%X Considering the effects of different factors on the stochastic delay probability , we have classified the delay probability into three cases. The first case, cor responding to the deceleration state, has a large delay probability if anticipan t veloc ity is larger than the gap between the successive cars. The second one, correspo nding to the leader following stably, has an intermediate delay probability if t he anticipant velocity is equal to the gap. The last is the one with acceleratio n with the minimum delay probability. The fundamental diagram obtained by the nu merical simulation shows the different properties compared with that by the NaSc h model, in which there exist two different jamming regions corresponding to the coexistent congestion and jamming with different properties of shock wave.
