Located at the crossroads of America, Indiana is a vital component of our national transportation network. Approximately 82 million people live within 500 miles of Indianapolis, and 65% of the U.S. population is within a day’s drive. The Indiana interstate system includes more than 1,100 centerline miles. This mileage is roughly 10% of the Indiana Department of Transportation (INDOT) roadway system, but it carries over 35% of the vehicle miles traveled (approximately 16 billion vehicle-miles in 2011).
This collection was established as a repository for an annual mobility report jointly produced by INDOT and Purdue University. The tools and data described in this annual report provide a quantitative evaluation of how the Indiana interstate system is performing, where opportunities lie for future infrastructure investments, and the reduction in congestion when new infrastructure investments are completed. In subsequent years, this collection will be expanded to include additional Indiana roads.
