- A second site at Bank Street went live this week as officials begin outfitting all 12 local signals and one in Fairfax.
- The Transportation Authority of Marin grant covers installation and the first two years of service, with per‑intersection installation estimated at $10,000–$15,000 and annual operating costs ranging from about $4,000 to $12,000.
- San Anselmo contracted an outside consultant to compare historical and current traffic data to independently verify the company’s findings.
