| Abstract: | With some practical cases of Shanghai Outer Ring diamond viaduct, parallel ramp of Xujiahui Rd., South-north Viaduct, the existed traffic problems of diamond viaduct which was located in the intersection of expressway and major-minor path were analyzed. Then, three improvement ways were applied in this paper, which could meet with different construction conditions and traffic needs and supply reference for the design of expressway diamond viaduct. |
