Численное моделирование процесса роста кристаллов из расплавов на вращающемся диске

This paper proposes a general method for modeling traffic flow based on the use of Markov processes, different from the known methods and flow models as follows: fundamentals of the method applied to modeling traffic on roads with different number of lanes; number of velocity groups, the characteristics of which are studied move-ment is not limited; virtually unlimited range of variation of road conditions, traffic flow determines the mode; simulation results are not only the mean flow characteristics, but also in the flow characteristics of the motion of individual vehicles and individual stream type groups, which further Used To increase the reliability and accuracy of the figures of the car; input for the simulation of movement of cars in the flow simulation results are free mo-tion. This integrated approach allows to take into account the dynamics of the towing vehicle speed properties, extended the scope of the flow ; with substantial completeness reflected in vehicle operating characteristics of the parameters of the plan longitudinal and transverse profiles, the type and amount of pavement, road conditions. Using the method of Markov processes made the transition from a small number of velocity groups (2, 3 groups) to a continuous velocity distribution. There by achieved greater generality in the formation of the main provisions of the model. Some practical research model car traffic flow on a one-lane roads and two-lane roads (II–IV cate-gories).
