Speed limit: 1 minute per hour

Where can I find a map that shows driving distance instead of just physical distance?

It would probably be too hard to redraw a map where 1 inch = 1 minute, due to the havoc caused by freeways and slower roads.

But I'm hoping to find something like Google maps where you put an address and it draws concentric circles of driving time around that address, or better yet, colors the entire map along a spectrum based on driving time, e.g. blue is really close and it shifts to green, orange and then red, being the farthest.

Or maybe there's a painless way to calculate this for myself?

Something like Mapificient?

Or like this?

Upon further examination, Mapificiant I think is focused on public transit, not driving time.

Google Maps does this.

Punch in an address and hit Enter. On the left side, under the address you punched in, click Directions. Punch in the other address and hit Enter. The drive time is listed right there.

@Sys Rq: I'm not looking for how to find the driving time between point A and point B. I'm trying to find the driving time between point A and every other point on the map.

(And, uh, the driving distance, too.)

Oh. I see. Never mind.

@Admiral Haddock: wow that's exactly what I'm looking for, if only it weren't public transportation! I want something just like that for cars!

er... I meant @RobotHero.

brenton, it looks like you can select slow cars and fast cars as an option on that link.

@Admiral & Reductiondesign: very neat and useful tool. This is pretty close to what I want, though it's too bad that it assumes that you just have a flat-rate of speed, and doesn't calculate varying road speeds and stoplights like Google maps does.

I think my link does do that for cars (albeit in metric, so you have to convert it to miles).

Should have previewed. You're right, it is a bit blunt a tool in that regard.

You could search for "isochrone map." (Too busy to do this now, apologies.)

If you want to help build it, I'm working on a general purpose trip planner which will eventually support isochrone mapping (there was a post on our developers mailing list about it in the past couple of days). The project is OpenTripPlanner. It presently only barely supports cars (no speed limits; no left turn a bit broken in the presence of transit), but that would be relatively easy to change (especially if you don't care about drive-to-transit).

Just after I posted this, my colleague called me over to show me a demo of the isochrone code; I begged him to send me a screenshot and he did. It's just a demo, and of course shows transit rather than driving times, but it's a start.

@novalis looks awesome, be sure to post a link to it here when you finish the project. If you do get it to work with cars and to take into consideration all the driving considerations then it will be just amazing. I see that it works with a slider right now, which is great. If you want to really make it awesome, you'll consider developing an option that will automatically calculate out a bunch of different "max times" on your scale within a range and overlay them, displayed in a gradient of colors. For example: 0mins , 5mins, 10mins, 15mins, 20mins. (increment: 5, range: 0-20.) Do you need a HTML/CSS/Javascript guru on the project?

What you're describing reminds me of a feature in Padmapper. I think this might be what you're looking for?

Unlike other sites I've found, it seems to take actual driving conditions into account (i.e., you can travel a greater distance in 10 minutes on a freeway than in 10 minutes on a neighborhood street).

In a previous thread, mefi's awesome GIS guru desjardins currently on a road trip posted this driving time mapper based on GMaps.
