Determining Alternative Train ODs under Cyclic Train Operation Mode for a Large-scale Rail Network

摘要

Although the cyclic train operation mode has been widely applied in many small-scale rail networks, it is more practical for a part of trains to use this mode under large-scale rail networks with complex structure and diverse travel demand. For a large-scale rail network, this paper analyzes how to determine alternative train ODs (origins and destinations). Specifically, we discuss the main elements, principles and methods of determination of cyclic and acyclic train ODs of the rail network. The proposed method is applied to a high-speed rail network in China to obtain alternative train ODs. The resulted scheme of train ODs can provide an important basis for designing a cyclic line plan.
