Table 4-14 shows that the composite fuel consumption factor in the city of Rochester is 2.50, <br />which is 250% more fuel is estimated to be used than in an organized collection system. This is <br />lower than calculated from field observations because one hauler was reported to have a more <br />significant market share (59.5%) than was observed in the actual Rochester field observations. <br />Woodbury <br />In the city of Woodbury, the actual distance per household in Table 4-15 shows a distance of 123 <br />feet. Comparing that distance to field trial fuel consumption graph in Figure 4-7 below, shows a <br />fuel consumption rate per household of 2.09 ounces at actual average distances. In comparing <br />the field observed distances in Table 4-16 for Woodbury, 316 feet, the corresponding <br />consumption on Figure 4-7 is 4.66 ounces per household. By dividing the actual consumption of <br />4.66 ounces by the ideal consumption of 2.09 equals a consumption factor of 2.22. This fuel <br />consumption factor demonstrates that 222% more fuel was consumed by servicing only their <br />subscribed households in that community than what would have been consumed if every <br />household were serviced by that vehicle. <br />Figure 4-7 Fuel Consumption - City of Woodbury <br />N <br />0 5 <br />Q <br />0 <br />aD 4 <br />C. <br />m <br />E 3 <br />3 <br />c <br />0 <br />U <br />� 2 <br />3 <br />LL <br />0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 <br />LO o M o LO o LO o U') o LO o <br />N N M M V 7 LO LO CO CO � <br />Distance between Stops (ft.) <br />R - Analysis of Waste Collection Service Arrangements.doc Foth Infrastructure & Environment, LLC • 123 <br />June 2009 <br />
