Question 1.
What is the main purpose of the moving observer method?
Show hintHide hint
Think about what makes this method different from stationary measures.
Question 2.
Name two parameters that can be calculated using the moving observer method.
Show hintHide hint
Consider what quantities are observed during traffic flow.
3Question 3.
What is the primary goal of the moving observer method?
- To measure static vehicle counts
- To measure traffic flow parameters dynamically
- To enhance speed limits
Show hintHide hint
Think about how the observer interacts with traffic.
4Question 4.
True or False: The moving observer method requires the observer to be stationary.
- True
- False
Show hintHide hint
Recall the definition of the method discussed.
Question 5.
If a moving observer counts 120 vehicles passing by in one direction and encounters 30 vehicles while moving opposite, calculate the flow if the observer takes 15 minutes for the test.
Show hintHide hint
Ensure your time conversion is correct.
Question 6.
An observer measures a flow of 720 veh/hr and the average speed of traffic is 40 km/hr. Determine the density and discuss how it reflects the efficiency of road use.
Show hintHide hint
Think about what high density means for drivers on the road.
