At the Rest and Service Areas (R&SA) both in Poland as in European Union are observed in-creasing problems with availability of parking slots for trucks and semi-trailers. Insufficient number of parking slots is caused mainly by daily truck traffic and parking fluctuations. Drivers of such vehicles are obliged by Regulation WE 561/2006 [6] to take regular stops. At the same time Regulation 885/2013 [5] of the UE Commission imposes on member states a duty to ensure the adequate number of spots on safe and secured parking’s. Article presents the results of the research on parking occupancy that were performed on chosen section of A4 highway in Poland. Additionally authors propose the method to ensure additional parking slots for trucks and semi-trailers using only traffic management means.

Exploitation of railway vehicles, especially in the case of goods transport, on lines with small-radius curves, results in accelerated wear of wheel profiles and rails in curves. This results in increased operating costs and can lead to derailments on such the lines. One of the ways to reduce these negative effects and to improve the wheel-rail interaction in sharp curves is to cover the surface of the wheel flange with coatings of materials with self-lubricating properties. Covering the wheel flange surface with a suitable coating reduces friction coefficient in case of flange-rail head interaction. However, there is a question about the effect of the self-lubricating layer on the safety of the vehicle. The paper presents the results of simulation analysis of dynamic behavior of a two-axial coal wagon with a modeled self-lubricating coating and its effect on wheel wear.

Interactions between aviation and the environment are rather complex, and consist of both wildlife strike hazards and negative impacts on protected species and habitats. Rapid growth of air traffic causes systematic growth in wildlife strike numbers. Climate changes affect geographical distributions of some big bird species that are hazardous to aviation. One can expect a concomitant growth of wildlife strike risk caused by species such as geese, gulls and corvids in next 30-50 years. Therefore significance of the complex and interdisciplinary proactive approach to manage the risk, will grow. Its success, measured by increased aviation safety, will depend on a fruitful co-operation among aviation and non-aviation stakeholders and experts. This co-operation includes aviation authorities, scientists as ornithologists, ecologists, land owners, and local governments. Additionally, a civil-military as well as international co-operation is extremely important, aiding in radar data analysis or legislation, for example.

One of the methods used to provide an immediate delivery service is to engage the final recipient in a part of the distribution process, which significantly affects the supply chain. Currently, the customer decides where and when he will want to pick up the package with the goods. In order to above, the concept of "last mile" facilities appeared. The article describes the concept of "last mile", including "last mile" facilities. These facilities include elements of the distribution system enabling direct collection or parcel delivery by the customer. The article presents the problems of locating objects of this type in the supply chain and their location in space. The limitations and criteria taken into account during the location assessment are presented. A multicriteria procedure for the evaluation of location variants of "last mile" facilities has been proposed.

This paper contains the mathematical model of an inadvertent stall as the incipient phase of a spin. Some further simplifications were included. Representation of a rigid plane was modeled as the three-dimensional movement of center of gravity. The equations of motion were presented, as well as the basic equations for the LLT method. The aerodynamic stall as the specific flight phase and the Loss of Control in Flight cause of aircraft accident sets the global safety concern that needs further actions. The created mathematical model shall be used for creating simulation algorithms for an inadvertent stall.

The article presents the results of the technical state of shock absorbers on the stand with harmonic Eusam type kinematic forcing applied at vehicle inspection stations. As operating parameter, the pressure in the tires was assumed (assumed a reduced value in relation to the recommended nominal value) and the impact of this parameter on the values obtained during testing on the test bench was determined. The measurements were carried out several times. The results are summarized in tabular form and in the form of a graph and based on them final conclusions were formulated.

Currently, the law on the use of unmanned aircraft is passed individually in each EU member state. The European Aviation Safety Agency (EASA) intends to create uniform community rules, that will regulate UAV (Unmanned Aerial Vehicle) flights in each EU country. The main assumptions of the strategics proposed in the draft document prepared by EASA "Introduction of regulatory framework for the use of drones" is the division of flights into categories: open, special and certified, as well as the implementation of the U-Space concept, a platform for the management of unmanned aerial traffic. The article presents provisions regarding the use of unmanned aircraft in Polish airspace in accordance with current standards and regulations. The conditions for obtaining operator qualification certificates (UAVO) are also described, as well as the permissions for the operators, both basic and additional, and the process of obtaining them. These permissions are issued in the form of a qualification certificate after completing the theoretical and practical training and passing the state examination in presence of the examination board in the scope required for obtaining these qualifications. In addition, the authors presented the conditions for performing UAV flights in the airspace structures of FIR Warsaw. The article presents the prospects for unmanned aerial vehicle market development by identifying new legal challenges proposed by EASA, and the outlines of both the draft of the new Regulation as well as the government programme called "Zwirko and Wigura", an initiative resulting from state actions for the development of new technologies, in particular the integrated management systems.

In 2016, the Organisation for Economic Co-operation and Development published a report in which a modeling was conducted (based, among others, on current emissions, population distribution, economic and demographic trends) that allowed for forecasting the economic consequences of air pollution up to 2060. The project’s authors stated that if countries do not take up more action to improve the quality of air than those introduced the number of early deaths due to air pollution can increase until 2060 and amount to 8-9 million people annually. At the same time, they emphasized that if adequate steps are incorporated in terms of cleaner energy sources, public transport or emission limits, among others, there is a high chance that the air quality improves, which in consequence will substantially lower the health effects and costs. One of the currently introduced solutions is the dissemination of plug-in electric vehicles (PEV), i.e. battery electric vehicles (BEV) and plug-in hybrid electric vehicles. This paper presents the current state of the market for such cars, as well as forecasts of its development. Special emphasis was put to the related plans of car manufacturers.
