Grigorov M. Information maintenance for modeling and control of transport flows in big cities

The dissertation work for scientific degree of the candidate of technical science in specialty 05.13.06 – Automatic control systems and progressive information technologies – Odessa national polytechnic university, Odessa, 2004. In the dissertation work the new solution of the important economical problem, this consists in development of methodological bases and tool modes for a construction of software for an automated control system of road driving. For a complicated urban road-street net and also introduction of algorithmic models, which rout the search for lowering the concentration of transport flows and economical losses, linked to it. An imitation movement model for the means of transport in an urban street-road net, which allows estimating their movement time between the city regions, is developed. The appropriateness of forming of the number of correspondences between the city regions is researched. It is determined, that on every way of going this number is inversely proportional to the timeof movement between these regions.
