在传统道路结构可靠度研究基础上，引入道路网络可靠度计算方法，提出道路网络结构可靠度研究方法.同时，在已建立的道路网络结构可靠度的基础上，以道路畅通可靠度为衡量标准，分析了道路发生拥堵时交通流量分配对道路网络结构可靠度的影响.

Based on traditional study of road structural reliability, this paper introduces a method for the calculation of road network reliability to provide a way of studying road network structural reliability. Meanwhile, in view of recent studies on reliability and mobility reliability, this paper analyzes the effect of traffic flow assignment during traffic congestion on road network reliability.
