This paper studies the routing strategy in a transit network with partial online information at stops. By partial online information, the authors mean the arrival time of the next transit vehicle is available only for a subset of all lines at a stop. Existing studies, which assume either no information or full information, are shown to be special cases of the partial information case. The authors propose a new routing strategy in this general case and develop closed form formula for computing expected waiting time and line boarding probabilities. The problem of determining the attractive set is also discussed for each of the three information cases. In particular, a new heuristic method is developed to generate the attractive set in the partial information case. The authors show that the proposed heuristic will never lead to a solution worse than that obtained in the no information case. Numerical experiments are conducted to illustrate the impact of information availability on passengers’ total travel time and transit line load distributions.
