Autonomous Vehicles (AVs) are expected to introduce numerous benefits for future mobility. These potential benefits and many others vary substantially by the market share of AVs. Therefore, this research empirically estimates, using the Gompertz function, the projected growth rates of passenger vehicles in Hungary using historical patterns of human-driven vehicle ownership data based on projected per capita GDP. This study’s contribution to the literature is through a mathematical approach that predicts passenger cars market penetration rate, in which the assumptions and the used parameters of the model can be easily modified based on different case studies, or they can be updated due to the advancement in technology and progress in knowledge of the studied market.

The aim of the study was to determine the size of agritouristic accommodation base as well as its utilization in agritouristic farms located in communities with lands belonging to Białowieża National Park and Biebrza National Park. The study was conducted in 2010 and 2011 in 52 agritouristic farms (27 farms – Białowieża National Park, 25 farms – Biebrza National Park). The source data were collected via direct interview technique. The questionnaire form sent to the farms owners was used as the research tool. The data obtained in the study allow us to conclude that the accommodation base utilization indicator in analyzed farms was highly differentiated and was in communities of Białowieża National Park in the range between 1,64%-27,40%, and in communities of Biebrza National Park between - 0,68%-40,55%. The average value of this indicator in both analyzed regions was similar and amounted to 8,1% in Białowieża National Park, 8,9% in Biebrza National Park. The real participation of accommodation places in analyzed market – „market penetration” – in more than a half of farms was negative. The percentage of farms with negative value of this indicator was the same in both analyzed regions and amounted to 56%.

The paper covers development and importance of mobile (cellular) telecommunication services, which developed during last about 20 years and are currently the most important and profitable telecommunication sector. The development of mobile telecommunications becomes essential factor of economic growth in many countries, especially in developing countries. Currently due to the scientific and technological progress as well as the implementation a new standard known as LTE system, cellular telecommunication becomes the basic element of the modern broadband telecommunication infrastructure and internet services. Growing importance of the mobile systems is also connected with great popularity of new mobile terminals – smartphones and tablets. These terminals together with the technology known as cloud computing changed also the ICT market. The paper relates to the situation in many countries, but mainly to Poland.

Zastąpienie samochodów osobowych z silnikami spalinowymi (OSS), samochodami z silnikiem elektrycznym (OSE) pozwala, według wielu ocen, zredukować zapotrzebowanie na energonośne kopaliny i emisję powstających przy ich spalaniu szkodliwych gazów. W związku z tym obserwuje się w ostatnich latach wzmożony wysiłek producentów samochodów nad konstrukcją osobowych samochodów elektrycznych, które zadowalałaby ich użytkowników. Może to także oznaczać pojawianie się SOE w osiedlach mieszkaniowych i konieczność ładowania ich akumulatorów z sieci rozdzielczej.

Replacing of gasoline engine driven cars with electric vehicles enables, according to numerous opinions, to reduce the demand for carbon-rich fossils and to limit harmful gases emitted at their burning. A substantial effort of car manufacturers has been observed in the last years aimed at the development of electric vehicles that might satisfy their users. It means that such vehicles could appear in residential neighbourhoods where their batteries would be charged from the residential distribution grid. Grid operators could ask questions, therefore, on how this charging would affect the grid performance; how they should be prepared for that and when this could happen.
