David Levinson points out to this great presentation by Kevin Webb talking about Modeling Transport accessibility with open data. Kevin and his team at Conveyal combine GTFS data, OpenStreetMap and OpenTripPlanner Analyst to make simple and yet sophisticated analysis of transport accessibility.
I feel very enthusiastic about Kevin's presentation because part of my PhD thesis will be closely connected to some of the questions he raised. In one of my papers, I will analyze the distributional aspects of how the addition of new transport infrastructure/services in Rio de Janeiro (particularity related to mega events) will impact urban accessibility across the metropolitan area. I'll post some updates about my PhD research in the near future as I
suffer to make some progress on it.
There are dozens of other thoughts, papers and Links on GTFS and transport accessibility I would like to share here (including the research conducted by Andrew Owen, D. Levinson and other researchers), but I'm sure we will have many more posts to do this in the near future.
