Assessment of transit networks is usually based on a deterministic point of view by assuming that all components of the system perform as planned. In reality however, a large number of regular and irregular variations influences transit services such as variations in demand, service operation, and infrastructure availability. The question is how these phenomena might be taken into account in the transit network assessments. In this paper, an extended network assessment criterion is introduced to evaluate transit service performance in the stochastic perspective. Accordingly a simulation tool is used to assess a set of hypothetical urban transit networks. This paper evaluates and compare different transit networks for a medium city size in the classical deterministic view as well as with the more realistic stochastic approach. The findings clearly show that considering service reliability may lead to different assessment criteria, and different plan options; not only for transit service networks, but also for transit infrastructure networks.
