Bus stop displays, connected billboards or road displays, and even displays inside buses and connected cars can help disseminate accurate and timely information to people who are in the affected area. Messages can also be tailored according the demographics of the user of the particular device, such as adding new languages, specific instructions, routing, and video feeds of nearby areas to help them best protect themselves when disaster strikes. Smart Sensors
