31.7.3. Speed flow relation

Try these first

1. 1.

   What happens to flow when no vehicles are present on the road?

   Hint

   Think about the definition of flow.

2. 2.

   At what point do we expect to see maximum flow?

   Hint

   Consider the relationship between speed and flow.

3. 3.

   What is the maximum flow associated with?

   • Zero Speed
   • Free Flow Speed
   • Intermediate Speed

   Hint

   Consider what happens during peak flow scenarios.

4. 4.

   True or False: Flow becomes zero during congestion.

   • True
   • False

   Hint

   How does congestion affect movement?

5. 5.

   Given three different highway scenarios with varying traffic densities, calculate the points at which each would achieve maximum flow.

   Hint

   Break down each traffic situation separately, considering vehicle dynamics.

6. 6.

   Evaluate the effectiveness of a proposed speed limit change on a congested highway and predict the outcomes on flow rates.

   Hint

   Consider how changing limits might impact overall flow rates.
