The third chapter of my dissertation has just been released as a pre-proof (draft) over at SocArXiv. It deals with models of route choice in GTFS-based transit accessibility models and argues that such models should move away from their origins as trip-planning applications and toward more realistic approximations of human travel behaviour.
The pre-proof is available here ( DOI: 10.31235/osf.io/3r4p6 ) and will be updated there with a final version and link to a reviewed publication when those are ready.
