Geo-Fencing

Also known as: Geofencing, Virtual Perimeter, Location-Based Triggers

Definition

Geo-fencing creates invisible virtual boundaries around geographic locations. When a tracked asset (vehicle, container, or package) crosses these boundaries, the system automatically triggers predefined actions like notifications or status updates.

How Geo-Fencing Works

  1. Define boundaries - Draw virtual perimeters around locations
  2. Track assets - GPS devices report location continuously
  3. Detect crossings - System identifies when boundaries are crossed
  4. Trigger actions - Automated responses execute immediately

Common Geo-Fence Triggers

Event Example Action
Truck enters facility Alert receiving team to prepare
Container leaves port Update status to “in transit”
Driver approaches delivery Send customer “arriving soon” text
Asset enters restricted area Security alert
Vehicle deviates from route Dispatch notification

Applications in Shipping

Fleet Management

  • Proof of presence at locations

Asset Tracking

  • Alert when containers leave designated areas
  • Monitor dwell time at facilities
  • Track trailer locations across yards

Benefits

  • Automation - Reduce manual status updates
  • Visibility - Real-time location awareness
  • Accountability - Verify presence at locations
  • Customer experience - Proactive delivery notifications
  • Security - Detect theft or unauthorized movement

Implementation Considerations

  • GPS accuracy varies (typically 3-15 meters)
  • Battery life of tracking devices
  • Cellular coverage in remote areas
  • Privacy concerns for driver tracking
