This paper proposes a novel cooperative cruise control strategy to jointly optimize the energy consumption and ride comfort for multiple high-speed trains. The is constructed by combining consensus algorithm potential function achieve synchronization of train speed keep safe tracking interval. A multi-objective optimal trains constituted following error, comfort. non-dominated quick sorting (NS...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...
The publication deals with the problem of effect interference movement “preceding” train on “following” in case efforts to reduce distance between trains a moving block interval. paper presents results simulations for ED250 type set 135 traffic situations: three contexts reducing speed train, five variants method controlling and nine initial distances these trains. confirmed possibility gaining...
OBJECTIVE To analyze the status of occupational stress in different types of train drivers. METHODS By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual fa...
With the rapid development of China's high-speed railway (HSR), there are also many problems. For example, in classification and calculation HSR transportation costs, is a lack reasonable cost statistical methods. There types train currently running on (mainly G D trains). differences speed, load energy consumption different trains. The resulting infrastructure usage costs vary. However, all cl...
The energy consumption modeling and the optimization solution for the traction control of high-speed trains are addressed in this paper. Based on the analysis of the operation process, an improved train traction analysis with the multi-mass modeling approach is presented, and the corresponding energy consumption model is investigated. By considering the issues of the passenger comfort and trave...
Tools for estimating end-to-end available bandwidth (AB) send out a train of packets and observe how inter-packet gaps change over a given network path. In ultra-high speed networks, the fine inter-packet gaps are fairly susceptible to noise introduced by transient queuing and bursty cross-traffic. Past work uses smoothing heuristics to alleviate the impact of noise, but at the cost of requirin...
