Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS information and vehicle speeds are collected from vehicles to generate traffic information, then traffic information accuracy is improved, but the system cannot collect data from vehicles without GPS or communication devices
Solution Approach 1:
The patent introduces relay vehicles equipped with detection sensors as intermediaries to collect information from surrounding vehicles that lack GPS or communication devices. The relay vehicle detects surrounding vehicles' positions, speeds, and license plates, then transmits this data to the server, enabling traffic information collection from vehicles without direct communication capabilities.
Solution Approach 2:
The patent replaces the electronic communication-based data collection system (GPS and communication devices in vehicles) with a sensor-based detection system on relay vehicles. The detection sensors optically or electromagnetically detect vehicle information, converting it into transmittable data for the server, thus substituting direct mechanical/electronic vehicle systems with an external detection mechanism.
2Quantity of substance
If mobile device information is used to generate traffic information, then data coverage is improved, but personal information is collected which conflicts with institutional regulations
Solution Approach 1:
The patent extracts only the necessary traffic-relevant information (position, speed, license plate) from the detected vehicle data while excluding personal information. The server processes this extracted data to generate traffic information without storing or utilizing personal identifiers beyond what is necessary for vehicle identification, thus separating useful traffic data from sensitive personal information.
Solution Approach 2:
The patent uses license plate information as a non-intrusive copy or identifier of vehicle identity that does not reveal personal information. Instead of accessing mobile device data containing personal information, the system creates a traffic information model based on copied visual data from license plates and detection sensors, maintaining data coverage while avoiding personal information collection.
3Measurement precision
If data from a larger number of vehicles is collected to determine traffic information more accurately, then traffic information accuracy is improved, but duplicate vehicles cause data redundancy
Solution Approach 1:
The patent implements a feedback mechanism where the server receives detection results from relay vehicles, identifies duplicate vehicles based on license plate information and position data, and filters out redundant entries. This feedback loop ensures that traffic information is generated from unique vehicle data, maintaining data quality while processing large volumes of detection data.
Solution Approach 2:
The patent changes the identification parameter from simple vehicle detection to multi-parameter verification including license plate recognition, position coordinates, and speed data. By using multiple parameters to identify vehicles, the system can distinguish between different vehicles more accurately and eliminate duplicates, thereby improving data quality while processing large datasets.
Data Source
AI summary
An apparatus and a method are configured to generate traffic information based on vehicles that may or may not include GPS or communication devices. The apparatus for generating traffic information includes a memory that stores instructions for traffic information generation, and a processor that executes the instructions. The processor may determine a traveling vehicle by excluding duplicate vehicles from surrounding vehicles based on location information of relay vehicles traveling on a road and vehicle information of the surrounding vehicles, the surrounding vehicles being detected by the relay vehicles, and generate the traffic information based on traveling information of the traveling vehicle.
