One of the priorities of the state policy in the field of transport infrastructure development is the modernization of the Russian seaport infrastructure, the creation of modern competitive transport hubs and other architectural objects with a complex functional and planning structure. This article is devoted to the study of functional and technological solutions of modern sea passenger terminals and the requirements to these solutions taking into account the interests of consumers, including people with limited mobility. The functional diagram of the passenger building of the seaport and types of pre-trip passenger training operations are given. It is shown that the efficient decisions of optimizing functional , technological, architectural and planning solutions of seaport passenger terminals is possible with the use of modern IT and technologies for passenger handling. From the perspective of system approach the tasks of functional and technological solutions’ optimization are aimed at achieving the high quality of architectural environment and are the mathematical programming tasks.
