STABILITY OF INTRA-ANNUAL DYNAMIC TREND OF MOTOR-VEHICLE ACCIDENT RATE IN CITY
The questions of statistically steady repetition of characteristics for road accident formation through time are considered in this paper. The research purpose is a test of hypothesis that road accidents are formed through time not in a random way but they are distributed according to the certain regularities which are constantly repeated. Discussions on long-term stability of road accident rate in a city are based on research of distribution repetition of an unevenness indicator of the accident rate characteristic - unevenness coefficient of road accident according to the months K unev. RTA month. The means of such research was definition of Wilcoxon T-criterio, on the basis of which the conclusion about hypothesis confirmation of the absence of statistical distinction among the road accident distributions according to the months for 2012 and 2005 is defined.On the basis of comparative research results of road accident statistics the basic conclusion about existence of stability phenomenon of intra-annual dynamics for road accident rate is formulated. The corrections of all type resources made by traffic safety organizers taking into account the actual intra-annual trend for accident rate are considered to be the practical result of the research about trend stability of intra- annual dynamics for road accident rate in a city.
