Simulation has been performed for traffic flow in two-dimensional cellular autotaaaton modelsincluding cars with unequal velocities: the northbottnd cars with a normal speed and the eastbound cars with a high speed. For the eastbound high speed cars, two models are considered. Inthe model I, the intrinsic velocity is defined for all eastbound cars. In the model II, the rrtaxirnumvelocity, acceleration and deceleration of the cars are taken into account. It has turned out thattwo new phases appear between the free-nuoving phase and the global jamming phase in bothmodels. One is the one-sided blocking phase where the northbound cars block the high speedeastbound cars. Another is the mutual blocking phase where the cars on both roads are mutuallyblocked. The rnean velocity of the cars and the size of the local jam are obtained.
