Abstract
For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).The studies were carried out with financial support of the Ministry of Education and Science of the Russian Federation within the framework of the project under contract No. 02.G25.31.0006 dated 12.02.2013 (Decree of the Government of the Russian Federation No. 218 dated April 9, 2010). ABSTRACT The main factor that forms the perturbation, acting on the car in operating conditions, is the speed of movement. Analytical studies of operational properties and reliability indicators are based on the characteristics of traffic - distribution of runs and speed, in some cases obsolete, or incomplete and not correlated with the characteristics of the macro profile of traffic routes. The data on research of characteristics of the macro profile of country roads of the central Russia are given, their classification is offered. Stationary arrays of random values of relative mileages are allocated and the approximation of random speed distributions by analytic dependences is performed. The obtained results allow to simulate the car movement at early stages of design works and to improve the accuracy of the evaluation of parameters and characteristics studied. Keywords: car, perturbation, macro profile, analytical studies, theoretical methods, experiment, approximation, distribution, mileage, speed, projection, motion model.
