😊 One of my main PhD papers is out: 'Incorporating diminishing returns to opportunities in access: Development of an open-source walkability index based on multi-activity accessibility'.

What it's about 🧵
As part of a property price modelling project, I wanted to build an 'open Walkscore' using Pandana, as suggested in their original paper (https://onlinepubs.trb.org/onlinepubs/conferences/2012/4thITM/Papers-A/0117-000062.pdf).
This led to thinking about:
• what could be in a walkability index, answer: everything - which also means you can use the same design for other modes,
• how to incorporate people's desire to visit multiple places: incorporates infinite destinations, but with diminishing returns to increasing destination numbers, and

May still publish the hedonic side of it in the future (it became much too big to fit in this paper) but concentrating on writing that up as a chapter to get my thesis out the door right now.
