Do you consider yourself a transit nerd? The Center for Neighbourhood Technology has a doozy of a challenge for you: An quiz that asks you to name a US city based on a map of its public transportation system. The rub: It only shows you the stops. You can't see the routes.
The online quiz is simple. Each stop is represented by a dot, which is assigned a colour based on how often the stop is in use. Darker dots are higher frequency. You can also choose higher levels of difficulty — which, intriguingly, will introduce you smaller cities that you might not even know had such extensive transit systems.
Luckily, each quiz presents you with four potential cities to choose from, so you're able to make a somewhat educated guess if you know a little about the urban design of the city itself. But some of these are still really hard! How'd you do? [CNT via Citylab]
