交通枢纽应急疏散仿真和智能指示灯设计研究

Study of emergency evacuation simulation and intelligent indicator lamp design for transportation hubs

针对大型综合交通枢纽在火灾情况下人员能否及时准确逃生的问题,文章采用人员疏散仿真模拟软件Pathfinder研究了某枢纽在不同火灾场景下应急疏散过程,获得了人员逃生疏散时间,并根据不同的疏散场景优化人员应急疏散路线,最后提出可以依据不同火灾疏散场景智能变换指示方向、显示距离等较多疏散信息的优化指示灯系统,向疏散人群传达应急疏散线路,以提高乘客的疏散效率和减少人员伤亡。

To study whether people can escape in time in case of catching fire in the transportation hub, the personnel emergency evacuation in a transportation hub under different fire scenarios is simulated by applying the dynamic evacuation simulation software Pathfinder. Personnel escape evacuation time under different fire scenarios is obtained, and according to the different evacuation scenarios, the personnel emergency evacuation route is optimized. Finally, the optimized indicator lamp system, which can intelligently transform the evacu- ation information including the direction and distance according to different fire evacuation scenarios, is put forward. Dynamic emergency evacuation routes are displayed in order to improve the passenger evacuation ef- ficiency and reduce casualties to the greatest extent.
