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 ...

Positive Train Control With Dynamic Headway Based on an Active Communication System
IEEE Transactions on Intelligent Transportation Systems, 2015Safety, capacity, and timely schedules are some of the most crucial objectives in railway operations. Positive train control (PTC) is a concept whose goal is to improve the safety and efficiency of railway operations by using advanced information technologies.

Impact of wireless communication delay on train headway of Communication Based Train Control system
2016 IEEE 19th International Conference on Intelligent Transportation Systems (ITSC), 2016With the rapid growth of capacity demand of railways around the world, Communication Based Train Control (CBTC) system, which is usually used in moving block signaling system to shorten the headway, is adopted by more and more countries. The railway operator in Beijing, the Beijing Subway, is no exception.

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...

Research on the optimization of train headway for the high-speed railway network
ICSSSM11, 2011The difference of speed, headway and stop pattern increases the difficulty of the calculation & evaluation for railway capacity, for which the headway is the basis. It's the critical point that how to use the obtained minimum train headway. By analyzing the likely delay and its propagation during train run under the organized transportation mode, this ...

Effect of Train Headway on Voltage Collapse in High-Speed AC Railways
2012 Asia-Pacific Power and Energy Engineering Conference, 2012Minimum headway is one of key factors in railway system operation. Most railway passengers normally expect that a next train will arrive at their platform as soon as possible. Due to economical and safety aspects, headway between two consecutive trains must be kept over its critical value.

Train trajectory optimization with dynamic headway
2017 36th Chinese Control Conference (CCC), 2017The trajectory optimization with dynamic headway for high-speed trains plays an important role in railway operations with the increasing passenger flow. Safety, punctuality, energy saving and comfort are some of the most crucial objectives that are considered in train tracking process in this paper.

Stochastic approximation to the effects of headways on knock-on delays of trains
Transportation Research Part B: Methodological, 1994Abstract In train planning and timetabling, the trip time on each link is assumed to depend on the type of train and characteristics of the link, but is usually treated as independent of the time interval (headway) between trains. However, in practice trains are subject to delays from a variety of causes, and since normally they are not allowed to ...

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.
