Given many cities’ growing dependence on public rail transport, simple network disruptions can lead to widespread confusion and significant productivity loss to the society. Therefore, a systematic approach to develop efficient disruption response and minimize the negative impacts is required. In this paper, the authors develop a planning procedure to supplement a degraded urban mass rapid transit network through intelligent introduction of shuttle bus services in the disrupted area. The proposed method includes two important mechanisms, namely (1) using column generation to identify all beneficial bus routes, including those which might not be intuitively found, and (2) using a path-based multi-commodity flow formulation to select the best among these candidate bus routes. Finally, the method is applied to two disruption case studies defined using real-world data; the corresponding results confirmed the practicality of the proposed approach: (1) the procedure can be carried out efficiently, (2) introducing bus routes to the naive bridging services can easily yield significant improvement on commuters’ travel delay, (3) the distribution of commuters’ travel delay is improved considerably with an optimized response, and (4) many realistic operating constraints can be handled in planning process.
