The subject of the research is study potential piggyback transportation on basis multimodal terminal and warehouse infrastructure Kaliningrad railway. relevance topic determined by intensification international trade, which requires simplification receiving dispatching transfer operations in a complex logistics system for delivery goods use intermodal transport modules to speed up listed operat...
ac railway traction loads are usually huge single phase loads. as a result, a significant amount of negative sequence current (nsc) is injected into utility grid. moreover, harmonics and consumption ofreactive power are further power quality problems that the supply network is encountering. in this paper, acompensation strategy with the aid of railway power conditioner (rpc) is proposed to over...
the passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. a line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. a new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....
Risk management is an important part of system assurance and it is widely used in safety-related system. Railway signal system is one kind of safety-related system and its most important goal is to guarantee the safety of railway system. The method based on risk management can find and solve the security issues of railway signal system more effectively. This paper introduces the basic conceptio...
Railway traffic has increased over the last decade due to greater energy costs and the need to reduce emissions. Ensuring the dependability and capacity of railway infrastructure requires efficient and effective maintenance which, in turn, requires good understanding of various physical behaviours, e.g. deterioration and environmental effects. This paper studies the effect of cold climate on ra...
Passenger flow safety detection in high-speed railway transport hub is considered in this paper. For accurately detecting the passenger flow safety, an improved watershed algorithm and a recognition algorithm are respectively proposed in sensor-based detection process. Computational experiments on sensor data from a specific Chinese high-speed railway transport hub show that the proposed algori...
By taking the super-long railway tunnel as the object of research, based on setting problems of emergency stations adopted by super-long railway tunnels, from the viewpoint of people's safe evacuation, several aspects were studied, such as the mode of evacuation and rescue by adopting emergency station, the number and interval of the cross passage, and the people's safe evacuation time under di...
