Luminus
Probe-Based Signal Performance Measurement (PBSPM) Software
Traffic signal insights without any hardware or connectivity
Luminus used high-penetration probe data to provide signal insights at regional-scale without requiring any hardware deployment or connectivity. No hardware, no problem.
01
Proactive Signal Monitoring
Automatically surface and prioritize issues with Cerberus. Set intelligent alerts based on customizable thresholds across your network.
02
Instant, detailed analytics
Use Abacus to explore key signal performance measures—like control delay, arrivals on green, or queue length—with map-based navigation down to the phase and movement level.
03
Before-After Analysis in Seconds
Generate high-quality before-after reports with Litmus to evaluate project impact. Ideal for timing updates, safety improvements, or funding justification.
Built for the Work That Matters Most
The Flow Platform goes beyond showing you data — it helps you get real work done, faster and smarter. Whether you're tackling signal retiming, performance evaluations, or before-after analyses, the Flow platform is designed to support your most critical traffic signal use cases from start to finish.

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.
