Abstract:

In recent years, there has been a significant increase in the number of buses operated by urban public transport
companies powered by alternative fuels and equipped with alternative drive systems. In addition to economic factors,
operators should also take environmental aspects into account when purchasing new vehicles. In this case, a useful
criterion for selecting a vehicle is the Life Cycle Cost (LCC), which, in addition to the cost of purchasing a bus,
takes into account the necessary expenses associated with its maintenance, operation, decommissioning, as well as
emissions costs. This paper presents a study of the LCC values, estimated for the entire bus fleet based on several bus
replacement variants, taking into account different shares of alternative buses in the transport fleet. Analyses have
shown that replacing conventional buses by the compressed natural gas (CNG) powered buses will reduce life cycle cost
by 27% compared to the LCC level in 2019. Increasing the share of electric buses in the fleet will significantly reduce the
level of emissions of harmful substances contained in exhaust gases
