“…These assessments are essential not only for ensuring the sustainability of transportation solutions but also for making informed decisions about infrastructure development, resource allocation, and environmental impact mitigation strategies [2]. From this perspective, conducting comprehensive cost analyses is crucial to support decision making [82]. One major concern is the cost of deploying and maintaining smart systems, although the long-term benefits may outweigh initial costs [2].…”

“…Calibration methods, as discussed by various studies, should ensure accurate predictions [75,76]. A concise overview of select peer-reviewed studies from 2019 to 2023, primarily using PTV Vissim [77] and Aimsun [78], is provided in Table 4 [76,[79][80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98].

“…Microsimulation also remains crucial in transitioning scenarios incorporating cooperative vehicles and communication technology systems (e.g., [76,80,84]). Despite calibration needs, driving simulation technology offers clear advantages over real-scale measurements in evaluating safety, operational performance, and driving behavior [57,75,82]. Building infrastructural and traffic scenarios streamlines roundabout design optimization and enables a thorough assessment of various design solutions and their impact on traffic flow, safety, and overall efficiency (e.g., [14,84,93]).…”

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.

Managed Lane as Strategy for Traffic Flow and Safety: A Case Study of Catania Ring Road

et al. 2022

According to international traffic statistics, the quantity of daily traveling vehicles amounts to one billion, and it is estimated that in 2050 that amount will reach four billion. Urban population is growing especially in large metropolitan areas. This increase has different outgrowths concerning regular circulation, safety, and climatic perspectives. Therefore, the present and further increase of traffic flow is affecting the operational and safety performance of several roadway categories. Urban ring roads belong to a roadway category that is particularly subjected to congestion phenomena, but in many cases, public administrations are unable to afford required expenses to upgrade or build new roadways. Therefore, an intervention is needed that increases the capacity of existing infrastructures with limited cost results to be fundamental. In such a framework, the dynamic use of hard shoulder running (HSR) would represent a valid solution that both exploits existing infrastructures and facilitates traffic outflow by implementation of smart digital roads, with limited interventions on the physical infrastructure. Despite the expected improvements in traffic capacity, the HSR poses safety issues particularly in specific locations (e.g., interchanges) and for the operation of the transition phase for opening and closing the HSR. In this paper, the applicability and usefulness of microsimulation were tested with the Catania (Italy) ring road, as a case study, through the application of VISSIM traffic microsimulation software and SSAM traffic conflict tool, implementing different scenarios for the activation of the HSR.
