14 The truck percentage includes diesel and gasoline trucks as well as buses.
15 2006 truck percentages are based on 2006 KYTC traffic counts; future truck percentages have been calculated using KYTC agreed-upon statewide averages by highway type (HPMS functional class)
16 31,900 of this downtown river crossing AADT would cross at the east end if a bridge were available.
17 42,000 of this downtown river crossing AADT would cross at the east end if a bridge were available.
18 42,000 additional AADT would be crossing downtown if the east end bridge were not available.
19 Although the 2020 AADT for the east end bridge is greater than the 2014 AADT, the 2014 AADT is considered the worst-case due to regulation and technology induced emission reductions between 2014 and 2020.
20 It should be noted that of this 61,400 AADT 19,400 is induced travel
