Unhealthy lifestyle choices and passive behaviour are a significant problem for many developed countries. They lead to a decrease in public health in the form of diseases related to contemporary civilization, such as: cardiovascular diseases, type II diabetes and obesity. This increases the costs generated in the healthcare system. The share of costs resulting from combating these diseases increases every year. The choice of a transport mode used when commuting is often perceived as one of the factors leading to more proactive behaviour and thus decreasing the externalities not only connected directly with transport such as pollution, noise, congestion and accidents, but also those connected with public health. The paper shows the results of a study performed in Poland, which was meant to identify and measure the relations between the transport choices and other proactive choices of commuters. A logistic regression model was estimated to identify the occurrence and intensity of these relations. The goal of the article is, therefore, to assess whether the choice of a transport mode used when commuting is connected with other types of proactive behaviour of citizens. In particular, the author wishes to determine if people choosing a car as their mode of transport tend to be generally less active than people choosing public transport or those who commute actively.

Polycentric metropolitan area Trojmiasto in the north of Poland, by the Gdansk Bay is one of the most important urban centres for the Polish economy. The level of development of the collective public transport system is one of crucial factors for the functioning of such a vast urban area. Public services, in the form of local government departments or budget units are responsible for the organisation of transport services within the metropolis. They are coordinated by the metropolitan public transport union, MZKZG. Either municipal or private carriers are responsible for the realisation of transport services. The metropolitan transport market is dominated by public services or private businesses, while the "third sector" subjects have a relatively small participation in the market shaping process, mostly due to their lack of competiveness, connected with the non-profit activity formula. The objective function of those subjects is based on the desire to fulfil the needs of a limited social group, which are not satisfied through the default market mechanism. Hence, the NGOs organise special transport services, which do not fit within the objectives of traditional public services. Therefore, the objective function of the NGOs and the objective function of the subjects which create transport policy are convergent, however the scale of work of NGOs is far smaller, because of the fact that various constraints exists, not all of which are, however, active. The methodology of operational research allows to analyse the problem of the NGO activity in the process of shaping the Trojmiasto metropolitan transport market which is formulated in this way. Operational research on the constraints of NGO activity lead to a conclusion that the furthest constraint is the lack of periodic financing sources. The third sector organisations also point out heavy competition between them and barriers against access to the transport services feasibility studies. Therefore, the adaptation of the role of a transport policy stakeholder seems a necessary predictive value for the non-government organisations.

Purpose – The world is undergoing a dramatic shift in climate conditions. A heated debate is on-going over what measures to take in order to overcome the global-warming-related temperature increase, now more than 2 degrees centrigrade. The article tries to evaluate the contribution of the feed-in tariff (FIT) and the price of components for solar plants to the accumulation of new solar capacities in Germany, with the aim of determining the reasons for a drastic decline in the new capacities, observed since 2012. Methodology – An autoregressive integrated moving average (ARIMA) is used with the new PV Capacities as a dependent variable and component prices and feed-in-tariffs as independent variables. Data from German Federal Network Agency is used. Findings – The statistical analysis shows a significant effect of component prices (in EUR per watt) and the value of the FIT (in EUR) on the New PV Capacities. As Germany has not reached the postulated yearly increase rate of New PV Capacities of 2500 MW since 2014 (EEG, 2017), new approaches are necessary to overcome this situation
