Optimization of Multiperiod Mixed Train Schedule on High-Speed Railway

Train Schedule Optimization in Public

Attractive train schedules are quite important for the success of public rail transport. We consider schedules which are repeated after some xed time period. Periodicity is a well accepted, convenient attribute of all major railroad systems. Since trains share the public railroad network, we have to handle many connicting demands. Increasing competition from transportation alternatives as well ...

A discrete-event optimization framework for mixed-speed train timetabling problem

Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...

Optimization of Handover Algorithms in LTE High-speed Railway networks

This paper introduces two kinds of handover algorithms that adjust the handover (HO) parameters of LTE (Long-Term Evolution) eNodeB (evolved NodeB) to improve the overall network performance and diminish negative effects. The focus is on the impact that two kinds of handover algorithms compare to A3 event based on the optimization of hysteresis and time-to-trigger in the different velocity envi...
