TrailSense: Crowdsensing Risky Mountain Trail Segments

摘要

Mountain trail surface information is critical to prevent mountain accidents,such as falls.This article presents TrailSensey a mobile crowdsensing system that can automatically label risky mountain trail segments.TrailSense analyzes walking patterns of an individual hiker using smartphone sensing.The results from multiple hikers are then aggregated in the cloud for accurate labeling.Our results from two real-world datasets show that TrailSense can identify,fairly accurately,risky trail segments with crowdsensing.
