Lane-Level Difficulty Navigation Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems fail to accurately account for lane-level difficulty in maneuvers, leading to routes that may include challenging turns that exceed driver capabilities, as they rely on averaged traffic information that does not distinguish between different types of lanes, resulting in frustrating and potentially unsafe situations for drivers.
Innovation Solution
A system that computes lane-level difficulty scores based on traffic information, such as speed, traffic volume, and wait time, and routes vehicles to include only maneuvers with difficulty scores below a specified preference, ensuring safer and more comfortable routes by filtering out challenging turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If navigation systems use averaged traffic information to compute routes, then routing efficiency is improved, but lane-level difficulty is not accurately accounted for
Solution Approach 1:
The patent segments the traffic information analysis at the lane level rather than using averaged data across all lanes. Each lane is individually evaluated for difficulty based on its specific traffic characteristics, enabling precise measurement of lane-level difficulty while maintaining overall routing efficiency through systematic processing of segmented data.
Solution Approach 2:
The patent applies local quality by evaluating each lane's specific characteristics (traffic volume, speed, wait time) independently to determine its difficulty level. This allows the navigation system to account for local variations in lane difficulty while maintaining efficient routing through the entire path.
2Adaptability or versatility
If navigation systems include all possible maneuvers in routes, then route options are increased, but driver safety and comfort are compromised
Solution Approach 1:
The patent dynamically filters route maneuvers based on lane-level difficulty scores and driver preferences. The system adaptively adjusts route recommendations by excluding maneuvers with difficulty scores exceeding the driver's threshold, thereby ensuring safety and comfort while maintaining versatile routing options within acceptable parameters.
Solution Approach 2:
The patent changes the parameter of maneuver inclusion by using lane-level difficulty scores as a filtering criterion. Routes are computed to include only maneuvers with difficulty scores below a specified threshold, transforming the set of available maneuvers to ensure driver safety and comfort while preserving route versatility within acceptable difficulty parameters.
3Ease of operation
If navigation systems provide detailed lane-level difficulty scores, then driver comfort is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by having the system automatically compute and provide lane-level difficulty scores based on objective traffic data (volume, speed, wait time). The system serves the driver's need for comfort information without requiring manual input or complex user interaction, maintaining ease of operation while managing system complexity through automated processing.
Data Source
AI summary
Customized routing of vehicles is performed based on lane-level difficulty includes extracting data elements from traffic information indicative of performance of maneuvers by the vehicles. Raw difficulty scores are determined for each of the maneuvers based on the data elements. Lanes of travel are identified for the maneuvers. For each lane, a lane-level difficulty score is generated based on the raw difficulty scores corresponding to the maneuvers using that lane. Vehicles are routed accounting for the lane-level difficulty scores to include only maneuvers that have lane-level difficulty scores at or below a difficulty preference.
