Morning everyone,

I'd like to share something I've been working on. It's called
Transitshed, and it's here:

http://ec2-75-101-230-178.compute-1.amazonaws.com/index

You enter a time and click on the map to see everywhere you can get,
using public transit, within a certain amount of time. This is a
temporary demo, and it's bound to either crash or be taken down as I
work on it.

Wow! I think that this is the first time-travel map that I've ever
seen that can recalculate for arbitrary points.

Is it the same cost to do an arrive-by query?

Nope, it's just a depart-at query. Arrive-by queries are broken in the
repo HEAD, at the moment.

Brilliant - once I realised that it doesn't work on IE6 and I switched to
using Firefox, where it does work!

Very cool, Brandon!

Another one saved ;-) Let's hope the switch is permanent!

Neato! Is it using alpha shapes or (judging by the name) watershed
algorithms?

It's using quikgrid to generate the contour polygons.

Ah, so you're gridding all the time values then generating a contour
at the range time. Very slick, and that explains the "islands" it
generates.

Brandon,

This is great, the possibilities in the real-world use are endless.

Good luck.
