Resumen
Developing an objective approach to take decisions aiming at reducing the number of injuries and damage inflicted by the road traffic incidents and accidents has become a top priority issue. A rational solution deals with setting up an intelligent road safety expert system comprising a complex software system that allows gathering the knowledge and applying it to improve road safety control. The methods to assess comprehensively the road traffic safety status were developed. The status is determined according to the behavior of traffic participants and conditions of the road facilities. The paper suggests using the theory of fuzzy sets as the most rational research tool.
