Traffic congestion doesn’t just waste time—it costs cities millions in lost productivity, fuel, and environmental impacts.
Traditionally, managing traffic signals meant costly field equipment, tedious data collection, and reactive analysis. But what if agencies could gain systemwide signal insights—24/7, at every intersection—without deploying or maintaining a single piece of new hardware?
That’s what INRIX Signal Analytics, powered by CATT Lab, delivers. Already trusted by more than 100 U.S. municipalities, the platform helps agencies proactively manage signals, streamline retiming, and prioritize corridor improvements faster, better, and cheaper.
Always-On, Anonymous Data from the Road Itself
INRIX data is sourced anonymously from automakers, providing cities with a continuous stream of “floating cars” traveling through every intersection and arterial, 24 hours a day, 7 days a week. This always-on coverage delivers:
- Continuous systemwide visibility – Every movement, at every intersection, on every arterial.
- Proactive problem detection – Spot issues as they happen.
- Trusted accuracy – Industry-standard calculations ensure fair and reliable comparisons.
A Storytelling Platform for City Leaders
Managing traffic isn’t just about adjusting signals, it’s about demonstrating impact. Signal Analytics makes it simple to tell the story of your investments:
- Show how retiming efforts reduce delays and improve reliability.
- Demonstrate environmental and emissions benefits.
- Clearly illustrate the value of arterial and intersection treatments.
- Share performance improvements with stakeholders and the public.
And critically, agencies can use the platform to measure and evaluate intersection and corridor performance after significant retiming efforts—without deploying any additional hardware. This makes it easier than ever to prove the real-world benefits of timing changes and justify future investments.

What Agencies Can Measure with INRIX
Using industry-standard methodologies, Signal Analytics directly measures:
- Delays and stops (arrivals on red/green)
- Excessive delay events (split failures)
- Travel speeds
- Travel time and reliability
- Environmental and emissions impacts
These insights allow agencies not only to retime signals effectively, but also to quantify the benefits—from improved travel time reliability to reduced emissions.
