API Reference
The Traffic Overview API provides a real-time snapshot of traffic conditions on Dutch roads. It includes congestion reports, road closures, and traffic measures, aggregated into a single feed. The API is updated every few minutes and designed for building traffic dashboards, travel apps, and mobility solutions.
No parameters needed.
