Traffic Control Unit Targeted Information Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent transportation systems inefficiently transmit traffic information, often broadcasting to unnecessary recipients, leading to waste of communication and processing resources, as they lack precise determination of traffic participant objects that truly need the information.
Innovation Solution
A method and device that determine an interaction coverage area based on traffic application type and information, allowing targeted transmission of traffic information to relevant participant objects, reducing resource waste by accurately identifying and supporting interaction with relevant traffic participants within the management area of a traffic control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic information is transmitted using broadcast manner, then all traffic participant objects can receive the information, but traffic information is transmitted to objects that do not need it, wasting communication resources
Solution Approach 1:
The patent determines the interaction coverage area based on the traffic application type and target object information, then identifies specific traffic participant objects within that area who actually need the information. This localizes the information transmission to only those objects within the coverage area who are relevant to the specific traffic scenario, rather than broadcasting to all objects universally.
Solution Approach 2:
The system uses the traffic application type as feedback to dynamically determine the interaction coverage area and identify appropriate recipient objects. Based on the type of traffic information being transmitted, the system adjusts the coverage area and filters recipient objects accordingly, creating a feedback loop that optimizes information distribution.
2Reliability
If traffic information is transmitted using broadcast manner, then information reaches all potential recipients, but processing resources are wasted on unnecessary information handling
Solution Approach 1:
The patent applies local quality by determining the interaction coverage area specific to each traffic application type and target object, then identifying only those traffic participant objects within the area who need the information. This ensures that processing resources are allocated only to relevant objects, improving overall system productivity while maintaining reliable information dissemination to those who require it.
Solution Approach 2:
The system performs partial action by transmitting information only to the subset of traffic participant objects that actually need it, rather than to all possible recipients. This partial transmission approach maintains sufficient information dissemination to relevant objects while avoiding the excessive processing burden of universal broadcasting.
3Loss of energy
If interaction coverage area is determined based on traffic application type and target object information, then traffic information can be transmitted in a targeted way, but the system complexity increases
Solution Approach 1:
The patent segments the traffic participant objects into different groups based on the determined interaction coverage area. By dividing the overall set of traffic objects into relevant and irrelevant subsets based on the coverage area calculation, the system can efficiently manage information transmission without having to process all objects uniformly, thus reducing overall system complexity while improving resource efficiency.
Solution Approach 2:
The system performs preliminary action by pre-determining the interaction coverage area based on the traffic application type and target object information before actual information transmission. This preliminary determination of the coverage area and identification of relevant objects simplifies the subsequent transmission process, as the system already knows which objects to target, reducing the complexity of real-time decision-making.

AI summary
The method includes: obtaining, by a first TCU, a traffic application type and first traffic information of a traffic target object; determining, by the first TCU, an interaction coverage area based on the traffic application type and the first traffic information of the traffic target object; determining, by the first TCU, a first area based on the interaction coverage area and a management area of the first TCU; determining, by the first TCU, a traffic participant object in the first area; and sending, by the first TCU, the first traffic information of the traffic target object to the traffic participant object; or receiving, by the first TCU, second traffic information sent by the traffic participant object, and sending the second traffic information to the traffic target object, so as to determine an interaction coverage area, and further accurately determine a traffic participant object in the interaction coverage area.
