The Single-Line Design Problem for Demand-Adaptive Transit Systems: A Modeling Framework and Decomposition Approach for the Stationary-Demand Case

When demand for transportation is low or sparse, traditional transit cannot provide efficient and good-quality service, because of its fixed structure. For this reason, mass evolving toward some degree flexibility. Although the extension Dial-a-Ride systems to general public meets such need adaptability, it presents several drawbacks mostly related their extreme Consequently, new alternatives, as demand-adaptive (DASs), combining characteristics from both Dial-a-Ride, have been introduced. twofold nature, DASs require careful planning. We focus on tactical aspects planning process by formalizing single-line DAS design problem with stationary proposing two alternative hierarchical decomposition approaches solution. The main motivation behind work a methodology suitable be used tool build plan in real-life conditions. an experimental study where proposed methods are compared behavior analyzed when altering parameters. Furthermore, we test versatility our variety situation that may encountered
