Investigation of roundations and comparison with engineering methods, round intersection example in Elazığ province

This study comprehensively investigates the engineering characteristics and operational performance of roundabouts in Elazığ province. The main objective of the study is to analyze the design and operational characteristics of these roundabouts in depth and compare the engineering methods that can be applied to improve traffic safety and flow. In this context, a detailed field study was carried out on selected samples of existing roundabouts in Elazığ; traffic flow characteristics and intersection design parameters were examined in detail. The research findings show that in the design of roundabouts, factors such as signalization, lane widths, turning radii and pedestrian crossings play critical roles on traffic flow. Furthermore, the analysis in Elazığ revealed that some intersections are inadequate due to traffic density and vehicle diversity. In this context, the capacity of roundabouts should be increased and safety measures should be strengthened to prevent traffic congestion and accidents. In particular, it is crucial to design and manage roundabouts more effectively by utilizing modern engineering solutions and technological innovations. The study proposes engineering interventions and management strategies to make roundabouts safer and more efficient. These strategies are essential to improve the functionality of roundabouts and optimize traffic flow.
