Modeling and Calibrating Capacity of Large Roundabouts
Roundabout models, available in the literature widely, vary between one method and another. Majority of the models are solely based on circulating fl ow to estimate capacity. The relationship between maximum entry fl ow of large dual and triple lane roundabouts and their geometric and traffi c characteristics is investigated here for saturated fl ow condition using multivariate analysis. The de...

Roundabout is one of the most effective intersection control methods in the world. Although, they have often been used in Iran, but, the methods which are proposed to analyze roundabouts are very old and new regulations are not implemented for analyzing modern roundabouts. There are strong needs to apply new modern analyzing methods for studying roundabouts in Iran. Also, these methods should b...
متن کاملCapacity and Delay Estimation for Roundabouts Using Conflict Theory
To estimate the capacity of roundabouts more accurately, the priority rank of each stream is determined through the classification technique given in the Highway Capacity Manual 2010 (HCM2010), which is based on macroscopical analysis of the relationship between entry flow and circulating flow. Then a conflict matrix is established using the additive conflict flow method and by considering the ...
متن کاملCapacity Estimation Model for Signalized Intersections under the Impact of Access Point
Highway Capacity Manual 2010 provides various factors to adjust the base saturation flow rate for the capacity analysis of signalized intersections. No factors, however, is considered for the potential change of signalized intersections capacity caused by the access point closeing to the signalized intersection. This paper presented a theoretical model to estimate the lane group capacity at sig...
متن کاملCapacity-Related Driver Behavior on Modern Roundabouts Built on High-Speed Roads
Ahmad, Shaikh.M.S.C.E.,Purdue University, December 2014.Capacity-Related Driver Behavior on Modern Roundabouts Built on High-Speed Roads. Major Professor: Andrew Tarko. The objective of this thesis was to investigate the factors that affect capacity-related driver behavior on modern roundabouts built on high-speed roads. The capacity of roundabouts is strongly affected by the behavior of driver...
