Question 1.
How is density calculated in traffic engineering?
Show hintHide hint
Remember the formula k = n/x.
Question 2.
What units are typically used to express traffic density?
Show hintHide hint
Think about common units of distance.
3Question 3.
What is density in traffic engineering?
- Number of vehicles per distance
- Speed of vehicles
- Time taken by vehicles
Show hintHide hint
Think about what density measures in terms of spatial arrangement.
4Question 4.
True or False: Higher density indicates less space for maneuverability.
- True
- False
Show hintHide hint
Consider the implications of close vehicle spacing.
Question 5.
A highway segment has a speed limit of 60 km/h. If the density is 40 vehicles/km at peak time, calculate the expected flow in vehicles per hour.
Show hintHide hint
Use the flow formula and be careful to convert all units properly.
Question 6.
If a road sees increasing density to 100 vehicles/km, and the speed drops to 30 km/h, what might happen to flow? Estimate the flow under these conditions.
Show hintHide hint
Think about how high density vs. speed impacts overall traffic movement.
