Re: Maps that show time instead of space

I had this though many years ago, but unlike distance, travel time isn't necessarily symmetric, and so it isn't possible to represent time just by warping a conventional map as A->B and B->A will get the same warp.

And if the map allows for different travel modes, like train vs driving, I think it breaks entirely.

But this isn't to poop on the website -- I'm glad someone has taken the time to build a demo, even it it can't handle some cases.

Does this not work on mobile? If it does, can someone explain how to use it? No matter what I do, the map just warps a bit, and nothing else happens.

IMO, I expected that I could click various places and the map would react to the specific point I clicked.

Instead, it seems to essentially just be an animation between two pre-determined images.

After some experimentation- opening the hamburger menu and turning on "focus on hover" behaves this way.

And then panning kind of works? I feel like there's either a bug or it isn't meant for mobile

This sounds conceptually difficult: Wouldn't the presence of one-way streets or airport security checkpoints, for example, mean that the travel time from A to B might not be the same as the travel time from B to A? How can a map then be drawn?

Right. There could be northbound traffic but not southbound for example. The answer is they must be symmetrizing the distances somehow. Alternatively, you could show the travel times _from a source location_ unambiguously, which might be more interesting for the average user (e.g. from home)

Yeah, this is what I was hoping for with the touch. Seems like where I touch should be the origin and distance in x/y should represent time to travel from that origin.
