AbstractThe capital of Romania is the main railway hub of the country. As such, the railway network around the capital is quite extensive, with main cities around it being directly connected by rail. Despite this, there are no regular train services for commuters, similar to other large European cities. This paper aims to analyze the current state of railway passenger transport in the region surrounding Bucharest, to highlight the weaknesses of the network and to present a guideline for the implementation of an efficient commuter service. 100 stations in and around the city were evaluated with regard to their degree of accessibility (DoA), defined as the location of the station relative to the nearest settlement. Train frequency, travel times and journey costs were determined for each line originating in Bucharest. These variables were compared to their road equivalents to highlight the differences between these two modes of transport. Low train frequency and the remoteness of many stations were determined to be the main obstacles in establishing an appropriate commuter service. Reworking future timetables to prioritize commuter trains is proposed as a short-term solution, while line improvements and better integration with existing public transport are set as priorities.

High Quality Service

With the increase of the railway operating mileage, the railway network is becoming more and more complicated. We expect to build more railway lines to offer the possibility to offer more high quality service for the passengers, while the investment is often limited. Therefore, it is very important to decide the pairs of cities to add new railway lines under the condition of limited construction investment in order to optimize the railway line network to maximize the reliability of the railway network to deal with the railway passenger transport task under emergency conditions. In this paper, we firstly define the reliability of the railway networks based on probability theory by analyzing three minor cases. Then we construct a reliability optimization model for the railway network to solve the problem, expecting to enhance the railway network with the limited investment. The goal is to make an optimal decision when choosing where to add new railway lines to maximize the reliability of the whole railway network, taking the construction investment as the main constraint, which is turned to the building mileage limit. A computing case is presented based on the railway network of Shandong Province, China. The computing results prove the effectiveness of the model and the efficiency of the algorithm. The approach presented in this paper can provide a reference for the railway investors and builders to make an optimal decision.

The sustainability of services in undertakings which operate in railway passenger transport is closely connected with efforts to provide high-quality and time-acceptable services to the customer, to achieve lean processes, to standardise work processes, to eliminate wastage and to avoid those activities which do not add any value. Considering its ecological nature and big volume of passenger transport, railway passenger transport represents an irreplaceable sustainable system for the future. These facts and the entry of new railway carriers into this system highlight the importance of managing risks in a progressive way. This article focuses on the options of risk management when versatile and flexible tools, such as Lean tools, are set correctly. The aim of this article is to introduce a proposal for the application and a specific application of Lean philosophy in risk management which impacts train delays in railway passenger transport. From the point of view of quantitative data analysis, multiple mathematical-statistical tests have been used to assess data (e.g., Anderson–Darling test, Kolmogorov–Smirnov test, Jarque–Bera test, two-tailed test, Grubbs’s test and Thompson Tau test). Also, descriptive statistics and ANOVA test (Analysis of Variance) have been applied in the process of evaluating the monitored attributes. In order to assess the data dependency, Chi-Square Test and a correlation analysis have been applied. The research outcomes focus on highlighting the need for a systematic approach for train delays and to avoid delays through risk management. The case study applies selected Lean methods to monitor train delays in selected stations within the main railway corridor of the Slovak Republic for the period from 2015 to 2018. In 2019, the results were processed and created a basis for proposing a unique software tool like an aid for risk management in the case of train delays using Lean philosophy. The flexible software includes the participation of employees, and at the same time, it respects the needs of customers. The research results provide grounds for further study of risks in a challenging environment of railway undertakings, with different types of trains, railway stations as well as entire railway networks. The processed results of the article represent valuable material for railway undertakings not only in Slovakia but also for railway organisations in V4 countries.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

This study presents a fuzzy Bayesian network (FBN) method to analyze the influence on the safety risk of railway passenger transport applying different risk control strategies. Based on the fuzzy probability of the basic event determined by the expert group decision method, the proposed FBN method can reasonably predict the probability of railway passenger safety risk. It is also proven that control the risk in the safety management of railway passenger transport will be the most effective way to reduce the risk probability of the railway passenger transport safety.

This chapter presents a case-study of tourism gentrification in a fishing town in Algarve, South Portugal. Olhão is a former industrial city that saw much of its fishing industry disappear since the 1980s. Over the last few years, hundreds of foreigners have moved into its historic centre. This rapid influx of citizens to derelict neighbours mostly comprised of old retirees and few active fishermen prompted a gentrification process. Olhão now faces the threat of mass displacements of its older and most vulnerable citizens, a fact that is worrying the foreigners that criticize the touristification of the city, with rents at historical highs and landlords forcing out the Portuguese residents in order to promote short-term rentals to tourists. The chapter presents the results obtained from an extensive mixed-methods research, ending with some notes about the future of the city and the implications that can be taken from this case.

Further Development

The article presents research materials and analysis of factors affecting the creation of new nodes of public spaces, as starting points for the development of Kotlin Island and the city of Kronstadt. Their current state and problems, resources and opportunities are described. Currently, there is a process of rethinking the value of the coastal territories of Kronstadt, the potential of which is not realized. One of the possible ways to solve this problem is to increase the use of coastal territories by creating tourism and public-business infrastructure along the coastline. Kronstadt has a number of unique characteristics, the use of which can transfer it from degrading to developing. This is possible by creating a polycentric model in the city - new growth points, as well as rethinking the value of abandoned and coastal territories. This approach will not only increase funding, attract more people, provide a sufficient number of jobs, but also subsequently create conditions for the further development of the city as an independent unit - the center of the St. Petersburg metropolitan area.
