Modeling of segregation of two-lane flow of particles

We consider a stochastic model of segregation (departing) of flow of particles into two components. One-sided movement of particles on two-lane field of cells occurs. Flow departing occurs on a transit section. Each particle tends to transit successfully to the lane which it has to continue its movement. We give an example of use of the developed model for an investigation of flow of cars. We found the estimate of the necessary length of transit part of the road before crossing.
