For medium-sized cities in developing countries like China, a new operation problem of bus corridors emerges with the formation of multi-cores land structure. More branch lines stretched from peripheral areas connect with or even converge into corridors and form multiple transfer stations. Because reconstructing facilities and improving network structures are not applicable to gradual growth and feature changes of demands, coordinating the frequencies of bus lines will be an effective way to keep transport efficiency and service quality. Not only should great corridor's inner transport demands be met through the coordination procedure but also complex transfer demands, along with the consideration of corridors' capacity constraints and vehicle capacity constraints. In this paper, a mixed integer-nonlinear programming model is developed to optimize the frequencies of the corridor bus lines, assuming a known trip matrix. The method was applied to Renmin corridor in Jiangyin City of China. In the case, the coordinated frequency scheme improved the Transportation Efficiency Factor of the corridor by 5% while keeping a smooth running order through adjusting the capability saturation of sections and stations. The average waiting time was not only optimized in theory, but also reduced in practice while the risks of unsuccessful boarding were controlled. In addition, an analysis was done to judge the valid scope of the frequency scheme when non-inner demands fluctuated, and it was found that until the non-inner demands taken by branch lines increased by 25%, the frequency scheme would continue be applied.
