Embodiment Construction

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0063] It should be noted that all directional indications (such as up, down, left, right, front, rear, etc.) If the positional relationship, movement conditions, etc. change, the directional indication will also change accordingly, and the connection may be a direct connection or an indirect connection.

[0064] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three rel...

Abstract

The present invention provides a GIS-based three-dimensional modeling method and system for a real scene of traffic flow, wherein the method includes: determining a preset location, obtaining vehicle information and position information of the preset location, and the first vehicle's first vehicle at a second preset time. The second position information is used to calculate the first relaxation degree and the second relaxation degree, and the relaxation degree and the relaxation flow number of the preset location are obtained, so as to establish a traffic flow relaxation degree model. The beneficial effects of the present invention are: by acquiring vehicle information at preset locations in GIS data, and acquiring target relaxation and relaxation flow numbers at each preset location based on the vehicle information, the resulting vehicle flow relaxation model can be more easily predicted. In addition, the present application is not limited to the density, but reflects the degree of congestion of the traffic flow through the relaxation degree, thereby realizing the direct response to the degree of congestion of the traffic flow, which is more accurate than the traditional density detection method for judging the congestion degree of the expressway.

Description

technical field [0001] The invention relates to the field of computers, in particular to a GIS-based real scene three-dimensional modeling method and system for traffic flow. Background technique [0002] The expressway system is an important means of transportation of people and goods in the region. At present, the real scene modeling of traffic flow on the expressway mainly relies on GIS data for modeling. However, there are many large discrete spatial flow data for GIS data. At present, it is mainly By predicting the quantity of traffic flow, that is to predict the density on the expressway, however, the high density on the expressway cannot directly reflect the congestion of the traffic flow. Contents of the invention [0003] The main purpose of the present invention is to provide a GIS-based method and system for three-dimensional modeling of real traffic flow, aiming at solving the problem that the prediction of density cannot directly reflect the congestion of traf...
