Guidance Zone Temporary ID Assignment for Non-Overlapping Vehicle Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In V2X communication systems, existing methods for assigning temporary identifiers to vehicles within a guidance zone do not guarantee non-overlapping identifiers, leading to potential mismatches and service disruptions when vehicles enter or exit the zone.
Innovation Solution
An apparatus and method that utilize a vehicle detector and RSU module to assign a unique temporary identifier to a vehicle based on its position information upon entering a guidance zone, ensuring the identifier does not overlap with other vehicles within the zone, and maintains it until the vehicle exits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each vehicle generates a random temporary identifier, then the identifier assignment is simple and fast, but there is no guarantee that identifiers will not overlap between vehicles within the guidance zone
Solution Approach 1:
The RSU performs preliminary actions by detecting vehicles entering the guidance zone before identifier assignment, obtaining their position information in advance. The system then assigns identifiers sequentially based on detection order, ensuring uniqueness before vehicles actually communicate, thus resolving the contradiction between fast assignment and guaranteed uniqueness
Solution Approach 2:
The RSU acts as an intermediary between vehicles and the identifier system. Instead of vehicles generating identifiers independently (which causes overlaps), the RSU mediates the process by detecting vehicles, obtaining their position information, and assigning unique identifiers sequentially, thus ensuring both uniqueness and systematic assignment
2Reliability
If a vehicle changes its temporary identifier during ongoing guidance service, then privacy protection is improved, but the identifier may mismatch with vehicle identification information recognized by the infrastructure, leading to service disruption
Solution Approach 1:
The system applies partial privacy protection by assigning temporary identifiers only when vehicles enter the guidance zone, rather than changing identifiers continuously or excessively. This partial approach maintains service continuity while providing sufficient privacy protection for the duration of the guidance service, resolving the contradiction between privacy and service continuity
Solution Approach 2:
The temporary identifier system is made dynamic by being assigned at the moment of entry into the guidance zone and maintained throughout the service period. This dynamic assignment ensures the identifier remains valid and matched with vehicle identification information throughout the ongoing service, preventing mismatches while still protecting privacy
3Reliability
If infrastructure assigns temporary identifiers to vehicles, then accurate identification and message exchange are improved, but system complexity increases due to additional detection and assignment mechanisms
Solution Approach 1:
The RSU is designed with multi-functionality, serving both as a vehicle detection device and an identifier assignment device. By combining these functions in a single infrastructure component, the system achieves accurate vehicle identification without proportionally increasing overall system complexity, as the same hardware performs multiple tasks
Solution Approach 2:
The system implements self-service by having the vehicle detector automatically detect vehicles and the RSU automatically assign identifiers based on detection information. This automated self-service process reduces the need for manual intervention and complex management mechanisms, achieving reliable identification while keeping the system relatively simple

AI summary
Disclosed is an apparatus for assigning a temporary identifier for a guidance zone, including a vehicle detector configured to detect a vehicle in a guidance zone; and a roadside unit (RSU) module configured to, when a guidance participation request message is transmitted to the vehicle entering the guidance zone and a guidance participation response message is received from the vehicle, assign a temporary identifier to the vehicle based on vehicle detection information detected through the vehicle detector and the guidance participation response message.
