In zone-based evacuation planning, the region to evacuate is divided into zones, and each zone must be assigned a path to safety and departure times along the path. Zone-based evacuations are highly desirable in practice because they allow emergency services to communicate evacuation orders and to control the evacuation more precisely. Zone-based evacuations may also be combined with contraflows (to maximize the network capacities) and may impose additional constraints on the evacuation path (e,g., path convergence) and the departure times (e.g., non-preemption). This paper synthesizes existing models and algorithms for large-scale zone-based evacuation planning and complements them with some new ones to fill some of the gaps in the design space. Each model and algorithm is also extended to accommodate contraflows. A companion paper [13] evaluates them on a real, large-scale case study, both from a macroscopic standpoint and through microscopic simulations under a variety of assumptions.

大规模区域疏散规划——第一部分:模型和算法

在基于区域的疏散规划中,要疏散的区域被划分为多个区域,每个区域必须沿着路径分配一条安全路径和出发时间。在实践中非常需要基于区域的疏散,因为它们允许紧急服务传达疏散命令并更精确地控制疏散。基于区域的疏散也可以与逆流相结合(以最大化网络容量),并且可以对疏散路径(例如,路径收敛)和出发时间(例如,非抢占)施加额外的约束。本文综合了现有的大规模区域疏散规划模型和算法,并用一些新的模型和算法对其进行了补充,以填补设计空间中的一些空白。每个模型和算法也被扩展以适应逆流。
