Abstract:The escalating impacts of climate change and rapid urbanization pose significant challenges to non-motorized transportation facilities (NMTFs) and low-income communities (LICs) in Delaware. This project aims to assess the negative impacts of climate change, including sea level rise (SLR), increasing temperatures, and changes in precipitation patterns, on NMTFs and LICs using Delaware as a case study. We first use GIS analysis to evaluate the vulnerability of LICS and NMTFs under different SLR scenarios ranging from 1 to 7 feet. We then explore the implications of temperature rises, projected to increase by 2.5 to 4.5 degrees Fahrenheit by 2050 (Delaware’s Climate Impacts, 2023), on transportation modes and accessibility, focusing on vulnerable populations reliant on walking, cycling, and micro-mobility options. Our analysis is informed by recent studies that indicate rising temperatures tend to promote non-motorized transportation modes, although extreme heat events can lead to infrastructure damage, service disruptions, and safety concerns (Böcker, Dijst, & Faber, 2016; Zhai et al., 2019). We also examine the impacts of urbanization trends on LICs and NMTFs, addressing changes in transportation mode usage and the consequences of housing market dynamics on low-income residents. The project aims to identify how climate change and urbanization affect transportation equity and to inform planning strategies that mitigate these impacts.
