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...
