摘要

在人口老龄化日益严重的城市居民区，首英里和最后一英里的交通是一个紧迫的城市问题。需求响应型交通（DRT）作为解决城市问题的一种手段正受到越来越多的关注。本研究旨在阐明DRT对居民日均步行步数的影响。本研究以仙佛新城DRT示范工程为案例进行分析。方法采用队列研究设计，参与者从当地智能手机应用程序“Health-Smart-Senboku”的用户中招募。参与者接受了一份在线调查问卷。倾向评分匹配用于估计潜在混杂因素的影响。随后，对DRT用户组和非用户组的日常步行步数变化进行了差异中差异分析。结果DRT手术可使患者平均日步行步数增加628.16 [95% ci]。−231.37 ~ 1487.70,p = 0.009]步/天。这些结果很有趣，因为在DRT操作期间，DRT用户组的人比非DRT用户组的人走的步数少，但在DRT操作期间走的步数更多，增加到与非DRT用户组相同的水平。此外，被广泛接受的健康相关生活质量评估指标EQ-5D-5L平均评分在DRT使用者组（0.88）显著高于非DRT使用者组（0.93），差异有5%的显著性水平（p = 0.033）。结果还表明，DRT用户组乘坐私家车的频率明显低于非DRT用户组。然而，在DRT用户和非用户组的驾驶执照持有之间没有显着差异。结论DRT手术对有健康相关问题且不能使用私家车的人群行走有促进作用。这些发现意义重大，因为它们表明DRT通过增加每日步数对幸福感产生社会影响。

Effects of demand-responsive transport on daily waking steps in Senboku New-Town: A cohort study using propensity score matching

Introduction

First- and last-mile mobility is an urgent urban issue in urban residential areas with increasingly older populations. Demand-responsive transport (DRT) is gaining attention as a means to resolve the urban issue. This study aimed to clarify the effect of DRT on residents' average daily walking steps. This study analyzed the case using the DRT demonstration project in Senboku New Town.

Method

A cohort study design was employed, and participants were recruited from users of a local smartphone application called “Health-Smart-Senboku.” An online questionnaire was administered to the participants. Propensity score matching was used to estimate the effects of potential confounding factors. Subsequently, a difference-in-differences analysis was performed on the changes in daily walking steps of DRT user and non-user groups.

Result

The results indicated that DRT operation significantly increased the average daily walking steps by 628.16 [95%C.I. −231.37 to 1487.70, p = 0.009] steps/day. These results are interesting because people in the DRT user group walked fewer steps than people in the DRT non-user group before the DRT operation period but walked more steps during the DRT operation period, increasing to the same level as the DRT non-user group. Furthermore, the average EQ-5D-5L score, a widely accepted index to assess health-related quality of life, is significantly higher in DRT user group (0.88) than in DRT non-user group (0.93) at a 5% significant level (p = 0.033). The results also indicated that the DRT user group took a private car significantly less often than the DRT non-user group. However, there were no significant differences between driver’s license possession in the DRT user and non-user groups.

Conclusion

This study concluded that DRT operation promoted walking among those with health-related problems who could not use private cars. These findings are significant because they indicate the social impact of DRT on well-being by increasing daily step counts.
