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… Read More

Mobility and Accessibility Resilience of Transportation Infrastructures

David Yang
The objective is to address practical challenges related to mobility and accessibility following natural disasters. The anticipated outcome of this project will be to provide actionable insights and solutions that can be implemented in real-world transportation systems. By leveraging the available data from state DOTs and applying analytical techniques, our research will provide valuable insights and recommendations that can be readily implemented by transportation practitioners and… Read More
