ANALYSIS PIPELINE · PART 01
Detect the waves before tracing their origins.
Components—current lane/filter
Median duration—seconds
Median front span—miles
Complex topology—share of components
Advanced detector settings
Shown for reproducibility. These structural parameters should be varied in a later robustness study, after the critical-speed analysis.

Define the candidate search region
Start from the detector-derived onset seed, then adjust an asymmetric window around it. The rectangle updates in the wave chart above.

Interpretation: this rectangle is an investigation window, not a causal boundary. Vehicles that intersect it become candidates; attribution requires their preceding trajectories and behavioural evidence. For now, missing intervals remain connected and must not be interpreted as observed motion.
