How Passenger Transport is Developing in Bulgaria in the Conditions of a Dynamic Changing Environment?

The current study seeks to establish the preferences of Bulgarians through exploring how passenger transport in Bulgaria developed from 2012 to 2022. On a theoretical level, the characteristics of this sector are described, such as types of passenger transport vehicles. The research interest is aimed at tracking the dynamics behind all the options for passenger carriage forming the supply of the transport market in Bulgaria: by rail, bus, air, water, and urban electric transport. To achieve this objective, the parameters of activity in the passenger transport segment are used as the main measures – number of passengers, passenger-kilometres and average distance travelled. During the studied period, passenger transport in Bulgaria developed at variable rates and was influenced by environmental factors. The mode of transport most affected by the pandemic in 2020–2021 was by air. A decrease in the total number of passengers and overall performance for 2022 compared to 2012 can be observed. This decline is due to a decrease in bus and rail transport indicators. The study has established that Bulgarians prefer traveling by bus to other public transport alternatives. Although the absolute number of vehicles has decreased in this segment, it has the largest relative share according to the indicators of transported passengers and performed work as part of the total transport activity in the country. In a practical respect, attention is focused on modern solutions related to information and communication technologies, as well as some opportunities to attract more public transport passengers. The author also draws attention to some EU initiatives in the field of air and maritime transport concerning Union-wide energy policy.
