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.
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?
