Traffic Control System Using Periodic Radio Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle location registration systems rely on permanent cellular subscriptions, which are costly and invasive, and lack efficient methods for selectively and temporarily logging vehicle locations without compromising privacy.
Innovation Solution
A system utilizing radio signals and GPS technology, with electronic units in vehicles and intersections, allows for selective and temporary logging of vehicle locations using radio frequency transceivers and cellular network circuit boards, enabling remote control of vehicle functions without continuous network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent cellular subscriptions are used for vehicle location registration, then continuous network connection and tracking capability are improved, but cost and privacy invasion increase
Solution Approach 1:
The system uses periodic radio signal transmissions between vehicles and roadside units to update location information only when necessary, rather than maintaining continuous cellular connection. The GPS receiver and radio transceiver work in periodic cycles to log location data locally, reducing network dependency while maintaining tracking reliability for traffic control purposes
Solution Approach 2:
The patent introduces roadside units with radio frequency transceivers as intermediaries between vehicles and the central traffic control system. These intermediaries collect and cache location data locally using GPS and radio communications, then transmit aggregated information to the server, reducing the need for direct continuous cellular connections from each vehicle
2Object-affected harmful factors
If selective and temporary logging is implemented, then privacy protection and cost reduction are improved, but location tracking capability may be reduced
Solution Approach 1:
The system implements different logging strategies for different locations and time periods. Roadside units store location data locally in their memory for temporary caching, while the central server maintains selective long-term logs based on traffic control needs. This local quality approach allows temporary comprehensive logging near intersections while maintaining privacy elsewhere
Solution Approach 2:
The system dynamically changes logging parameters such as data retention period, transmission frequency, and detail level based on location, time of day, and traffic conditions. The server can adjust whether to log full trajectory data or only aggregated statistics, balancing tracking reliability with privacy protection through parameter modification
3Adaptability or versatility
If radio frequency transceivers and GPS technology are used, then selective logging capability is improved, but device complexity increases
Solution Approach 1:
The electronic units in vehicles and roadside locations are designed as multi-functional devices that perform GPS reception, radio frequency transmission, local data storage, and communication with the central server all within a single integrated unit. This universality reduces the need for separate specialized devices while maintaining selective logging capability through software configuration
