Vehicle Disaster Evacuation Assistance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for providing assistance to vehicle users during disasters are inadequate, as they do not effectively address the specific needs and inconveniences of users who spend nights in vehicles, such as privacy concerns and lack of suitable assistance.
Innovation Solution
An information processing device communicates with vehicles to identify those in disaster areas, sends messages to users to determine if they need assistance, and if they agree to share personal information with organizations that can provide help, thereby selecting and notifying the appropriate organization for assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional safety confirmation methods are used, then basic safety information can be transmitted, but specific needs of users spending nights in vehicles (privacy, comfort, assistance) are not addressed
Solution Approach 1:
The assistance system segments the disaster response process into distinct phases: initial safety confirmation, evacuation spot identification, and targeted assistance provision. Each phase uses customized message templates addressing specific user needs (privacy, comfort, supplies) rather than generic communications, enabling adaptable assistance while maintaining manageable system complexity through structured segmentation
Solution Approach 2:
The message communication system dynamically adapts its content and focus based on the user's situation. The system transitions from general safety queries to specific evacuation spot confirmation, then to targeted assistance requests based on real-time user responses. This dynamic messaging approach enables versatility in addressing different user needs while keeping the communication framework flexible rather than rigid
2Measurement precision
If multiple messages are sent to determine user needs, then accurate identification of assistance requirements is achieved, but communication time and user burden increase
Solution Approach 1:
The system performs preliminary actions by sending structured message sequences that progressively gather necessary information. Instead of asking all questions at once, the system first confirms basic safety status, then identifies evacuation spot needs, and finally determines specific assistance requirements. This preliminary, staged approach achieves precise user need identification while reducing overall communication time compared to sending all questions simultaneously or through multiple separate interactions
Solution Approach 2:
The system implements feedback mechanisms where each user response informs the content and focus of subsequent messages. Based on user answers about safety status and evacuation needs, the system dynamically adjusts follow-up communications to ask only relevant questions. This feedback-driven messaging reduces unnecessary communications and user burden while maintaining high accuracy in identifying assistance requirements
3Ease of operation
If personal information is collected for disaster assistance, then targeted support can be provided, but user privacy concerns increase
Solution Approach 1:
The system uses an intermediary approach by collecting and managing user information through a controlled communication framework rather than direct exposure to assistance providers. The information processing device acts as an intermediary that receives user responses, processes assistance requests, and coordinates with support organizations while protecting user privacy. This intermediary mechanism enables efficient targeted assistance delivery while mitigating privacy concerns through structured information handling
Solution Approach 2:
The system enables users to self-manage their information sharing preferences through the message communication process. Users can indicate their assistance needs and information sharing willingness through structured responses, allowing them to control what personal information is provided and to whom. This self-service approach reduces privacy concerns by empowering users to make informed decisions about their information while still enabling efficient assistance delivery

AI summary
A method that is performed by an information processing device that communicates with a plurality of vehicles includes identifying any vehicle located in a disaster area out of the plurality of vehicles, sending a first message asking a user of the identified vehicle whether the vehicle is being used as an evacuation spot for spending the night, and determining whether the vehicle is being used as the evacuation spot, based on a first response to the first message.
