Road Cell Mapping for Lane-Specific Hazard Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively address the irregular and unpredictable nature of road defects such as potholes and cracks, leading to unexpected dangers for drivers and increased accident risks due to sudden braking.
Innovation Solution
A method is developed to divide road surfaces into cells on a precise map, integrating boundary and centerline information, and display road conditions using a server that generates and displays condition information within these cells, including road surface and danger information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If road conditions are displayed without dividing into cells, then the system is simple, but the precision of road condition information is insufficient
Solution Approach 1:
The road is divided into multiple cells along the longitudinal direction, with each cell containing road condition information for a specific road section. This segmentation allows precise location identification of road defects while maintaining manageable data structure through standardized cell configurations.
2Measurement precision
If road conditions are displayed without lane differentiation, then the display is simple, but the accuracy of lane-specific hazard information is insufficient
Solution Approach 1:
Each cell contains lane information structures that specifically store road condition data for different lanes within that cell. This allows lane-specific hazard information to be precisely recorded and retrieved, with each lane having its own condition profile including defect locations and types.
3Reliability
If comprehensive road condition data is collected, then the reliability of hazard information improves, but the loss of time for data processing increases
Solution Approach 1:
Road condition information is pre-processed and organized into standardized cell structures during data collection, with defects categorized and located within specific cells and lanes. This preliminary organization enables rapid retrieval and display of hazard information without requiring extensive processing when data is requested.

AI summary
Provided are a device and method for displaying road conditions on the basis of road cells. The method includes receiving, by a server, a map including boundary and centerline information of a road and databasing the map, receiving, by the server, condition information of the road, generating, by the server, one or more cells by dividing the road on the map, and displaying, by the server, the condition information of the road in the cells. According to the method, road condition information is generated lane by lane so that a user can understand road conditions more intuitively.
