Abstract
The Turbo Roundabout is a roundabout fitted with spiral roads to efficiently counteract the complexities of the modern multilane roundabout. This roundabout has an edge over cutting-edge roundabouts regarding capacity and safety and was first invented by Professor Fortujin in 1996. Fast driving speeds and many possible conflicts at multilane roundabout approaches, exits and circulatory roadways are the reasons for this type of construction project. Road designers have been attempting to address these issues over the past few years by implementing new roundabout configurations. Turbo-roundabouts have also spread outside of the Netherlands over the last decade, mainly in Eastern Europe and Germany, but also in North America. While the Dutch model for turbo-roundabout design was strictly applied by some nations, others designed them on experimental sites, resulting in geometrical variations unique to the area. We have more than 390 turbo-roundabouts worldwide today.
In this paper, the measurement of sight distance on turbo roundabouts with an emphasis on “Intersection Sight Distance” to conflicting vehicle circulation will be studied. The traditional graphical approach has been supplemented with the analytical solution consisting of derivation of generalized mathematical equations for intersection sight distance for conflicting circulating vehicle at turbo roundabout.
To determine the design of turbo roundabout instead of standard type we collected numbers, iterations, flow rate and other information from the intersection in Neapol street - M.Hadi-Ashig Alaskar and Vungtau streets in the capital of Azerbaijan, Baku city. The current name of circle is “Ukraine circle” on behalf of friendship between Azerbaijan and Ukraine. Some of these collected specimens were used to perform the by using the software test at the University of Bologna and in Baku Transportation Agency by PTV VISSIM simulation and AutoCAD Civil.
