Abstract

Roundabouts play a crucial role, especially in the moderately populated areas and places which are largely residential and are in the vicinity of schools where traffic lights are not in place. Though roundabouts can significantly solve the congestion problem on intersection roads, the mobility and time delay depend on the capacity of vehicles. In high traffic moments, the congestion will affect the smooth traffic flow and the queue length on the secondary lane. According to systematic regulations, the cars from the secondary lane need to wait for the cars on the main lane to move forward so as to create a sufficient space to enter the roundabout. In addition, the incoming cars from the main lane have the priority to pass through the arm junction, and the cars on the secondary lane have to make sure these incoming cars are totally driven through the arm junction, before they can be allowed to enter the roundabout. Based on the phenomena mentioned, a long waiting time takes place on the secondary lane. Therefore, a waiting system needs to be installed to facilitate traffic flow on the secondary lane as well as to determine the number of cars crossing the arm junction from the incoming main lane to the outgoing main lane. The plots of Total Travel Time, Total Waiting Time and queue length with different parameters are simulated and discussed. Finally, the results presented in certain simulated situations, produced the tailback on the secondary lane and occasionally, eased the traffic flow due to the mentioned priority regulations.
