Abstract

The invention discloses a method for identifying the intention of transportation capacity. Through the research on the truck transportation scene and the mining of the truck track data, the concept of "willing value" of the truck relative to other regions is proposed, and the willingness of each truck relative to each region is calculated. value, and then obtain the transportation intention of the area under test for other areas. Through the technical solution of the present invention, it is possible to avoid the impact on the recognition result of the traffic capacity carrying intention in a specific direction; all long-distance trucks are divided into local trucks and out-of-town trucks, and different methods are used to calculate the willingness value of them, so as to improve the calculation accuracy; The consideration factors are comprehensive and operable, and the calculated results are accurate.

Description

technical field [0001] The invention belongs to the technical field of trajectory data mining, and in particular relates to a method for identifying traffic capacity and carrying intentions based on truck trajectory data. Background technique [0002] With the continuous and rapid development of my country's highway infrastructure construction and the continuous progress of the automobile industry, road freight transportation occupies an increasingly important position in the comprehensive transportation system. At the same time, with the increasingly active commodity economy, the increasing frequency of inter-regional economic exchanges and cargo exchanges, and the improvement of road conditions, the average distance of cargo transportation has increased, leading to the further increase in the importance of long-distance freight. However, the efficiency of my country's road freight is low, and the empty driving rate of vehicles is over 40%. The main reason for the high rat...
