Public transport has undergone major changes in recent years. In particular, they relate to the issue of environmental impact. Due to the significant emission of pollutants from the economy, in particular from the transport segment, member states of the European Union have taken measures to limit its scope. Only low-emission and zero-emission vehicles are to be used in transport, and mainly those that are powered by electricity in public transport. The development of battery technologies has led to a revolution in the range and operational capabilities of electric buses in the last decade. They have become a seemingly easy alternative to traditional electric vehicles in public transport—trams and trolleybuses. This article presents the possibilities and limitations of the development of public transport in Poland based on electric buses. An attempt was made to review the literature and compare the possibility of the functioning of buses, trams and trolleybuses in the Polish socio-economic, environmental and technological conditions. The article was based on a literature query, an analysis of unpublished materials, and a qualitative analysis of national programs endorsing the idea of electromobility as well as an online survey on the perception of electric public transport. The main goal of the article was to identify and evaluate the possibilities of developing public transport in Poland with the use of electric buses. The main results of the work include the demonstration that the optics of the national and regional authorities in Poland are focused mainly on electric buses without a thorough analysis of the legitimacy of their operation, especially in small towns. The incentive in the form of subsidizing the purchase of an electric bus is sufficient for them, and the future effects of using electric buses are not investigated.

The aim of the article is to present transport accessibility in rural areas in Poland, with a particular emphasis on the problem of transport exclusion. The following research methods were used in the study: literature review, statistical data analysis and GIS analysis. The article presents a transportation picture of rural areas and identifies the main problem issues related to the insufficient accessibility of public transport. The conducted analyses show a significant alienation of the study area which results from underdeveloped public transport and road infrastructure, including pedestrian and bicycle routes. Measures taken by local authorities in this regard show awareness of the problems of the local community, but those authorities do not take sufficient action. The transport exclusion of inhabitants of the analyzed area can be reduced by developing pedestrian and bicycle infrastructure connecting villages with the existing railway network, characterized by a high frequency of trains.

Development of railway transport systems is perceived as one of the most effective ways of shaping sustainable urban transportation. However, railway transportation systems can only compete with individual means of transportation when having properly developed infrastructure, especially in terms of the train stops accessibility. The main objective of this article is to discuss mutual relations between operation of a newly built railway line and spatial changes taking place in its closest vicinity which determine the accessibility to it. The research methods included the GIS tools, direct measurements of passenger exchange, and public opinion poll among the passengers taking the new line. The research area was the city of Gdańsk, one of the largest cities in Poland, where transportation problems are cumulating as a result of the urban sprawl. The new railway was opened in order to mitigate these problems. The research results have proved this strategy was only partially successful as the course of the line and location of the stops do not provide a large number of potential passengers. That is why it was necessary to connect the line to the already existing urban transportation system, yet this solution has not resolved the problem completely. However, the urban development plan assumes introduction of large housing projects in the areas surrounding the existing train stops what will allow using the new line more efficiently in the future.

Allotment gardens are quite common in many European countries. In particular, they are an important part of the urban space in Central and Eastern Europe. They served to improve the inhabitants’ physical and mental well-being during the communist period and relieved the family budget thanks to their own crops. The article analyzes the functioning of allotment gardens in Poland based on the example of the Tri-City, with particular emphasis on allotment gardens in a prestigious, attractive location. Several research questions were asked regarding the change of the traditional function related to growing fruit and vegetables towards the modern function related to recreation and relaxation. A thesis was put forward that the attractive, seaside location of one of the allotment gardens on the border of Gdańsk and Sopot favors the dynamics of the changes in the function. New garden houses often resemble residential apartments in terms of comfort and function and are used for commercial rent during the summer, even though this is prohibited. In the study, the methods of a field query as well as a questionnaire survey and an in-depth interview were applied to check the state of the allotment holders’ knowledge on the applicable regulations regarding the functions of allotment gardens and their development, the size of garden houses and the rules of staying in the gardens, in particular living there. The questionnaire research and in-depth interviews were conducted at the beginning of 2020. The questionnaire research was conducted in February and March, and the in-depth interviews in May. The most pressing issues concerned the changing functions of allotment gardens and the perception of these changes by allotment owners who have gardens in a traditional form of cultivation. This study also allowed looking at possible neighborhood conflicts that may arise from a change in the function, in particular from the construction of houses with residential facilities, which encourages permanent residence in them, and sometimes subletting to tourists due to their attractive coastal location. The study helped to deepen the knowledge on the functioning of allotment gardens and transforming their functions into residential ones during the summer season. The obtained results show that nearly 60% of the surveyed respondents believe that seasonal occupation of allotment gardens should be allowed if their owners wish to do so. Most of the respondents encountered the problem of abnormal buildings and believe that the regulations in this respect should be followed. At the same time, they do not think that it is causing any problems for them. Conducting in-depth interviews, the information was obtained that the change of functions does not affect the existing, traditional users, and they mostly accept the changes taking place.

The present study attempts to examine the research gap in terms of comparing the environmental impact of trolleybuses and diesel buses in the conditions of a country with an unfavourable energy mix. The analysed example concerns the trolleybus transport system in Gdynia, in northern Poland, which also partially serves the neighbouring city of Sopot. In the last few years, two bus lines have been electrified with trolleybuses in the In-Motion-Charging technology, which enables operation on sections without an overhead network. Using the actual operational data, a comparative analysis of the emissivity of diesel buses and trolleybuses used on the same lines in an identical operating regime was conducted. Moreover, an attempt was made to estimate the damage costs of the emission of air pollutants for the above-mentioned means of transport. Research has shown that trolleybuses significantly help to reduce emissions of nitrogen oxides, non-methane volatile organic compounds and particulate matter, while increasing sulphur dioxide emissions on the served lines. They also generate lower specific emissions of carbon dioxide compared to diesel buses. However, taking into account the differences in the number of seats in these vehicles, the length of routes resulting from a need to provide access to the necessary infrastructure and the total amount of kilometres covered on a given route, they may cause higher emissions per year and per the product life cycle than diesel buses. This is related to the unfavourable structure of energy production in Poland, which is dominated by coal sources. The research results clearly show that the use of trolleybuses in public transport contributes to a reduction of the damage costs of the emission of pollutants that amount to approximately EUR (€) 30,000–60,000 per year for the analysed lines.
