Trailsense monitors trail traffic without cameras
Trailsense is a privacy-first crowd monitoring system that measures traffic on hiking trails using solar-powered nodes. By detecting anonymous Wi-Fi probe requests from hikers' phones, the camera-free system provides managers with traffic insights without collecting personal data.
Trailsense offers a highly practical, low-impact solution for trail occupancy tracking, though it must contend with the inherent inaccuracies of Wi-Fi probe tracking.
- –Strong privacy posture: The camera-free design is highly appealing for public parks and users concerned with tracking and surveillance.
- –Operational autonomy: Solar-powered nodes are ideal for remote, off-grid trailheads where wiring is unavailable.
- –Inherent statistical noise: Data accuracy could be impacted by hikers who disable Wi-Fi, those who do not carry phones, or individuals carrying multiple connected devices.
