Driving Safely with AI: An Overview of FollowNet for Car-Following Behavior
Practical Value of Car-Following Models:
- Reduces collisions: Safe following distances can decrease the number of accidents.
- Improves traffic flow: Predictable driving behavior leads to smoother traffic.
- Data-driven advancement: Machine learning models, like neural networks, are enhancing our understanding of traffic behavior.
Challenges and Solutions in Car-Following Models
Overcoming Limitations:
- Lack of standard data formats makes comparing models difficult.
- Existing datasets are limited and often don’t consider autonomous vehicles.
Introducing FollowNet:
- A benchmark that unifies data formats and evaluation criteria.
- Includes both traditional and advanced AI-driven models.
- Trains and evaluates models using five extensive public datasets.
