Abstract:

The vehicle ownership is increasing day-by-day with the population growth. The traffic scenario is also changing along with this change. Roundabout has been widely adopted alternative as a type of intersection in many parts of the world due to its convenience for operation with lesser conflict points than the other unsignalized intersections. The capacity of roundabout intersection is the important or we can say key parameter to check the performance of roundabout intersection. The capacity of the roadway roundabout depends on the flow at different legs approaching the roundabout. The performance of roundabouts in terms of queues, delays and saturation index typically depends on entry capacity. This paper discusses and reviews the capacity estimation of roundabout which have done in past by various methods by different research scholars from various parts of the world. This study can contribute to an improved understanding of one of the parameter of performance of roundabout i.e. capacity of roundabout.
