The problems connected to traffic of megacities are submitted the world and Russia are presented. The review of the basic ideas and methods in area of mathematical modeling of transport streams is given. The mathematical model of formation of queue is given at one-strip adjustable crossroads with one-strip movement. The average length of queue at a crossroads on the given strip is found. Perspective directions of the further researches are marked.

Mathematical modelling in actual problems of science and technics
