Abstract :
Abstract-This paper compares the capacity analysis suggested by the Federal Highway Administration (FHWA) roundabout guidelines with those of the Transportation Research Board (TRB draft report, 2006) and National Highway Cooperative Research Program (NHCRP report 572). The result will be given in term of average control delay time, 95th percentile queue length, and capacity of the critical lane in the critical approach, or the overall approach depending on the method used.
