Bangladesh has launched the mass rapid transit (MRT) service for the first time in the transportation sector. The MRT has significantly brought access to instantaneous communication in one of the congested cities, Dhaka. Since the service is a brand-new offering in Bangladesh, there is a complete gap in research in this sector. Therefore, the objective of this study is to evaluate the effects of service quality dimensions on passengers’ satisfaction with MRT in Bangladesh. The researchers used a convenient sampling method and collected primary data from 251 respondents who consumed the MRT service frequently. Using the reliable software Smart PLS 3.0, the data were analyzed. The researchers have examined Cronbach’s alpha, composite reliability, and average variance extracted (AVE) to test the reliability and validity of the collected data. This study finds that the constructs namely tangibility, responsiveness, assurance, hedonic motivation, and price value are significant in determining passengers’ satisfaction with MRT. Price value is more significant followed by hedonic motivation and responsiveness. In contrast, statistics reveal that reliability and empathy are insignificant in nature.

“…The fundamentals of building energy storage systems in traction power supply systems are based on the specifics of the traction load, which is taken into account in various ways based on traction and electrical calculations using various modeling tools, for example, as shown in the example of improving the efficiency of regenerative braking in the subway and using batteries and renewable energy sources [1,2]. A number of researchers are considering the issues of redundant power supply, for example, as shown in [3] for an electric train with an onboard battery and hydrogen cells.…”

The improvement of traction power supply systems of the transport complex is associated with the search for new technical solutions that can improve operational and energy efficiency, reliability and energy security. Electric energy storage systems make it possible to solve these problems. One of the aspects of the application of electrical energy storage systems is the voltage mode at the connection points. The studies of the operating modes of electric energy storage systems on mobile vehicles and stationary objects show the short duration of charge and discharge episodes due to the traction load of electric vehicles. An urgent task is to assess the change in the voltage level of electric energy storage systems in short-term modes when operating in traction power supply systems for various electric energy storage devices. The paper describes a model of the traction power supply system and electric rolling stock containing electric energy storage systems. The change in the degree of charge and voltage depending on their capacity and the time of the applied load is shown. For the conditions of the traction power supply system, the most preferable ones in terms of the minimum voltage level were selected.
