6 sample questions

Question 1.
What is distance headway?
Show hintHide hint
Think about the gap or space between cars.
Question 2.
How would you calculate average distance headway from density?
Show hintHide hint
If density is high the distance will be short!
3Question 3.
What defines distance headway?
- Spacing between two vehicles
- Time taken for a vehicle to pass
- Number of vehicles in an area
Show hintHide hint
Reflect on what 'headway' implies.
4Question 4.
True or False: Higher density often results in longer distance headway.
- True
- False
Show hintHide hint
Think about how close cars get as density increases.
Question 5.
In a traffic simulation, the density is observed to be 80 vehicles per km. If a new regulation permits a minimum distance headway of 15 meters, is this acceptable?
Show hintHide hint
Figure out the spacing and compare it to regulations.
Question 6.
If you were an engineer tasked with redesigning a section of road with high traffic density, how would you address the issue of distance headway to improve safety?
Show hintHide hint
Think about physical changes that can lead to safer driving distances.
