... It publishes a monthly Truck Tonnage Report, which is used as input to FTR and ACT Research monthly reports. Since ton-miles is an important characteristic to track for existing and future fuel use regulations, ATA may be an excellent source going forward (see Figures 4A-12 to 4A-14 and Table 4A-3)
