IMPROVING THE METHODOLOGY OF EXPERT SAFETY LEVEL ASSESSMENT OF ROAD TRAFFIC

Abstract

The article is devoted to the improvement of the method of expert safety level assessment of road traffic. A general analysis of road safety assessment methods and techniques was performed. Proposed ways to improve the methodology of expert assessment of the level of road safety based on the use of a combination of statistical and proactive models. The object of research in the article is the process of assessing the level of road traffic safety in a specific area at a certain time. The purpose of the study is to improve the methodology of expert assessment of the level of road safety based on the analysis of foreign and domestic experience. The article provides a general analysis of road safety assessment methods and techniques. It has been established that the indicators of most of the developed methods and techniques for assessing the level of security are based on one of two methodological approaches - the use of statistical and reactive methods and models or proactive and prognostic methods and models. However, it was determined that the analyzed methods and techniques mostly do not establish the influence of external conditions, in particular, variable road factors when assessing the level of road safety. The author's approach is proposed - a method of expert evaluation of road traffic safety, which is based on the use of a combination of statistical and proactive models and takes into account the importance and priority of one or another means of passive anti-accident protection of road traffic. An algorithm for evaluating road traffic safety according to the developed methodology is proposed. The developed method of expert assessment of the level of road safety allows you to make informed management decisions regarding projects and programs on road safety due to the consideration of justified factors of influence and a relative reduction in the time for conducting an examination. It is proposed to combine the use of the developed methodology with the analysis of the established level of road traffic safety using the " bow-tie " or "petal" approach.
