Multi-objective Scenario Traffic-Based Analysis for Roundabout Environment Enhancement

Roundabouts have been viewed as a powerful movement control technique under a particular activity conditions for quite a long time. Single-path roundabouts, the most well-known compose, have just eight potential conflict points. Automobiles are enforced to decrease speeds because of the geometric of the roundabouts. If the roundabouts were designed in an accurate way, they demonstrated to have positive security and utilitarian exhibitions. The purpose of this research was to study the possibility of improving the design of existing roundabouts, comparing different design scenarios (alternatives) via Synchro and finding out the best scenario by analyzing the results of level of service capacity utilization, delay, travel time, speed, number of stops, and fuel consumption. The study area is located at Al Bidaa area; the network studied included the intersection of Blajat Street and Amr Ibn Al Aas Street. The base-year traffic data were obtained from the traffic impact study conducted by Egis Bceom International in October 2009. As the analysis focuses on the year 2030, growth factors and calibration of the traffic volumes were done in accordance with the guidelines set by Kuwait Municipality. The results obtained showed that for intersection 1, the implementation of a roundabout and a ramp (Scenario 2) has the highest impact, especially when considering the amount of emissions reduced. As the traffic reduced due to the ramp, the roundabout flow became more freely with the majority of traffic arriving from Fifth Ring Road. Implementing this scenario decreased the fuel consumption and related emissions by 55% (the highest among other scenarios (an increase in consumption was observed for scenario 3). As for the level of service and capacity utilization, the reduction was almost similar for all scenarios at 60% for the morning peak hour and 52% for the afternoon peak hour.
