Road Work Area Characteristic Determination via Vehicle Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for informing drivers about road work areas are limited, often providing only the starting point of road works, leading to uncertainty and increased stress, and rely on manual database updates which can be inaccurate, causing traffic congestion and safety risks.
Innovation Solution
A method that determines actual road work area characteristics by collecting and analyzing vehicle status information, including position, speed, and lane data from vehicles that have passed or will pass the road work area, allowing for continuous and accurate updates of road work information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual database updates are used for road work information, then implementation simplicity is maintained, but information accuracy and reliability deteriorate
Solution Approach 1:
The system enables automatic self-updating of road work information by having vehicles autonomously detect road work signs, extract characteristics, and update the database without manual intervention. This resolves the contradiction by eliminating the need for manual updates while ensuring continuous accurate information.
Solution Approach 2:
The system implements feedback loops where vehicle-detected road work information is continuously fed back to update the central database, which then provides updated information back to vehicles. This automatic feedback mechanism ensures information accuracy without manual intervention.
2Loss of information
If only starting point information is provided for road works, then information completeness is reduced, but communication simplicity is improved
Solution Approach 1:
The road work information is segmented into multiple characteristic parameters including starting point, ending point, type of road work, number of lanes affected, and expected duration. This segmentation allows comprehensive information to be transmitted in a structured, manageable format without overwhelming complexity.
Solution Approach 2:
The system transforms road work information from a single starting point coordinate into multiple descriptive parameters (start position, end position, road work type, lane closure information). This parameter expansion provides complete information while maintaining clear, standardized communication protocols.
3Speed
If road work information is provided close to the starting point, then response time is reduced, but driver preparation time deteriorates
Solution Approach 1:
The system performs preliminary action by detecting and communicating road work information to vehicles before they reach the road work area. Vehicles receive advance notice of road work characteristics, allowing drivers to prepare appropriately well before encountering the actual road work zone.
Solution Approach 2:
The information delivery system dynamically adjusts based on vehicle position and speed, providing road work information at optimal times. The system can deliver information at varying distances from the road work start point depending on vehicle approach speed, ensuring drivers receive adequate preparation time while maintaining efficient information delivery.

AI summary
The present disclosure relates to a method for determining a road work area characteristic set comprising at least one characteristic associated with a road work area. The method comprises: determining a starting position of the road work area, receiving actual vehicle status information from each vehicle in a vehicle set, wherein each vehicle in the vehicle set has passed or is determined to pass the starting position of the road work area, the actual vehicle status information being generated by an individual generation component associated with the vehicle, the actual vehicle status information comprising vehicle position data for the vehicle, determining an actual vehicle status information set from the actual vehicle status information of each vehicle in the vehicle set, and determining the road work area characteristic set using the actual vehicle status information set.
