Few measures of healthcare accessibility have considered multiple transportation modes when people seek healthcare. Based on the framework of the 2 Step Floating Catchment Area Method (2SFCAM), we proposed an innovative method to incorporate transportation modes into the accessibility estimation. Taking Florida, USA, as a study area, we illustrated the implementation of the multi-mode 2SFCAM, and compared the accessibility estimates with those from the traditional single-mode 2SFCAM. The results suggest that the multi-modal method, by accounting for heterogeneity in populations, provides more realistic accessibility estimations, and thus offers a better guidance for policy makers to mitigate health inequity issues.
当人们寻求医疗保健时，很少有医疗可及性的衡量标准考虑多种交通方式。基于两步浮动捕获区域方法（2SFCAM）的框架，我们提出了一种创新的方法，将交通方式纳入可达性估计中。以美国佛罗里达州为例，我们说明了多模式 2SFCAM 的实施，并将可达性估计与传统的单模式 2SFCAM 的估计进行了比较。结果表明，多模式方法通过考虑人群的异质性，提供了更现实的可达性估计，从而为政策制定者提供了更好的指导，以减轻健康不平等问题。
