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 ...

Sustainability, 2023 In recent years, numerous turbo-roundabouts have been built in many European countries. To date, there are no turbo-roundabouts in Italy and even the regulations do not provide for their implementation.

Modern suburban roundabouts in Croatia - flower and turbo roundabouts
Scientific Journal of Civil Engineering, 2020Turboroundabouts are specially designed multilane roundabouts with spiral circulatory roadway and physically separated traffic lanes. This roundabout layout was developed in the late nineties of the last century with the aim of increasing the traffic safety and capacity at classic multi-lane roundabouts.

Turbo Roundabouts: Design, Capacity, and Comparison With Alternative Types of Roundabouts
2021Introduction. In turbo roundabouts traffic entry, exit, and circulatory lanes are physically delimited by kerbs (see Fig. 1A). This implies a lowerNnumber of potentially conflicting points (Fig. 1B) between vehicle trajectories than conventional roundabouts (Fortuijn, 2009). By way of an example, in a turbo roundabout with four arms and two circulatory

Calculation of Turbo-Roundabouts with Slip Lanes
Applied Mechanics and Materials, 2014 A turbo roundabout is a particular type of roundabout where all lanes are bounded by traffic signs and by non-mountable curbs installed at entering and circulating lanes.

Can turbo-roundabouts and restricted crossing U-Turn be effective solutions for urban three-leg intersections? [PDF]
Sustainable Cities and Society, 2023 This research explored the potential of replacing conventional single-lane roundabouts by turbo-roundabouts and yield- and stop-controlled restricted crossing U-Turn (RCUT) at intersections located in urban corridors.

Passenger Car Equivalent for Heavy Vehicles Crossing Turbo-roundabouts [PDF]
Transportation Research Procedia, 2016 Turbo-roundabouts represent an innovative scheme of modern roundabouts which provides a spiraling traffic flow and requires drivers to choose their direction before entering the intersection, since raised lane separators mark the lanes on the ring.

Capacity Increase through connectivity for the i-Roundabout and i-Turbo roundabout
2020 Forum on Integrated and Sustainable Transportation Systems (FISTS), 2020Is a roundabout still a good solution in the era where ‘intelligent’ intersection control using vehicle connection (i-TLC), is in upswing? To answer this question, the capacity of ‘i-roundabouts’, where the infrastructure communicates with the vehicles (I2V), is determined analytically.
