Municipal engineering traffic accident processing system and method based on 3DGIS+BIM technology

Abstract

The invention discloses a municipal engineering traffic accident processing system and method based on a 3DGIS+BIM technology. The municipal engineering traffic accident processing system comprises adecision system, an execution system connected with the decision system, a power system and an information system; the decision system comprises a 3DGIS+BIM fusion management and control module, a VRinteraction module, a server module and a real-time road condition and event monitoring module; the execution system includes a traffic accident intelligent decision module, a traffic light signal control module and a municipal engineering traffic accident emergency processing device; the power system includes an electromechanical device module; the information system includes an information release module. The core of the municipal engineering traffic accident processing system and method is the 3DGIS+BIM fusion management and control module. By establishing a municipal engineering three-dimensional BIM model, all-direction observation of municipal engineering traffic accidents can be realized, decision makers and managers can grasp the whole situations, and electronization and informatization management of municipal engineering based on the BIM model is realized.

Description

technical field [0001] The invention relates to the field of municipal engineering disaster prevention and rescue, in particular to a municipal engineering traffic accident handling system and method based on 3DGIS+BIM technology. Background technique [0002] With the continuous acceleration of the urbanization process in our country, the urban traffic volume is increasing day by day, and traffic congestion has become one of the main problems faced by my country's current urban traffic. Municipal traffic is different from closed traffic such as expressways, railways, and subways. Features. Once a traffic accident occurs in major node projects such as municipal roads, viaducts, interchanges, and urban tunnels, it will affect the smooth flow of urban arterial roads, and even lead to regional traffic paralysis, forming rapid congestion from point to line to area, directly or indirectly causing considerable economic loss. Therefore, how to alleviate the traffic congestion caus...

AI Technical Summary

Problems solved by technology

During the peak travel period, the efficiency of this traffic accident handling method is low, the timeliness of rescue is insufficient, and the hidden dangers of accidents cannot be eliminated in time both subjectively and objectively, and it is difficult to meet the current rapid development of urban traffic.
