线网指挥中心是各城市轨道交通网络化运营深入发展后的必然选择，是网络运营协调、信息互联互通和应急处置联动的核心机构。在借鉴国内各典型城市轨道交通网络运营管理的经验基础上，基于苏州轨道交通在运营安全的严峻性、设备制式的多元性、线网结构的复杂性、运行组织的多样性、网络客流的波动性、出行特征的异质性、交通衔接的多重性等方面的运营需求，对线网指挥中心的运营职能进行优化。最后以网络客流分析为例，梳理业务流程并提出优化建议，为网络客流的精细化管控提供支撑。

The construction of the network control center is the inevitable choice after the in-depth development of urban rail transit network operation. It is the core organization for network operation coordination, information interconnection, and emergency linkage. Based on the experience of domestic typical urban rail transit network operation and management, and the operational requirements of Suzhou Rail Transit such as the severity of operational safety, the diversity of equipment system, the complexity of line network structure, the diversity of operation organization, the fluctuation of network passenger flow, the heterogeneity of travel characteristic, and the multiplicity of traffic connection, the operation functions of Suzhou Rail Transit NCC (Network Control Center) are optimized. Finally, taking the network passenger flow analysis as an example, the business process and optimization suggestions are put forward, which could provide support for the delicacy management and control of network passenger flow.
