Challenge Problems

Push your limits with challenges.

Question 1

A theory predicts that at a certain intersection, vehicles surge at specific intervals modeled as delta functions. If vehicles are expected at x=3 at times t=1, 3, and 5, write the equation showing this scenario.

💡 Hint: Sum the delta functions for each time point.

Question 2

Given a highway with entry points modeled as delta functions at different positions over time, explain how to analyze the impact of an unexpected event, like an accident, on traffic flow.

💡 Hint: Consider implementing a simulation to visualize the changes.
