| 摘要： | 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. |
