The article presents issues related to vehicle travel speeds through roundabout intersections. Roundabouts, as infrastructure elements, effectively limit driving speed through their design and provide drivers with better visibility.Compared to other types of intersections, roundabouts are characterized by higher capacity and traffic flow smoothness during transit. Additionally, there are fewer potential collision points at roundabouts than at other types of intersections, thus ensuring a high level of road safety. All these elements make roundabouts, as elements of urban infrastructure, contribute to the realization of tasks formulated by urban transport logistics.
INTRODUCTION
Various types of intersections exist on the road and street network, the purpose of which is to allow the crossing, merging, or diverging of road routes. One of the types of intersections that ensures smooth traffic flow while maintaining an appropriate level of safety for its users is the roundabout
[1, 3, 4, 5, 6, 8, 10, 12, 14]. According to [16], a roundabout is an intersection with a central island and a one-way roadway around the island, where vehicles are required to travel around the central island in a counter-clockwise direction in countries with right-hand traffic or in a clockwise direction in countries with left-hand traffic.
Exceptions to this rule apply to mini-roundabouts, where long vehicles may drive over a traversable island. (…)
