Resumen
For a few years attempts have been made to introduce electric-powered buses to public transportation system. In order to solve this problem rationally, in dependence of local public transport system conditions, models of technical, organizational, economic and ecological links enabling optimal choice of type of propulsion for particular bus line is developed. Technical solutions to enable fully electric busses should be evaluated whether they reflect the prerequisites and requirements of the participating public transport companies. The paper presents a method for evaluating transport system in accordance with the principles of cost-benefit analysis that allows to answer the questions related to the cost-effectiveness of the use of electric drive buses in urban public transport. The model can be used to analyse and design the services of urban public transport in terms of costs generated by the bus fleet equipped with various types of drive. The article presents procedures used to determine the costs used in the method of evaluation of the proposed solutions. The ultimate goal is to find the best technical solution for local public transport companies depending on their real input data (timetable, vehicle operation plan, etc.), which in most cases may mean minimising economic effects, like investment and operational costs.
