On the problem of assessing and analyzing traffic accidents risk on the rail transport

The problem of assessing and analyzing traffic accidents risk on the rail transport is considered. Two functions of the integral risk are proposed that allow assessing danger of transportation along the entire route of a transport. The probability of an unfavorable event occurring during transportation and the expected damage are chosen as such functions. The concept of assessing probability and damage from unfavorable events during the freight trains transportation is proposed. A meaningful example of calculating integral risk functions is given on the basis of previously investigated statistics on the freight trains transportation and unfavorable events that occurred with them.
