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…

V2X: Bringing Bikes into the Mix
Stephen Fickas
This project focuses on a type of transportation that is currently left out of V2X conversations: bicycling. The project demonstrates how an inexpensive system can add new functionality to existing signal controllers, giving bicyclists an efficient way to cross a controlled intersection. The system proposed and demonstrated integrates three components:
(1) a Bike Connect box that resides near the signal-controller and is connected to it,
(2) an application that runs on a Bike Connect device…
