IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Total Cost of Ownership of Electric Vehicles: A Synthesis of Critical Factors
The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.This study uses a systematic review to evaluate the total cost of ownership (TCO) as a tool for assessing electric vehicle (EV) feasibility compared to internal combustion engine vehicles. Findings highlight that while EVs have higher upfront costs, supportive policies and lower operating expenses can enhance their competitiveness.

Research on Machine Vision–Based Intelligent Tracking System for Maintenance Personnel
Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.Upon returning to the depot, rail transit vehicles require necessary maintenance. The working condition of train maintenance personnel directly impacts the safety of both staff and equipment. Therefore, effective monitoring and control of activities within train roof access platforms are essential.

Sufficient conditions for polynomial asymptotic behaviour of the stochastic pantograph equation
Electronic Journal of Qualitative Theory of Differential Equations, 2016 This paper studies the asymptotic growth and decay properties of solutions of the stochastic pantograph equation with multiplicative noise. We give sufficient conditions on the parameters for solutions to grow at a polynomial rate in $p$-th mean and in ...

Risk Mapping for Daily High‐Speed Railway Disturbances Based on Operation Loss
Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.Confronted with the disturbances arising from various risk events, it is crucial to accurately measure the severity of risks in the dispatching section for efficient train operation and transportation management of a high‐speed railway (HSR). This paper proposes a risk mapping method for daily HSR disturbances based on a self‐formulated operation loss ...
