Community-based alternative urban transportation decarbonization pathways and co-benefits for climate resilience, air quality, health, and equity

随着市政当局制定实现零排放目标的行动计划，减少城市车辆行驶公里数（VkT）是有机会的。虽然车队电气化是过去和现在的研究和政策的重点，但脱碳交通的途径不能只关注电气化。减少VkT的机会非常重要，足以(a)减少排放，(b)减少对广泛私家车电气化的迫切需求，以及(c)在推进其他社区目标的同时提供气候适应性效益。多样化的交通选择有望增强社区的整体复原力和可持续性。该项目将推进加拿大的知识和工具，通过调查替代交通途径，为社区决策过程提供信息，以实现净零目标。本研究将开发一个综合环境评估工具，以支持以社区为基础的交通计划，旨在(a)实现基于更智能、更主动的交通选择的零排放目标；(b)从弹性、健康和宜居性的角度纳入气候导向的规划；(c)展示脱碳投资的公平效益。来自机械工程、地球与大气科学、土木工程、公共政策、城市规划和环境卫生的跨学科研究团队将为开发综合建模系统的要素做出贡献。该研究将解决社区规划和设计中的关键知识空白，以解决新兴车辆技术、多种交通方式、减排目标、大气化学反应、基础设施和服务弹性在快速变化的气候下的相互联系和权衡，并旨在确定减少健康影响、空气污染暴露差异和整体宜居性方面的共同利益。这项研究回答了这样一个问题：加拿大社区可以做些什么来大幅减少交通排放，这对于到2050年实现净零排放目标至关重要，建立行业和社区的弹性，并促进额外的社区健康和宜居性效益？

As municipalities develop action plans to meet zero-emission targets, opportunities exist to reduce urban vehicle kilometres travelled (VkT). Although fleet electrification is a focus of past and current research and policy, pathways to decarbonize mobility must not focus on electrification alone. Opportunities to reduce VkT are significant enough to (a) reduce emissions, (b) reduce the immediate need for extensive private vehicle electrification, and (c) provide climate resiliency benefits while advancing other community goals. Diversifying mobility options are expected to enhance overall community resilience and sustainability. This project will advance Canadian knowledge and tools to inform community decision-making processes to achieve net-zero objectives by investigating alternate transportation pathways. This research will develop an integrated environmental assessment tool to support community-based transportation plans that aim to (a) achieve zero-emission objectives based on smarter more active mobility options and (b) incorporate climate-oriented planning from a resilience, health, and livability perspective, and (c) showcase equitable benefits of decarbonization investment. The interdisciplinary team of researchers from mechanical engineering, earth and atmospheric science, civil engineering, public policy, urban planning, and environmental health will contribute to developing elements of the integrated modelling system. The research will address critical knowledge gaps in community planning and design for the interconnectivity of and trade-offs between emerging vehicle technologies, diverse transportation modes, emissions reduction targets, atmospheric chemical reactions, infrastructure and service resilience under a rapidly changing climate, and aim to identify co-benefits in terms of reduced health impacts, air pollution exposure disparities, and overall increased livability. This research answer the question: What can Canadian communities do to dramatically reduce the transportation emissions, crucial for achieving net-zero targets by 2050, build resilience in the sector and community, and advance additional community health and livability benefits?
