Lane Guidance Insertion for Navigation Maneuver Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems often fail to provide adequate guidance, leading to unintended maneuvers due to inadequate lane positioning and complex road configurations, resulting in users going off-route.
Innovation Solution
A navigation service that generates additional guidance instructions based on lane connectivity, road segment properties, and user position, providing lane and smart guidance to ensure correct lane positioning and prevent unintended turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation instructions are provided at three distinct intervals (after prior maneuver, one mile before, and 250 feet before), then the basic navigation guidance is provided, but users may still end up in wrong lanes or make unintended maneuvers due to insufficient intermediate guidance
Solution Approach 1:
The navigation route is segmented into multiple sections with guidance instructions inserted at critical points between the three standard intervals. The system identifies specific segments where lane positioning is critical and provides targeted guidance instructions for those segments, breaking down the continuous route into manageable portions that require specific attention.
Solution Approach 2:
The system provides preliminary lane positioning instructions before the user reaches critical decision points. By analyzing route geometry and lane configurations in advance, the system inserts guidance instructions at optimal positions that prepare users for upcoming maneuvers, ensuring they are in the correct lane before reaching intersections or exits.
2Reliability
If additional guidance instructions are inserted between standard navigation instructions, then lane positioning accuracy is improved, but the quantity of navigation information increases which may overwhelm users
Solution Approach 1:
Additional guidance instructions are provided locally at specific critical segments of the route rather than uniformly throughout. The system identifies locations where lane positioning is critical (such as before intersections, exits, or complex maneuvers) and inserts guidance only at those locations, providing enhanced detail where needed while maintaining simplicity elsewhere.
Solution Approach 2:
The system applies partial action by providing additional guidance only when and where it is truly necessary for safe and accurate navigation. Rather than providing continuous or excessive instructions that would overwhelm users, the system selectively adds guidance at critical points where the risk of wrong lane positioning is highest.

AI summary
In some implementations, a navigation service can provide a plurality of navigation instructions for a user to traverse a route to an intended destination. The navigation service can also identify at least one portion of the determined route that requires additional guidance based on one or more factors. For each portion of the route that requires additional guidance, the navigation service may generate one or more additional guidance instructions to be inserted within the plurality of navigation instructions, forming an enhanced set of instructions for traversing the route.
