路网期望交通延误指标近似计算的思路

Mentality of Approximate Calculation about The Expected Transportation Delays of The Road Network

文章基于网络的最可能状态和最重要状态,探讨对路网期望交通延误这一可靠性指标的近似计算思路。在介绍了几种近似计算路网可靠性指标的典型算法后,阐述了仅仅依据网络的最可能状态或最重要状态研究路网期望交通延误指标的不足。最后提出了进一步研究的方向。

Based on the most probable states and the most important states of the network, this article discusses the mentality of approximate calculating about the road network＇ s expected transportation delays which is a reliability index. After introducing several kinds of typical algorithms about approximate calculating of the road network＇ s reliability indexes, the article elaborates the insufficiency when we research into the road network＇ s expected transportation delays index only by the most probable states or the most important states of the network. The article finally proposes the further research direction.
