Abstract. In this article, I describe mqtime, a new Stata library that provides
functionality to perform a variety of mapping tasks, including
calculating travel time, distance (driving, biking, or walking), and
estimated fuel use. mqtime uses an overlooked free and
open-source mapping service provided by MapQuest. This service has
significantly more attractive terms of use than widely used alternatives
(for example, Google Maps), which limit use to a few thousand queries per day.
Hence, mqtime makes analysis with even very large datasets
practical. I also provide a convenient function for geocoding character
addresses to geographic coordinates.
