Connecting people to places: spatiotemporal analysis of transit supply using travel-time cubes
Steven Farber
Transit planning traditionally emphasizes the spatial dimension of accessibility; networks are built to bridge locations in the city with the assumption that the provision of spatial connectivity is equivalent to providing people with access to their destinations. However, often underrepresented in transit analyses, is that travel time, not network proximity, is the fundamental unit of influence over people's travel behavior. It is the time lost in travel that drives whether or not people will…

Urban Transportation System Flood Vulnerability Assessment with Special Reference to Low Income and Minority Neighborhoods
Courtney Crosson
Short-term flooding from extreme storm events poses a serious transportation challenge in U.S. cities. This problem—which is anticipated to grow over the next century with our global climate crisis—is often hardest on vulnerable populations, including low-income and minority neighborhoods. The latest report from the National Institute for Transportation and Communities (NITC), led by Courtney Crosson of University of Arizona (UA), advances national research methods for assessing flood…
