Оценка эффекта от некапиталоёмких мероприятий по сокращению аварийности в местах концентрации ДТП в крупнейших российских городах
The article is devoted to the analysis of the of non-capital-intensive measures contribution within the framework of the national project “Safe Quality Roads” to the reduction the number of road accident concentration spots in Russian cities with a population of over 1 million people. Based on the spatial analysis, the seasonal nature of changes in the number of accidents was determined. The road accident concentration spots in the cities were identified with QGIS Software Clustering Tools, and their combination with non-capital-intensive measures was established. Using the statistical analysis, Pearson's chi-squared test, classification trees, the non-parametric Mann-Whitney test, the fact of saving/eliminating road accident concentration spots after or without road measures was evaluated. The study made it possible to conclude that measures of The National Program “Safe Quality Roads” do not always lead to the elimination of road accident concentration spots. The effect of the measures in the road accident concentration spots located near intersections and public transport stops is much lower than in other areas.
