30.3.4. Time mean speed and space mean speed

Try these first

1. 1.

   What does time mean speed indicate?

   Hint

   Think about measurements at a specific location.

2. 2.

   What is the space mean speed?

   Hint

   Consider measurements across a segment of a road.

3. 3.

   What is time mean speed?

   • Average speed over a section
   • Average speed at a point over time
   • Speed at which a vehicle is traveling currently

   Hint

   Remember, it’s focused on one point in time.

4. 4.

   True or False: Space mean speed can be understood as the average speed of vehicles in a certain section at a moment.

   • True
   • False

   Hint

   Think about how averages are calculated.

5. 5.

   A traffic study finds that the time mean speed is consistently higher than the space mean speed over various measurements. Discuss the potential reasons for this finding.

   Hint

   Consider the factors influencing congestion.

6. 6.

   You are conducting a traffic survey on a busy intersection. You find the time mean speed is 25 km/h during the day but increases to 50 km/h at night. Discuss factors that could explain this variation.

   Hint

   Think about how traffic density changes throughout the day.
