Abstract
The theory of the transport infrastructure objects design is generalized and further developed in the example of the railway junction. A mathematical model for determining optimal design parameters for road junctions in railway junctions from the position of resource saving and ensuring traffic safety is presented. The current methods for calculating overpasses are aimed at constructing geometric shapes without carrying out optimization calculations to determine the design parameters. The model is based on the minimization of capital costs in the construction of a roadside intersection at optimal intersection angles, radiuses of curve sections and marks of crosses of turnouts. A general model of risk management for the occurrence of transport accidents on the approaches to the node is presented. The aim of this work is to improve the efficiency of rail passenger services in the implementation of high-speed highways. One of the many areas of these measures is to improve the design of rail track solution nodes. Solutions track called complex devices and structures (koliyeprovodiv), for admission of rolling stock on the routes that intersect each other. The main design parameters koliyeprovidnoyi solutions include: - The angle of intersection lines (angle of intersection of interchange tracks); - Radius of circular curve in the plan; - Marks point frogs at the confluence (branching) tracks; - Length tracks in terms of interchange (length of the route); - The length of the transition curve; - The length of the line insertion between the ends of transition curves; - Steering bows; - The radius of vertical curve at the fracture site profile. Before modeling designer previously manually scheme consists junction (junction type is chosen, the number of tracks and switches, position curves stations tracks the availability circle of wire). Next, using the appropriate mathematical apparatus that is implemented on the computer, there are optimal design parameters of solutions. According to the simulation results obtained optimal design parameters of the solution. The results are used further in determining the economic benefit in selecting design solution to improve the design of a given circle leading solutions.
