Automatic calling before arrival
The system detects guardian approach and starts preparing the student before the car reaches the gate.
Automated school calling to save time and reduce congestion
WOSL makes student pickup faster, safer, and better organized
The system tracks guardian approach automatically and triggers the call before arrival, so students are ready at the gate with less waiting, lower congestion, and smoother pickup operations.

The system's core goals
Designed to solve the most critical school-dismissal challenges: faster calling, less congestion, and safer, more organized pickup.
Save time and reduce congestion
Reduce manual waiting and gate bottlenecks by organizing calls based on real approach and estimated arrival time.
Safer, better-organized pickup
Give the school clearer pickup visibility and reduce chaos at dismissal with real-time call tracking.
GPS-linked smart calling
Automatic tracking (e.g., every 30 seconds) and smart calling when approaching within the geofence so the student is ready at the gate.
- Configurable geofence range (100m to 5000m)
- Arrival-time estimation (4–15 minutes) to manage preparation
- Audit logs for calling and tracking actions
