Improved applicability diagram of two-lane roundabouts [PDF]
International Conference on Road and Rail Infrastructure, 2021 When reconstructing existing or constructing completely new intersections, the main problem is determining the type of future intersection. Capacity is one of the key indicators that influence the choice of traffic control type. In this paper, using different scenarios of theoretical traffic flow distributions and traffic volume scenarios, the authors ...

Improving cycling safety through infrastructure design: A bicycle simulator study
Transportation Research Interdisciplinary Perspectives, 2023 This study investigated the impact of two road treatments on cyclist behaviour using an bicycle simulator. The treatments were sharrows (presence or absence) at a roundabout and widening an on-road bike lane (width 1.2 m or 1.8 m) on a curved mid-block ...

Turbo roundabout - An alternative to classic two lane roundabout
Put i saobraćaj, 2023 Traffic congestion and the questionable safety of two-lane roundabouts are two justified criteria for the introduction of turbo roundabouts. The increase in capacity, which also results in an increase in the level of service, is a positive aspect of this alternative type of roundabout.

IET Intelligent Transport Systems, 2022 This paper develops a distributed cooperative control strategy (DCCS) to plan and optimize the collision‐free trajectory for the connected automated vehicle (CAV) at an isolated roundabout. The representation of the trajectories of CAVs is defined within

Assessment of turn signal use at two-lane roundabouts in Doha city
Procedia Computer Science, 2022 Turn signal and lane change indicators can be identified as an effective way for drivers to communicate with each other. Additionally, the use of turn signals has significant safety implications. This study explored the usage of turn signal indicators when approaching and leaving two-lane roundabouts. In total, 415 and 400 vehicles entering and exiting

Roundabouts - drivers' attitudes about the way of moving in two-lane roundabouts
Put i saobraćaj, 2021 In the last few years, there has been an expansion in the construction of roundaboust. The construction of roundabouts, raised the level of traffic safety. However, it can not be said that all roundabouts have the same level of traffic safety. One-lane roundabouts belong to the category of roundabouts with the fewest points of conflict, and then ...

A Curvilinear Decision Method for Two-lane Roundabout Crossing and its Validation under Realistic Traffic Flow [PDF]
2020 IEEE Intelligent Vehicles Symposium (IV), 2020 Autonomous vehicles navigation in complex scenarios is still an open issue. One of the major challenges is the safe navigation of autonomous vehicles on roads open to public traffic. Indeed, behaviors and intentions of human-driven vehicles are hard to predict and understand.

MPC Tracking Controller Parameters Impacts in Roundabouts
Mathematics, 2021 The work is proposed to design a controller of the form known as the roundabout scenario trajectory tracking problem. The road condition is a four-leg, single-lane roundabout; the reference path is given.

New Type of Roundabout: Roundabout with “Depressed” Lanes for Right Turning – “Flower Roundabout”
Promet (Zagreb), 2011 Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries; however, the solution, whereby the number of conflict points is ...
