Physical Exposure and Social Sensitivity Estimating Sea Level Rise Impacts to Transportation through Vulnerability Assessment and Social Media Analysis

Sea level rise, as one of the most wide-spread and important climate change factors, has become a pressing threat to transportation infrastructures, especially in coastal region. It is particularly a challenge for Hawaii given the geographic and topographic situation of these islands. While many research have been conducted to assess the potential impacts and physical vulnerability of transportation network to sea level rise, it is often difficult to validate the results due to the lack of empirical data. In recent years, social media provides a new opportunity to collect the perishable hazards data, identify the affected areas, and provide useful information for disaster management. Its value in capturing the views, needs, and experiences of the travelling public to support the development of long-term transport policy and transport planning has been acknowledged. However, despite its potential, social media has yet been applied to study the impacts of long-term, gradual hazards on transportation, indicating both a gap and an opportunity. This project proposes to combine traditional transportation vulnerability assessments with social media analysis to assess the potential impacts of sea level rise on transportation and propose adaptation suggestions. Through the examination of past extreme coastal flooding events in Honolulu, it demonstrates how twitter data, community mapping, and transportation vulnerability analysis could complement each other to understand the impacts of sea level rise on transportation from different perspectives and at different geographical scales.
