Question 1.
What is space mean speed?
Show hintHide hint
Think about how vehicle speeds are averaged differently based on time and position.
Question 2.
How does space mean speed differ from time mean speed?
Show hintHide hint
Consider the role of vehicle density in the calculations.
3Question 3.
What does space mean speed account for?
- Time taken by vehicles
- Spacial weighting of speeds
- Both a and b
Show hintHide hint
Remember the differences in how time and space influence speed calculations.
4Question 4.
Is space mean speed usually higher, lower or equal compared to time mean speed?
- True
- False
Show hintHide hint
Think about how slower vehicles impact the equations.
Question 5.
Given the following speeds: 70, 50, 30, 90, compute the space mean speed and discuss how slow speeds influence the overall result.
Show hintHide hint
Recall how harmonic averages work.
Question 6.
Analyze a hypothetical street with vehicles of speeds ranging from 15 to 60 km/h. How would the spacing affect the space mean speed? Create calculations for varied densities.
Show hintHide hint
Relate density to space mean speed computations.
