Abstract

The invention belongs to the technical field of traffic simulation, and provides a real-time online traffic simulation system comprising a detection data acquisition module, an initial matrix acquisition module, a dynamic path decision module, a mesoscopic traffic flow simulation module, a precision calculation module, a dynamic OD estimation module, a short-time traffic state prediction module, amesoscopic and microscopic fusion traffic simulation module and a real-time online module. According to the simulation system, the value of multi-source data can be fully utilized and mined, OD pathset more conforming to actual traffic conditions is generated, the timeliness of the simulation data is fully considered, and the accuracy of dynamic OD estimation is improved.

Description

technical field [0001] The application belongs to the technical field of traffic simulation, and in particular relates to a real-time online traffic simulation system and method. Background technique [0002] Traffic simulation technology is already one of the commonly used technical means in traffic control. In recent years, with the popularization of personal computers and the rapid improvement of its computing speed, the development and application of a new generation of traffic simulation software has made great progress. In the past, traffic simulation mainly relied on comprehensive traffic planning tools (such as TransCAD, EMME / 2, TRIPS, and VISUM, etc.) to make traffic demand forecasts, and further used traditional traffic simulation software to analyze the dynamic relationship between traffic demand and supply on the road network in the future. To make up for the shortcomings of the static traffic allocation model, verify its assumptions (such as passing capacity an...
