Autonomous multi-station avalanche detection system based on long-range radar technology for road safety at Bear Pass, BC
The real-time avalanche detection system on Highway 37A was tailored to the remote location and harsh environmental conditions at Bear Pass and consists of two long-range avalanche radar stations and a radio link station for independent data transmission. The system is designed for autonomous operation of more than 6 months without on-site intervention and includes automatic event mapping with high-resolution images and event notification. In the first season, the system detected more than 1200 events and assisted the avalanche team to reduce avalanche-related road closures by more than 40%.
