Try these first

1. 1.

   What is traffic flow?

   Hint

   Think about how many vehicles pass a specific point in a set time.

2. 2.

   Name one method used for collecting traffic data at a point.

   Hint

   Consider how you might keep track of cars at a stoplight.

3. 3.

   What is the main reason traffic studies rely on field data?

   • A) Laboratory conditions are preferred.
   • B) Drivers cannot be simulated accurately in labs.
   • C) Field data is less expensive.

   Hint

   Consider the variability in driver actions.

4. 4.

   True or False: The moving observer method allows for discrete data collection.

   • True
   • False

   Hint

   Think about continuous vs. static measurement.

5. 5.

   If you were to design a new method for collecting traffic data, combining both manual and automated techniques, what factors would you consider regarding accuracy and efficiency?

   Hint

   Think about how each method addresses the limitations of the other.

6. 6.

   Analyze a scenario where a city has high traffic flow but low density. What implications might this have for traffic management?

   Hint

   Consider the relationship between flow, density, and safety!
