Summary: Testing whether mixed driver anticipation best damps traffic shockwaves when incidents arrive in bursts of intermediate persistence.

Traffic breakdown is shaped not only by vehicle rules but also by how incidents cluster in space and time. This experiment asks whether a heterogeneous mix of anticipatory driving behavior can suppress incident-driven shockwaves most effectively when disruptions occur in bursts that are neither too isolated nor too persistent.

The model extends Nagel-Schreckenberg traffic dynamics with clustered incidents and driver-to-driver variation in anticipation. It compares resulting congestion patterns across persistence regimes to test for a nonmonotone window in which mixed anticipation provides the strongest damping of shock propagation.

That makes the experiment about interaction between incident statistics and behavioral diversity. Instead of asking whether anticipation helps on average, it asks when heterogeneity in anticipation helps the most.

Method: Repeated Nagel-Schreckenberg traffic simulations with clustered incidents and heterogeneous anticipation parameters, compared across incident-persistence regimes.

What is measured: Shockwave strength, congestion persistence, incident-cluster effects, and performance of mixed-anticipation traffic relative to more uniform behavior.
