Winter slippery conditions on the roads for Khanty-Mansi autonomous okrug - Uugra
The results of evaluating the winter slippery period on a road network in the Khanty-Mansi Autonomous Region-Yugra are presented based on calculated specialized indicators. It is shown that the winter slippery period begins in the first decade of October and lasts until the third decade of April, amounting to 155-190 days over the cold period. The data on the number of days per year with different intervals of negative temperatures allow the calculation of the ratio of requisite anti-icing materials for the cold period. The number of days with possible events of winter slipperiness formation in areas with the highest density of the road network has increased since 2011, while the duration of the period with slick roads remains almost unchanged. This leads to an increase in the number of treatment required to retain the quality and efficiency of work when maintaining public roads to ensure road safety.
