30.7.1. Single vehicle

Try these first

1. 1.

   What does a horizontal line on a time-space diagram represent?

   Hint

   Think about what it means for the vehicle not to move.

2. 2.

   If a vehicle is speeding up, what does its representation on the time-space diagram look like?

   Hint

   Pay attention to the steepness of the line.

3. 3.

   What does a steep slope on a time-space diagram represent?

   • A stationary vehicle
   • A vehicle speeding up
   • A vehicle slowing down

   Hint

   Think about the angle of the slope.

4. 4.

   True or False: A horizontal line on a time-space diagram indicates a vehicle is moving.

   • True
   • False

   Hint

   Consider what movement looks like on the graph.

5. 5.

   Design a comprehensive time-space diagram for a vehicle that starts from rest, accelerates to maximum speed, maintains speed, then decelerates and comes to a stop. Provide explanations for each phase.

   Hint

   Label your graph clearly to show each phase of movement.

6. 6.

   Assess the impact of a time-space diagram that shows multiple vehicles moving at different speeds. How would this affect traffic flow and road design strategies?

   Hint

   Consider how patterns of vehicle movement influence overall traffic performance.
