About IMPO

Planning Area: The MPO is responsible for transportation planning in the area defined by the most current Census as being urbanized, plus the area anticipated to be urbanized by the year 2035. This area is known as the Metropolitan Planning Area (MPA). The present MPA is based on the 2010 Census and includes all of Marion County and portions of the surrounding counties of Boone, Hamilton, Hancock, Hendricks, Johnson, Morgan, and Shelby where suburban growth has occurred. The current MPA includes the following cities and towns:













Core Activities: The core activities of the MPO involve the Indianapolis Regional Transportation Plan, the Indianapolis Regional Transportation Improvement Program (IRTIP), Air Quality Conformity Analysis (for both the Plan and the IRTIP), and the Public Involvement Plan. In addition, the MPO annually prepares a Unified Planning Work Program of transportation-related planning studies/activities to which it recommends committing currently available funds over the next twelve months.


Community Involvement: teMPO is the email-newsletter of the regional transportation planning process, which is distributed to more than 2,300 individuals and organizations, including elected officials, neighborhood and civic associations, special interest groups, news media, libraries and government agencies. The newsletter is issued several times a month.  To stay up-to-date with what's happening in Indianapolis' regional transportation planning, subscribe to receive the latest edition of teMPO by clicking on the Subscription Page. To view past issues of teMPO, click on teMPO-Newsletters.


Decision-Making: MPO plans and recommendations are developed in cooperation with the Indianapolis Regional Transportation Council (IRTC). MPO plans and recommendations are presented to the IRTC for approval and/or adoption. The IRTC is a voluntary, inter-governmental body, created to promote cooperation and coordination among the area’s local governments. The IRTC is composed of a Policy Committee and an Inter-agency Technical Committee. The IRTC Policy Committee consists of the heads of local governments and public agencies within the Indianapolis Metropolitan Planning Area. The IRTC Inter-agency Technical Committee consists of planners and engineers from the local governments and public agencies within the MPA. The IRTC meets quarterly. MPO plans and recommendations are endorsed by IRTC’s Inter-agency Technical Committee before going to its Policy Committee. The Policy Committee approves and/or adopts plans and recommendations, typically by resolution.
