop signs, and traffic signals. Traffic control often results in delay to users travelling along the intersecting roadways.
