Microsimulation-based passenger car equivalents for heavy vehicles driving turbo-roundabouts
Transport, 2016 Due to its geometric design, turbo-roundabouts impose greatest constraints to the vehicular trajectories; by consequence, one can expect a more unfavourable impact of heavy vehicles on the traffic conditions than on other types of roundabouts.

Performance Evaluation of a Hybrid Roundabout Using a Microscopic Simulation
The Baltic Journal of Road and Bridge Engineering, 2021 Roundabouts are one of the safest types of intersections. There are a number of roundabout types in literature. Each roundabout type is distinguished by some characteristics.

Conversion of Existing Roundabouts into Turbo-Roundabouts: Case Studies from Real World [PDF]
Journal of Civil Engineering and Architecture, 2012 Compared with roundabouts the main advantages of turbo-roundabouts are the reduction in the number of potential conflicting points and the lower speed of vehicles passing through the intersection, they both can improve safety conditions at the junction. Moreover, the physical delimitation among lanes limits the side-by-side accident risk. These aspects

Conversion of a Semi-two Lanes Roundabout into a Turbo-roundabout: A Performance Comparison
Procedia Computer Science, 2016 AbstractIn the last years, as regards the functional design of at-grade intersections, near to classic layouts (signal-controlled junctions, roundabouts, etc.) a new solution has born: the “turbo-roundabout”. It is a canalized multilane oval intersection with a non-traversable or partially traversable center island and with a spiral circulatory ...

Safety and Efficiency Analysis of Turbo Roundabout with Simulations Based on the Lujiazui Roundabout in Shanghai [PDF]
Sustainability, 2020 Traditional multilane roundabouts have many branch lanes without traffic signs and channelization, which leads to a high tendency for traffic collisions. Turbo roundabouts are a new design that has the potential to reduce lane-change conflicts using canalization to force drivers to keep in specific lanes based on their intended destination.

Determinants of crash numbers and constellations at turbo roundabouts in Germany
Traffic Safety ResearchTurbo roundabouts are a relatively new design. Thus far, research on their safety has focused on comparisons with other types of intersection and the effects of physical lane dividers.
