This study focuses on a single line transit scheduling problem, considering the characteristics of the unbalanced two-way and one-way distribution of passenger demand, a bi-level programming model of transit mixed scheduling and procurement is proposed. The relationship between the mixed scheduling and its procurement scheme was analyzed from the viewpoint of system theory. The upper-level model takes the minimal bus purchase expense and operation cost as the targets, and the required standard of service as the constraint. The lower-level model simultaneously optimizes the frequencies of inter-zone buses and two-way whole-line buses as well as the turning location of inter-zone buses in order to minimize the passenger travel time costs. For comparison, the model for single scheduling and procurement was also studied. Furthermore, numerical example and demand sensitivity analysis were given to verify the effectiveness and advantage of the proposed model. In addition, data comparison and analysis show that the mixed scheduling can save the transport capacity, passenger travel time and the operation cost under unbalanced demand situations. The more severe the unbalanced demand, the more superior the proposed model with the same bus procurement scheme.
