摘要: 针对现有城市医疗服务可达性分析方法未考虑就医偏好,导致测算结果与居民实际感受相差较大的问题,本文提出了一种顾及时间和距离成本偏好的医疗服务时空可达性分析方法,并以武汉市中心城区为例进行了分析。试验结果表明,研究方法充分利用交通路况,兼顾了交通距离和通行时间对就医选择的影响,距离偏好在新方法中作用显著。该方法一方面可以体现不同时刻可达性差异,另一方面又强调了居民就医的时间和距离成本偏好,相比单一的时间或距离成本更具优势,分析结果更符合现实。

Abstract: In view of the problem that the existing urban medical service accessibility analysis methods do not consider the medical preference,resulting in a large difference between the calculation results and the actual feelings of residents,this paper proposes a medical service spatio-temporal accessibility analysis method considering the medical time cost and distance cost preference,and takes the central urban area of Wuhan as an example. The experimental results show that research methods fully consider the impact of real traffic conditions on accessibility,and comprehensively consider the impact of traffic distance and travel time on residents' medical choice. At the same time,distance preference has a significant impact on the analysis results. When considering the actual road conditions,the accessibility shows a significant dynamic change trend in a day. On one hand,this method can reflect the difference of accessibility at different times. On the other hand,it emphasizes the preference of residents' time cost and distance cost. Compared with single time cost or distance cost,it has significant changes,and the analysis results are more in line with the reality.
