of modern roundabout at Rajendra Park Chowk which is situated in Durg, Chhattisgarh which provides connectivity between Durg junction, Indira market and Bus stand. The regulation of traffic will become very difficult in peak hours at this chowk the traffic increases by 40% to 50% than normal regular traffic. The main focus of this study is aimed at understanding the traffic pattern and congestion, its measurement and how to overcome from this problem. Rajendra Park square is one of the busiest rotary intersections in Durg, serving as a junction through which numerous vehicles enter and leave the city. This further aggravates the traffic problem of the rotary intersection. The study is based on the traffic signal position, timing, traffic volume, pattern and behavior of people. The aim of this project is to assess and study the rotary intersection at Rajendra Park square. This will include site investigation, measuring the present geometry of the intersection, followed by traffic volume count. Based on the above data, we will suggest a new design for the modern roundabout that can handle the present and anticipated traffic scenario at Rajendra Park square in Durg.
This is a case study of a Rajendra park chowk in Durg, Chhattisgarh. Which was n't handed with rotary junction in past. So, we study the traffic pattern and volume to make a rotary intersection.
Key Words: Modern roundabout, Peak hour, Traffic volume count, Traffic congestion.
1.INTRODUCTION In our nation, particularly in urban areas, traffic conditions are extremely mixed. Excessive flow of vehicles is one of the main reasons behind traffic congestion at megacity road and intersection sites. With increased numbers of vehicles, the capability and efficiency of junctions drop. To cure these problems and improve the level of service quality for road customers, efficient traffic regulation is urgently needed. Traffic congestion, especially caused by bottlenecks at intersections, is a major problem in urban areas. Intersections are important components of the road network of a city from the viewpoints of capacity, traffic flow, and safety and are usually the target of public frustration with traffic control in big cities.

Roundabouts are generally between 45 and 200 feet in diameter and are intended for use by vehicles traveling at speeds of 15 to 25 miles per hour. Modern roundabouts are different from traffic junction or intersection and traffic circle. Classic traffic circles and intersections, which were typically over 0.057 mile in diameter, fell out of favor in the 1950. This was primarily because driving speeds increased (over 30 mph) and the complicated, frequently confusing weaving maneuvers they necessitated—particularly because entering cars were usually given priority, so the system became inefficient and dangerous.
Traffic congestion on main urban roads, caused mainly by recurrent bottlenecks at intersections, presents a challenging issue—mainly in big metropolitan areas. Intersections are the most crucial components of an urban
