摘要
为有效描述要素空间分布,结合面向建筑的地理信息系统(Building GIS)与行为规则库,构建了人员疏散行为模型。通过CAD数据的语义解析,描述建筑空间单元连通性等特征。应用GIS技术构建疏散网络,实时分析建筑场景内要素分布特征及行为规律。在此基础上为智能体设计行为规则库,描述疏散中人员的行为意图与策略。结合应用实例,与实测数据和building EXODUS模拟结果进行了对比验证。结果表明:该模型能够表现建筑场景的人员疏散进程,反映出口疏散效率随时间的变化规律。
Spatial distributions of variables were properly described based on a developed behavioral model for evacuation using Building GIS and behavioral rule base with CAD data parsed to capture building features,including the internal connectivity.An evacuation network was established based on GIS to analyze variable distributions and behaviors in real time.A behavioral rule base was then designed accordingly to specify intensions and strategies for agents.A case study was conducted to validate the model by comparing with the buildingEXODUS simulation results and the experimental data.The result demonstrates that the model can simulate the evacuation process in buildings and evaluate the exit evacuation efficiency varying with time.
