[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0042] as attached Figures 2 to 6 As shown, a design method for improving the visual environment of the bridge-tunnel connection section of a mountainous expressway. At the exit of a low-illumination expressway tunnel, the lower edge of the curb stone at the exit of the tunnel, the red and white marking line 7 on the maintenance road plane, and the raised road signs 6 on the roadside road surface are set. , the distance between the lower edge of adjacent curbs and the red and white marking lines on the plane of the maintenance road is 1.5m~3m, which constitutes a spatial high-frequency visual information flow to enhance the driver's sense of speed;
[0043] Set the tunnel exit side wall facade marking line 5 and the side wall double-layer contour mark on the 150m side wall of the tunnel exit section. The distance between the side wall double-layer contour ma...
