Adverse weather impact on infrastructural aspect of transportation system supply

Over time, the transportation planing process became more sophisticated and comprehensive considering the wider range of indicatores that could affect balance between transportation supply and transportation demand. Considering urbanization and motorized traffic increase, the necessary capacity provision became a particular challenge. Therefore, it became especially important to take into account all the potential impacts that could lead to the capacity reduction. Actualization of climate change phenomenon intensified the research of weather impact in all segments of society development, including transport. Climate changes contributed to the variability of weather conditions characteristics. When it comes to the urban street network, despite the fact that even without specific research can be concluded that adverse weather conditions reduce the transport system efficiency, significant progress in reducing or eliminating consequences of that impact is not made. In this paper, the focus will be on the results of significant studies that analysed adverse weather impact on infrastructural aspect of transportation system supply, i.e. street capacity.
