For transportation agencies, every decision starts with data. That data comes from a myriad of different sources - detection devices, signal controllers, connected vehicles, GIS, spreadsheets and reports - but too often, it remains stuck where it is. Closed standards, vendor lock-in, and incompatible formats mean agencies end up fighting their own infrastructure just to access data they already paid for.

Today, we’re launching Flow API to make it easier than ever for agencies to get access to the data they need, wherever they need it. Flow API gives transportation agencies and our platform users a simple, accessible way to use the same trusted data they already rely on so that it can be integrated directly into the systems that need it most.

From Many to One, From One to All

From the very beginning the Flow Platform has been designed with openness in mind. We started by making sure that agencies could get all of their data in one place - we integrated data from every source available creating a unified, comprehensive picture of what is happening on any given roadway or signal at any given time. 

Flow API extends that openness by making it easier to connect data from the Flow Platform to the rest of an agency’s technology ecosystem. Instead of forcing agencies into a closed workflow, Flow API supports flexible integration - so that data can flow in from many sources and Flow’s insights can flow out to wherever teams need them.

Designed to Be Simple and Accessible

APIs don’t have to be complicated to be powerful. Flow API is intentionally designed for real-world transportation teams, not just software developers. Clear documentation, straightforward endpoints, and flexible queries make it easy to get started—whether you’re integrating with an ATMS, building dashboards, or automating reports.

We firmly believe that the easier our data is to consume, the more it can be used, and the more impact it will have.

Every Signal, Every Segment, Historical, and Real-Time

Flow API is a comprehensive suite of APIs covering the full range of data transportation agencies need — signal performance and mobility, real-time and historical.

Transportation decisions depend on both what's happening now and what's happened over time. Real-time data supports live monitoring and operational response. Historical data supports analysis, reporting, and performance evaluation. Flow API provides both, from the same consistent source that powers the Flow platform.

Segments APIs cover mobility and corridor performance. Use them for:

• Real-time monitoring of live traffic conditions and operations
• Historical analysis, reporting, and performance benchmarking
• Planning and before-and-after evaluation of corridor changes

Signals APIs provide access to the most complex and operationally critical data type agencies manage. Use them to:

• Monitor signal performance proactively
• Automate signal performance reporting
• Integrate signal data into operational and analytics systems

Whatever the use case, the data is there.

Proven at Scale and Built to Grow

Flow API builds on Flow Labs’ experience supporting large-scale deployments with transportation agencies, including work with the Florida Department of Transportation. These real-world deployments informed how Flow API was designed—prioritizing reliability, clarity, and ease of use at scale.

Flow API is designed to evolve alongside agency needs. As new datasets and capabilities are added across the Flow platform, Flow API will continue to expand—providing more ways to access, integrate, and apply data over time.

Get Started with Flow API

Flow API makes it easier for agencies to get more from their data without adding complexity. Simple, accessible, and powered by Flow, it’s designed to fit naturally into the tools and workflows transportation teams already use.
