Ok, I need a new legend for this one. All I did was take the AADT in a section and divide it by the number of through lanes in that section.
Legend:
White = 0 to 2,000
Grey = 2,001 to 3,500
Blue = 3,501 to 5,000
Green = 5,001 to 6,000
Yellow = 6,001 to 7,000
Orange = 7,001 to 8,000
Red = 8,001 to 9,000
Purple = 9,001 to 10,000
Brown = 10,001 to 12,000
Black = 12,001+
Highways listed by busiest section for AADT/lane:
125
102
101
107
105
103
104
118
106
142
162

I'm going to change "busiest" to "most crowded" for this, because that's (kind of) what this is a measure of.
