## Computing Service Areas of Fire Protection Facilities Based on the Space-time Allocation Model in GIS

• 摘要: 基于时空分配组合方法,综合考虑服务时间在主干道路和街区内分配的各种情形,探讨了符合实际需求的消防站点服务范围计算方法。提出了基于多个独立指标的评价消防设施布局方案的方法,对消防规划方案进行评价。最后以武汉市武昌区为例对所提出方法进行了实验,实验结果也验证了该方法的可行性和合理性。

Abstract: Spatial arrangement is a key factor for layout optimization of fire protection facilities.The path analysis based on the proposed space-time allocation model provides a solid measure for the layout optimization. It is often simplified by using a circular area based on the facility location to represent a buffer zone or simply consider only the road segments that a fire engine has to travel.In this research,we introduce a hybrid measurement considering both travel time on the main roads and the inner part of a neighborhood for layout optimization of fire protection facilities.Furthermore,some indices are introduced to measure the service level of spatial arrangement of fire protection facilities quantitatively.Finally,some testing results are produced and presented by using modeling techniques in ArcGIS software and they show that the proposed approach is much more appropriate than the two simplified versions.
