Simulation-based performance evaluation for smart road systems

With the growing integration of smart technologies in transportation, the study of roundabout operational efficiency and safety remains a pertinent research area. This paper presents a novel method for evaluating roundabout performance using simulation-based techniques. By analysing two roundabout case studies in Aimsun, the study explores the implications of increasing market penetration of cooperative, connected, and autonomous vehicles on traffic dynamics. The study involves processing geometric and traffic data, categorizing entry lane types, developing benchmark capacity functions, processing micro simulator input data, and conducting sensitivity analysis for model calibration. The findings advance roundabout design and management in smart road systems and offer insights into the intersection of roundabout research and smart mobility solutions.
