“…Regarding the second study trajectory, enhancing roundabout safety through smart technologies involves integrating advanced systems for vehicle-to-vehicle communications, real-time monitoring, and control. These technologies aim to mitigate risks by detecting potential hazards, optimizing traffic flow, and providing timely alerts to drivers, thus improving overall safety at roundabouts [110][111][112][113][114][115]. Lee [110] raised doubts about the reliability of smart systems and stressed the importance of conducting practical assessments to gauge their effectiveness.…”

“…However, safety constraints pose challenges for autonomous vehicles in assessing cornering at roundabouts. Another study [113] analyzed vehicle behavior across curved trajectories, particularly focusing on a passenger car navigating a constant roundabout turn. Stability was observed within speeds of 10 to 74 km/h, with a critical zone beyond.…”

“…Specifically, the synthesis review allowed us to aggregate and analyze findings from multiple studies, serving as a starting point to reconsider the potential of roundabouts as effective solutions in the context of smart mobility. Despite the potential benefits outlined in the research trajectories, implementing smart technologies in modern roundabouts faces various barriers and challenges [113,114]. One concern is the cost of deploying and maintaining these systems, although the long-term benefits may outweigh initial costs [2].…”

This paper explores the domain of intelligent transportation systems, specifically focusing on roundabouts as potential solutions in the context of smart mobility. Roundabouts offer a safer and more efficient driving environment compared to other intersections, thanks to their curvilinear trajectories promoting speed control and lower vehicular speeds for traffic calming. The synthesis review supported the authors in presenting current knowledge and emerging needs in roundabout design and evaluation. A focused examination of the models and methods used to assess safety and operational performance of roundabout systems was necessary. This is particularly relevant in light of new challenges posed by the automotive market and the influence of vehicle-to-vehicle communication on the conceptualization and design of this road infrastructure. Two case studies of roundabouts were analyzed in Aimsun to simulate the increasing market penetration rates of connected and autonomous vehicles (CAVs) and their traffic impacts. Through microscopic traffic simulation, the research evaluated safety and performance efficiency advancements in roundabouts. The paper concludes by outlining areas for further research and evolving perspectives on the role of roundabouts in the transition toward connected and autonomous vehicles and infrastructures.
