Introduction

Penglong Li is an innovative inventor based in Changsha, China. He has made significant contributions to the field of traffic flow analysis through his unique detection methods. His work focuses on improving the understanding of key road-sections in urban environments.

Latest Patents

Penglong Li holds a patent for a "Detection method of key road-sections based on Ricci flow." This method involves building a weighted road network using static road network data and actual traffic flow data. It calculates initial values of Olivier Ricci curvature at different times and employs a Ricci flow iterative process to obtain a weight system for the edges of the weighted road network. The method effectively calculates the direction and degree of weight change for each edge corresponding to road-sections, setting a threshold to extract key road-sections. This innovative approach addresses the limitations of existing methods that do not fully consider the actual distribution and transmission characteristics of traffic flow, resulting in more accurate detection of key road-sections.
