RSU-CCTV Cooperation for Vehicle Driving Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road side units (RSUs) are limited in their ability to cover all areas for driving negotiations, and closed-circuit televisions (CCTVs) cannot participate in driving negotiations due to lack of supported message specifications, hindering smooth and safe vehicle communication.
Innovation Solution
A method and system that enables RSUs to receive temporary identification (ID) messages from CCTVs, allowing CCTVs to participate in driving negotiations by using encryption values of vehicle unique IDs, ensuring privacy protection and enabling continuous negotiations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RSUs are used to perform driving negotiations, then vehicle communication capability is improved, but coverage area is limited
Solution Approach 1:
The patent merges the functionality of RSUs and CCTVs into a cooperative system where RSUs handle message specification processing and CCTVs provide wide-area surveillance coverage. This combination allows the system to maintain advanced communication capabilities while extending the effective coverage area through the CCTV network infrastructure.
Solution Approach 2:
The system enables CCTVs, which traditionally serve only surveillance purposes, to participate in driving negotiations by implementing message specification support. This multi-functionality allows existing CCTV infrastructure to contribute to vehicle communication, effectively expanding coverage without requiring dedicated RSU deployment everywhere.
2Adaptability or versatility
If CCTVs are excluded from driving negotiations, then message specification compatibility is maintained, but participation of imaging apparatus is prevented
Solution Approach 1:
The patent introduces message specifications as a standardized intermediary protocol that enables CCTVs to participate in driving negotiations. This mediator layer translates between the surveillance functions of CCTVs and the communication requirements of driving negotiations, allowing participation without compromising system compatibility or requiring complex custom integrations.
3Measurement precision
If unique vehicle IDs are transmitted, then vehicle identification accuracy is improved, but privacy protection is compromised
Solution Approach 1:
The patent extracts only the necessary identification information from unique vehicle IDs and transmits it through the standardized message specification protocol. This extraction approach maintains sufficient vehicle identification accuracy for driving negotiations while removing unnecessary personal identifiers, thereby protecting privacy without sacrificing functional requirements.

AI summary
A method according to an example embodiment of the present disclosure may comprise: when a vehicle being performing a driving negotiation moves, receiving, by an RSU, a first message including a first temporary identification (ID) of the vehicle from a first RSU on a past route of the vehicle; receiving, by the RSU, a second message including a second temporary ID of the vehicle identified by a closed-circuit television (CCTV) in a communicable area of the RSU from the CCTV; checking, by the RSU, the second temporary ID of the vehicle based on the second message received from the CCTV; and identifying, by the RSU, the vehicle as a target to extend the driving negotiation and performing the driving negotiation with the identified vehicle.
