A Train Service Planning Model with Dynamic Demand for Intercity Railway Systems

抄録

The journey time of intercity trains is usually more than hours. The train dispatched at its departure station may not be able to serve the passengers during the same hour at downstream stations. In addition, intercity trains usually consist of various stopping patterns. Consequently, typical method for determining train service plans based on maximum passenger load and train capacity is inapplicable for such systems. For these reasons, this paper develops a mathematical model for generating optimal train service plans for intercity railways, taking into account the dynamics of train movements and the transfer of unserved passengers. This model combines operator's revenue, operating cost, and users' travel-time cost as its objective. The operational requirements are formulated as the constraints. The Taiwan High Speed Rail is taken as an example to test the model. The case study shows that the model is very efficient and is very flexible for different operation strategies.
