A reliability-based transit assignment in schedule-based networks with uncertainties

This paper proposes a reliability-based transit assignment model in schedule-based transit networks with uncertainties arising from the randomness of transit schedule and passenger demand. A reliability-based transit user equilibrium condition is defined on the basis of the concept of reliable effective travel cost (RETC), which involves the mean and variance of travel cost as well as the boarding reliability of the transit route. The proposed model is formulated as an equivalent variational inequality (VI) problem and solved by a column generation based solution algorithm. Numerical examples on a simple transit network are used to illustrate the essential ideas and contributions of the proposed model. The numerical results show that the schedule-based approach and the proposed concept of RETC are more realistic to capture the impact of different levels of crowding at transit stops and risk-aversion degrees on the route choice behavior of passengers. The proposed model can be applied to evaluate the impact of an Advanced Public Transport Information System (APTIS) on risk-adverse passengers' decision-making in congested transit networks with uncertainties.
