32.2.2. Measurements over short section

Try these first

1. 1.

   What is the primary purpose of the enoscope?

   Hint

   Think about how it tracks time for vehicles.

2. 2.

   What does an inductive loop detector do?

   Hint

   Remember its placement in the road and the technology it uses.

3. 3.

   What is the base length used when measuring with an enoscope?

   • 10-20 meters
   • 20-40 meters
   • 30-90 meters

   Hint

   It’s the range specified for using this tool.

4. 4.

   True or False: Inductive loop detectors are not affected by the presence of heavy vehicles.

   • True
   • False

   Hint

   Consider issues of signal interference.

5. 5.

   Design a traffic study for a new road segment of 1km. Choose appropriate measurement methods and justify your choices.

   Hint

   Consider both short and long-term data needs.

6. 6.

   Evaluate an existing speed measurement case where an inductive loop showed discrepancies on a highway. Suggest potential factors affecting its accuracy.

   Hint

   Think about where errors may arise in data collection.
