Assaying Traffic Settings with Connected and Automated Mobility Channeled into Road Intersection Design

open access: yesSmart Cities
This paper presents a microsimulation-driven framework to analyze the performance of connected and automated vehicles (CAVs) alongside vehicles with human drivers (VHDs), channeled towards assessing project alternatives in road intersection design.

Conversion of existing roundabouts into turbo-roundabouts: case studies from real world, Journal of Civil Engineering and Architecture 6(8)

open access: yes, 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 through the intersection; they both can improve road safety conditions at the junction ...

A Synthesis of Practice in the Use of Turbo Roundabouts

open access: yes
The turbo roundabout by reducing speeds and enhancing separation between users, turbo roundabouts support the Safe System Approach to reduce the severity and incidence of crashes. This presentation summarizes the safety and operational performance and key considerations for successful implementation in the US.

Road traffic safety at Polish turbo roundabouts with raised lane dividers [PDF]

open access: yes, 2013
Ronda turbinowe to nowy, w polskich warunkach, typ skrzyżowania. Są to skrzyżowania wielopasowe (w Polsce najczęściej dwupasowe), które nie posiadają wad typowych dla rond wielopasowych, takich jak niski poziom bezpieczeństwa ruchu drogowego oraz ...

Ellipse offset curves in the formation of turbo-roundabouts

open access: yesRoads and Bridges - Drogi i Mosty, 2015
Various curves are used for shaping the geometry of roads and a curve applied the most often is the circular arc. Clothoid, spiral, ellipse, sets of curves shaped with polynomial functions and other similar curves are also worth mentioning. The road axis is usually set during practical realization of the curves in the terrain.

Turbo-Roundabouts: a Model to Evaluate Capacity, Delays, Queues and Level of Service

open access: yes, 2012
A turbo roundabout is a particular type of roundabout where entering and circulating lanes are bounded by traffic signs and by non-mountable curbs. The physical separation between lanes, both at entries and on the ring, helps to prevent side collisions

Signalized Turbo Roundabouts: A Study into the Applicability of Traffic Signals on Turbo Roundabouts

open access: yes, 2013
Since the 1980s, the modern single-lane roundabout has been applied in the Dutch road network. The roundabout offered major safety benefits compared to the conventional signalized intersection, however, it also required more space.
