The product allows agencies to integrate real-time and historical data directly into existing operational systems — including advanced traffic management system (ATMS) platforms, traffic management centre (TMC) tools, analytics environments, and custom applications — without manual data exports.
Flow API comprises two components:
Signals APIs — providing real-time and historical signal performance measures, covering metrics for performance monitoring, automated reporting, and integration of signal intelligence into operational systems
Segments APIs — providing real-time and historical mobility data to support live operations monitoring, performance benchmarking, corridor analysis, and planning workflows
The launch is framed around interoperability. Transportation agencies typically draw data from multiple sources — controllers, detectors, connected vehicles, geographic information systems (GIS), and third-party platforms — and Flow Labs says the API is designed to work alongside existing infrastructure rather than in isolation from it.

“Transportation agencies invest significantly in their data infrastructure and deserve to get full value from it,” says Jatish Patel, chief executive officer at Flow Labs. “Too much of this industry has been built around closed systems and vendor lock-in, keeping agencies dependent on proprietary workflows rather than empowering them to use their data on their own terms. Flow API is our answer to that — open, accessible, and built to integrate with the systems agencies already run.”
Flow API is available to agency customers now, with the platform set to expand as new datasets and capabilities are added.
