Geofences that tell you something useful

The useful takeaway

Define the question first, then draw the boundary and choose the vehicles, schedule and alerts that answer it.

Give each boundary a job

A geofence is a virtual boundary around a place. It can help the office understand an arrival, departure or time spent on site. Start with an operational question: has a vehicle reached the depot, how long was it at a customer, or did equipment move outside its expected area?

Name the boundary clearly and decide who needs the information. An alert is useful when someone knows what to do next. Sending every crossing to everyone soon makes important events harder to notice.

Draw for the real site

A circle is quick to configure, while a polygon can follow an irregular depot or yard more closely. Consider access roads and nearby public roads when setting the edge. A boundary cutting across a busy road may report visits that were simply vehicles passing by.

GPS accuracy, reporting frequency and device connectivity can affect when a crossing is observed. Test the boundary with real journeys before relying on it for a customer-facing process. A recorded crossing is evidence of a reported position, not proof that a delivery was completed.

Choose the event and the audience

GTrak supports circular and polygon zones with entry and exit alert settings, schedules and device targeting. Use those controls to keep the workflow focused on the vehicles and times that matter. Review the first few days with the team and adjust boundaries that create noise.

Site-visit and time-in-zone reporting can support a more measured review than an immediate alert. For example, a weekly dwell-time review may reveal a queueing issue that individual arrival notifications would never explain.
