Abstract: We study a simple one lane cellular automaton, based upon the well-known Nagel-Schreckenberg model, and examine the effect of disorder caused by some defects (deceleration sites, temporary stop sites and presence of slow cars) in such a system. We point out the important parameters defining the shape of the fundamental diagram for the NaSch model and compare it to that of one with sites or particles disorder, showing a new mode of interactions between vehicles. Important differences in the flow behavior between these types of defects and their impact on the occurrence of congestions have been established.
