Writing for the Urbanophile, Drew Austin argues that such information can change the way cities approach their transportation problems.
"The taxi perfectly illustrates the opportunities these incidental data sources create as well as the limitations of what they can tell us. Transportation is one of the trickiest and most critical problems in any city, and one of the areas where good data can help the most. By recording their own activity, taxis become sensors that roam the city painting a detailed picture of traffic conditions, travel demand, and even the locations where passengers give the best tips. We can learn a lot about the city from taxis, but we can learn even more about taxis themselves and their role in the urban environment."
