Bi-level model predictive control for metro networks
Integration of timetables, passenger flows, and train speed profiles
This paper deals with the train scheduling problem for metro networks taking into account time-dependent passenger origin–destination demands and train speed profiles. The aim is to adjust train schedules online according to time-dependent passenger demands so that passenger sati

Real-Time Train Scheduling With Uncertain Passenger Flows
A Scenario-Based Distributed Model Predictive Control Approach
Real-time train scheduling is essential for passenger satisfaction in urban rail transit networks. This paper focuses on real-time train scheduling for urban rail transit networks considering uncertain time-dependent passenger origin-destination demands. First, a macroscopic pass

Timetable Scheduling for Passenger-Centric Urban Rail Networks
Model Predictive Control based on a Novel Absorption Model
Timetable scheduling plays a key role in daily operations of urban rail transit systems, as it determines the quality of service provided to passengers. In order to develop efficient timetable scheduling methods, it is necessary to develop a proper model to integrate timetable-re

Real-time timetable scheduling is an effective way to improve passenger satisfaction and to reduce operational costs in urban rail transit networks. In this paper, a novel passenger-oriented network model is developed for real-time timetable scheduling that can model time-depende

Effective timetable scheduling strategies are essential for passenger satisfaction in urban rail transit networks. Most existing passenger-centric timetable scheduling approaches generate a timetable according to deterministic passenger origin-destination (OD) demands. As passeng

The integration of autonomous vehicles and on-demand customized bus
systems is expected to be beneficial for responding to real-time
demands. This paper investigates the autonomous customized bus (ACB)
system that leverages passenger demand prediction to enhance service

Timetables determine the service quality for passengers and the energy
consumption of trains in metro systems. In metro networks, a timetable
can be made by designing train departure frequencies for different
periods of the day, which is typically formulated as a mixed-integer

Railway networks are subjected to disruptions on a daily basis, which may make the timetable unimplementable, which in its turn may significantly influence passenger satisfaction. In practice, train dispatchers are responsible for mitigating the influence of disruptions, such as

The railway timetable rescheduling problem is a challenging problem in both industry and academia. It is required to calculate a feasible and relatively good timetable within a limited time to reduce the negative impact of disturbances or disruptions. The railway timetable resche
