Traffic simulation integration system based on interaction usages of macroscopic, mid-scopic and microscopic traffic simulation platforms

Abstract

The invention, which belongs to the virtual simulation technology field, more particularly relates to an integrated traffic simulation system based on interaction usages of macroscopic, mid-scopic and microscopic traffic simulation platforms. The system comprises a macroscopic traffic simulation module, a mid-scopic traffic simulation module, a microscopic traffic simulation module and a data collection and fusion module. The mid-scopic traffic simulation module is connected with the macroscopic traffic simulation module; the microscopic traffic simulation module is connected with the mid-scopic traffic simulation module; and the data collection and fusion module is respectively connected with the macroscopic traffic simulation module, the mid-scopic traffic simulation module and the microscopic traffic simulation module. According to the invention, on the basis of independent simulation of macroscopic, mid-scopic and microscopic traffic simulation platforms, interaction utilization of all layers of simulation systems and various simulation platform data is realized; traffic operation states of traffic flows and pedestrian flows large-scale activities can be comprehensively simulated; therefore, a technological basis can be provided for formulation of various traffic decision schemes of large-scale activities.

Description

technical field [0001] The invention belongs to the technical field of virtual simulation, and in particular relates to a traffic simulation integration system based on the interactive use of macro, medium and micro traffic simulation platforms. Background technique [0002] With the sustained and healthy development of my country's economy, my country has gradually become a world power in politics, economy, culture and sports. More and more world-class large-scale events are held in China, such as the 2008 Beijing Olympic Games, the 2010 Shanghai World Expo, and the 2010 Guangzhou The Asian Games and so on are staged in China. The holding of large-scale events enriches the material and cultural life of citizens, improves the city's domestic and international influence, and brings rare development opportunities and huge economic benefits to the city. However, while large-scale events produce huge economic benefits, their traffic characteristics of strong gathering and disper...

AI Technical Summary

Problems solved by technology

At present, the commonly used macro-, medium-, and micro-traffic simulation platforms are all independent, and it is difficult to conduct a comprehensive and systematic analysis of the urban traffic operation status and large-scale event traffic operation status as a whole. Therefore, a system that can integrate macro, medium, and micro traffic The simulation platform and the traffic simulation integration system for the interactive use of data of each simulation platform have become very important. It can not only comprehensively and systematically analyze the traffic operation conditions of cities and large-scale events, but also centralize data management and operation control to improve simulation accuracy.
