You weren’t doing anything productive today, were you? Because this neat online game has the potential to waste hours – or even days – of your life as you attempt to build the perfect subway system. Tweak the existing system to make it just so, or start from scratch and build your own dream network. The game will rate you on estimated ridership and per-ride cost, as compared against the baseline of the current system. 

There’s some serious numbers under the hood of this game – census and employment data, existing transportation demand and so on – but Jason points out that the simulation is meant to be a bit of fun and not taken too seriously as a planning tool. But what are you waiting for? Go and get started by clicking here! I’m certainly going to take it for a serious spin when I have some spare time.

(Also, read Jason’s summary of the project – lots of great background info!)
