Real-time data was collected from existing routes in the city using a stop-watch. By mathematical and software (Excell), collected data were analyzed. Then, according to the local information such as population density, waste generation capita, routes and also the application of mathe-matical relationships, the optimum routing vehicle was designed.
Referring to results, the optimize way was selected and the results showed the vehicle costs and shift workers have been reduced about 25 and 50%, respectively. The result of present study is suggested that the 78 storage tanks with a volume about 550 and 660 liter for residential and commercial areas.
