Road model rapid generation method based on safety evaluation

The invention relates to the technical field of road model design, in particular to a road model rapid generation method based on safety evaluation. Comprising the following steps that S1, a two-dimensional data template is established, and the two-dimensional data template comprises a plane file, a longitudinal section file, an ultrahigh file, a width file and a control file; s2, the program automatically generates a plane line shape according to different line shapes and corresponding parameters, and control points corresponding to the different line shapes are connected and transited to form a plane route model; s3, adjusting the plane route model according to the elevation parameters in the longitudinal section file to generate a three-dimensional route model; s4, automatically arranging a bridge, a tunnel and a roadbed according to control file parameters, and generating a final three-dimensional road model; a three-dimensional road model is rapidly established by importing a traditional two-dimensional
