Abstract

The effects of the damaged car evacuation (P(exit)) and the collision (P(col)) probabilities on the traffic flow behavior of a car accident are investigated in the one-dimensional cellular automaton Nagel-Schreckenberg model, with injecting (alpha) and extracting (beta) rates in parallel dynamics. In this study, we suppose that the car involved in collision is evacuated from the road, with an exit probability P(exit). It is found that the behaviors of density, current, and (alpha,beta) phase diagram topology depend strongly on the values of P(exit) and P(col). Indeed, the high-density region shrinks when increasing P(exit). Moreover, the critical value alpha(c)(beta), at which the low-density-high-density transition occurs, increases when increasing P(col) and/or P(exit). Furthermore, the critical value at which the transition high-density-low-density occurs decreases when increasing beta and increases with alpha.
