МОДЕЛЮВАННЯ ОПТИМІЗАЦІЇ МІСЬКОЇ ТРАНСПОРТНОЇ МЕРЕЖІ В ІНТЕГРОВАНИХ ТРАНСПОРТНИХ СИСТЕМАХ

Abstract

Abstract In world practice, one of the main features of integrated transport systems, is the delivery of goods "door-to-door", which is impossible without the road transport is being used at the final stage of transportation. Today, the situation on the Ukrainian roads has a negative trend in terms of traffic jams and accidents, which creates a risk of delay or damage to freight during the transportation process. The problem is how to optimize the urban transport network to meet the growing demand for transportation and reduce traffic congestion. Purpose. Investigate the root causes of traffic congestion and develop a tool in order to optimize the city network on the example of a traffic interchange. Analytical and experimental with the use of computer 3D-simulation. For a practical demonstration, a model of one of the most problematic, from the point of view of traffic jams, transport interchanges in Kyiv, was developed. An optimization experiment was conducted, which demonstrated an increase in interchange capacity by 26,2% and reduction in average transportation time by 60, 47%. It is a difficult task to optimizing the transport network, because if you conduct an experiment with a real system, any changes could be catastrophic. In addition, it is necessary to anticipate the growth of traffic, take into account the economic, territorial and industrial characteristics of settlements. The research clearly demonstrates the possibilities of simulation computer modeling in this aspect. The purposed solution allows to optimize the city transport network without significant investment, and could reduce the risk of accidents, financial and time costs for transportation of goods by city in the global aspect. Keywords: freight transport, intersections, integrated transport systems, urban transport network, optimization, imitation modeling.
