Mobile Terminal Evacuation Routing and Safety Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for safety confirmation during natural disasters often prioritize personal safety over evacuation, leading to the expansion of damage due to delayed evacuation efforts.
Innovation Solution
A call-to-action system that utilizes mobile terminal devices to collect and provide safety confirmation information while urging evacuation by identifying and analyzing the actions of initiative actors, including displaying evacuation routes and transmitting start information to pre-registered destinations, and analyzing migration data to identify initiative actors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system prioritizes safety confirmation information collection, then safety verification is improved, but evacuation speed deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-registering delivery destinations and evacuation routes before disasters occur. During disasters, the mobile terminal automatically transmits action start information to pre-registered destinations without requiring user input, eliminating the time-consuming decision-making process and prioritizing immediate evacuation while maintaining safety confirmation capabilities
Solution Approach 2:
The system implements feedback mechanisms by analyzing migration information from multiple mobile terminals to identify initiative actors. The system provides feedback to other users by displaying information about initiative actors who have started evacuation, creating a social influence effect that accelerates evacuation speed while maintaining comprehensive safety confirmation through continuous information collection
2Reliability
If the system encourages individual safety confirmation, then personal safety verification is improved, but damage expansion worsens
Solution Approach 1:
The system inverts the traditional safety confirmation approach by not directly confirming individual safety status. Instead, it identifies initiative actors through migration pattern analysis and uses their actions as indirect safety indicators. This inversion allows the system to maintain personal safety verification capabilities while preventing damage expansion through accelerated collective evacuation behavior
Solution Approach 2:
The system introduces initiative actors as intermediaries between individual safety confirmation and collective evacuation. By displaying information about initiative actors to other users, the system creates a social mediation effect that encourages others to evacuate without requiring direct safety confirmation from each individual, thus preventing damage expansion while maintaining safety verification
3Measurement precision
If the system analyzes migration information from all terminals, then initiative actor identification is improved, but system complexity worsens
Solution Approach 1:
The system applies partial action by focusing analysis on specific migration patterns rather than processing all possible data from every terminal comprehensively. The action analysis unit identifies initiative actors by analyzing key parameters such as evacuation timing and route selection, achieving sufficient identification precision without the need for exhaustive analysis of all migration information, thus maintaining manageable system complexity

AI summary
Provided are a mobile terminal device and a safety confirmation system that can collect and provide information for safety confirmation while urging evacuation. The device is provided with: a current location acquisition unit (32) that acquires a current location when disaster occurrence information (30) has been received; a route display control unit (33) that displays a route that leads from the acquired current location to a pre-registered evacuation site; a start display control unit (34) that displays a start entry screen for entering an input that evacuation has started; and an action start information transmission unit (35) that transmits, when evacuation start information indicating that evacuation has started is entered from the start entry screen by an operation of a user, the evacuation start information to a pre-registered destination.
