New Headway-Based Analytical Capacity Model Considering Heterogeneous Train Traffic
Journal of Transportation Engineering, Part A: Systems, 2020AbstractAssessing the railway capacity of a rail network wherein a few types of trains operate with various halting patterns is very difficult, because the headway greatly varies depending on the o...

Optimization of Train Headway in Automatic Train Control System
2018 24th Asia-Pacific Conference on Communications (APCC), 2018Since urban rail unmanned train is considered as one of the core technologies of Intelligent Transportation System (ITS) , how to shorten the train headway as the driven interval between unmanned trains properly is still a challenge in Communications Based Train Control (CBTC) system.

Cooperative Control for Train Headway Adjustment in Railway Traffic
IFAC Proceedings Volumes, 2013Abstract Train headway adjustment can optimize train operation and decrease train delay. The main objective of this work is to design a controller for a train fleet that can adjust their headways in a cooperative way. We proposed a train headway adjustment model based on linear quadratic optimal control.

Optimal Train Size and Headway for Urban Rail Transit System
Applied Mechanics and Materials, 2012An analytical model and a solution procedure are proposed to optimize train size and headway for an urban rail transit system wherein passengers demand is assumed to be sensitive to fare and the level of service, in terms of load factor and waiting time.

Train cooperative control for headway adjustment in high-speed railways
2017 IEEE Intelligent Vehicles Symposium (IV), 2017In high-speed railways equipped with advanced train control systems, the train-to-train or train-to-ground communication technologies enable the trains to follow their former trains with a constant headway. Due to some disturbances (e.g., weather condition, train re-routing), the train following headway may be inconsistent between successive trains ...

Optimal train schedule with headway and passenger flow dynamic models
2013 IEEE International Conference on Intelligent Rail Transportation Proceedings, 2013This paper proposes an optimization method of train schedule for metro line, which will make the timetable, including train dwell time, in line with passenger demand. This method is also provide space for timetable improvement in robustness and energy-saving.

Study on train headway models for super-speed maglev system
Proceedings of the 2003 IEEE International Conference on Intelligent Transportation Systems, 2004In this paper, new headway models are established by analyzing the more complex operations happening in a long-distance corridor line of the transrapid super-speed maglev system (TSMS). The variation law in the minimum allowable trains headway is analyzed.
