Electrically assisted bicycles are anticipated to become an effective tool to limit not only the use of cars in cities but also their negative impact on health, the environment, and passenger transportation in cities. In this paper, we examine the effects of implementing the first fully electric bike (e-bike) sharing system in the Metropolitan Area of Gdańsk–Gdynia–Sopot in Northern Poland, where no other bike sharing system had been introduced before. The aims of this article were to determine the impact of the new e-bike sharing system on the modal choice of citizens, identify barriers to its usage, and find differences between the usage of the system in the core of the metropolitan area and in the suburbs. We used two primary data sets: the survey data collected using the computer-assisted personal interviewing technique (CAPI technique) and the data automatically acquired from the website that monitored the system activities. We performed the analysis by using nonparametric tests and correspondence analysis. We found no evidence suggesting that e-bike sharing can replace large number of private car trips, but we found it likely to be competitive to carsharing, moped, and taxi services. E-bike sharing competes also with public transportation services, but it is also used as the first/last mile of the transportation supplementing public transport system. The major barrier to using this system in central cities of the metropolitan area was the lack of available public bikes, and possession of private bicycles, whereas for residents of the suburbs, the obstacles were the need to transport children, the high price of the bicycle rental/subscription, and the long distance to the docking stations.

As no effective treatment or vaccine have yet been developed, the only way to prevent the spread of SARS-Cov-2 is to introduce social distancing measures. Scientific discussion regarding their actual effectiveness and socio-economic consequences has only just begun. Both declining mobility and changes in mobility patterns are obvious effects of social distancing. The main objective of this article is to present spatial diversity of changes in regional and local mobility in Poland with the use of data gathered and provided by Google LCC. As for the regional dimension, the mobility has declined steadily in most of the analysed areas. The regional changes were more visible only in the case of the following categories of areas: grocery & pharmacy and parks. The initial correlation analysis has shown that distribution of those changes more or less reflects spatial voting patterns. Both historical and cultural factors may explain such results, including ingrained habits, collective attitudes towards politics and group values. In the local context, illustrated by the analysis of changes in travel time from housing areas in Gdańsk, Gdynia and Sopot to the business and science centre in Gdańsk-Oliwa, a noticeable yet spatially diversified decrease in drive time (by private car) has been observed. The most significant reduction in travel time was recorded in peripheral areas accessible by high-speed roads which are normally jammed during peak hours. The mobility constraints have led to highly reduced traffic congestion, and consequently, shortened the travel time.

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.

cytacja:Tarkowski M., 2016, Mobilność miejska jako wyzwanie strategicznego programowania rozwoju lokalnego -przykład Gdańska, Prace Komisji Geografii Komunikacji PTG, 19(4), 7-18. streszczenie: W toku transformacji ustrojowej zjawisko kongestii transportowej w polskich miastach ulegało systematycznemu nasileniu, osiągając poziom znany z większości miast krajów wysoko rozwiniętych. Z uwagi na koszty środowiskowe, społeczne i ekonomiczne problem ten znalazł się w centrum lokalnych debat politycznych, zmuszając władze do zajęcia stanowiska i podejmowania prób jego rozwiązania. Celem niniejszego artykułu jest omówienie przekształceń w zakresie głównych priorytetów i narzędzi polityki transportowej w mieście na przykładzie Gdańska, identyfikacja uwarunkowań tych zmian, a także wskazanie potencjalnych zagrożeń dla osiągnięcia założonych celów. W pracy zastosowano metody kameralne -dokonano analizy głównych dokumentów programowania rozwoju. W dokumencie pt. Gdańsk 2030 Plus Strategia Rozwoju Miasta (2014) sformułowano jednoznaczne wyzwanie wskazujące na potrzebę zwiększenia udziału ruchu pieszego, rowerowego i transportu zbiorowego w strukturze zadań przewozowych. W 2016 r. w Gdańsku, podobnie do większości dużych polskich miast, na transport indywidualny przypadało 41% podróży (Gdańskie Badania Ruchu…, 2016). W stosunku do 2009 r. udział ten wzrósł, mimo znaczącej modernizacji infrastruktury transportu zbiorowego. W celu odwrócenia niekorzystnej tendencji przewidziano wdrożenie szerokiej palety działań. Jednocześnie pozostawiono możliwość wykonania inwestycji, które, w zależności od szczegółowych rozwiązań, mogą wspierać zmianę podziału zadań przewozowych, jak i konserwować istniejące proporcje. Przyczyny powstałej niekonsekwencji wynikają zarówno z przyjętych wcześniej programów rozbudowy infrastruktury transportowej w nowo zabudowanych dzielnicach, jak i niejednorodnych opinii mieszkańców na temat priorytetów rozwoju transportu w mieście. Mocną stroną dokumentów strategicznych jest natomiast dostrzeżenie związków pomiędzy celami rozwoju transportu i mobilności miejskiej a celami innych programów operacyjnych. Stwarza to warunki do poszukiwania synergii pomiędzy działaniami prowadzonymi w różnych obszarach polityki rozwoju miasta. słowa kluczowe: Gdańsk, mobilność miejska, podział zadań przewozowych, strategia rozwoju, transport abstract: In the course of political transformation the phenomenon of traffic congestion in Polish cities systematically grew stronger, reaching level which is known for the for most ones in developed countries. Due to environmental, social and economic costs this problem was moved to the core of local political debates, forcing the authorities to take a stand and attempt to resolve it. The aim of this article is to discuss the transformations on the main priorities and instruments of transport policy in Gdansk, identification of determinants of these changes and potential threats to the achievement of goals.

Marine spatial planning is a relatively new area of cooperation in the Baltic Sea region — a site of long-term joint efforts towards environmental protection and sustainable development. At the beginning of the 21st century, the integrated management of coastal zones and marine spatial planning emerged as a new area of international cooperation. Despite intensive theoretical work on the mentioned concepts, the development of a harmonised spatial planning in the Baltic Sea region is complicated by the complex nature of the problem, a relatively intensive exploitation of marine resources, diverse interests of the stakeholders, and differences in national institutional systems. We describe the key stages of the process, which is regulated by the EU standards on the one hand and affected by the activity of such organisations as VASAB and HELCOM, on the other. In this article, we examine basic documents defining the principles and scope of marine planning and analyse recent research works into spatial development. We conclude that marine spatial planning is a principal tool of the EU’s integrated policy. Many European countries of the Baltic region are seeking cooperation with Russia to preserve the natural and economic environment of the Baltic Sea. Most joint spatial planning projects have been initiated by Finland, Sweden, Germany, and Poland.
