Project Description: Anadded travel lanes project along a portion of the SR 23 corridor in St. Joseph County was planned by INDOT. In order to assist with the design of this project, traffic projections were requested at 15 intersections for the years 2015, 2012, 2030, and 2032. At these intersections, all inbound legs, including turning movements and outbound legs were considered. The growth rates generated were used to project traffic data from 2008 to 2010, 2012, 2030, and 2032. The traffic data was expressed in terms of average annual daily traffic (AADT), AM and PM design hour volumes (DHV), DHV as a percent of AADT, and the percentage of commercial vehicles for both AADT and DHV.
