Cloud Evacuation Guidance System Dynamic Route Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mass evacuation systems are inadequate in providing personalized, real-time guidance to individuals during emergencies, often leading to panic and inefficiency due to lack of integration with GPS devices and social media information, and may fail to account for dynamic changes in hazard areas or reach individuals in need, such as those in hospitals or nursing homes.
Innovation Solution
A cloud-based evacuation guidance system that uses portable devices to provide real-time GPS maps and dynamically updates evacuation routes based on MNS alerts, social media data, and user location, offering personalized guidance and rerouting around hazards, even in cases of network congestion, and includes features for monitoring and assisting special evacuees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional mass evacuation systems use sirens, radio, or telephone dialing systems to notify residents, then the system can provide emergency notification to the public, but the system cannot provide personalized, real-time guidance to individuals during emergencies
Solution Approach 1:
The system segments the evacuation guidance process by providing individualized directions to each user's portable device based on their specific location and destination, rather than providing general public announcements. This segmentation enables personalized real-time guidance while maintaining system manageability through modular architecture.
Solution Approach 2:
The patent introduces a server as an intermediary between the emergency notification system and individual users' portable devices. The server receives hazard information, determines user locations, calculates evacuation routes, and sends personalized directions, thereby bridging the gap between mass notification systems and individual guidance needs.
2Adaptability or versatility
If the system provides static evacuation plans, then the system can offer pre-established evacuation routes, but the system cannot account for dynamic changes in hazard areas or environmental conditions
Solution Approach 1:
The system implements dynamic evacuation routing by continuously monitoring hazard information and environmental conditions, then recalculating and updating evacuation routes in real-time based on changing conditions. This dynamic approach allows the system to adapt to evolving situations while providing timely updates to users.
Solution Approach 2:
The system incorporates feedback mechanisms by receiving real-time hazard information from multiple sources, monitoring the status of evacuation routes, and using this feedback to continuously update and optimize evacuation directions sent to users' portable devices.
3Ease of operation
If the system uses general public notification methods, then the system can reach a broad audience, but the system cannot reach or provide personalized assistance to individuals with special needs, such as those in hospitals or nursing homes
Solution Approach 1:
The system applies local quality by providing customized evacuation information tailored to each user's specific situation, location, and needs. Users with special needs receive personalized directions and assistance appropriate to their circumstances, rather than receiving generic public notifications.
Solution Approach 2:
The system achieves universality by designing a portable device-based solution that can serve diverse user populations including individuals with special needs, elderly persons, and able-bodied residents. The system accommodates various evacuation scenarios and user capabilities through its flexible, personalized approach.
4Measurement precision
If the system integrates real-time GPS tracking and social media monitoring, then the system can provide accurate real-time evacuation guidance, but the system increases complexity in data processing and route dynamic updates
Solution Approach 1:
The system implements self-service by automatically collecting GPS location data from users' portable devices and autonomously processing this information to determine user positions, calculate routes, and provide guidance without requiring manual intervention or complex centralized tracking infrastructure.
Solution Approach 2:
The system uses copying by leveraging existing data infrastructure and social media platforms rather than building entirely new data collection systems. It retrieves and processes hazard information from existing social media sources and public safety organization websites, reducing the complexity of original data collection.

AI summary
A system including is provided that includes a cloud application executing on a cloud processor that detects an evacuation message, a portable device that receives a notification from the cloud application of the evacuation message, a processor of the cloud application that determines a current geographic location of the portable device and an evacuation destination for the portable device and that downloads a map to the portable device showing a route from the current location to the evacuation destination, and a processor that updates the map based upon real-time events occurring along the route.
