Fundamentals of Transportation/Trip Generation/Problem2

 Problem:

Modelers have estimated that the number of trips leaving Rivertown (T_O) is a function of the number of households (H) and the number of jobs (J), and the number of trips arriving in Marcytown (T_D) is also a function of the number of households and number of jobs.

$$ T_O = 1H + 0.1J ;R^2 =0.9 \,\!$$

$$ T_D = 0.1H + 1J ;R^2 =0.5 \,\!$$

Assuming all trips originate in Rivertown and are destined for Marcytown and:

Rivertown: 30000 H, 5000 J

Marcytown: 6000 H, 29000 J

Determine the number of trips originating in Rivertown and the number destined for Marcytown according to the model.

Which number of origins or destinations is more accurate? Why?
