• 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.
