Determining Louisiana’s Roundabout Capacity

The primary objective of this project is to use local data to determine Louisiana’s roundabout capacity and compare to software outcomes which are currently being used in the planning and design of modern roundabout in Louisiana. Specifically, the main objectives are to conduct a literature review on the roundabout capacity models as presented in the Highway Capacity Manual (HCM) 2010 and HCM 6, highlighting differences and similarities and comparing to Sidra capacity estimation methods, select candidate sites for local data collection to be used for parameter estimation, compare parameters obtained from site observations to HCM 2010, HCM 6, and Sidra outputs, and make a recommendation on best practices to be followed in determining parameters that best reflect local driver behavior.
