The invention relates to a design method of a track and the track. The design method of the track comprises the following steps of S1, building a coordinate system; S2, constructing a coordinate system model of a track car, and constructing a known model of a first track edge or a second track edge in the coordinate system; S3, conducting conversion according to the moving path of a first walkingsystem on the track car along the first track edge in the coordinate system to obtain a coordinate system model of the second track edge, or conducting conversion according to the moving path of a second walking system on the track car along the second track edge in the coordinate system to obtain a coordinate system model of the first track edge. By means of the design method, through innovativegeometric curved surface design, pulleys of the track car on a track can be always in close contact with track slide rails, it can be guaranteed that embedding of a pulley group and the track is maintained stable and consistent all the time whether the track car runs on a straight track or a bent track; the demand of the track car for steering wheels is omitted, and the mechanical structure designof the track car can be simplified.
