Route Validation via Waypoint Proximity in Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of software mapping systems often face frustration in selecting the most accurate route to a destination due to the generation of multiple routes with varying accuracy, especially when they are unfamiliar with the route and cannot specify waypoints.
Innovation Solution
A method and system for verifying a generated route in computer-assisted navigation by determining if a specified waypoint is proximate to the route, and optionally generating an alternative route that includes the waypoint if it is not, using a route validation module within a mapping application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different routes are generated to a specified destination, then route options increase and user preference flexibility improves, but route selection reliability deteriorates because users cannot determine which route is accurate
Solution Approach 1:
The system automatically generates waypoints based on the generated route and feeds this information back to verify route accuracy. The waypoints act as feedback markers that confirm whether the route passes through expected locations, allowing the system to self-validate route accuracy without user intervention.
Solution Approach 2:
The system performs automatic route verification by generating waypoints and comparing them against the route geometry. This self-service mechanism eliminates the need for user knowledge of intermediate locations, as the system independently determines route accuracy through automated waypoint validation.
2Adaptability or versatility
If waypoints are used to customize a generated route, then route personalization improves, but ease of operation deteriorates because users must know the waypoints in advance
Solution Approach 1:
Instead of requiring users to input waypoints to customize routes, the system inverts the approach by automatically generating waypoints from the route itself. This reversal eliminates the need for user knowledge of intermediate locations while still enabling personalized route customization through automatically generated waypoints.
Solution Approach 2:
The system automatically generates waypoints based on the route geometry and user preferences, performing the waypoint creation service without user intervention. This self-service approach maintains route personalization capability while eliminating the operational burden of manual waypoint specification.
3Ease of operation
If automatic waypoint generation is implemented, then ease of operation improves, but device complexity increases due to additional validation functionality
Solution Approach 1:
The existing route generation functionality is extended to also perform waypoint generation and validation. The same algorithmic framework used for route calculation is leveraged to generate waypoints, making the validation mechanism a natural extension of existing functionality rather than a completely separate system, thereby limiting the increase in complexity.
Data Source
AI summary
An approach to validate a route generated by machine logic may be provided. The approach may include a user inputting an origin and destination. The approach may include generating a route from the user input by machine logic. The approach may additionally include the user inputting one or more waypoints. The approach may determine if the waypoint(s) is located on the generated route. If it is determined the waypoints are not on the generated route, a second route may be generated, by machine logic, with the waypoint(s) on the route. The approach may further include presenting the route to a user for validation.
