Geofence arrival and departure detection

How the 1-mile stop geofence and the 10-minute arrival dwell let a load mark itself arrived and departed on its own.

4 min read

Numeo One draws a circle around every stop and watches the truck cross it. That's how a load marks itself arrived and departed without you calling the driver to ask.

The stop geofence

Every stop on a load gets a geofence — a 1-mile radius around the stop location. Numeo compares the truck's live position to that circle continuously and reacts as the truck crosses in and out.

The three detection events

Numeo watches for three things at each stop:

  • Nearby Stop Detection — fires the moment the truck first crosses into the geofence. It's your heads-up that the truck is close.
  • Arrival Detection — fires after the truck has stayed inside the geofence for at least 10 minutes.
  • Departure Detection — fires once the truck leaves the geofence.

Why arrival waits 10 minutes

The 10-minute dwell filters out a truck that's just passing by or caught at a light near the stop. Making the truck settle for a few minutes means "Arrived" actually means arrived, not "drove past."

On the load, a "Geofence" countdown shows how long the truck has been sitting inside the stop before arrival is confirmed — so you can watch it count down.

How the status changes

As the truck crosses these boundaries, the load's status moves through En Route → Arrived → Completed. Numeo can set those from the geofence automatically, on a schedule, or you can set one by hand — and every change records which way it happened. For the full breakdown, see Load statuses explained.

Turn detections into alerts

Each of these events can also notify the people who need to know — your team, the driver, or the broker. Arrival, nearby-stop, and departure alerts are part of the notification catalog. See Driver notifications over Telegram.

Good to know

  • ETA reacts to the geofence too: as the truck nears the 1-mile boundary, Numeo re-tightens the ETA so the number stays honest. See Live tracking, ETA, and geofences.
  • Detection runs in the background on every load — you don't arm or refresh anything per stop.
