Central Indiana Suburban Transportation and Mobility Study

CISTMS (pronounced as "systems") is a regional transportation planning study that is being conducted by INDOT in the nine-county Central Indiana area.*

The main purpose of the study is to identify key issues and problems pertaining to suburb-to-suburb mobility in the nine-county Central Indiana region and to determine how those can best be addressed from a transportation planning perspective. The study area includes Marion County but is focused on the 8 surrounding counties: Boone, Hamilton, Madison, Hancock, Shelby, Johnson, Morgan and Hendricks.

The following state route corridors are being examined in CISTMS: SR 32/38 on the north, SR 9 on the east, SR 44/144 on the south and SR 267/39 on the west. Parallel routes (such as 146th Street in Hamilton County, the proposed North-South Corridor (Ronald Reagan Parkway) in Hendricks County and the proposed East-West Corridor in Johnson County) will also be examined as appropriate. The study will evaluate a broad range of options for meeting existing and future transportation needs in the study area.
