Traditional two-dimensional maps and data management methods can no longer meet the needs of modern highway management, especially in terms of data integration, information sharing and visualization.

[0003] In recent years, the informatization of highway management has become an inevitable trend in the development of the industry. The traditional highway management method has problems such as data dispersion and information islands, resulting in low management efficiency.

When the route direction is upward, the position of point P1 is the starting pile number position, and is on the left side of the first lane on the right side of the road. The position of point P2 is the starting pile number position, and is on the right side of the second lane on the right side of the road. The position of point P3 is the ending pile number position, and is on the right side of the second lane on the right side of the road. The position of point P4 is the ending pile number position, and is on the left side of the first lane on the right side of the road. S7-2-4. According to the positions of the four points P1, P2, P3, and P4 determined in S7-2-2 and S7-2-3, use the general procedure of S5 to obtain the coordinates and elevations of the four points.

8. The method for integrating highway construction, management and maintenance data and performing three-dimensional display according to claim 1, characterized in that: The display of highway disease data in the three-dimensional model space in S8 includes the following steps: S8-1, reading the highway disease pile number and disease data imported in S4-2; S8-2, using the general procedure in S5 to obtain the coordinates and elevations of the highway disease; S8-3, loading the highway disease icon and disease number in the three-dimensional model space according to the coordinates and elevations obtained in S8-2; S8-4. Use the mouse to click on the disease icon generated in S8-3 to view more detailed disease information.

9. The method for integrating highway construction, management and maintenance data and performing three-dimensional display according to claim 1, characterized in that: The display of the pavement maintenance data in the three-dimensional model space in S9 includes the following steps: S9-1, reading the pavement maintenance data imported in S4-3; S9-2, using the general procedure in S5 to obtain the coordinates and elevations of the pavement maintenance; S9-3, loading the pavement maintenance icon and maintenance number in the three-dimensional model space according to the coordinates and elevations obtained in S9-2; S9-4. Use the mouse to click the pavement maintenance icon generated in step S9-3 to view more detailed maintenance operation information.
