Seattle's Department of Transportation modernized 40 traffic signals across the University District under MICMA (Multimodal Integrated Corridor — Mobility for All), a $4.09M federally funded programme completed in 2025. It added transit signal priority, bike detection and accessible pedestrian signals, and ran a peer-to-peer adaptive system at six signals on 15th Avenue NE that retimes lights from live traffic data.

Scale🏘️ District

🎓 Lesson

The adaptive-signal layer was a deliberately small pilot — six intersections on one corridor — bolted onto a broader signal-modernization grant, not a citywide adaptive rollout.
