Sequential Location Trace Clustering for Complex Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to provide adequate guidance for users in complex environments, such as airports or large complexes, as they typically only offer a straight line between the start and destination points, neglecting contextual and location-specific features.
Innovation Solution
The use of sequential location trace clustering to generate optimized navigable paths from a common start point to a common destination, taking into account historical rider paths and location-specific features like walls, stairs, and crosswalks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a straight line path is provided between start and destination points, then the navigation path is simple and easy to understand, but it fails to account for contextual and location-specific features in complex environments
Solution Approach 1:
The patent segments the navigation path into multiple waypoints that follow the actual physical layout of the environment (e.g., through doors, corridors, elevators) rather than providing a single straight line. This segmentation allows the path to accurately represent the navigable space while remaining understandable to users.
Solution Approach 2:
The patent incorporates local environmental features and constraints into the navigation path by using location trace data that reflects actual movement through specific areas. Each segment of the path is optimized for its local context, accounting for walls, stairs, and other location-specific characteristics.
2Manufacturing precision
If detailed context-aware navigation paths are generated using sequential location trace clustering, then navigation accuracy and effectiveness in complex environments improve, but the system complexity increases
Solution Approach 1:
The system performs preliminary clustering of location traces from multiple users to identify common paths and patterns before generating the final navigation route. This pre-processing organizes the data structure and simplifies the subsequent path generation process.
Solution Approach 2:
The patent uses location trace data from previous transportation services as a template or copy to generate new navigation paths. By clustering and reusing historical path patterns, the system can quickly generate accurate routes without processing every possible scenario from scratch.
3Manufacturing precision
If sequential location trace clustering is used to generate optimized paths, then the navigation path becomes more accurate and context-aware, but the processing time and computational resources increase
Solution Approach 1:
The system pre-clusters location traces and pre-computes common path patterns during off-peak times or in advance, so that when a new navigation request comes in, the system can quickly retrieve and adapt existing patterns rather than performing complex computations in real-time.
Solution Approach 2:
By copying and adapting historical path patterns from clustered location traces, the system can generate accurate navigation paths much faster than if it were to compute optimal routes from scratch for every request, significantly reducing processing time while maintaining accuracy.
Data Source
AI summary
Systems and methods for generating and presenting an optimized path using sequential location trace clustering is provided. The system receives a request for a transportation service from a client device of a user. The request indicates a destination point (i.e., a pickup location) and is associated with a start point (i.e., a location at a time the user requested the transportation service). Based on the start point and destination point, the system identifies one or more paths between the start point and the destination point, whereby the one or more paths are generated using sequential location trace clustering from previous transportation services involving the start point and the destination point. The system then causes presentation of a path of the one or more paths on a user interface on the client device of the user with which the user can use to navigate to the destination point.
