Precision Traffic Indication via Road Subsection Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic indication systems, such as the Traffic Message Channel (TMC), only report traffic flows for entire road segments, which can be inaccurate as conditions vary along the segment, failing to provide precise information for specific subsections.
Innovation Solution
Collecting and analyzing mobile device data from multiple devices associated with a road system divided into subsections to calculate and indicate different traffic flow levels for each subsection, using thresholds for the number of readings and variance in traffic flow, allowing for more accurate characterization and representation of traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traffic flow is indicated for entire road segments using TMC addressing scheme, then the system complexity is reduced and ease of operation is improved, but the measurement precision of traffic flow is degraded
Solution Approach 1:
The patent divides road segments into multiple subsections and calculates traffic flow separately for each subsection. This segmentation allows the system to provide more precise traffic flow information for specific portions of roads while maintaining a manageable system structure through hierarchical organization of road segments and subsections.
Solution Approach 2:
The patent applies local quality by providing differentiated traffic flow indications for different subsections of the same road segment. Each subsection can have its own traffic flow characteristics represented, allowing accurate local traffic conditions to be captured without requiring complete system redesign.
2Loss of information
If traffic flow is indicated for entire road segments, then the data processing volume is reduced, but the loss of information about varying traffic conditions along the segment increases
Solution Approach 1:
By segmenting road segments into subsections, the system captures traffic condition variations along the road while processing data in manageable units. This approach preserves information about local traffic conditions without requiring processing of excessively large data sets.
Solution Approach 2:
The patent processes traffic data at the subsection level rather than aggregating all data at the segment level, providing more detailed traffic condition information. This partial action approach processes only the necessary level of detail for each subsection, balancing information preservation with processing efficiency.

AI summary
Precision traffic flow indication may involve receiving device data over a period of time representing a plurality traffic flow readings associated with a road involving a plurality of subsections. Calculating traffic flows and determining road subsections having similar traffic flows may also be involved. Also, indicating a different traffic flow level for a first subsection and a second subsection of road may be involved.
