为了尽可能地减少事故条件下的交通延误,预防二次交通事故的发生,对事故条件下高速公路路网的运行效率进行评估是十分必要的。选择时间可靠性作为评价指标,对路网处于常态下、突发事故中及实施紧急交通组织后的指标值进行比较,并通过对比分析得出事故对交通的影响程度、紧急交通组织的效果及交通恢复程度指标,为事故条件下路网交通组织方案优化提供科学依据。
In order to reduce the traffic delay under accident conditions as much as possible and prevent the occurrence of secondary traffic accidents, it is necessary to evaluate the operation efficiency of freeway road network under accident conditions. Choosing the time reliability as the evaluation index, compares the index value of the road network under the normal condition, emergency accident and the implementation of emergency traffic organization, and draws the comparative analysis of the impact of the accident on the traffic, the effect of the emergency traffic organization and The index of traffic recovery degree provides a scientific basis for the optimization of traffic network organization under accident conditions.
