Show hintHide hint
Recall the acronym 'SFTD'
Question 2.
Name a common device used for traffic data collection.
Show hintHide hint
Think of technology that counts vehicles.
3Question 3.
What is the fundamental equation relating flow, speed, and density?
Show hintHide hint
Remember the relationship q = u.k.
4Question 4.
True or False: Data cannot be collected in a laboratory environment for traffic studies.
- True

Show hintHide hint
Think of real-world behavior.
Question 5.
Conduct a theoretical moving observer study over a mile stretch of road. Project how many vehicles would pass in peak hours if density is 150 vehicles/km and the average speed is 40 km/hr.
Show hintHide hint
Use the fundamental equation relating flow, speed, and density.
Question 6.
Assuming a data collection session resulted in an inductive loop detecting 500 vehicles in one hour at peak time, how might this influence traffic signal timing?
Show hintHide hint
Think about how signal adjustments are made based on volume.
