Impacts of the new Réseau Express Métropolitain (REM) on mobility, health and equity: A pre-post intervention study

2016年，魁北克储蓄与安置中心(CDPQ)宣布计划建造 Réseau Express métropolitain(REM)，一个价值63亿美元的最先进的公共交通项目 这将通过频繁的铁路将许多郊区和机场与蒙特利尔市中心连接起来 服务。这项计划预计将影响蒙特利尔大都会的所有居民。 不同规模和不同方式的区域。这项研究项目将集中在 衡量这样的重大基础设施项目对健康、社会、 所有蒙特利尔居民的环境、经济、身体和心理健康， 施工前、施工中、施工后。这是一个史无前例的学习 在加拿大范围内，这种规模的重大公共交通项目。上一次少校 如此规模的公共交通项目建于20世纪70年代。它将教给我们的教训是 特别及时。甚至在REM完成之前，地区和省级官员就已经 已经在讨论扩张问题了。与此同时，联邦政府承诺 支持加拿大各地的类似项目，作为改善公平和打击 气候危机。据我们所知，还没有计划进行全面的研究来充分评估 REM可能对旅行行为和公众健康产生深远影响。几个部分 的REM已经在建设中，并计划在2021年开放。对他人的建设 还没有开始，给了我们一个短暂的窗口来进行研究，以衡量REM如何 在开发和运营的不同阶段都能感受到影响。最终，这项研究将 帮助政策制定者和规划者在更知情的情况下做出关于主要公众的决策 投资改善加拿大人的健康和福利。

In 2016, the Caisse de dépôt et placement du Québec (CDPQ) announced plans to build the Réseau express métropolitain (REM), a state-of-the-art, $6.3 billion public transport project that will link numerous suburbsand the airportto downtown Montreal with frequent rail service. The undertaking is expected to impact all residents of the Montreal metropolitan region at various scales and in various ways. This research project will concentrate on measuring the impacts of such major infrastructure project on the health, social, environmental, economic, physical, and psychological wellbeing of all Montreal residents, before, during and after the construction. This is an unprecedented opportunity to study a major public transport project of this scale in the Canadian context. The last time a major public transport project of this size was built in the 1970s. The lessons it will teach are particularly timely. Even before the REM's completion, regional and provincial officials are already discussing expansions. At the same time, the federal government is pledging to support similar projects across Canada as part of its efforts to improve equity and combat the climate crisis. To our knowledge, no comprehensive study has been planned to fully assess the REM's possibly profound impacts on travel behaviour and public health. Several sections of the REM are already under construction and slated to open in 2021. Construction on others has yet to begin, giving us a brief window to conduct research to measure how the REM's impact is felt at various stages of development and operation. In the end, the research will help policymakers and planners make better-informed decisions about major public investments to improve Canadians health and welfare.
