10.6.1. Incremental assignment

Try these first

1. 1.

   What is incremental assignment?

   Hint

   Think about how traffic is managed gradually.

2. 2.

   Define O-D pair.

   Hint

   They are crucial in calculating traffic flow.

3. 3.

   What is the primary method used in incremental assignment?

   • Incremental loading
   • All-or-nothing assignment
   • Equilibrium assignment

   Hint

   Think about how traffic is loaded onto paths.

4. 4.

   True or False: Incremental assignment results in a true equilibrium solution.

   • True
   • False

   Hint

   Reflect on the nature of an equilibrium situation.

5. 5.

   Create a model using incremental assignment for a small city with three O-D pairs. Show the allocations at each step and discuss the impact of recalibrating travel times.

   Hint

   Start with a clear initial allocation and track differences in travel times.

6. 6.

   Analyze a hypothetical situation where a tourist attraction opens in your city. Describe how incremental assignment could be applied to evaluate its impact on traffic and the possible errors that could occur.

   Hint

   Consider real-world variables such as peak hours and unforeseen events.
