Embodiment Construction
[0062] The following is based on Figure 1 to Figure 5 The specific embodiment of the present invention is further described:
[0063] This embodiment provides a BIM-based traffic control method in road traffic accidents, including the following steps:
[0064] Step A: Establish a structural information model (BIM model) corresponding to the road project.
[0065] Step B: After a traffic accident occurs on the road, record the accident type and cause of the road traffic accident in the BIM model. According to the actual size of the accident area, in the BIM model, select a frame on the road model plan or input a certain vertex The coordinates, width and length determine the rectangular accident area in the BIM model, where the length of the accident area is H 1 , the width of the accident region is B 1 .
[0066] Step C: Determine the work area: Determine the length and width of the work area according to the length and width of the rectangular accident area, where the len...
