Analysis of safety of passenger transportation in modern and conventional buses operated in integrated municipal traffic and public transport management system

Abstract

The article is an attempt to answer the question how advanced technologies used in modern city buses, are reflected in the actual reduction of the number of road accidents and improving the safety of use. The analysis concerns the period 2013-2017 of implementation and exploitation of sustainable public transport in the city. These were modern buses Autosan Sancity 10LF and Mercedes-Benz Citaro 12 CNG as well as conventional structures Jelcz 120 M/4 12 CNG and Solaris Urbino 12 CNG. The level of threat to the safety of urban transport resulting from the number of collisions and accidents was examined. The assessment was carried out using the W3 indicator characterizing the level of transport system security risk caused also by the damage of bus systems in one year assessed: probability of failure of the analyzed P system (U*) and significance of damage to these bus systems to the risk of urban transport security O.
