In today’s fast-evolving transportation ecosystem, public agencies are under increasing pressure to do more with less. They need actionable insights to improve traffic flow, evaluate signal timing, and justify funding decisions—but often lack the tools or resources to collect the data themselves. At the same time, platform providers, OEMs, and analytics solution vendors are looking for ways to increase the value of their offerings and better serve these evolving customer needs.
That’s where the INRIX Signal Analytics API comes in: a flexible, scalable way to bring high-quality, standardized signal performance metrics directly into existing tools and workflows.
Why We Built the Signal Analytics API
Many agencies and solution providers already rely on robust platforms for signal control and performance monitoring. But not every user wants (or needs) another dashboard. What they do want is access to trusted, standardized data that can plug directly into their existing systems.
The Signal Analytics API was purpose-built to serve that need—unlocking network-wide signal KPIs like delay, Level of Service (LOS), and percent on green, all derived from anonymized connected vehicle data. No new hardware. No standalone platform to learn. Just powerful metrics that can be integrated into planning tools, analytics environments, or dashboards that agencies already use.
For equipment makers and software providers, this opens the door to a powerful new channel: by embedding INRIX data into their own solutions, they can meet more customer needs—faster—and drive growth without having to go direct.
Expanding Value, Not Replacing It
Our Signal Analytics API is designed to enhance, not replace, existing offerings. Signal vendors, OEMs, and software providers already offer tools that transportation professionals rely on every day. The API adds a layer of insight that complements these solutions—helping partners provide even more value to their customers. It’s easy to integrate, backed by consistent documentation, and supported by INRIX’s two decades of experience in transforming connected vehicle data into actionable intelligence.
By integrating the Signal Analytics API, platform providers can:
- Fill in data gaps for unequipped intersections using connected vehicle insights
- Help agencies evaluate network-wide signal performance without new sensors
- Support grant reporting, planning, and optimization workflows with standardized metrics
- Expand their offering with new subscription-based analytics capabilities
- Differentiate their platform as a one-stop-shop for advanced transportation intelligence
Key features include:
- Instant access to key metrics like delay, throughput, LOS, and percent on green
- Segment-level granularity across a city, corridor, or region
- Support for before/after studies and policy evaluation
- No hardware required—only connected vehicle data
- Stable segment IDs and clean JSON responses for seamless integration
This means less development time, faster deployment, and more value for end users.
In short, the API empowers partners to do more for their customers while building on the capabilities they already provide.
Unlock New Opportunities for Growth
With the Signal Analytics API, OEMs and solution providers can:
- Enter new markets faster without installing hardware
- Support agency reporting and funding requirements
- Enable next-gen analytics on corridors beyond their physical sensor footprint
- Increase the stickiness of their own platforms by embedding valuable new data streams
Most importantly, they can do all of this while supporting public sector goals to make transportation smarter, safer, and more efficient—without users having to adopt a new system.
Let’s Build More, Together
At INRIX, we believe transportation works best when we work together. The Signal Analytics API offers a meaningful way to add value for agencies, streamline integration for partners, and accelerate shared progress in traffic signal optimization.
If you’re a platform provider, hardware vendor, or OEM looking to expand your offering and better serve your customers—we’d love to connect.
