Route Planning Avoiding Flooded Areas Using Weather Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route planning systems fail to account for flooding during water disasters, making it difficult to navigate safely through flooded areas during events like guerrilla torrential rain.
Innovation Solution
An information processing apparatus and method that acquire weather and flood prediction information to propose a route avoiding potential flood points, using a processor to determine and output a safe route from a departure point to a destination, considering current and future flooding conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional route planning system is used, then the route can be calculated quickly and simply, but the route may pass through flooded areas during water disasters
Solution Approach 1:
The system performs preliminary actions by acquiring flood prediction information and identifying potential flood points before calculating the route. The processor acquires weather information and flood prediction data, identifies points likely to be flooded, and then calculates a route that avoids these points in advance, ensuring route safety before the user travels
Solution Approach 2:
The system segments the route planning process into distinct stages: acquiring weather information, acquiring flood prediction information, identifying potential flood points, and calculating the safe route. This segmentation allows the system to integrate flood avoidance functionality without completely redesigning the entire route planning system
2Reliability
If flood prediction information is integrated into route planning, then route safety during water disasters is improved, but information processing requirements increase
Solution Approach 1:
The system extracts only the essential flood prediction information needed for route planning - specifically identifying points with lower altitude that may be flooded. Rather than processing all available flood data, the system extracts and uses only the critical information about potential flood points along the route path
Solution Approach 2:
The system acquires and processes flood prediction information in advance before route calculation. By performing this information processing preliminarily, the system prepares flood avoidance data that can be quickly integrated into route planning without adding significant processing load during the actual route calculation phase

AI summary
An information processing apparatus includes a processor configured to acquire, for a first area including a range from a departure point to a destination, first information related to weather and second information related to a point having lower altitude above sea level than a surrounding area, and acquire, based on the first information and the second information on the first area, a first route that is a route from the departure point to the destination and that avoids a point that may be flooded in the event of a water disaster, and output the first route. The processor acquires the first route for each of the one or more future time points from the departure time.
