Roundabouts are providing safer intersection experiences for motorist than can be achieved at stop-controlled intersections by reducing the potential contact points between vehicles. When designing roundabouts, entry lane capacity can be determined by collecting local data to calculate operational parameters of critical gap and follow-up headway. Software packages such as VISSIM and SIDRA can aid in the design process. This thesis will provide guidelines to accurately evaluate capacity of a local roundabout by comparing the Maximum Likelihood Method with a method provided in the Highway Capacity Manual and by default data from simulation software. This information is applied to determine the viabilities of building roundabouts near school zones. School zones present a unique design challenge because the roundabout provides for lesser delays for vehicles traversing the intersection than would be encountered with a stop-controlled intersection. Roundabouts can deliver more vehicles to the queue, therefore increasing travel times. This thesis explores design adjustments and applies them along with utilization of school properties to optimize travel times.
