You are given the socioeconomic data for the Jeffersonville Transportation Study Area, as follows.
Population = 72,173
Area = 70 sq mi
Registered vehicles = 26,685
Single-family housing units = 15,675
Apartment units = 7,567
Retail employment = 5,502
Nonretail employment = 27,324
Student attendance = 28,551
Average household income = $17,500
Transportation analysis zones = 129
The results of the cross-classification analysis are as follows.
Total trips produced for study area = 322,150 per day
