This article discusses the reliable space–time prisms under travel time uncertainty and extends it to congested road networks. It first defines it as the set of space–time locations where an individual can participate in an activity and return to his or her destination with a given on-time arrival probability. Then, a case study using real-world traffic information in Wuhan, China, is carried out to demonstrate the applicability of the proposed prism model. The results indicate that the proposed prism model can represent well individuals’ space–time taking into account various on-time arrival probability concerns
