Dual-Path Code Association for Traffic Sensor Data Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networked traffic systems face inaccuracies in data exchange due to sensor system limitations and environmental conditions, leading to errors in position and motion data, particularly affecting vulnerable road users like pedestrians and bicycles.
Innovation Solution
A method where a first user sends sensor data and a unique code via two separate signal transmission paths, allowing a second user to receive and associate the data accurately, using radio transmission for longer distances and optical or LIDAR signals for clear views, ensuring precise recognition and categorization of road users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is exchanged via a single signal transmission path in a networked traffic system, then the communication process is simple, but the data accuracy and reliability are reduced due to sensor limitations and environmental conditions
Solution Approach 1:
The patent divides the code transmission into two separate signal transmission paths: a first signal transmission path for exchanging sensor data and a second signal transmission path for transmitting the code. This segmentation allows the system to use different transmission characteristics for different data types, improving overall reliability while maintaining manageable complexity in each individual path.
Solution Approach 2:
The patent introduces a code as an intermediary element that is transmitted separately from the sensor data. This code serves as a reference or identifier that helps verify and associate sensor data from different transmission paths, acting as a mediator that enhances data reliability without requiring direct correlation between the sensor data streams themselves.
2Measurement precision
If multiple signal transmission paths are used to improve data association accuracy, then the data reliability improves, but the system complexity increases
Solution Approach 1:
The patent segments the information transmission into distinct components: sensor data transmitted via a first signal transmission path and a separate code transmitted via a second signal transmission path. This segmentation enables precise association of data from multiple sources while keeping each transmission path relatively simple and manageable.
Solution Approach 2:
The code is transmitted in advance or simultaneously with the sensor data through a dedicated second signal transmission path. This preliminary action establishes a reference framework that enables accurate association of sensor data from the first transmission path, improving measurement precision without requiring complex real-time processing of multiple data streams.
3Reliability
If sensor data is transmitted without a separate code, then the communication protocol is simpler, but the association of sensor data from different users becomes error-prone
Solution Approach 1:
The patent introduces a code as an intermediary element that facilitates reliable association of sensor data from different users. This code is transmitted separately via a second signal transmission path and serves as a unique identifier or reference that enables the receiving system to correctly associate sensor data with the appropriate user or data source, significantly improving association reliability.
Solution Approach 2:
The communication protocol is segmented into two distinct transmission paths: one for sensor data and another for the association code. This segmentation simplifies the overall protocol design by separating the data transmission function from the identification/association function, making each component easier to implement and manage while improving overall reliability.

Function Achieved in This Case
This method provides accurate and reliable data association, reducing errors and improving recognition of vulnerable road users even in high-density traffic scenarios, enhancing traffic flow and safety by correcting inaccuracies in sensor data.
Implementation Method 1
a first user sends pieces of exchange information with the aid of a first signal transmission path. The pieces of exchange information in this case include first sensor data of the first user as well as an individual code representing the first user.
Implementation Method 2
The first user sends the code in this case also with the aid of at least one further second signal transmission path.
Implementation Method 3
using radio transmission for longer distances and optical or LIDAR signals for clear views
Implementation Method 4
the second user ascertains, with the aid of a surroundings sensor system, second sensor data by detecting surroundings, the second user, with the aid of the surroundings sensor system, also receiving the code sent via the second signal transmission path.
Data Source
AI summary
A method for the communication of at least two users of a networked traffic system. A first user sends pieces of exchange information using a first signal transmission path, the pieces of exchange information including first sensor data of the first user and a code representing the first user. The first user sends the representative code or one further representative code using at least one second signal transmission path. A second user receives the pieces of exchange information via the first signal transmission path. The second user ascertains using a surroundings sensor system second sensor data by detecting surroundings. The second user receives using the surroundings sensor system the code sent via the second signal transmission path. The second user associates the first sensor data and the second sensor data with one another with the aid of the representative code and/or with the aid of the further representative code.
