Develop Traffic Capacity Models for Mini-Roundabouts from Simulation
Project Information
Project ID:
FHWA-PROJ-11-0045
Project Abstract:
No capacity models for mini-roundabouts exist, other than from ARCADI, a UK model whose equations are unpublished. Based on VisSim and using typical sizes of small size roundabouts, layouts and models will be developed to simulate at least two typical designs. The models will include effects of large vehicles and assumptions about driving behaviors. The objective is to simulate numerous traffic scenarios representative of all possible traffic volume conditions and estimate maximum throughput at one of the approaches. The maximum throughput data will be fitted in an exponential function as a function of circulating or conflicting volume, and percent of large vehicles.
Goals
Develop capacity equations for a 50-foot and 75-foot inscribed circle diameter (ICD) mini-roundabout from driver performance in the United States.
