警报和警告的目的是向公众提供必要的信息，以确保他们在紧急情况下的安全。随着智能手机的广泛使用，国家的警报能力需要发展和进步，更新的技术也可以使用，特别是要更精确地针对处于危险中的亚人群。从历史上看，这一直是一个挑战，因为向公众传递警报和警告信息主要是通过广播媒体和标志。然而，部署这些标志需要时间，而且可能无法被即将发生自然灾害的人看到。特别是用于道路封闭、标记危险、紧急疏散等，具有不需要视线的易于部署和自动化的警报/警告系统将是有益的。为此，我们开发了Insight -一种基于蓝牙信标的系统，该系统使用智能手机应用程序来感知标记危险区域的信标信号。该系统不需要任何互联网或通信基础设施，因此，它对灾害期间的通信中断具有复原力。为了证明Insight的可行性，我们在一个城市大学校园进行了一项研究。该系统证明了足够的可用性和可行性。
The purpose of alerts and warnings is to provide necessary information to the public that will lead to their safety in emergencies. The nation's alerting capabilities need to evolve and progress with the extensive use of smartphones, and newer technologies become available, especially to be more precisely targeted to sub-populations at risk. Historically, this has been a challenge as the delivery of alerts and warning messages to the public is primarily through broadcast media and signs. However, deploying such signs takes time and may not be visible to people imminent of natural hazards. Especially for road closing, marking hazards, emergency evacuation, etc., it would be beneficial to have an easy-to-deploy and automated alert/warning system that requires no line of sight. To this end, we have developed Insight - a Bluetooth beacon-based system that uses a smartphone application to sense signals from beacons marking hazard zones. The system does not require any Internet or communication infrastructure and therefore, it is resilient to breakdowns in communications during disasters. To demonstrate the feasibility of Insight, we conducted a study in an urban university campus location. The system demonstrated adequate usability and feasibility.
