For many transportation professionals striving to understand systemwide performance, the biggest challenge isn’t a lack of data—it’s that insights are trapped in too many places.
Over the past decade, signal performance measurement has made significant strides thanks to ATSPMs and high-resolution controller data. But for many cities and vendors, the path to full network visibility remains blocked by three major obstacles:
- Limited Visibility: Most solutions rely on field-based detection. If you don’t have a loop or radar at the intersection, you don’t get data. That means critical blind spots—especially in underserved or high-priority corridors.
- Prohibitive Costs: Deploying ATSPM infrastructure citywide takes years and millions in funding. Even vendors can’t demonstrate value until hardware is installed and calibrated.
- Siloed Systems and Inconsistent Data: Even when agencies or vendors have access to traffic signal data, it often lives in disconnected systems—each with its own format, granularity, and limitations. Field sensors produce high-resolution data, but only locally. Consultant studies use short-term samples. Vendor dashboards are black boxes with limited export options.
Some agencies are also overwhelmed by too many dashboards—each offering limited visibility, inconsistent metrics, and locked-in workflows. Instead of simplifying decisions, these fragmented tools create more work, forcing teams to cross-reference platforms and navigate conflicting data.
The result? Widespread dashboard fatigue and growing demand for unified, flexible solutions.
The Solution: INRIX Signal Analytics Networkwide Insights Delivered via API
To help public agencies and signal hardware vendors overcome these challenges, INRIX has launched a new Signal Analytics API. This powerful solution delivers high-frequency, anonymized connected vehicle data—processed into movement-level signal performance metrics—at more than 300,000 signalized intersections nationwide.
Now, you can access:
- Control Delay (seconds/vehicle)
- Level of Service (LOS)
- Percent Arrival on Green (POG)
- Turn Movement Percentages
- 3-Minute Delay Counts
- And more!
And you can access this data via secure API, directly into your existing tools—without relying on additional dashboards or deploying new hardware.
Why This Matters
The Signal Analytics API delivers value to both public agencies and infrastructure vendors by enabling:
For Public Agencies:
- Systemwide Coverage: Get metrics at every signalized intersection, not just where sensors are installed.
- Bring-Your-Own Dashboard: Integrate data into tools you already use (GIS platforms, BI tools, or internal dashboards).
- Equity and Compliance Insights: Measure performance in underserved areas and meet grant or regulatory requirements.
- Lower Cost, Faster Results: Avoid the delays and expense of field installs or time-intensive traffic studies.
For Vendors and OEMs:
- Analytics at Every Intersection: Expand your platform’s value even before hardware is installed.
- Faster Time-to-Insight: Provide immediate metrics on Day 1, during pilot phases, or while waiting on permits.
- New Revenue Opportunities: Introduce software-driven subscriptions and “networkwide analytics” upsells.
- Enhanced Product Offerings: Blend hardware data with INRIX metrics for a truly hybrid “hardware + software” solution.
How It Works
The API is built on INRIX’s advanced data platform and processes high-frequency CV probe data. Metrics are made available via secure endpoints with flexible filters for location, date, time of day, and movement type. Responses are returned in compact JSON format—perfect for ingesting into dashboards, GIS systems, or traffic operations platforms.
With 15-minute granularity and support for both current and historical analysis, this is a turnkey solution for organizations looking to scale up without scaling infrastructure.
