Analysis of injury indicators in 2020 and 2021 in Irkutsk public highways

Abstract

The article compares the main indicators of injuries for 2020-2021 on the Irkutsk highways according to the statistics of the State traffic inspectorate. The analysis showed the absence of a clear decrease in the relative indicators of road injuries in 2021: as compared to 2020, the number of accidents increased (9 %), the number of injured (14,5 %) increased, and the accident severity coefficient increased by 6 times. The seasonal nature of the dynamics of traffic accidents was revealed. For example, an increase in the number of road accidents in 2021 as compared to 2020 was observed in April, October and December, an increase in the number of fatal road accidents was noted in January, February, March, April and July 2021. Therefore, for the correctness of the analysis, the calculated average monthly data of the State traffic inspectorate were used. The distribution of incidents by time of day has not changed. The greatest number of road accidents occurs from 17:00 to 20:00, which can be explained by an increase in vehicle traffic after the working day and the onset of twilight. The tightening of administrative penalties for non-compliance with traffic rules by drivers ensured a slight decrease in accidents in 2021, namely, the total number of drunk drivers in Irkutsk driving all types of vehicles in 2021 decreased by 1.68%, still remaining quite large (11,75 %). It should be noted that in 90 % of cases, both in 2020 and 2021 the drivers of a personal car in a drunken state were the culprit of the accidents. Drivers between the ages of 30 and 40 are the most likely to commit traffic violations. Significant causes and factors of transport accidents are shown. In 2021, the vast majority of road traffic accidents (40,2 %) occur for 2 reasons: collisions 41,62 % (39,49 % dead and 48,28% injured); collision of a vehicle with a pedestrian 29,35 % of accidents (26,43 %  dead and 22,17 %  injured). The same main reasons for the traffic accidents have been noted in 2020. Cases of collision with a standing car became more frequent by 1,26 times. In 60% of collisions with pedestrians, car drivers are guilty, in 40% - the pedestrians. Of these, 36% of collisions are made at night, 35 % of such incidents occur at pedestrian crossings. There has been a significant increase in traffic accidents with, and the number of affected adolescents, and in 54.8 % of such cases, child passengers suffered. The only decrease was in the number of traffic accidents with violation of the rules for transporting children and with child pedestrians.
