Using Twitter to improve public transports

I’m Impressed by this new project by Eric Fischer. ‘He used Geotagged Tweets to create maps of the most highly trafficked thoroughfares in major cities’ such as New York, Chicago, and San Francisco Bay Area.

Here’s an example of the traffic flow in Chicago. As you can see there’s a highlighted curve heading Southwest area, but there’s no transit line so this information could be useful to create one.

In this example from NY Map we can see how neighborhoods are created around subway lines.
I personally like this kind of projects that use Social Media API’s in order to create something artistic and useful. That’s the success key for me.
