CASE STUDY ON IMPLEMENTING TRAFFIC CALMING DEVICES: AN EXAMPLE FROM THE STREET AND ROAD NETWORK IN KHARKIV

The continuous growth of the car fleet and the underdevelopment of city streets and road networks require constant improvement in traffic management. The article suggests considering modern means, such as traffic calming, an essential component of strategies for ensuring road safety and creating a comfortable public area.
The analysis of existing traffic calming devices and their application practice abroad have proved the need for their widespread implementation to reduce vehicle average speeds to a safer level, reduce the number of road accidents and the severity of their consequences, and improve the conditions for movement on the street and road network for all road users.
The article analyses the implementation of three schemes of traffic management at a pedestrian crossing, namely, with the use of road signs and road markings only; with the provision of an elevated pedestrian crossing, road signs and road markings; with the use of road humps, road signs and road markings. The dependences of the average length of the traffic jam, the average delay time, and the average number of stops of one vehicle on the intensity of traffic and pedestrian flows when arranging a pedestrian crossing under the three options are obtained, which can be used for a preliminary assessment of their arrangement at pedestrian crossings.
It is substantiated that the average value of the traffic jam length, the average number of stops, and the average delay per vehicle are influenced by the traffic flow intensity, where the estimated indicators increase with their increase. As the area of influence of traffic calming devices and their geometric characteristics increases, the evaluation indicators also increase, i.e., since an elevated pedestrian crossing has smaller geometric parameters than a complex of pedestrian crossings with road humps, we have lower values of the evaluation indicators.
