“…This study provides some initial insights into the transformation of public transport systems with the use of new technologies in trolleybuses and corresponds to the previous research results in e.g., ELIPTIC project [89], also for Gdynia [90]. It is a good benchmark and reference paper for similar ones, as the electromobility in urban public transport is developing very fast, becoming a promising pro-ecological way to make cities more sustainable.…”

Transport in cities is one of the most important sources of emissions. Electromobility is an essential element in the catalogue of activities of local authorities aimed at combating climate change. Over the years trolleybus transport has been characterised by both phases of development and regression and is still an essential component of zero-emission urban transport in about 300 cities worldwide. The development of electricity storage technology, especially in the form of a battery, has opened up new prospects for this mode of transport. A trolleybus equipped with a battery (in-motion charging technology) gains unique characteristics for operation independent of the catenary. This study presents the approach for assessing the development of in-motion charging for trolleybuses in all Polish cities operating this means of transport. A set of KPIs has therefore, been set and analysed. The analysis covers a comparison between 2014 and 2019, aimed at showing the development of technological innovations in this field. The results clearly show that in-motion charging technology leads to the development of trolleybus transport, although this development has mainly a qualitative dimension. A key factor determining the development of trolleybus transport using in-motion charging technology is progress in the development of traction batteries.

“…For instance, taxi drivers may feel tired while driving their taxis instead of feeling tired suddenly at the arrival position. Suppose that there is a subject moving from spacetime (t 1 , s 1 ) to spacetime t n , s q and that the subject's value of the specific factor c k is continuous; then, the individual value of the subject during the time period t 1 ∼ t n can be calculated by Formula (24):…”

“…(iii) PT technologies. Bartlomiejczyk et al (2018) [24] introduced smart grid technologies based on the practices in Gdynia and indicated that these technologies could save electric energy for PT systems. Thomä et al (2019) [25] proposed a distributed multi-input-multi-output radar service based on 5G technology to support PT safety.…”

The transportation utility values calculated by traditional utility methods are not comprehensive. Some objects and factors are ignored in traditional utility methods, and this narrow perspective is their primary drawback. In intelligent transportation systems, it is necessary to calculate transportation utility for promoting public traffic planning and management. To build a sustainable intelligent transportation system, modified utility methods are essential to analyze transportation utility in a comprehensive way with innovative technologies and efficient communication systems. To solve the disadvantages of traditional utility methods, it is necessary to establish a new method to build sustainable public transport in the future. In this study, the Multiple Utility Method and Transportation Utility Method are proposed for public transport planning and management from multiple perspectives. A sample is presented to provide a better description, and 69,174 GPS-equipped taxi data in Haikou are adopted for the application of the Transportation Utility Method. The results show that the transportation utility values calculated by the Transportation Utility Method are more comprehensive than the transportation utility calculated by traditional utility methods. This indicates that it is necessary to calculate transportation utility from multiple perspectives based on the Transportation Utility Method. Future directions could include improving the methods, considering more factors, expanding the data used, and extrapolating this research to other cities around the world with similar urban metrics and urban form.

“…The main thing in the formation of intelligent technologies based on SMART Grid is the organization of all-mode computer monitoring of the entire complex of parameters of the power system as the basis for full-scale information support. The use of modern technologies of distributed vector measurements WAMS (Wide Area Measurement System) in which, thanks to the use of functionally oriented microprocessor devices PMU (Phasor Measurement Unit) and the widespread use of GPS satellite navigation systems, have opened up enormous possibilities for carrying out, with high accuracy, synchronous measurements of mode parameters in various points and segments of the distributed power system topology [5,6].…”

The analysis of the problem of innovative transformation of power supply networks of railways made it possible to scientifically substantiate the direction of research related to an optimal strategy for computer monitoring and intellectualization of the processes of power supply of traction substations of railways. Conceptual approaches to the formation of a new model of intellectualization of power supply networks have been developed. Differential models of high organization of synchronous vector measurements are proposed, allowing to determine the comprehensive information content of the primary data. Based on the concept of smart energy, a set of differential models and methods of harmonic and correlation analysis of anomalous and transient processes occurring in power systems has been developed. The REGINA computer system has been designed and manufactured to carry out, in real-time, intelligent monitoring, diagnostics, identification of accidents, optimization of power consumption and expanding the range of market services in managing railway power supply networks. The REGINA system complies with the requirements of ISO 9001: 2015 and the German certification body DOS. Many actual results obtained during the operation of the REGINA on the railways are presented.
