Abstract

The invention relates to a dynamic traffic simulation platform which comprises a perception layer, a fusion layer, an application layer and a presentation layer. The perception layer is connected with a dynamic traffic data collecting device, multivariate heterogeneous traffic flow data are obtained and transmitted to the fusion layer in real time, and the fusion layer is connected with the application layer. The multivariate heterogeneous traffic flow data and GIS data are received for processing, the application layer obtains road network dynamic traffic flow data, and a traffic simulation model is formed. Through the traffic simulation model and a traffic OD matrix, dynamic traffic simulation is performed, and the presentation layer receives the traffic simulation result of the dynamic traffic simulation in the application layer, and provides service application and presentation to a terminal client. The problem that in the prior art, a large number of real-time dynamic traffic data can not be rapidly matched with a road section well is solved. Therefore, the multifunctional dynamic traffic simulation platform is capable of performing OD back stepping and real-time dynamic traffic early warning on dynamic traffic flows on the basis of a GIS grid rapid matching technology.

Description

technical field [0001] The invention relates to a traffic simulation platform, in particular to a dynamic traffic simulation platform, which belongs to the technical field of traffic simulation. Background technique [0002] Traffic simulation is a traffic analysis technology and method that uses computer digital models to reflect complex road traffic phenomena developed with the advancement of computer technology since the 1960s. Road traffic simulation is a simulation technology that reproduces the time and space changes of traffic flow , it is based on the basic theories and professional technologies in the fields of similarity principle, information technology, system engineering and traffic engineering, uses the computer as the main tool, uses the system simulation model to simulate the running state of the road traffic system, and uses digital or graphical methods to describe Dynamic traffic system. [0003] As the contradiction between supply and demand in transporta...
