SIMULATION of DIFFERENT INTERSECTION DESIGN for IMPROVING TRAFFIC FLOW with FACTORS CONSIDERING LOCATION, POPULATION and DRIVER EXPECTANCY Sourabh Kumar Singh Dr
Science, Technology and Development ISSN : 0950-0707 SIMULATION OF DIFFERENT INTERSECTION DESIGN FOR IMPROVING TRAFFIC FLOW WITH FACTORS CONSIDERING LOCATION, POPULATION AND DRIVER EXPECTANCY Sourabh Kumar Singh Dr. Anil kunte Associate Professor, Research Scholar, Associate Professor, Department of Civil Department of Civil Department of Civil Engineering Engineering, Shri JJT Engineering, Shri JJT Noida International University University University Dr. Paritosh Srivastava Abstract: In today’s economic growth the vehicular traffic is increasing day by day, which leads to failure of intersections before their time period. To increase the efficiency of these failed intersections the engineers added lanes to the existing major and minor roads, but this method do not give results which it used to deliver in the past, hence other methods were adopted. So to increase the efficiency and fulfil the criteria for successful intersection ,to cape with it several intersection are designed which are unconventional in nature like jug handle, bow tie, continuous flow intersection and median u turn which are very effective in increasing green time on highway and minor roads. The software used in this study is Auto- cad for planning and drawing purpose which can be used in sim-traffic software which will be used for simulation purpose of the traffic flow on different designs of intersections. The factors which are considered in this study are -location of town centre, population of the zone and driver expectancy. The final conclusion of this study is that continuous flow intersection provides the best results when the traffic is increased. The construction cost is least in median u turn and giving maximum result than all other intersections. -

Intersection and Interchange Geometrics PROJECT CASE STUDY
Intersection and Interchange Geometrics PROJECT CASE STUDY For North Carolina, Implementation of Superstreets Means Travel Time Improvement, Reduction in Collisions, and Fewer Injuries and Fatalities Increasing traffic delays at intersections are a common problem faced by Departments of Transportation (DOTs) across the nation. North Carolina is making strides in tackling delays in suburban, high-volume arterial areas through the implementation of “superstreets,” also known as restricted crossing U-turns (RCUTs). These arterial surface roads can move high-traffic volumes with less delay by re-routing left-hand turns and crossing maneuvers coming from the side streets. Instead, at an RCUT, drivers make a right turn onto the major highway and then make a U-turn through a median. While this may seem time-consuming, studies show it can result in significant time savings. At signalized intersections, the overall time savings efficiencies are due to the ability of the major highway to have a greater percentage of green time to allow the heavy through volumes of traffic to proceed. At unsignalized intersections, traffic from the minor street may actually save time since drivers are not stuck waiting for the long traffic gaps needed to go across the bust thoroughfare or make the left-hand turn. North Carolina has deployed the superstreet concept at intersections across the state, including a corridor of signalized intersections along U.S. Route 17 near Wilmington.
