Study on computation of urban traffic network connectivity reliability
城市交通网络连通可靠度计算研究

This paper considersed the random variation of the operational state at the roads' section and intersection, taking the road saturation as the main factor. It improved the formula of road section connectivity reliability, and provided the measurement of the intersection reliability, combining sections, intersections reliability especially the reliability of the intersection of different steering, it designed a spanning tree algorithm to find a disjoint path of the transport network, and then quickly calculated any OD connectivity reliability of transportation network. The example shows that the intersections' reliability impacts the urban transportation network connectivity reliability. The proposed algorithm has a certain value and referenced significance.
