INFLUENCE OF PASSENGER ROUTE TRANSPORT ON TRAFFIC SAFETY ON THE STREET AND ROAD NETWORK

Abstract

Abstract.The public transport comprises homogeneous vehicle movement. The motion of public transport passing through a road section exhibits signs of stationarity, hence formulating the stated scientific task. The paper proposes to assess the safety level of passenger public transport movement by deviations of the movement characteristics of public transport vehicles from the characteristics of the flow vehicles. The analysis conducted by the authors and the corresponding synthesis of the general conditions of passenger public transport movement in traffic flow on public roads allowed formulating a system of interaction between three elements: traffic flow, passenger transport vehicles, and road conditions. The provided criteria for deviation of the movement characteristics of passenger public transport vehicles from the characteristics of the traffic flow subsequently enable the evaluation of the danger level on the route. The proposed overall characteristic indirectly allows evaluating the safety level of passenger public transport movement on roads according to the provisions of traffic flow theory. To formulate general characteristics regarding the consideration of road safety at sections and nodes of the street-road network through which the route passes in the methodology of calculating urban bus transportation routes.
