AI Technical Summary
Existing methods for calculating cross-sectional flow in waterways are computationally intensive, making it difficult to improve efficiency and accuracy, and also making it difficult to accurately determine upstream and downstream flow.
A waterway network cross-sectional flow statistics system based on AIS data is adopted. By performing gridded preprocessing on the waterway data, matching is performed using overlapping grids and waterway topology. The matching results of the preceding trajectory points are corrected by combining the subsequent trajectory points, thereby improving the matching accuracy and performing flow analysis.
It improves the accuracy of waterway intersection matching and the calculation efficiency of flow statistics, and enables accurate analysis of upstream and downstream flow.
