If you want to know what traffic is like, you should be able to tap into the sensors of people’s phone while they are driving. The concept is also called a micro-blog, which is a similar concept to Wikipedia, where people upload their own content from their phones.

Currently, there’s a working prototype for the Nokia N95 mobile phone, but the application will be ported to other phones.
