“…Regarding estimated emissions, there was a progressively increasing percentage reduction across different MPRs. The trend of CO 2 emissions in Figure 6d is decreasing for each ELP, as expected, due to the increasing presence of CAVs in traffic [3,10]. It is also noted that, the percentage reduction of pollutant emissions across different MPRs was greater in the case of ELP 2 and ELP 3 than in ELP1; in the three ELPs, the environmental advantage achievable was similar in the case of MPR 4 and a fully CAV fleet.…”

“…Identifying analogies or differences in globally implemented roundabout design standards and practices was necessary to answer key question 1 (see Section 1) and to evaluate the impact of curved geometry on operational performance. Despite aligning design principles and geometric elements with overarching objectives, models and methods used in the safety performance evaluation and operational analysis for roundabouts must now consider the functional requirements of cooperative driving [5,10,11].…”

“…Clear recommendations for single-lane and multi-lane roundabouts should be also established to consider the functional requirements of cooperative driving [5,10]. In urban areas, prioritizing cyclists and ensuring unimpeded pedestrian access is paramount, while outside built-up areas, such privileges may differ.…”

“…This dynamic interplay signifies scenarios where human intuition should complement the precision of autonomous systems, fostering harmonious coexistence [8]. Beyond automation, the connectivity of vehicles plays a crucial role, serving as a foundational element for smart cities [9,10]. With the increasing prevalence of connected and autonomous vehicles (CAVs) in traffic, the transition toward vehicle-to-everything (V2X) communication underscores the imperative nature of intersection management [11].…”

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.

The introduction of connected automated vehicles (CAVs) on freeways raises significant challenges, particularly in interactions with human-driven vehicles, impacting traffic flow and safety. This study employs traffic microsimulation and surrogate safety assessment measures software to delve into CAV–human driver interactions, estimating potential conflicts. While previous research acknowledges that human drivers adjust their behavior when sharing the road with CAVs, the underlying reasons and the extent of associated risks are not fully understood yet. The study focuses on how CAV presence can diminish conflicts, employing surrogate safety measures and real-world mixed traffic data, and assesses the safety and performance of freeway interchange configurations in Italy and the US across diverse urban contexts. This research proposes tools for optimizing urban layouts to minimize conflicts in mixed traffic environments. Results reveal that adding auxiliary lanes enhances safety, particularly for CAVs and rear-end collisions. Along interchange ramps, an exclusive CAV stream performs similarly to human-driven ones in terms of longitudinal conflicts, but mixed traffic flows, consisting of both CAVs and human-driven vehicles, may result in more conflicts. Notably, when CAVs follow human-driven vehicles in near-identical conditions, more conflicts arise, emphasizing the complexity of CAV integration and the need for careful safety measures and roadway design considerations.
