Line Positioning Scheme Optimization of Xi′an Metro Line 16

Multiple large passenger flow points exist in one corridor in the first phase project of Xi′an Metro Line 16. With respect to the regional planning, problems of line positioning scheme in original planning are analyzed, and optimization scheme is proposed with outcome estimation. Due to the adjustment of regional planning and positioning of the Epanggong Railway Station, the section between Zhangwangqu station and Ketong No.3 Rd station in the first phase project of Xi′an Metro Line 16 deviated from the new city center. Therefore optimization scheme adjusts the line to Fuxing Avenue. The criteria for choosing the metro line positioning scheme focuses more on planning and passenger flow demand analysis, on top of which is the technical and economical analysis of project engineering. Despite the increased construction cost and engineering difficulty of the selected optimization scheme, it has enhanced the adaptability to regional planning. It is the more reasonable scheme because the passenger flow attraction effect is obvious and performance is better overall.
