SYSTEM ANALYSIS OF TRANSPORT INFRASTRUCTURE FACILITIES IN A GEOINFORMATION ENVIRONMENT

Muratov Igor V.

The article considers the system analysis of transport infrastructure facilities in a geoinformation environment. It is noted that the definition of the tasks and functions of the GIS system allows developing software modules (plugins) that allow working not only with cartographic and geodata, but also with specialized information that is attached to the map. An optimal list of plug-ins is presented that allows for a system analysis of transport infrastructure in a GIS. It is concluded that the analysis of transport infrastructure facilities in a GIS system, due to the availability of effective tools, allows for an analysis of development, natural obstacles to movement, which allows for the implementation of transport zoning of the city; analysis of factors determining transport accessibility and needs of specific areas of the city, assessment of the efficiency of the transport network, planning its development (taking into account the excess of the length of the most optimal route by more than 40%), build optimal routes along streets and roads taking into account permitted directions of movement, turns, street capacity, etc., analysis, assessment and informing the population and specialists about accidents on the roads, visualize a geographic map for the population and transport.
