The Model for Evaluating Criteria Describing the Internal Safety of a Railway Trip by International Train

Abstract

The transport system must increase the mobility of the national population, gross domestic product (GDP) and remain environmentally friendly and safe. Rail transport is increasingly becoming popular for both long-distance freight and passengers. This trend is affected by an increase in safety travelling by train, which significantly improves the quality of the trip. The paper presents a mathematical model that allows calculating a share of the indicator for the quality of traveling by international train, which depends on the impact of criteria for internal safety in the carriage. The weights of eight sub-criteria for the main criteria falling into group D have been determined applying the Analytic Hierarchy Process (AHP) method, whereas their variables have been estimated using original formulas. The resolved numerical example admits that the introduced model is suitable and convenient to be employed in practice assessing the quality of the international train in a single number. The actual data on the international train Vilnius-Moscow indicating the adequacy of internal security measures have been used for the numerical example.
