Route Planning Device Line of Interest Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems rely on point-of-interest (POI) based route planning, which can be cumbersome and inefficient for users who want to create customized routes that follow a specific line of interest, as they require multiple inputs and do not effectively account for real-time road and traffic conditions.
Innovation Solution
A route planning device and method that identifies a line of interest on a map, acquires road and traffic information, and calculates a navigation route that best matches the user's drawn line while adhering to predefined road and traffic constraints, offering a more user-friendly and efficient route planning experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If POI based route planning is used, then route calculation can be performed with simple point inputs, but the process becomes cumbersome and inefficient for users wanting customized routes along a specific line
Solution Approach 1:
The patent transitions from point-based input (0D/1D) to line-based input (1D/2D) on the map interface. Users can draw a continuous line across the map to define their desired route path, moving from discrete point selection to continuous spatial expression, thereby enabling more intuitive and efficient customized route planning
2Adaptability or versatility
If users draw a custom line of interest on the map, then route customization is improved, but the system must process and match the drawn line with actual road networks
Solution Approach 1:
The system introduces an intermediary processing layer that contains the drawn line of interest between parallel road segments. This intermediary structure allows the system to match the user's custom line with actual road networks by identifying intersections and constructing routes that follow real roads while respecting the user's desired path, thereby balancing customization with system feasibility
3Reliability
If real-time road and traffic information is incorporated, then route accuracy and relevance are improved, but data acquisition and processing requirements increase
Solution Approach 1:
The system performs preliminary acquisition and organization of road and traffic information before the route calculation process. By pre-loading and structuring the necessary data, the system reduces the complexity of real-time data processing during route calculation, while still ensuring that the final route reflects current road conditions and traffic status
Data Source
AI summary
Provided is a device and a method for route planning. The route planning device (100) may include a data interface (128) coupled to a road and traffic data source (160); a user interface (170) configured to display a map and receive a route planning request from a user, the route planning request including a line of interest on the map; a processor (110) coupled to the data interface (128) and the user interface (170). The processor (110) may be configured to identify the line of interest in response to the route planning request; acquire, via the data interface (128), road and traffic information associated with the line of interest from the road and traffic data source (160); and calculate, based on the acquired road and traffic information, a navigation route that matches or corresponds to the line of interest and meets or satisfies predefined road and traffic constraints.
