The role of public transport is growing as the cities and population increase. It can be said that the solution of the optimally aligned transport system in a broader sense at the state level and in the narrow sense at the city or settlement level requires detailed planning with adequate funding that will be sufficient to cover the necessary costs. In modern passenger transport, there is an unavoidable orientation towards the end-consumer service, or passengers, as well as care about his service satisfaction. In the modern era, the use of alternative fuels and hybrid drives in public transport is increasingly being developed. Replacement fuels are fuels that are replaced by the usual fuels. Every vehicle that uses more than one power source for its drive is called a hybrid vehicle. It is commonly believed that a hybrid vehicle in its propulsion structure contains at least two engines, one of which is an internal combustion engine, and another electric motor or a hydraulic motor. For this reason, the hybrid vehicle is a fairly complex system that allows individual drive components to operate in the most favorable mode of operation, that is, with the highest utilization, thus enabling significant fuel economy and reduced emissions of harmful gases by bringing the vehicle to a high efficiency level.
