LaneLedger

LaneLedger is a web + mobile app for cities and traffic engineers to quickly pinpoint what actually caused a traffic breakdown on a corridor: a signal timing issue, a crash, illegal curb activity, construction staging, or a special event. It combines existing data sources (signal controller logs, probe speed data, 311/dispatch feeds, work-zone schedules) into a single incident timeline and generates a defensible “before/during/after” congestion report. The MVP focuses on post-incident forensics rather than real-time control, because most agencies can’t safely change timing on the fly and procurement cycles are slow. Users select a corridor and time window, the system auto-aligns data streams, flags anomalies (e.g., split failures, queue spillback), and outputs a shareable PDF plus a linkable dashboard. It’s designed to reduce finger-pointing between agencies, contractors, and consultants and to speed up targeted fixes.
