Embodiment 2

[0070] In the current actual engineering design and simulation process, because the developers of each software are not the same company, the formats of various 2D drawings and 3D drawings are different, and there is no common platform that can be compatible with multiple design drawing files at the same time , unable to effectively parse multiple 2D and 3D formats and carry out informatization classification.

[0071] In order to solve the above-mentioned technical problems, the following technical solution is adopted on the basis of Embodiment 1: Split the building information model data into a graphic model and a data model, classify and process through custom fields, and convert it into a standardized model.

[0072] The data contained in BIM (Building Information Modeling) can be divided into two categories: graphic model and data model. The two types are classified and processed according to their data characteristics and custom fields to realize the import of multi-sourc...

Description

technical field [0001] The invention relates to the technical field of road design engineering simulation, in particular to a road simulation platform based on intelligent body traffic flow simulation. Background technique [0002] In the process of road design, BIM (Building Information Modeling) can be used to simulate the surrounding conditions of the designed road, including houses, mountains, rivers, vegetation, etc., to realize engineering visualization. In addition to the above-mentioned fixed objects, the traffic flow on the road is also one of the main considerations in road design. Traffic flow will affect the width of the road, the number of lanes, the length of the ramp, etc.; flow simulation. [0003] In order to achieve the above effects, a series of software and software combinations are usually used to build a design platform, and import road design drawings into the platform to realize 3D simulation. However, in the prior art, the simulation platforms for ...
