Accident Information Server Using Nearby Vehicle and Phone Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems fail to effectively utilize image and sound data from vehicles in uncommunicable states during multi-vehicle accidents, leading to incomplete information transmission to emergency centers.
Innovation Solution
A server apparatus that communicates with peripheral vehicles and portable devices to determine the presence of vehicles without emergency notification systems, acquires position data, requests information from a set target area, collects accident information, and extracts relevant data to notify an emergency center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing vehicle notification systems are used, then emergency notification can be sent, but information from vehicles without emergency notification systems cannot be collected
Solution Approach 1:
A server apparatus acts as an intermediary between vehicles with emergency notification systems and the emergency center. The server receives image data from peripheral vehicles, determines presence of vehicles without emergency notification systems, and collects information from portable devices in the target area to compensate for missing data, thereby enabling comprehensive information collection despite vehicle compatibility differences
Solution Approach 2:
The system is designed to work with multiple types of vehicles regardless of whether they have emergency notification systems. By using image data from peripheral vehicles and expanding the collection target to include portable devices in a broader target area, the system achieves universal information collection capability across different vehicle types and configurations
2Reliability
If information is collected only from vehicles with emergency notification systems, then communication reliability is maintained, but information completeness deteriorates
Solution Approach 1:
The system expands the information collection dimension from only vehicles with emergency notification systems to include portable devices in a broader target area. By determining the presence of vehicles without emergency notification systems through image data and expanding the collection scope accordingly, the system recovers information that would otherwise be lost while maintaining overall system reliability
3Productivity
If the collection target area is limited to peripheral area, then communication efficiency is maintained, but information completeness deteriorates
Solution Approach 1:
The system dynamically adjusts the information collection strategy based on detected conditions. When vehicles without emergency notification systems are detected through image data analysis, the system expands the collection target area from the immediate peripheral area to a broader target area, enabling flexible adaptation to maintain information completeness while managing communication efficiency
Data Source
AI summary
A server apparatus determines whether a vehicle without an emergency notification system is included in accident vehicles based on image data received from peripheral vehicles or peripheral portable devices. When the vehicle without the emergency notification system is included, the server acquires position data on a vehicle having issued an emergency notification. The server requests a base station covering the acquired position to send an information provision request to vehicles and portable devices present in a set target area. The server collects accident information from the peripheral vehicles and the peripheral portable devices, and collects information from the vehicles and the portable devices present in the set target area. The extractor extracts accident information from the information collected from the vehicles or the portable devices present in the set target area based on the position data. The server notifies an emergency notification center of the accident information collected or extracted.
