I had actually almost exactly the same problem that is why I created: http://crib.ninja It allows to save apartments across different websites and automatically extracts the information (like rent, size, bedrooms, bathrooms, location, ...). The apartments can then also be displayed on a map with a kind of travel-time heatmap from https://www.route360.net . Additionally is it possible to sort or filter by any of the p…

Would be nice to put that on the front page: Currently we concentrate on the US and Germany.

In this type of the task only payoff makes sense. With 30B+ paths and additional f(x) of path and sum of paths, real life optimization is not really possible - I'll bet in the middle of the night that some simple heuristics (e.g. proximity to one of the major transport hubs) will perform much much better. And city prices are likely already reflecting this, contrary to what author claims.

That's considering commute time is somehow directly related to price, which isn't true.

Your commute depends on your job, where the price depends on safety, size, shops in the area, noise pollution, air pollution, parc proximity etc...

Connection is one factor but you can't just say "it's expensive, therefore faster to go to work"

Just because that is what it currently concentrates on does not mean that it should not work perfectly fine for other countries ;-)

If somebody adds a page that does not work they can simply click on the (!) and inform us, we add then support asap.

Genius. My only comment is in how you measure the value of an address. It seems very likely that your algorithm would converge to areas that are only centrally located.

Perhaps it could be improved if the algorithm took an input of common routes and times, then tried to find an optimal location for these routes. This way the algorithm could be scaled as needed and provide a more realistic scenario. Is this something you considered?

This reminds me of the "Space Syntax" school of urban planning and architecture (which basically adopts a computational/graph-theoretic/topological approach by computing the simplicity of paths between various points and all other points).

Nice work, is the source available? I'd love to do something similar for Sydney, Australia.

Unfortunately not. I created it with various programs I've written for my data visualisation videos ( https://www.youtube.com/user/laurivanhala )

Your maps are gorgeous. Would you mind to share which tileset are you using in the Helsinki map?
