Traffic Delay Evaluation and Simulating Sustainable Solutions for Adjacent Signalized Roundabouts
Roundabouts are proven to be an excellent solution to enhance traffic safety in comparison with intersections. However, multilane roundabouts with more than four approaches do not yet have any clear recommendations for the traffic signal installation neither the type of solution that can be applied to improve the Level of Service (LOS). This paper aims to evaluate signalized roundabouts that have multilane with more than four approaches to help to find sustainable traffic congestion solutions. The PTV-VISSIM software was used to evaluate the current operational performance and simulate multiple solutions for improvement. Traffic and geometric data of two adjacent signalized roundabouts (Al-Kuwait roundabout and Government square) in Sharjah City were used for this study. The two roundabouts are connected through a one-kilometer road.
The results showed that the current LOS of both roundabouts is “F,” and there is no significant effect on the operational performance from each roundabout on the other. Moreover, the suggested solution showed LOS “D” with a 58% reduction in vehicle delay and a 60% reduction in stop delay for Al-Kuwait roundabout. While the reduction on the Government square was 62% and 65% for the vehicle delay and in stop delay respectively with a Level of Service “D” Overall, there is an indication that the suggested solution can reduce traffic delay significantly at this type of roundabouts; however, further research is highly recommended to estimate the economic, environmental, and safety benefits of the suggested solution.
