Analysis of the causes of changes in the spatial structure of traffic accident risk in Tyumen

Abstract

The study examines the factors and causes of changes in the structural characteristics of road accidents on selected major streets of Tyumen from 2015 to 2022. The authors compared road accident data collected in 2015 and in 2022 for three main thoroughfare of the city: Respubliki street, 50 Let VLKSM – Zapolnaya – Chernyshevskogo street, Fedyuninskogo – Bypass Tyumen road – Zakaluzhskaya street. Structural characteristics of accident risks have been identified. The study found that the structure of accident risks for streets located in the city center, middle, and peripheral areas has undergone a significant change over the past 8 years. 1. On the central arterial Respubliki street, a decrease in the annual number of accidents by 19.1 % and a decrease in the annual number of injured in accidents by 20.0 % was observed. 2. On the section of 50 Let VLKSM – Zapolnaya – Chernyshevskogo – Polevaya street, there was an increase in the annual number of accidents by 34.5 % and an increase in the annual number of injured in accidents by 23.4 %. 3. On the section of Fedyuninskogo – Bypass Tyumen Road – Zakaluzhskaya Street, a 2-3-fold increase in road accident indicators was recorded: the annual number of accidents increased by 217.6 %, the annual number of injured in accidents by 136.7 %. In the city center, with an overall reduction in accident risks, the quantitative and qualitative ratios between accidents at intersections and on road segments have changed. The results of this study can serve as a basis for developing practical solutions to improve road safety.
