Practice Questions
Test your understanding with targeted questions
What is the primary purpose of the doubly constrained growth factor model?
💡 Hint: Think about why we need to manage trips coming from and going to different locations.
Define what is meant by 'balancing factor'.
💡 Hint: Consider how we might need to correct our data to fit actual numbers.

What does the doubly constrained growth factor model rely on?
💡 Hint: Recall the necessity of both origins and destinations.
True or False: The doubly constrained model is less accurate than the singly constrained model.
💡 Hint: Consider the factors applying in both models.

Challenge Problems
Push your limits with advanced challenges
Given productions of 150 trips and attractions of 150 trips for three zones, calculate the balancing factors and determine the trips in a trip matrix using the doubly constrained model.
💡 Hint: Start from setting b to 1, and remember to frequently update the trip totals based on calculated factors.
Analyze a scenario where only one constraint (trip production) is known. Discuss the effects on trip distribution and the model’s accuracy.
💡 Hint: Consider the implications of having incomplete data on modeling and trips.
