Abstract:

Bus scheduling plays a key role on the operation of the stereoscopic and function- integrated depot (SFID or stereoscopic bus depot, SBD). Being different from previous bus scheduling, bus scheduling for SBD needs to determine the parking location, departure time, and driving path. This study focuses on the SBD bus scheduling considering the attributes of buses like departure in the morning and return at night. The condition of vehicle interweaving is also considered in the analysis. An optimization model is developed to solve the bus scheduling scheme based on the integer programming, and the weaving times between buses are set as the objectives of the model. The results indicate that there are two modes of bus scheduling for the SBD: the mode that dispatches buses at the same floor, and the mode that dispatches buses at different floors. The different- floor dispatching mode performs better than the same-floor dispatching mode. The interweaving condition is the doubleoverlapping of route space and out time. The case study was also conducted to verify the accuracy of the results and the feasibility of the proposed method.
