Traffic Information Delivery via Reference Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently and reliably providing frequently changing traffic information to road users, particularly vehicles, due to limited bandwidth and transmission capacity, which can lead to high data volumes and inefficient data transmission.
Innovation Solution
A method and device that determine an information region for a road user and transmit reference information to enable direct communication with relevant communication partners, allowing for optimized data transmission by separating reference information from actual traffic information, using a grid network to subdivide the road network into cells, and adapting communication protocols for efficient data exchange.

Engineering Contradiction Analysis
1Reliability
If traffic information is transmitted from a central unit to vehicles, then road users can obtain real-time traffic information, but the bandwidth and transmission capacity are limited
Solution Approach 1:
The system segments traffic information into two categories: frequently changing information (provided by communication partners near the road user) and less frequently changing information (provided by the central unit). This segmentation allows the system to optimize transmission for each type, reducing overall data volume while maintaining reliability.
Solution Approach 2:
The patent introduces communication partners (infrastructure units or other road users) as intermediaries that provide frequently changing traffic information directly to the road user's vehicle. This intermediary approach reduces the data burden on the central unit and improves transmission efficiency by localizing information sources.
2Productivity
If reference information is transmitted from central unit to road user, then communication partners can be identified for direct communication, but additional transmission steps are required
Solution Approach 1:
The central unit performs preliminary action by transmitting reference information (identifiers and communication addresses) of relevant communication partners to the road user in advance. This allows the vehicle to directly contact the appropriate infrastructure units or other vehicles without requiring complex real-time discovery mechanisms, improving transmission efficiency.

AI summary
A method for providing traffic information for a traffic participant, in particular for a road user such as a vehicle includes determining an information region for the traffic participant, providing traffic information for the information region of the traffic participant from one or more communications partners associated with the information region. In addition, the method includes sending reference information relating to the one or more communications partners to the traffic participant which the traffic participant may use to obtain traffic information from the one or more communication partners associated with the information region.
