suggestion: Add a mode to compare cities directly at the same scale on the same page

[elypter]

I imagine a side by side view of 2 cities with a common scale and travel time. it would be interesting to see how far and where you can get in the same time in different cities. this can be an indicator for the quality of public transportation and it can give you a comparison between a city you know and a other cities. so you have a feeling about your average trips in your city and then you can see how far you can get in another city or how much effort it possibly is to get to the other end of the city in comparison to trips you normally do in your home city. you should be able to zoom in and out and change the travel time just like in the single city view but it should change the views of both cities identically.

Could you add a description for this, to flesh out what exactly you'd want this to look like? I've managed to parse it in my head a few different ways, and so I imagine it might be useful to flesh things out. Like, are we comparing Berlin and London? To what end? Compare the relative distances one can travel in a certain time? How do we choose starting points for each? (Because that can make a big difference.)

Or maybe you mean....... Anyway, could you flesh this out, in terms of what you're hoping for, and what motivates it?

[edit: I think this has been done to some extent since I wrote this comment.]

the starting point adds a whole other dimension. for comparison it would probably be best to chose the most used transport hub in each city as the starting point or let the user chose the startingpoint by himself.

Fair enough... but then what? What's the "user story" here? It seems you've added a description since my prior comment, and that definitely helps, but I'm still not sure how one might determine whether they've been successful in implementing this, because it's not quite clear to me how this differs from just loading up the other city and looking at it. I presume you're thinking of some UI linkage between the two displays? Is that just on time? Time and zoom level? Etc. And maybe what you've written now is enough for someone else to run with this... I'm just still unsure that I see what's driving this, what the fundamental motivations are, what the vision for it is, something.
