Capture a probe drive from your phone.
This page streams GPS + accelerometer data at 1 Hz to /ingest.
The server accumulates data across road links until 1 km is reached,
extracts features, predicts density, and registers the result with the
multi-probe ensemble. Road info (speed limit, lanes) is auto-detected from GIS link matching.
Start collection after confirming HTTPS, motion permission, GPS lock, and live server connectivity.
