Distribution of Fuel Efficiencies Computed for 100-mile Segments (All Trips with NGSWBTs Mounted on Both the Tractor and the Trailer) Fig. 76 and Fig. 77 show sample duty cycles for two randomly selected 100-mile segments corresponding to the Duals-Duals and NGSWBTs-NGSWBTs tire combinations, respectively. The fuel efficiencies calculated for these two 100-mile duty cycles correspond to one observation in each of the distributions shown in Fig. 72 to Fig. 75, respectively. Both correspond to freeway duty cycles; the first one representing operation under free-flow traffic conditions and the second one includes some traffic congestion intervals. The fuel consumed during these real-world duty cycles was used to compute one observation of the fuel efficiency for the two tire combinations. 89
