| Περίληψη: | The design of the geometry of a roundabout involves choosing between trade-offs of safety and capacity. A well-designed roundabout operates most safely when its geometry forces vehicles to enter and circulate at slow speeds, achieving a smooth speed profile by requiring vehicles to negotiate the roundabout along a curved path. According to FHWA publication Roundabouts: An Informational Guide, the fastest path modeling is a critical component of safe roundabout design. As the construction of roundabouts is quite new in Greece, the driver behavior entering a roundabout is required to be investigated. This paper presents the results of experimental research that has been conducted as a first step in the development of a vehicle speed model for roundabouts in Greece. The research aims to define the basic path elements of vehicle movement in the roundabout at which the maximum speed is achieved. To address this need, a detailed analysis of actual field-measured speeds was carried out on a sample of 6 straight directions through multilane roundabouts in Greece, characterized by different geometric elements. Roundabouts’ performance was recorded with the use of an Unmanned Aerial Vehicle during free flow conditions on weekdays. Trajectories and kinematic characteristics of the vehicles were extracted. Measured speeds along the curved paths were compared to the predicted speeds that USA guidelines define. The findings from the study show a significant difference between actual and predicted speeds and a strong correlation between speed and design elements. |
