本文提出了一种新的方法来分析潜在的救护车服务的可及性相结合的需求覆盖率和潜在的服务能力与救护车覆盖率。基于地理信息系统的空间分析将有助于救护车服务规划者和设计者根据模拟的随机事件评估和提供合理的服务范围。建议的分析模型进行了比较，以重力为基础的两步浮动汇水面积的方法。研究发现，所提出的模型可以有效地识别覆盖不足和重叠的救护车服务覆盖，以提高服务质量，及时性和效率。空间可达性和服务能力与地理空间随机事件的识别表明，该模型能够规划合理的救护车服务覆盖范围考虑家庭和旅行时间。该模型可以应用于区域和全州范围的覆盖计划，以帮助解释这些计划。
This paper proposes a novel approach to analyze potential accessibility to ambulance services by combining the demand-covered-ratio and potential serviceability with the ambulance-covering-ratio. A Geographic Information System (GIS)-based spatial analysis will assist ambulance service planners and designers to assess and provide rational service coverage based on simulated random incidents. The proposed analytical model is compared to the gravity-based two-step floating catchment area method. The study found that the proposed model could efficiently identify under-covered and overlapped ambulance service coverage to improve service quality, timeliness, and efficiency. The spatial accessibility and serviceability identified with geospatial random events show that the model is able to plan rational ambulance service coverage in consideration of households and travel time. The model can be applied to both regional and statewide coverage plans to aid the interpretation of those plans.
