For mathematic description of traffic stream use of mathematic apparatus, that is used in theory of probability for Markov`s random process. Use of Mar-kov`s successions allows to set a problem of determining the probability of find-ing the traffic stream in any condition, as well as beingwith the help of Kolmogo-rov`s equations finding the possibility of denial, the possibility of maintenance, as well as absolute carrying capacity of the system.

We solve the problem of free vertical oscillations of the car, taking place in parallel to the plane of symmetry. We find conditions under which the only pos-sible vertical oscillation, or only the angular oscillations around the center of gravity. We find conditions that reduce the possibility of resonance.
