Research on the healthcare travel behavior of the elderly in urban and suburban perspectives
城区和郊区视角下老年人就医出行行为决策研究

摘要

近年来，随着人民生活水平不断提高，健康需求日益增长，但珠海市卫生资源布局不合理、偏僻地区服务能力薄弱等问题仍比较突出。为深入探讨城区与郊区老年人利用公交系统就医出行的行为决策机制及其实际可达性，本文创新性地融合了老年人的公交出行动向与公交实时运营信息，构建了一个能够准确反映老年人公交出行特征的出行链模型。基于这一模型，我们进一步研发了一种针对老年人就医活动的出行链识别技术，该技术能够精确捕捉老年人实际的就医出行需求及其时间分布特征。此外，我们还整合了公交实时到站数据，以动态方式展现了公交服务效率对就医可达性的实际影响。本文的研究成果不仅为优化老年人的公交就医出行策略提供了科学依据，同时也为提升城市公共交通系统的适老化水平、促进医疗资源的均衡分布与高效利用提供了方向。

Abstract

In recent years, as people's living standards have risen, the demand for health care has increased. However, issues like an unreasonable distribution of health resources and insufficient service capacity in remote areas of Zhuhai City remain significant challenges. To delve deeper into the decision-making processes and actual accessibility of elderly individuals in urban and suburban areas when utilizing public transportation for medical purposes, this study innovatively combines the movement patterns of elderly passengers with real-time bus operation data, developing a travel chain model that accurately characterizes their transportation needs. Building on this model, we have developed a travel chain recognition technology tailored to elderly medical activities, capable of precisely capturing their actual medical travel needs and the characteristics of their temporal distribution. Additionally, by integrating real-time bus arrival data, we dynamically illustrate the impact of bus service efficiency on medical accessibility. The findings of this study not only offer a scientific foundation for optimizing public transportation strategies for elderly medical travel but also guide efforts to enhance the adaptability of urban public transportation systems to aging populations and promote a balanced and efficient distribution of medical resources.
