Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual updates of customs port data lead to untimely or false information, causing improper route planning, detours, and failure to navigate through ports, affecting user experience in global route planning.
Innovation Solution
A computer-implemented method and apparatus that acquire vehicle trajectory data within a predetermined area, match it with map data to identify intersection points, and determine the specific position of a traffic checkpoint based on the number of passing vehicles, eliminating the need for manual updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual updates of customs port data are performed at regular intervals, then data update frequency is maintained, but data timeliness and accuracy deteriorate
Solution Approach 1:
The system enables customs port data to update automatically through vehicle trajectory analysis. The processing system self-updates checkpoint data by detecting vehicle crossing behaviors at boundaries, eliminating the need for manual updates while ensuring data reflects actual port status and timing.
Solution Approach 2:
The system uses real vehicle trajectory data as feedback to continuously update customs port information. By monitoring actual vehicle crossing patterns and timing, the system adjusts and refines checkpoint data dynamically, ensuring accuracy and timeliness based on observed reality rather than fixed schedules.
2Ease of manufacture
If manual updates are used, then update process is simple, but route planning accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical update processes with an automated electronic processing system. The system uses computational algorithms to analyze vehicle trajectory data, automatically determine checkpoint positions and timing, and update navigation databases, substituting human manual work with automated electronic processing while dramatically improving accuracy.
3Device complexity
If customs port data is not timely updated, then manual update effort is reduced, but navigation reliability deteriorates
Solution Approach 1:
The navigation system automatically maintains up-to-date customs port information through self-service data collection and processing. Vehicle trajectory data is continuously collected and processed to update checkpoint information, allowing the system to maintain high navigation reliability without requiring manual intervention or increasing operational complexity.

AI summary
A method includes acquiring data of vehicle trajectories within a predetermined area, the predetermined area being determined by a boundary between two adjacent areas; matching the data of the vehicle trajectories with map data within the predetermined area to obtain a matching road network; determining a plurality of intersection points between the road network and the boundary, and dividing the plurality of intersection points into at least one group, a distance between any two intersection points in a first group of the at least one group being less than a preset value; and determining a specific position of a first traffic checkpoint in the first group based on a number of the vehicle trajectories each of the passing intersection points in the first group of the at least one group.
