It is shown that the emergence of modern high-speed transport has led to cardinal social changes, namely to acceleration of urbanization, intensification of interregional and intercontinental migration flows, improving the quality of life. It is noted that directions and intensity of spatial displacements of people can be regarded as a social indicator aggregating individual ideas about attractiveness of certain places of residence. To quantify the spatial and temporal accessibility, the concept of «territory of isochronous accessibility» was introduced, and for socioeconomic assessments it was suggested to use a set of indicators as population size, gross domestic product, and the volume of production of services within the isochronous availability territory. Further acceleration of transportation speed implies both an increase in speed of transportation by different modes of transport, and elimination of time losses at the «junctions» between them, which should be supported by the development of multimodal logistics. Key words: transport communication, speed, society, humanity, urbanization, migration, space-time accessibility, territory of isochronous accessibility.
