The reasonable setting of guides can directly improve the evacuation capacity in the subway station. The important role of guide assignment scheme and evacuation path planning of guided passengers is particularly prominent. Considering the distribution of passengers in the station, one contribution is that an assignment scheme of the initial number and location of guides is firstly established based on Gaussian mixture model and cost function method, so as to increase the guidance range and reduce the waste of human resources. Another contribution is that a multi-objective optimization model is developed for guide path planning and NSGA-II method is used to find the optimal solution, which could help avoiding the evacuation bottlenecks in advance. Massmotion embedded with social force model and minimum cost model is adopted to simulate the movement of people, which is verified by the independent sample $t$-test in this paper. Evacuation experiments under the random distribution of passengers are carried out to demonstrate the significance of the proposed guidance method. The results indicate that the total evacuation efficiency can be improved by about 13% in the scenario with guides, and the passengers’ choice of stairs/escalators is more balanced. Moreover, passengers induced by different guides can avoid reaching the same evacuation node at the same time window, which alleviates the pressure of nodes. The results could provide theoretical support for passenger safety management and even improve the service level of stations.

导板的合理设置可以直接提高地铁站的疏散能力。导员分配方案和导员疏散路径规划的重要作用尤为突出。考虑到站内乘客分布，一个贡献是首先基于高斯混合模型和成本函数法建立了引导员初始数量和位置的分配方案，以增加引导范围，减少人力浪费资源。另一个贡献是开发了用于引导路径规划的多目标优化模型，并使用 NSGA-II 方法找到最优解，这有助于提前避免疏散瓶颈。$吨$-在本文中进行测试。进行了乘客随机分布下的疏散实验，以证明所提出的引导方法的重要性。结果表明，在有向导的场景下，总疏散效率可提高约13%，乘客对楼梯/扶梯的选择更加均衡。此外，不同导游引导的乘客可以避免在同一时间窗口到达同一个疏散节点，从而缓解节点压力。研究结果可为旅客安全管理提供理论支持，甚至提高车站服务水平。
