8. Trip Distribution

Try these first

1. 1.

   What is the primary purpose of trip distribution?

   Hint

   Think about what happens after trips are generated.

2. 2.

   What does a trip matrix represent?

   Hint

   Consider the format in which trips are organized.

3. 3.

   What is the purpose of the trip matrix in transportation modeling?

   • To visualize traffic flow
   • To allocate trips from origins to destinations
   • To analyze road safety

   Hint

   What does the trip matrix contain?

4. 4.

   True or False: The gravity model only considers the population size of the originating and destination zones.

   • True
   • False

   Hint

   Consider what other factors affect the attraction of trips.

5. 5.

   Using the growth factor model, estimate the trip distribution for a city with three zones if the current trips are 100, 200, and 300, and the growth factor is 1.5.

   Hint

   Apply the growth factor uniformly to each zone.

6. 6.

   In a city using the gravity model, how would changes in transportation funding affect trip distribution? Illustrate with an example.

   Hint

   Think about how improvements affect costs and attractiveness.
