where XX represents the State Code, YY represents the Year.

  1. Number of Lanes in Direction Indicated.

    If column 37 into Old ASCII File has a value greater 4 or column 38 into Old ASCII File has a value greater 2 then a value into New ASCII File column 16 is equal to the value into Old ASCII File column 36. Otherwise, a value into New ASCII File column 16 is equal to the blank.

  2. Method of Vehicle Classification.

    If column 38 into Old ASCII File has a value less 3 then a value into New ASCII File column 22 is equal to to the value into Old ASCII File column 38.

    If column 38 into Old ASCII File has a value equal to 3 or 4 then a value into New ASCII File column 22 is equal to 1.

    If column 38 into Old ASCII File has a value equal to 5 or 6 then a value into New ASCII File column 22 is equal to 2.

    If column 38 into Old ASCII File has a value equal to 7 or 8 then a value into New ASCII File column 22 is equal to 3.

  3. Sample Type for Truck Weight.

    The value in New ASCII File column 26 is equal to T if "Card 4" and "Card 7" exist.

  4. Method of Truck Weight

    If column 37 into Old ASCII File has a value less 5 then a value into New ASCII File column 28 is equal to a value into Old ASCII File column 37.

    If column 37 into Old ASCII File has a value equal to 5 or 6 then a value into New ASCII File column 28 is equal to 4.

    If column 37 into Old ASCII File has a value equal to 7 or 8 then a value into New ASCII File column 28 is equal to 5.
