Demonstration of the approach for other cities

[Robinlovelace]

Reproducible example shown below for Cardiff. Any other examples from other cities welcome. Should we add this to a new vignette? Thoughts welcome @layik, @ccamara or anyone.

Yes! I think this would be great to add in, both in terms of providing insight for our friends in Wales and as future prep for the 2021 census.

[Robinlovelace]

Great, could be a new vignetted. Input very welcome @natesheehan, thanks for the comment!

[natesheehan]

Welcome! Yes, I can write a vignette based on the example above ~ this week?

[Robinlovelace]

That would be amazing!

[cristitosa]

Has there been any documented case studies for cities outside the UK, and the customization of the PCT tool? Thank you.

[Robinlovelace]

Hi @cristitosa yes, work building on the PCT have been developed in Norway and New Zealand, in prototype mode. We are actively working on developing a strategic cycling uptake model for the Republic of Ireland and Lisbon region, Portugal. Are you interested in deploying the methods in Romania (based on your GitHub bio)? Happy to help!

[cristitosa]

Hi @Robinlovelace thank you for your reply. Good to know! At the moment I am not in Romania, but surely it is needed there as well. Currently a postdoc in Stavanger, Norway, and a PhD student @ayda89 of ours wanted to explore the PCT.

[Robinlovelace]

OK great, I can link up with you on that. Please drop me an email at r. lovelace at leeds dot ac dot UK (sorry for cryptic email address)!
