Electrified transportation and power systems are mutually coupled networks. In this paper, a novel framework is developed for interdependent power and transportation networks. Our approach constitutes solving an iterative least cost vehicle routing process, which utilizes the communication of electrified vehicles (EVs) with competing charging stations to exchange data, such as electricity price...
Hybrid electric propulsion, using batteries for energy storage, is making significant inroads into railway transportation because of its potential notable fuel savings and the related reductions in greenhouse gases emissions hybrid traction over non-electrified lines. Due to inherent complexity hybridized powertrains, combining different power conversions storage capabilities, corresponding ope...
The present article focuses on the efficient deployment of dual locomotives in regional rail freight transport considering quantification traction energy and savings. In first part article, a categorization locomotives, according to their power output electric alternative (and ratio both outputs) is proposed. potential chosen Central European conditions (a sub-network Czech railway network arou...

Railway wireless communication has become an indispensable part to provide the reliability and safety of the railway operation as well as the improved railway services. In addition, advanced mobile communication technologies have triggered new railway customer services. Thanks to many benefits of the 4-generation mobile communication technology, long-term evolution (LTE), this technology is one...
objective: the environmental exposure to magnetic fields (mfs) may interact with biological systems. mfs are generated from various sources such as power lines, electric appliances at homes and offices, electrified transportation systems including urban railway systems and diagnostic devices such as magnetic resonance imaging (mri). there are some scientific evidences that imply the exposure to...
We compare the potential of hybrid, extended-range plug-in hybrid, and battery electric vehicles to reduce lifetime cost and life cycle greenhouse gas emissions under various scenarios and simulated driving conditions. We find that driving conditions affect economic and environmental benefits of electrified vehicles substantially: Under the urban NYC driving cycle, hybrid and plug-in vehicles c...
Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design
The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...
The significant function of GIS technology in promoting the railway development in this information era is now attracting great attention from the Ministry of Railway and the State decision-making institutions of the P.R.China. However, until present, the GIS has not been economised on the Chinese Railway. Discussions have been made on the several critical issues in building up the railway GIS....
