Optimizing Urban Transportation Resilience Through Nature-Based Solutions

Abstract: Urban transportation faces significant challenges, including reducing greenhouse gas (GHG) emissions and adapting to climate change. In response, Nature-based Solutions (NbS) provide a promising approach to enhance the resilience and sustainability of transportation infrastructure. This paper examines the integration of NbS in the transportation sector, focusing on strategies such as roadside vegetation, green corridors, and permeable pavements. These strategies aim to address urban heat, improve air quality, and strengthen the resilience of infrastructure. These interventions enhance the aesthetic appeal of urban environments and offer functional benefits. The study utilizes a multi-method approach that combines Smart Urban Design (SUD) and AirSUSTAIN frameworks with advanced transportation modeling to evaluate their effectiveness. Simulation models are employed to analyze traffic flow and quantify potential reductions in GHG emissions linked to incorporating green infrastructure. Additionally, the research examines emissions reductions from active transportation modes and electric vehicle infrastructure, providing insights into how NbS can align with climate goals. The findings are represented using mapping techniques, allowing for spatial visualization of NbS impacts and identifying optimal areas for implementation. By quantifying potential GHG reductions from green infrastructure and electric vehicle networks, the research demonstrates that NbS can significantly lower emissions by promoting active transportation modes such as walking and cycling. The study also highlights the co-benefits of NbS, such as improvements in public health, while addressing critical issues of equity and access in urban transportation. Ultimately, this research provides actionable insights for urban planners and policymakers, emphasizing the scalability of NbS in creating resilient and sustainable transportation systems and contributing to a broader understanding of sustainable urban adaptation strategies.
