Typical week

Day-of-week profiles reproduce and extend the September 2025 analysis over the complete collection period. Each line is a 15-minute median; the shaded band spans the 25th–75th percentiles.

Profile statistics include only direction-days with at least 95% expected five-minute samples. This avoids treating system downtime as low traffic. Percentile envelopes represent observed detector variability, not measurement confidence intervals.
