Transport Accessibility of Community Health Service Based on the Point-of-Interests(POIs) Data: A Case Study of Shanghai

社区卫生服务中心是我国最基本的医疗服务设施,其在空间上的分布代表着公共卫生服务设施的公平性。本文以百度兴趣点(POI)数据作为数据获取手段,有助于短时、且大量收集数据,并通过比较小汽车与常规公交两种出行方式的可达性,评价上海市社区卫生服务中心的布局合理性。结果显示,在城市空间上卫生服务中心的公交可达性远低于小汽车,对于使用公交出行的人群并不公平,未来在进行公交线路调整时,应该更多地考虑公交公平性,而非一味关注运行效率。

As the primary medical service facility in China, Community Health Service should treat all citizens equally. Understanding its location may help us to evaluate the equity of public medical resource. This paper was aims to find out the rationality of the Community Health Service in Shanghai which is traveled by two different transport modes, automobile and general bus. Their accessibilities were calculated and compared based on the Point- of-Interests （POIs） data, which can be more easily and widely collected via online applications compared with tradition surveys. In addition, although accessibilities varied in different areas, the accessibility of general bus is significantly lower than the automobile. The results may benefit the local government to optimize public transport network considering the equity, rather than the efficiency only.
