34.4. General motor’s car following model

Try these first

1. 1.

   What is the basic principle of car following?

   Hint

   Think about how cars behave in traffic.

2. 2.

   Define reaction time in driving.

   Hint

   Consider how quickly a driver can react to a brake light.

3. 3.

   What is the core concept of the General Motors car following model?

   • Follow-the-leader principle
   • Random spacing
   • Traffic speeds unrelated

   Hint

   Think about how vehicles behave on a highway.

4. 4.

   True or False: The sensitivity coefficient affects how quickly a driver will adjust to changes in speed.

   • True
   • False

   Hint

   Recall how drivers respond to a vehicle stopping ahead.

5. 5.

   Imagine you are simulating a traffic scenario with varying sensitivity coefficients. How would you adjust the model's parameters based on real-time data?

   Hint

   Think about the data you might collect.

6. 6.

   Create an alternative car-following model that considers external factors such as weather conditions and visibility. Describe how these factors might alter driver behavior.

   Hint

   Consider how driving differs under different weather conditions.
