Interactive Map - 2045 Population & Employment Data

Tri-County staff has completed analysis and disaggregation of future 2045 population, household, and employment data throughout the 1,139 Traffic Analysis Zones (TAZ) within the region. This future socioeconomic (SE) dataset is a byproduct of the report, "The Economic and Demographic Outlook for Michigan Through 2045," prepared for the Michigan Department of Transportation, generally every four years, by the University of Michigan's Institute for Research on Labor, Employment and the Economy.

Traffic Count Database System

TCRPC's innovative Traffic Count Database System (TCDS) is a regional depository and an interactive map tool for current and historical traffic count data. Under "TOOLS" are GIS layers depicting TIP Projects (2009-2013) as well as 2035 modeled traffic trend deficiencies for AM and PM rush hours. For more information or navigational assistance, please contact Transportation Planner Paul Dionne.

Michigan Traffic Crash Facts

The Michigan Traffic Crash Facts (MTCF) website provides users with annual official Michigan crash data. There are two sections to the website: the Publications section that contains crash data statistics dating back to 1952; and the Data Query Tool, which allows users to perform advanced searches.

Wellhead Protection Viewer

The Wellhead Protection Viewer is a map-centric GIS database. The Viewer includes the Potential Contaminant Source Inventory, Water Wells, Time of Travel areas, and other layers that are used by planners when making development decisions that may affect regional groundwater resources.

2015 Aerial Flyover Photography

In 2015, TCRPC served as a facilitator between our regional partners and the state during this multi-month pro-ject. The Flyover was part of a state-wide effort managed by the Michigan Dept. of Budget and Management, funded by local and county agencies and public utilities. In mid-April 2015, aerial data was collected in Eaton, Clinton and Ingham Counties by airplane. Early spring "leaf-off" conditions allowed for a greater level of the ground level detail without the interference of leaves on trees. The aerial flyover provides mid-Michigan with 3" resolution photographs of our landscape in our urbanized areas and 6-inch resolution in suburban and rural areas. If you have questions, please contact Senior Transportation Planner Laura Tschirhart at or call (517) 393-0342 x21. If you are interested in obtaining images from the regional flyovers, please contact the appropriate municipality.
