Flood Detection Using Traffic Volume and Meteorological Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flood detection systems require a flood sensor installed on each vehicle, leading to varying determination results based on vehicle type and design restrictions, which complicates achieving consistent accuracy.
Innovation Solution
A flood detection system that uses meteorological data and traffic volume data to determine flooded areas without a vehicle-mounted sensor, utilizing a meteorological data acquisition unit, traffic volume data acquisition unit, and determination unit to identify areas with reduced vehicle traffic during or after rainfall, and applies a vehicle behavior model to improve detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flood sensor is installed on each vehicle to detect flooding, then flood detection capability is achieved, but device complexity increases and determination accuracy varies by vehicle type
Solution Approach 1:
The patent applies universality by using existing vehicle sensors (accelerometer, GPS, barometer) that serve multiple purposes - navigation, stability control, and flood detection - rather than adding dedicated flood sensors. This makes the system universally applicable across different vehicle types without increasing hardware complexity.
Solution Approach 2:
The system uses data already being collected by the vehicle's existing sensors for other functions (acceleration, position, altitude) and repurposes it for flood detection. The vehicle's own operational data serves the dual purpose of normal operation and flood detection, eliminating the need for separate detection hardware.
2Measurement precision
If vehicle-mounted flood sensors are used, then real-time flood detection is possible, but installation requirements vary by vehicle type reducing ease of manufacture
Solution Approach 1:
The patent uses sensor data (accelerometer, GPS, barometer) that is already universally present in modern vehicles for multiple functions including flood detection. This eliminates the need for vehicle-type-specific installations while maintaining detection precision through multi-parameter analysis.
Solution Approach 2:
The patent merges flood detection functionality with existing vehicle sensor systems and navigation software. By combining data from multiple existing sensors and integrating with the vehicle's operational system, it achieves precise flood detection without requiring separate installation procedures for different vehicle types.
3Reliability
If dedicated flood sensors are installed on vehicles, then flood detection accuracy is improved, but the number of components and system complexity increase
Solution Approach 1:
The system repurposes data already being collected by the vehicle's existing sensors for other functions. The accelerometer, GPS, and barometer data used for navigation and vehicle control also serve flood detection, making the system self-sufficient without additional components.
Solution Approach 2:
Existing vehicle sensors are made multi-functional, serving both their original purposes and flood detection. This universal usage of sensors maintains detection reliability while avoiding the complexity increase that would result from adding dedicated flood detection hardware.

AI summary
A flood detection device and method that acquires meteorological data; acquires traffic volume data representing vehicle traffic volume; and determines that an area, in which a vehicle traffic volume during or after rain is less than or equal to a predetermined number of vehicles, is flooded based on the meteorological data and the traffic volume data, when a probability, that the vehicle traffic volume in a normal time is less than or equal to the predetermined number of vehicles, is less than a predetermined value, the normal time being a state in which a rainfall amount is less than a predetermined value.
