Normally road network planners only consider benefits of decreasing travel times by constructing new expressways in estimating time related economic benefits. However, it has become more important to evaluate the reliability of road networks since there are increasing needs to reduce the risk of arriving late at the destination. The model incorporates the probabilistic characteristics of travel times associated with the designated arriving time. An example of applying the model to the Kyoto-Osaka area is also demonstrated. 1 Introduction The reliability of road network has become more important, since the time value of people
