A Novel Methodology for Estimating the Capacity and Level of Service for the New Mega Elliptical Roundabout Intersection

摘要: Mega elliptical roundabout is a new intersection on rural multilane highways. This was developed in previous paper using simulation data, and the authors found that it better than interchange (full cloverleaf) most scenarios of traffic flow. Basically, there are no guidelines or procedures for designing mega AASHTO Green Book, Federal Highway Administration guides, Capacity Manual. Thus, purpose this study to analyze operation performance propose methodology calculating capacity also level service by gap acceptance theory. Moreover, research studied influence different values truck ratios major highway speed geometric design roundabout. To validate thoroughness proposed methodology, VISSIM simulations were conducted. will assist practitioners determining appropriate design, assessing intersections, making comparisons with other alternatives.
