DETERMINATION THE NORMS OF FUEL CONSUMPTION FOR BUSES IN THE PUBLIC TRANSPORTATION IN REAL CONDITIONS OF EXPLOITATION

Determination the norms of fuel consumption for the buses are operating in the public transportation system is an important indicator of exploitation, which should serve as a benchmark when analysing fuel economy of bus. Viewed from a strategic point of business, optimization of fuel consumption is a significant step in the program of measures relating to reducing the financial expenses of the company. Lower consumption of fuel means better environmental performance for vehicles that are manifested through lower emissions as an important issue in terms of environmental protection and sustainable development. In this paper presents an example of determining the norms of fuel consumption for the largest group of articulated buses ‘'Solaris Urbino 18'', which are in fleet JKP GSP ''Beograd'' (City Public Transport Company “Belgrade“). The norms were obtained by statistical analysis of the representative sample lines where the buses in operation. Norms of consumption was obtained on the basis of interval estimates of the mean value fuel consumption for selected lines and establishing a correlation dependence of the fuel consumption and exploitation speed of bus
