The article presents the results of correlation analysis of the causes of road accidents in such a modern metropolis as Minsk. Has been identified the most frequent causes of road accidents, including pedestrian collisions caused by drivers, collisions at intersections, incidents at controlled and unregulated pedestrian crossings, as well as on the roadway. The dependence of transport incidents on the time of day, day of the week and month of the year was investigated. Shows the periods when road traffic incidents occur from 3.00 to 6.00 h, from 15.00 to 18.00 and from 21.00 to 24.00 on Monday, Friday and Sunday in January, March, June, September, October and November. Methods of correlation and multiple regression analysis can be the basis of preventive traffic safety management in a modern metropolis.

Statistical Criteria

Проведен системный анализ влияния мультипликативных помех на условия разрешения сигналов на основе статистического критерия с помощью математического моделирования. Показано, что интервалы разрешения по времени запаздывания и частотному сдвигу при известных статистических характеристиках сигналов, аддитивных и мультипликативных помех однозначно определяются вероятностями правильного и ложного разрешения. A system analysis of the influence of multiplicative interference on the signal resolution conditions based on a statistical criterion using mathematical modeling is performed. It is shown that the resolution intervals for delay time and frequency shift with known statistical characteristics of signals, additive and multiplicative interference are uniquely determined by the probabilities of correct and false resolution.
