本文考虑了两类依赖于交通流日变化的区域路网可靠性测度。一个度量值表示相关网络上每个OD对之间的连接概率。另一个是OD行程时间的准确程度。在OD需求随机变化的假设下，采用增量分配法模拟路段交通量的变化，得到路段连通概率和P. D。F.旅行时间。以四国地区的实际大规模道路网为例，对可靠性指标进行了检验。结果表明，该方法在公路网评价中具有较好的应用价值。
This paper considers two types of reliability measures of regional road network depending on the daily variance of traffic flow. The one measure represents the probability of connections between each OD pair on the concerned network. The other shows the degree of accuracy of OD travel time. Assuming the stochastic variation of OD demand, the Incremental Assignment method is employed in order to simulate the link traffic variance, which derives both the probability of link connection and the P. D. F. of travel time. Reliability measures are examined for actual large scale road networks in Shikoku Area. The results verify that the proposed method is available in the application to the road network evaluation.
