Traffic Signal Operations
Manage your traffic signals from start to finish with the Flow Platform
Aging signals, limited visibility, and reactive management—traffic signals are in crisis
Across the U.S., traffic signals are often treated as “set-and-forget” infrastructure — but the consequences are real. Most signals aren’t actively monitored, and outdated timing plans lead to unnecessary congestion, wasted fuel, and frustrated drivers. Agencies face mounting pressure to modernize operations, but lack the data, tools, and time to do it effectively.
A Smarter Future for Every Signal
Signals shouldn’t be silent, disconnected, or reactive. The future is a fully visible network—where every intersection is monitored in real time, issues surface automatically, and timing adapts dynamically to live conditions. Vehicles move predictably, delays shrink, and signals actively improve safety, flow, and reliability. This is the new standard for how signal systems should work—and it’s already taking shape.
01
Capture Real-Time and Historical Data
Traffic Signal data is continuously aggregated from the signals themselves, and connected vehicles into a unified platform. Manual exports disappear, and data gaps shrink, creating a real-time foundation for performance and planning.
02
Identifying Issues Instantly
Flow catches signal issues like excessive delays and queues, broken signal equipment instantly. With issues found faster they can be fixed before they create problems for drivers. That means fewer unexpected waits, less stop-and-go, and a better, more predictable trip—without the daily frustration.
03
Real-Time Signal Optimization
Live signal state monitoring, dynamic timing adjustments, and corridor-wide visibility give operators the tools to respond in real time. With better coordination and faster resolution, travel delays can be reduced by up to 30%.
04
Communicate Signal Data to Every Vehicle
Flow delivers live signal timing to vehicles—helping drivers glide through greens, avoid hard stops, and make safer decisions at every intersection. The result: fewer delays, smoother trips, and real savings on fuel and frustration.

Current Experience
Agencies often rely on scheduled retiming cycles or public calls for proposals to determine where to retime signals. As a result, retiming decisions are frequently driven by arbitrary timelines or the most vocal complaints rather than actual network need. This approach risks prioritizing the wrong intersections while more critical issues go unaddressed. With limited resources, mistargeted retiming can lead to thousands of dollars wasted per intersection—or the same amount in ongoing costs at problem locations that remain unresolved.
Flow Labs
Flow Labs provides complete visibility across the signal network through continuous performance measurement. Using the Cerberus module, agencies generate custom health scores and automatically identify signals showing the greatest decline in performance or traffic pattern changes. This enables agencies to prioritize retiming based on actual operational need, not guesswork—delivered in simple, daily reports that take seconds to configure.
