“…The influence of operational load on railway lines is manifested by permanent changes in the geometric parameters and material characteristics of the track length [14][15][16]. Changes in the structure of the superstructure may result in reduced safety, smoothness and quality of the railway transport on railway lines.…”

Ensuring the safety of railway transport operation requires constant monitoring of the technical condition of individual elements of railway infrastructure. The necessary activities that contribute to maintaining good operational condition of the railway transport line also include the diagnostics of track length. Diagnostics of railway tracks is most often performed by means of regular visual inspection (in the conditions of the infrastructure manager – ŽSR). The objective of the article is to provide information on the application of a new approach to diagnostics of the technical condition of railway infrastructure. The new approach to defect identification on railway infrastructure uses non-invasive diagnostic methods based on the latest knowledge in the field of information and communication technologies. These facts resulted in investigating the possibilities of automatic detection of the technical condition of the track length using neural networks. The article is part of the following scientific research task: ‘Research into new knowledge and observational experience of a new generation of diagnostic systems in industrial production and transport industry – research into the physical nature of an automated track length video inspection system’, supported by the Ministry of Education, Science, Research and Sport of the Slovak Republic.

“…Another possible solution is the integration of passenger and freight transport for first-last mile operations [2,15] and use of railway transport [16]. A specially designed simulation tool serves for the application of different open fleets (from freight vehicles to cargo bicycles) in urban logistics [17].…”

The Growth of E-Commerce Due to COVID-19 and the Need for Urban Logistics Centers Using Electric Vehicles: Bratislava Case Study

et al. 2021

Before the COVID-19 pandemic there had already been an increase in individual shipment transportation including inner-city areas. During the pandemic and implementation of adopted preventive measures, it has increased by more than 100% in some cities. This presents an unsustainable development, particularly in terms of urban environment. The above-mentioned development has accelerated the research related to optimal allocation of logistics centres considering the last-mile distribution. Unfortunately, the theoretical mathematical model that finds an optimal urban logistics centre location based on the matrix of distance, number, and weight of shipments is not applicable in most cities. Therefore, the following research methodology was chosen in accordance with the approved territorial plan. The authors considered those locations in Bratislava—the capital of Slovak Republic—which are designated, or suitable for building up of an urban logistics centre. These localities were afterwards evaluated in a real-world case study employing methods of mathematical programming (linear programming), the nearest neighbour method, and the Clarke-Wright method. The presented methodology can be applied not only when deciding on the appropriate location of the city logistics centre, but also at optimizing the vehicle routing problem. Taking into account the urban logistics sustainability and the e-commerce growth, it was analysed whether the suggested location of urban logistics centre is feasible to provision examined facilities using electric vehicles. The range of considered electric vehicles of N2 category present in the market tends to be at the limits of distribution routes length for the given case study. Therefore, the article also deals with the fast-charging possibilities of vehicles during handling operations and the use of hybrid freight vehicles in city logistics.

“…The problem is bigger with development of the e-commerce and increasing urbanization. Several improvements are described in literature [9][10]. Authors in [11] describe that the last mile of the supply chain is considered as one of the most, or even "the" most, expensive, inefficient and polluting part of the supply chain.…”

The first and last mile part of the public transport journey are essential for the whole transport system. Its quality affects the overall experience of the passenger in public transport. It is not important how attractive are individual transport modes if the rest of the journey is unattractive for the passenger. This paper is about shared mobility and it describes the connection between the first/last mile and the public transport system. Modes of shared mobility can reduce the pressure on the city transport system. It can also bring a better modal split. The authors performed a traffic-sociological survey for processing the respondents' opinions on the use of new modes of the sharing economy. The survey showed that more than eighty per cent of people travel to work daily, but more than half of them do not use public transport.
