However, in the prior art, the drawings of various traffic connection facility planning schemes are not expressed intuitively enough in display, and the reporting and the opinion solicitation of the planning schemes can be carried out only in the forms of two-dimensional plane drawings, reporting slides and the like. The solicited opinion objects need to have a certain planning knowledge graph base, so that the scope of the solicited opinion objects of the planning scheme is limited, and peripheral residents who actually use the connection facilities in the future cannot participate in evaluation in the planning stage. Meanwhile, the achievement display form is not visual, interactivity is lacked, planning idea and design details are difficult to convey in a two-dimensional plane drawing, and the problem that the planning scheme is inconsistent in landing and idea is indirectly caused.
