Abstract

The invention discloses a BIM and Vissim fused construction traffic organization three-dimensional analogue simulation method, wherein the method comprises the steps: constructing a construction traffic organization local control area live-action terrain model by utilizing an unmanned aerial vehicle oblique photography technology, and providing a real data terrain for construction traffic organization simulation; on the basis of the constructed live-action terrain model, establishing a whole-line BIM model and a necessary traffic auxiliary facility BIM model within a construction traffic organization range; and on the basis of the whole-line BIM model within the construction traffic organization range, constructing whole-line construction traffic organization visual simulation by using traffic simulation analysis software according to the traffic organization implementation scheme, and realizing conversion from a two-dimensional plane to a three-dimensional display of the traffic organization implementation scheme and the like. The method has the advantages that interconnection and intercommunication of traffic organization three-dimensional simulation software and Vissim traffic analysis data are achieved, meanwhile, real traffic flow data of the expressway are associated, and the real traffic condition under the traffic organization scheme implementation condition is highly restored.
