Predicting Operating Speeds at Urban Multilane Roundabouts in Abu Dhabi, United Arab Emirates
Journal of Advanced Transportation, 2018 There are more than 460 multilane roundabouts located in Abu Dhabi, the capital city of the United Arab Emirates, and its surrounding areas. Most of those roundabouts have three entry/circulatory/exit lanes with large radii, which resulted in the ...

Moving from Conventional Roundabouts to Turbo-roundabouts
Procedia - Social and Behavioral Sciences, 2014 AbstractThis paper introduces the turbo-roundabout concept and compares its performance with the conventional double-lane roundabout in terms of safety and capacity. While researchers agree as to the safety benefits of turbo-roundabouts, improvement in terms of capacity is still open to discussion. The application of a new calculation method shows that

Analyses of maximum-speed path definition at single-lane roundabouts
Journal of Traffic and Transportation Engineering (English ed. Online), 2018 The process of designing roundabouts is an iterative process through which, in several checks, the design elements of a roundabout get optimized. Existing regulations for roundabouts involve swept path analyses, sight distance analyses and speed analyses

Turbo-roundabouts vs Roundabouts Performance Level
Procedia - Social and Behavioral Sciences, 2012 AbstractIn this paper the performance level of basic turbo-roundabouts and double-lane roundabouts are compared. Cowan's M3 headway distribution was chosen to take into account bunched vehicles moving along each circulating lane; the Hagring model was adopted to evaluate entry capacity both at turbo-roundabout and at double-lane roundabout.The ...
