Question 1.
Define Time Mean Speed (TMS).
Show hintHide hint
Think about averages calculated over periods.
Question 2.
What is Space Mean Speed (SMS)?
Show hintHide hint
Consider how space and distance come into play.
3Question 3.
What is the primary difference between TMS and SMS?
- A) TMS is calculated using time intervals
- while SMS uses spatial distribution.
- B) TMS includes only fast vehicles
- while SMS does not.
- C) TMS is always less than SMS.
- D) TMS accounts for vehicle spacing only.
Show hintHide hint
Remember which speed focuses on time vs. space.
4Question 4.
True or False: Time Mean Speed is always less than or equal to Space Mean Speed.
- True
- False
Show hintHide hint
Think about the definitions of each speed.
Question 5.
A traffic study shows speeds of vehicles at a junction: 25, 30, 35, 45, and 50 km/h. Calculate both TMS and SMS. Discuss which speed is most relevant to traffic management.
Show hintHide hint
Setting up averages is key!
Question 6.
Discuss how changes in speed limits on a road would affect TMS and SMS. Provide theoretical examples illustrating potential differences.
