8.3.1. Uniform growth factor

Try these first

1. 1.

   If the original number of trips is 200 and the growth factor is 1.2, how many trips will there be after growth?

   Hint

   Multiply the original number of trips by the growth factor.

2. 2.

   List two advantages of the uniform growth factor method.

   Hint

   Think about why it’s beneficial to have a straightforward method.

3. 3.

   What does the uniform growth factor model use to expand trip estimates?

   • Single growth rate
   • Multiple growth rates
   • Average trip distance

   Hint

   Consider how the method described applies to trip distribution.

4. 4.

   True or False: The uniform growth factor method is suitable for long-term planning.

   • True
   • False

   Hint

   Think about whether this method can adapt to changing conditions.

5. 5.

   Create a trip matrix for three zones with the following original trips: 100, 200, and 150. A growth factor of 1.5 should be applied across. Analyze the distribution and suggest implications for urban planning.

   Hint

   Consider how trip increases can affect transportation models.

6. 6.

   Discuss how you would adapt the uniform growth factor model for a region experiencing rapid urbanization. What changes would you make?

   Hint

   Think about the factors that contribute to unique growth patterns.
