Figure 4-3 Field Observations - Average Observed Distances <br />between Serviced Households versus Average <br />650 <br />600 <br />550 <br />500 <br />450 <br />400 <br />350 <br />d <br />LL 300 <br />250 <br />200 <br />150 <br />100 <br />50 <br />0 <br />Actual Distance between Households <br />Eagan Duluth Rochester Woodbury St Paul <br />4.9.4 MSW Collection Fuel Use <br />Eagan <br />During field observations in the city of Eagan, the average actual distance per household in Table <br />4-8 shows a distance of 118 feet. This was calculated using the ranges of actual distances by <br />area within the city from 79 feet to 155 feet, averaging 118 feet. The distances the haulers <br />actually drove during the field observation ranged from 129 feet to over 1,500 feet per household <br />with and average observed distance of 582 feet (see Table 4-9). Comparing that to the field trial <br />fuel consumption graph in Figure 4-4 below, it shows a fuel consumption rate per household of <br />2.01 ounces if serving households at the actual distances. In comparing the average observed <br />distances in Table 4-8 for Eagan, 582 feet, the corresponding consumption on Figure 4-4 is 6.05 <br />ounces per household. Dividing the actual consumption of 6.05 ounces by the ideal consumption <br />of 2.01 equals a fuel consumption factor of 3.01. This fuel consumption factor demonstrates that <br />301% more fuel was consumed by servicing only the observed households in that community <br />than what would have been consumed if every household were served by that vehicle as it drove <br />by. <br />112 •Foth Infrastructure & Environment, LLC R - Analysis of Waste Collection Service Arrangements.doc <br />June 2009 <br />
