2011 Indiana Interstate Mobility Report: Summary Version

Published as part of the Joint Transportation Research Program (JTRP) by Purdue University Press and Indiana Department of Transportation, the 2011 Mobility Report?Summary Version introduces the use of crowd sourced probe data collected from vehicles and mobile devices to quantify the location and duration of congestion on Indiana interstates.  The report presents a detailed case study of the I-65 corridor, as well as examples of travel time reliability information for sections of Interstates 65, 70, and 94.  Summary monthly mobility statistics for all 943 centerline miles of Indiana Interstates 64, 65, 69, 70, 74, 94, and 465 are tabulated in a graphical format to facilitate comparison of mobility along those corridors. 

Just over 75 years ago, on March 2, 1937, the Indiana General Assembly passed a resolution that the motto for Indiana would be ?The Crossroads of America.? Nine days later, on March 11, 1937, the Indiana General Assembly passed enabling legislation that led to the formation of the Joint Highway Research Project (JHRP) to facilitate collaboration between Purdue University and what was then known as the Indiana State Highway Commission. The Joint Highway Research Program was renamed the Joint Transportation Research Program (JTRP) in 1997 to reflect the state and national efforts to integrate the management and operation of various transportation needs.

Over 1,500 technical reports are currently available, published as part of the JHRP and subsequently JTRP collaborative venture between Purdue University and what is now the Indiana Department of Transportation.  Free online access to all reports is provided through a unique collaboration between JTRP and Purdue Libraries.  These are available at docs.lib.purdue.edu/jtrp. Since 2006, there have been over 333,000 downloads of these reports worldwide.
