The article considers the technological aspects of organization of passenger and baggage transportation by taxi cabs in megacities, referring particularly to the practices of a number of countries.The authors analyze l e g a l regulation and technological development of taxi services in Moscow metropolitan area, including the current system for organizing the work of passenger taxi dispatch services taking into account centralization of information flows in a single city system.An analysis of methods for planning placement of taxi ranks shows that outdated approaches are used to solve that problem without using modern information and communication technologies. In this regard, the methodological foundations of planning the organization of taxi ranks based on geoinformation data in the city of Moscow are proposed.The studies and analysis made it possible to determine relevance and feasibility of existing and justification for planning of new taxi ranks, taking into account the requirements for rationality of location of taxi ranks from the point of view of ensuring a small walking distance for passengers, as well as reducing time of car delivery. The proposed method using accurate coordinates transmitted by the largest taxi dispatch service companies into the Unified Regional Navigation and Information System of the city of Moscow allows to implement these requirements.
