Specific Features of Building Transport Infrastructure in Megacities

The paper analyzes specific features of the transport infrastructure building in modern megacities. Recently, the issues of transport infrastructure built in many megacities and cities associated with the comprehensive solution to urban and transport problems have become noticeably more relevant. This study uses a systemic approach that helped to show continuity, scale and social orientation of the transport infrastructure in megacities. The main problems and achievements in solving transport problems in large cities are identified. The issue of the role and importance of better transport infrastructure development in megacities is considered through the prism of complex and sometimes conflicting relations between transport and environment. The current transport infrastructure challenges and problems, new opportunities and benchmarks in achieving maximum efficiency of a particular mode of transport under different conditions are indicated. Special focus is placed on the possibilities of providing convenient and shortest travelling routes between all parts of the city, as well as between external transport routes. The content of the city transport network is described and characterized consisting of a set of streets and traffic routes served by various forms of city transport, underground, ground, above-ground transport lines connected with the street network in part or not connected with it at all, for example, city railways, overhead roads, metro, monorail roads.
