ABSTRACT. The optimal criterion concerning NGV-RCSs locations in the cities and the mathematical model of vehicle flow distribution on the road network of cities were analysed. It has been determined that optimization of NGV-RCS locations is a multi-criterion problem having no definite solution. The criterion for solving the problem can be the number of vehicle flows within street and road network which requires solving the problem of forecast;, in turn, the forecasting problem consists of two subproblems formation of vehicle flows and optimization of vehicle flow distribution within street and road network. The problems are of NP type; moreover, there are no algorithms making it possible to obtain accurate solutions.
Introduction. All known concepts of transport and road system of the world cities involve the improvement of ecological and sanitary and epidemiological conditions at the expense of solving both ecological and energy problems. Implementations of the measures are complicated due to scientific difficulties connected with uncertainty of effect by components of transport systems; among other things that concerns the effect of location of NGV-filling compressor stations (NGV-RCSs) on the efficiency of transport systems and extraordinary labour intensity in the process of the parameters determination in the context of available street and road networks. Thus, solving the problem of the improvement of efficiency of transport systems of cities at the expense of decrease in environmental pollution and reduction in the above fuel consumption reduction in terms of commercial success of projects concerning modernization of transport systems of cities is important practical task. The problem can be solved providing that important problem connected with formation of automobile transport infrastructure in cities is solved. Statement of the problem. Both theory and practice of automobile transport infrastructure formation in cities pays much attention to determination of rational quantity and location of car services, gasoline stations, and NGV-filling compressor stations (NGV-RCSs). In this context, opinions of researchers as for parameters concerning estimation of alternatives and ways to solve the problem vary. The problem concerning optimization of development decisions and transport infrastructure location within territory of a city was analysed intensely both in Ukraine and abroad. In the context of automobile transport, the following may be listed as principal directions in the field: the development of street and road network and components of transport infrastructure (all types of filling stations, car services, garages etc.).
