    "abstract": "A system of identical cars on a single-lane road is treated as a\nmicrocanonical and canonical ensemble. Behaviour of the cars is characterized\nby the probability of car velocity as a function of distance and velocity of\nthe car ahead. The calculations a performed on a discrete 1D lattice with\ndiscrete car velocities.\n  Probability of total velocity of a group of cars as a function of density is\ncalculated in microcanonical approach. For a canonical ensemble, fluctuations\nof car density as a function of total velocity is found. Phase transitions\nbetween free and jammed flow for large deceleration rate of cars and formation\nof queues of cars with the same velocity for low deceleration rate are\ndescribed.",
