34.4.1. Basic Philosophy

Try these first

1. 1.

   Define the term 'Stimulus' in the context of car-following models.

   Hint

   Think about what would make a driver react on the road.

2. 2.

   What is the basic equation describing the relationship between response and stimulus?

   Hint

   Recall the acronym S-R model.

3. 3.

   What is the basic equation representing the stimulus-response concept in traffic flow?

   Hint

   Remember the S-R model.

4. 4.

   True or False: The stimulus in a car-following model can be affected only by speed.

   • True
   • False

   Hint

   Consider the multiple factors that may influence driving decisions.

5. 5.

   Simulate how a driver responds to sudden braking lights appearing in front. Use variables like speed and distance to explain the expected acceleration.

   Hint

   Think about the reaction time in this scenario.

6. 6.

   Develop a new car-following model that incorporates driver agitations, such as driving too closely to the vehicle ahead. What changes would need to be made?

   Hint

   Consider how intertwined psychology is with these mechanical responses.
