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.\u0000\u0000","PeriodicalId":150174,"journal":{"name":"WUT Journal of Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128245993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.\u0000\u0000","PeriodicalId":150174,"journal":{"name":"WUT Journal of Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115158795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.\u0000\u0000","PeriodicalId":150174,"journal":{"name":"WUT Journal of Transportation Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114126368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
