客流仿真模拟在城市轨道交通车站改造中的应用简

通过在重庆轨道交通3号线观音桥站改造设计过程中引入客流仿真模拟技术，对车站改造前后的客流密度分布、出入口疏散时间等进行仿真模拟，论证了观音桥站增建1个小站厅及2个出入口后，站内客流拥挤程度降低，出入口整体疏散时间减少，车站疏散能力明显提高。

Passenger Flow Simulation Used in Transit Station Renovation

By introducing passenger flow simulation technology in design process of Guanyinqiao station renovation on Chongqing line 3, the paper carries out simulation of traffic flow density distribution before and after the reconstruction of station, entrance and exit evacuation simulation time, and it visually demonstrates after a new small station hall, two exit and entrance built at Guanyinqiao station it has reduced crowding of station passengers, reduced the entrance and exit evacuation time significantly and improved station evacuate capacity. It helps to rationally improve station design in reconstruction so as to reduce investment.
