In this article, we investigate the velocity-clearance relation of vehicles in CA models for traffic flow using a calibration of the cell size (length) which we already proposed. We can mimic a more realistic behaviour of vehicles in traffic flow changing the cell size according to the density of particles in cellular automaton models. As a result, the velocity of particles in the rule-184 cellular-automaton model becomes dependent on the clearance, i.e., the distance to the next particle in front (in the right-hand side). Also, we show that the calibration is valid in that it reproduces a realistic flow-density diagram.
