Abstract:The Connecticut Department of Transportation (ConnDOT) has constructed four roundabouts in
the State of Connecticut within the past ten years. VISSIM, a microscopic traffic simulation software
program was utilized to analyze roundabout during their design phase. This project has collected a
variety of traffic data at the roundabouts using Miovision Technologies. A large sample size of field
data was analyzed to achieve accurate and statistically significant results. The research
investigated a series of simulation parameters as calibration factors for describing driver behaviors
at roundabouts. A VISSIM simulation of existing roundabouts was built to compare both queue
length and travel time as predicted from simulation with measured field data. In the end, this project
identified VISSIM input variables most critical to accurate modeling; summarized the recommended
parameter values; and, provided recommendations for roundabout traffic operations modeling.
