[0002] Currently, in the field of modern road and bridge engineering construction, with the continuous expansion and upgrading of transportation networks, the scale and complexity of road and bridge construction are increasing day by day. Among them, for road and bridge construction scenarios with left and right lane structures, safety protection and on-site management during construction have become crucial aspects.

[0003] In existing technologies, there is still a lack of efficient and standardized traffic solutions for cross-passages in the middle area of ​​the left and right lanes of road and bridge, which serve as crucial passageways for subsequent traffic separation and the transfer of construction personnel and materials.
