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...

Abstract

The invention discloses a BIM-based traffic control method in road traffic accidents, which includes establishing a BIM model corresponding to road engineering; recording the type of accident and the cause of the accident in the BIM model, and determining the rectangular accident area in the BIM model; according to the rectangular accident area Determine the length and width of the working area; determine the closed lane according to the number of lanes covered by the working area; automatically generate the vehicle parking area in the BIM model; determine the location of the vehicle parking area according to the closed lane; identify the warning area in the BIM model , the length of the upstream transition zone, the buffer zone, the downstream transition zone and the termination zone; determine the placement position of the sign and the cone barrel, and automatically generate it in the BIM model; the present invention combines BIM technology to visually display the position of the accident area on the road section, Scientifically and rationally arrange the scope of the traffic control area, reasonably place signs and cones, greatly improve efficiency, and prevent secondary traffic accidents.

Description

technical field [0001] The invention relates to the field of road traffic control, in particular to a BIM-based traffic control method in road traffic accidents. Background technique [0002] With the rapid development of the domestic economy and the continuous advancement of urbanization, motor vehicles have entered tens of millions, and the number of urban motor vehicles has increased rapidly. Even though the domestic road mileage has ranked first in the world, road traffic accidents still occur frequently, endangering citizens' lives and property Safety. After the accident, it is difficult for law enforcement officers and other corresponding personnel to make a scientific and reasonable planning of the traffic control area in a timely manner. Unreasonable traffic signs and placement of cones are more likely to cause secondary traffic accidents. [0003] BIM technology translation is a building information modeling technology. By establishing a three-dimensional model of ...
