The three haulers serving Duluth residential accounts with the largest market shares (>10%) are included separately. Because the reported/calculated market share of the three remaining haulers was so small, their count was combined into All Others. This minimizes the effect these haulers with small market shares have on the overall fuel use data because it is not known whether the dwelling unit's calculated for those small haulers are spread throughout the city or a small concentrated area. Even so, by calculating the fuel consumption of the combined smallest market share haulers, one can see that their consumption factor is substantially higher than any of the others. The calculated fuel consumption of the haulers in total, for a year at 55,532 gallons far exceeds the 18,915 gallons that of a single vehicle servicing all dwelling units at the time they pass by (representing a fuel consumption factor of 2.94). This demonstrates that the existing system uses an estimated 294% more fuel than a potential organized system. Rochester In the city of Rochester, the actual distance per household in Table 4-13 shows a distance of 86 feet. Comparing that distance to the field trial fuel consumption graph in Figure 4-6 below, shows a fuel consumption rate per household of 1.46 ounces per household, at actual distances. In comparing the observed average distances in Table 4-13 for Rochester, 292 feet, the corresponding consumption on Figure 4-6 is 4.45 ounces per household. Dividing the actual consumption of 4.45 ounces by the ideal consumption of 1.46 equals a consumption factor of 3.04. This consumption factor demonstrates that 304% more fuel was consumed by servicing only their subscribed households in that community than what would have been consumed if every household were serviced by that vehicle.
