Popis | We analyze the performance of public transport companies in 19 Czech cities by Network Data Envelopment Analysis using two-stage approach. Network DEA models are often used for unstorable commodities, where technical efficiency is evaluated in the first stage (transformation of inputs into production) and service effectiveness is evaluated in the second stage (transformation of production into consumption). The unstorable feature of transportation service is obvious, the unocuppied seats in the vehicle's past journey cannot be sold in the future. So in order to capture the overall performance of the transit company it is necessary to treat the commonly used performance indicators such asvehiclekilometersorseatkilometersasanintermediatemeasureonly.Bymeansof two-stagemodelweidentified one company (Public Transport Company of Liberec) as overall effective. We also derived recommendations for other companies using frontier projections. |
