Across the U.S., most traffic signals aren't actively monitored. Outdated timing plans lead to unnecessary congestion, wasted fuel, and frustrated drivers. From monitoring to diagnostics to optimization, Flow Labs provides products to manage signals end-to-end. Each product supports a key part of the workflow—and together, they deliver a smarter, faster, more affordable way to improve signal performance across your network. The Flow Platform goes beyond showing you data — it helps you get real work done, faster and smarter.
Flow Labs helps transportation agencies monitor, analyze, and improve traffic signal operations using connected vehicle data and advanced analytics. By bringing key signal management tools into one platform, Flow Labs makes it easier to identify problems, measure performance, and make better decisions across an entire traffic signal network.
Traffic signals are difficult to monitor at scale - manual fieldwork, disconnected systems, and limited visibility slow down decision-making. Luminus solves this by turning connected vehicle data into instant signal performance metrics, with no new hardware, no controller integration, and no detection systems needed.
With just a few clicks, agencies gain real-time, high-accuracy insights into traffic signal performance—across entire networks. Luminus enables engineers to proactively monitor signals, analyze timing plans, and generate before-after reports in seconds. By eliminating field installs and using anonymized probe data from 16-32% of vehicles on the road, Luminus unlocks affordable, scalable, and accurate signal operations for modern agencies.
Luminus Plus is the industry's first truly integrated signal performance platform. By unifying infrastructure-based data from ATSPMs with high-penetration probe vehicle data, Luminus Plus gives agencies unmatched clarity into how signals are working and how to improve them. No more switching tools, reconciling sources, or guessing between datasets. Just one platform, total insight.
The platform integrates signal controller logs, detection events, and real-time vehicle trajectory data, so engineers can see how traffic is actually moving through each intersection and corridor. Whether you're reviewing arrivals on green, coordination quality, or phase utilization, all the data is in one place and aligned on a shared timeline.
