The formation of optimal trajectories of transport routes will significantly improve the quality of transport services and transport connections for mass construction of various types of overpasses, which should have a positive impact on the economic component of both freight and passenger traffic, and contribute to building quality infrastructure in our country.
In a practical sense, modeling the optimal trajectories of different types of transport, taking into account their geometric parameters will allow more accurate coordination of design solutions with natural terrain and overcoming artificial obstacles, which is now one of the urgent requirements in large-scale construction and reconstruction of transport infrastructure.
The result of the research performed in the work is the solution of an urgent scientific and technical problem of improving the quality of design and reducing the cost of transport connections by determining the optimal trajectory of overpasses. The work is devoted to the development of theoretical bases of geometric modeling of optimal discrete trajectories of transport networks on the plane, specially discretely presented surfaces from the point of view of the optimal (minimum) way of connection for implementation in the design process.
In the scientific sense, these developments set the direction for further research in the field of discrete surface modeling in the field of optimal tracing for different types of transport, and in practice - serve as a basis for improving the design of overpasses in spatial planning of roads, namely: – geometrical parameters, characteristic restrictions for different types of transport networks (railway, highway, monotransport, pipelines, etc.) are investigated and determined; – the geometrical model for definition of optimum discrete trajectories of ways of connections by means of optimization methods for a plane and a flat relief taking into account obstacles is offered;
– the technique of construction of a discrete surface depending on natural obstacles which is used for an optimum transport network is improved;
– the technique and algorithm of definition of optimum trajectories of transport networks by means of optimization methods for a non-flat relief taking into account obstacles are offered; – the concept of optimization of overpasses (railway, highway, monotransport, pipelines, etc.) on a non-flat relief taking into account obstacles with use of neural networks is offered; – developed a method of using different types of optimization problems to determine the optimal ways.
The practical significance of the results: Engineering automated interactive method of designing the optimal trajectory of transport connections on the terrain and plane has been developed. The programs for definition of an optimum discrete trajectory of ways of communication on criterion of minimization of length and cost and increase of economy of transport networks and application in designing are created. The methodological bases for determining the optimal trajectory of movement among artificial obstacles have been improved. The results of scientific researches on optimization of a trajectory of a transport way in educational process and project practice are introduced.
