Question 1.
What does the speed-density diagram illustrate?
Show hintHide hint
Think about how these two factors can influence each other.
Question 2.
Define free flow speed.
Show hintHide hint
Consider the conditions when cars can move freely.
3Question 3.
What happens to the speed of vehicles as density increases?
- Speed increases
- Speed decreases
- Speed remains the same
Show hintHide hint
Think about how packed traffic behaves.
4Question 4.
True or False: The free flow speed is defined when vehicle density is at its maximum.
- True
- False
Show hintHide hint
Recall the definitions of free flow and jam conditions.
Question 5.
Given a speed-density graph showing both linear and non-linear relationships, hypothesize how driver behavior might affect speed during peak traffic hours.
Show hintHide hint
Consider how different driving styles might contribute to overall traffic dynamics.
Question 6.
Imagine a scenario where a new traffic policy has been implemented to reduce density. Predict the changes in speed-density dynamics after implementation.
Show hintHide hint
Think about how fewer cars on the road can enhance overall traffic movement.
