30.7. Time-space diagram

Try these first

1. 1.

   Define a time-space diagram.

   Hint

   Think about how position relates to time.

2. 2.

   What does a flat line in a time-space diagram indicate?

   Hint

   What happens to position if there is no movement?

3. 3.

   What does a time-space diagram show?

   • Vehicle interactions only
   • Vehicle movement over time and distance
   • Speed only

   Hint

   Think about what 'time' and 'space' together represent in vehicle motion.

4. 4.

   True or False: A flat line in a time-space diagram indicates a vehicle is moving at a constant speed.

   • True
   • False

   Hint

   What does 'flat' imply about speed?

5. 5.

   Based on a provided time-space diagram, calculate both the density and the volume of vehicles between specified points.

   Hint

   Break down the diagram into segments you can analyze step-by-step.

6. 6.

   Given a specific scenario, sketch a time-space diagram indicating various vehicle behaviors (e.g., standing still, accelerating, and decelerating) and explain how you derived those behaviors from the diagram.

   Hint

   Refer back to the definitions of slopes and curve shapes in the context of vehicle motion.
