A five-module concept of developing a system for effective management of urban passenger transport (UPT) of a megacity has been developed. The data sources are the topology of the route network, the traffic schedule, the navigation system of traffic and payments transactions. The modules include preliminary processing of the initial data of the UPT, the implementation of algorithms for constructing optimal routes, the identification of the correspondence matrix of passenger flow, the modeling of the movement of passenger flow with a known correspondence matrix along the optimal routes, obtaining quantitative estimates of the current UPT network, and lastly developing a mobile information system for informing the passenger about possible variants of its route. The necessity of a correspondence matrix is shown when there is a reasonable variant of transportation of the population. The concept assumes that the passenger intuitively chooses the best route for their trip. The module of optimal routes is the key module of the whole concept.
