摘要
We use the model with the consideration of the traffic study the relationship between the traffic risk coefficient interruption probability （Physica A 387（2008）6845） to and the traffic interruption probability. The analytical and numerical results show that the traffic interruption probability will reduce the traffic risk coefficient and that the reduction is related to the density, which shows that this model can improve traffic security.
