Collection and transportation within the system of solid waste management may
account more than 60% of the overall budget, most of which is for fuel
costs. Furthermore, municipal vehicles have great environmental impact
through exhaust gases emissions. The aim of this research was to estimate
the potential for reduction of fuel consumption and thus the emission of CO2
through the communal vehicles route optimization. General methodology for
route optimization is also presented. For the area under study, detailed
field experimental research in the City of Kragujevac was conducted. Using
GIS and GPS technology, whole municipally infrastructure for waste
collection was scanned and all paths of communal tracks was recorded and
allocated in developed database. Based on experimental and numerical
results, one typical municipal vehicle route was analyzed by using ArcGis
software. The obtained result indicates 2700 km of possible savings per year
concerning one communal vehicle. In addition, the most fuel-economical route
was extracted and compared with the original route, and with the routes
extracted from criterions concerning the traffic time and shortest distance.
According to available information for the City of Kragujevac and the
results from this study, it was estimated that the total savings could be
20% in costs and the associated emissions.
