The features of the port transport and technological systems from the point of choosing the location of the distribution terminal, as the damper areas on the directions of export cargo. The authors propose a modification values of the coefficient of proportionality fractional power function the gravitational model and introduced the term "measure transport gravity" to evaluate options for placement of distribution terminals in the transport network.

Keywords: Port rail transport technology system, cargo traffic, distribution terminal, graph theory, a modified gravity model, a measure of the transport of gravitation factor saturation network connections
