Efficient evacuation planning is important for quickly navigating people to shelters during and after an earthquake. Geographical information systems are often used to plan routes that minimize the distance people must walk to reach shelters, but this approach ignores the risk of exposure to hazards such as collapsing buildings. We demonstrate evacuation route assignment approaches that consider both hazard exposure and walking distance, by estimating building collapse hazard zones and incorporating them as travel costs when traversing road networks. We apply our methods to a scenario simulating the 2016 Gyeongju earthquake in South Korea, using the floating population distribution as estimated by a mobile phone network provider. Our results show that balanced routing would allow evacuees to avoid the riskiest districts while walking reasonable distances to open shelters. We discuss the feasibility of the model for balancing both safety and expediency in evacuation route planning.

在地震灾害疏散路线规划中平衡危险暴露与步行距离

有效的疏散计划对于在地震发生期间及发生后迅速将人们带到避难所至关重要。地理信息系统通常用于规划路线，以使人们必须步行才能到达避难所的距离最小化，但是这种方法忽略了暴露于诸如倒塌建筑物等危险的风险。我们通过估算建筑物倒塌危险区域并将其作为穿越道路网络时的旅行费用，来说明同时考虑危险暴露和步行距离的疏散路线分配方法。我们使用移动电话网络提供商估算的流动人口分布，将我们的方法应用于模拟2016年韩国庆州地震的场景。我们的结果表明，均衡的路线安排可以使撤离人员避开最危险的地区，同时步行一定距离到达避难所。我们讨论了在疏散路线规划中平衡安全性和权宜性的模型的可行性。
