摘要

背景自行车基础设施投资支持积极交通、改善人口健康并减少健康不平等。本研究探讨了蒙特利尔自行车基础设施的变化（2011-2016 年）与人口普查区（CT）层面的物质匮乏、明显少数群体和绅士化之间的关系。方法我们的研究结果是 2011 年受保护自行车道、自行车专用道、多用途道路和街道自行车道的长度，以及 2011 年至 2016 年人口普查区层面自行车道总长度的变化。人口普查数据提供了 2011 年物质匮乏程度和有色人种比例的衡量指标，以及 2011 年至 2016 年期间 CT 是否实现了贵族化。我们使用障碍建模方法，探讨了这些县城层面的社会经济措施、城市化状况、自行车基础设施基线（2011 年）及其变化（2011-2016 年）之间的关联。我们进一步检验了这些关联是否因现有基础设施基线水平的不同而有所变化，以评估原本资源较少的地区是否受益更少或更多。结果2011年，物质匮乏程度较高或明显少数族裔比例较高的县城的自行车基础设施较少。总体而言，2011 年至 2016 年间，自行车基础设施在道路网络中的占比从 7.0% 增加到 10.9%，但在 2011 年尚未建设自行车基础设施的县城，新建自行车基础设施的可能性较低，而在有色人种比例较高的县城，新建自行车基础设施的可能性较高。2011 年至 2016 年间，与同期未进行城市化改造的低收入城市相比，不符合城市化改造条件的高收入城市中心区从新的自行车基础设施建设中获益较少。然而，在有色人种较多的城市，尤其是目前还没有自行车基础设施的城市，优先实施自行车基础设施至关重要。

Associations between gentrification, census tract-level socioeconomic status, and cycling infrastructure expansions in Montreal, Canada

Background

Cycling infrastructure investments support active transportation, improve population health, and reduce health inequities. This study examines the relationship between changes in cycling infrastructure (2011–2016) and census tract (CT)-level measures of material deprivation, visible minorities, and gentrification in Montreal.

Methods

Our outcomes are the length of protected bike lanes, cyclist-only paths, multi-use paths, and on-street bike lanes in 2011, and change in total length of bike lanes between 2011 and 2016 at the CT level. Census data provided measures of the level of material deprivation and of the percentage of visible minorities in 2011, and if a CT gentrified between 2011 and 2016. Using a hurdle modeling approach, we explore associations among these CT-level socioeconomic measures, gentrification status, baseline cycling infrastructure (2011), and its changes (2011–2016). We further tested if these associations varied depending on the baseline level of existing infrastructure, to assess if areas with originally less resources benefited less or more.

Results

In 2011, CTs with higher level of material deprivation or greater percentages of visible minorities had less cycling infrastructure. Overall, between 2011 and 2016, cycling infrastructure increased from 7.0% to 10.9% of the road network, but the implementation of new cycling infrastructure in CTs with no pre-existing cycling infrastructure in 2011 was less likely to occur in CTs with a higher percentage of visible minorities. High-income CTs that were ineligible for gentrification between 2011 and 2016 benefited less from new cycling infrastructure implementations compared to low-income CTs that were not gentrified during the same period.

Conclusion

Montreal's municipal cycling infrastructure programs did not exacerbate socioeconomic disparities in cycling infrastructure from 2011 to 2016 in CTs with pre-existing infrastructure. However, it is crucial to prioritize the implementation of cycling infrastructure in CTs with high populations of visible minorities, particularly in CTs where no cycling infrastructure currently exists.

期刊介绍： SSM - Population Health. The new online only, open access, peer reviewed journal in all areas relating Social Science research to population health. SSM - Population Health shares the same Editors-in Chief and general approach to manuscripts as its sister journal, Social Science & Medicine. The journal takes a broad approach to the field especially welcoming interdisciplinary papers from across the Social Sciences and allied areas. SSM - Population Health offers an alternative outlet for work which might not be considered, or is classed as ''out of scope'' elsewhere, and prioritizes fast peer review and publication to the benefit of authors and readers. The journal welcomes all types of paper from traditional primary research articles, replication studies, short communications, methodological studies, instrument validation, opinion pieces, literature reviews, etc. SSM - Population Health also offers the opportunity to publish special issues or sections to reflect current interest and research in topical or developing areas. The journal fully supports authors wanting to present their research in an innovative fashion though the use of multimedia formats.
