Given a speed-density graph showing both linear and non-linear relationships, hypothesize how driver behavior might affect speed during peak traffic hours.
💡 Hint: Consider how different driving styles might contribute to overall traffic dynamics.
Imagine a scenario where a new traffic policy has been implemented to reduce density. Predict the changes in speed-density dynamics after implementation.
💡 Hint: Think about how fewer cars on the road can enhance overall traffic movement.
