Route Scoring for Fair Driving Performance Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle telematics systems fail to accurately compare driving performance across different routes due to varying road conditions, leading to misleading risk assessments and inaccurate insurance and fleet management decisions.
Innovation Solution
Implementing route scoring systems that normalize driving performance scores based on road infrastructure features and conditions, allowing for fair comparisons and predictions of driving performance on new or hypothetical routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional telematics data collection is used without route scoring, then data collection is simple and straightforward, but driving performance comparison becomes misleading and inaccurate
Solution Approach 1:
The patent introduces route scoring as an intermediary element that mediates between raw telematics data and driving performance assessment. The route score, calculated from road infrastructure data, serves as a normalization factor that adjusts driver scores to account for route difficulty, enabling accurate comparisons without requiring complex direct analysis of all route variations
Solution Approach 2:
The patent transforms the driving performance assessment by introducing a new parameter (route score) derived from road infrastructure characteristics. This parameter change allows the system to normalize driver performance data across different route conditions, converting incomparable raw scores into comparable normalized scores through mathematical adjustment
2Measurement precision
If route scoring normalization is implemented, then driving performance comparison accuracy improves, but data processing and calculation complexity increases
Solution Approach 1:
The patent performs preliminary calculation of route scores using road infrastructure data before the actual driving performance assessment. By pre-computing the route difficulty metrics and storing them, the system avoids redundant calculations during performance assessment, thereby maintaining high accuracy while improving processing efficiency during actual use
Solution Approach 2:
The patent segments the driving performance assessment into distinct components: route score calculation from infrastructure data, driver score calculation from telematics data, and normalized score derivation. This segmentation allows each component to be processed independently and optimized separately, improving overall system efficiency
3Reliability
If route difficulty factors are considered, then fair comparison between drivers on different routes is achieved, but the assessment system becomes more complex
Solution Approach 1:
The patent applies equipotentiality by normalizing driver scores to a common reference frame based on route difficulty. The route score acts as a normalization factor that equalizes the playing field, allowing drivers on different route types (highway vs. city streets) to be compared as if they had driven on the same route, thereby achieving fair comparison without requiring complex route-matching algorithms
Data Source
AI summary
In a computer-implemented method of assessing driving performance using route scoring, driving data indicative of operation of a vehicle while the vehicle was driven on a driving route may be received. Road infrastructure data indicative of one or more features of the driving route may also be received. A route score for the driving route may be calculated using the road infrastructure data, and a driving performance score for a driver of the vehicle may be calculated using the driving data and the route score for the driving route. Data may be sent to a client device via a network to cause the client device to display the driving performance score and/or a ranking based on the driving performance score, and/or the driving performance score may be used to determine a risk rating for the driver of the vehicle.
