34.4.2. Follow-the-leader model

Try these first

1. 1.

   What does the Follow-the-leader model focus on?

   Hint

   Remember the significance of space in traffic interactions.

2. 2.

   Define the sensitivity coefficient (τ).

   Hint

   Think about how quickly drivers need to respond to speed changes.

3. 3.

   What key factor does the Follow-the-leader model emphasize?

   • Distance
   • Speed
   • Both Distance and Speed

   Hint

   Think about the interactions between vehicles on the road.

4. 4.

   True or False: The sensitivity coefficient indicates the time it takes for vehicles to respond to changes.

   • True
   • False

   Hint

   Revisit the definitions of the key concepts.

5. 5.

   Given a vehicle moving at 50 MPH with a safe distance of 1.5 car lengths. Calculate the required distance for a vehicle traveling at 75 MPH using the Follow-the-leader model assumptions.

   Hint

   Consider the relationship between speed and distance as directly proportional as per the model.

6. 6.

   Propose a scenario where following the leader may not work effectively in real traffic and explain why.

   Hint

   Think about the challenges drivers face in chaotic traffic situations.
