Research Regarding the Risk Assessment During Motor Vechicle Collisions between Automobiles and Pedestrians

In the proposed article the authors suggest a short historical review regarding the emergence of a risk of an incident occurring during the application of technological operations or human activity. This is a current problem concerning all existing risky technical systems (RTS). By RTS are implied land, air, and naval transport, production or financial activity, energy systems, and others. Definitions for the term "risk" are made according to existing European and Bulgarian legislation. Presented here is a formula to calculate the risk of low quality execution of various operations (technical, economical, financial, military, political, etc.) for a certain time frame. The elements of risk are determined during the analysis of the probability of a road traffic accident (RTA) between vehicles and pedestrians occurring. The applied scientific value of the report is determined according to the established approach for road traffic accident risk assessment, based on statistical information about traffic incidents in the Republic of Bulgaria.
