Disruptions in public transit systems can have significant impacts on agency and passenger needs. Therefore, it is crucial to implement new transit policies to address these disruptions and to ensure efficient and reliable transit services. This study proposes a framework to assess alternative bus operating strategies to adapt with different disruptions to public transit systems. Conventional all-stop systems, visiting all the stops along a bus corridor, are compared against three alternative operational schemes: Skip-stop, express-local schemes with stop-skipping designs, and on-demand service with a fixed route but flexible stopping patterns, are compared to find the most efficient bus operating service under various circumstances. We developed an optimization model based on the total generalized system cost for each operating strategy using continuous approximation techniques and extended the previous models by comparing a wider range of alternative services and model flexibility to evaluate the optimum system in response to different disruptions. Different factors, such as the level of demand, demand patterns, and sensitivity to various components of transit trips for passengers and the operator, including crowding, denied boarding costs, and fleet constraints, are considered. We found that, given a different disruption scenario, demand, and travel patterns, the most efficient service can vary significantly between on-demand, all-stop, skip-stop, and express-local services. As such, it is suggested that the service scheme be chosen more adaptively by employing such frameworks.
