Hurricanes lead to substantial infrastructure system damages, such as roadway closures and power outages, in the US annually, especially in states like Florida. As such, this paper aimed to assess the impacts of Hurricane Hermine (2016) and Hurricane Michael (2018) on the City of Tallahassee, the capital of Florida, via exploratory spatial and statistical analyses on power outages and roadway closures. First, a geographical information systems (GIS)-based spatial analysis was conducted to explore the power outages and roadway closure patterns in the city including kernel density estimation (KDE) and density ratio difference (DRD) methods. In order to provide a more detailed assessment on which population segments were more affected, a second step included a statistical analysis to identify the relationships between demographic- and socioeconomic-related variables and the magnitude of power outages and roadway closures caused by these hurricanes. The results indicate that the high-risk locations for roadway closures showed different patterns, whereas power outages seemed to have similar spatial patterns for the hurricanes. The findings of this study can provide useful insights and information for city officials to identify the most vulnerable regions which are under the risk of disruption. This can lead to better infrastructure plans and policies.

Sustainability transitions require that sustainable innovations develop and scale-up. Two promising approaches contribute to this purpose. Design thinking (DT) focuses on the creative development of sustainable innovations to achieve desirable, feasible and viable products. Strategic niche management (SNM) addresses how sustainable innovations should be deployed to the market. At first sight, these concepts seem to pursue a complementary mission, yet, academic literature has not explicitly addressed their complementary nature. Therefore, this paper addresses this gap by reviewing, proposing and empirically exploring the merits of SNM and how these can be used in DT through a workshop to increase successful market implementation of sustainable innovations. The study finds that SNM potentially helps the DT design process to (1) change market preconditions for the design, (2) create a protected niche for development, (3) establish a (long term) commercial viability, and (4) create an innovation development plan through definition of a set of testable propositions. The paper concludes that the inclusion of SNM into DT substantially increases the preparedness of an innovation team for a successful market implementation of sustainable innovations and coins the term 'Design to Market Thinking' for the integrated use of SNM in DT.
