Caltrans daily detection trend 10 September 2026: we improved our infrastructure to index new sites much sooner, often on the day they go live, so the cohort this share is measured against changes here. 5% 2% 0% Sep Aug 30 · 0 / 92865 = 0.0% Aug 31 · 0 / 90627 = 0.0% Sep 1 · 0 / 92269 = 0.0% Sep 2 · 0 / 98368 = 0.0% Sep 3 · 0 / 93599 = 0.0% Sep 4 · 0 / 89509 = 0.0% Sep 5 · 0 / 93397 = 0.0% Sep 6 · 1 / 81844 = 0.0% Sep 7 · 0 / 79235 = 0.0% Sep 8 · 0 / 72177 = 0.0% Sep 9 · 0 / 68654 = 0.0% Sep 10 · 0 / 72307 = 0.0% Sep 11 · 0 / 77796 = 0.0% Sep 12 · 0 / 51405 = 0.0% Sep 13 · 0 / 53648 = 0.0% Sep 14 · 0 / 53422 = 0.0% Sep 15 · 0 / 52973 = 0.0% Sep 16 · 0 / 53705 = 0.0% Sep 17 · 0 / 51722 = 0.0% Sep 18 · 0 / 48252 = 0.0% Sep 19 · 0 / 41122 = 0.0% Sep 20 · 0 / 40603 = 0.0% Sep 21 · 0 / 46525 = 0.0% Sep 22 · 0 / 50107 = 0.0% Sep 23 · 1 / 53112 = 0.0% Sep 24 · 0 / 48137 = 0.0% Sep 25 · 0 / 46431 = 0.0% Sep 26 · 0 / 97887 = 0.0% Sep 27 · 1 / 48210 = 0.0%

The shaded part of the chart is measured against a different set of sites.

Amber: on 10 September 2026 we improved our infrastructure so we can index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from that date. We record each site as it was when we found it.

The share is a proportion of whatever we were tracking at the time, so it can step at that line without the technology itself changing. For a single continuous measure, switch to launch platforms.
