Abstract
Abstract. The transport infrastructure of Russia is exposed to
multiple impacts of various natural hazards and adverse weather phenomena
such as heavy rains and snowfalls, river floods, earthquakes, volcanic
eruptions, landslides, debris flows, snow avalanches, rockfalls, and ice
phenomena. The paper considers impacts of hazardous natural
processes and phenomena on transport within the area of Russia. Using the
information of the author's database, contributions of natural factors to
road, railway, air, and water transport accidents and failures are assessed.
The total risk of transport accidents and traffic disruptions triggered by
adverse and hazardous natural impacts, as well as the risk of road and
railway accidents and disruptions as the most popular modes of transport, is
assessed at the level of Russian federal regions. The concept of an emergency
situation is used to measure risk. In the risk analysis, 838 emergency
situations of various scales and severity caused by natural hazard impacts on
the transport infrastructure from 1992 to 2018 are considered. The average
annual number of emergencies is taken as an indicator of risk. Regional
differences in the risk of transport accidents and disruptions due to
natural events are analyzed. Regions most at risk are identified.
