Transportation Planning

Tri-County Regional Planning Commission (TCRPC) was designated by the Governor as the Metropolitan Planning Organization (MPO) in 1973, responsible for fulfilling all federally required transportation planning requirements in the Lansing-East Lansing Metropolitan area throughout Clinton, Eaton and Ingham Counties (Michigan's tri-county region).

TCRPC ensures that existing and future expenditures for transportation planning projects and programs are based on a continuing, cooperative and comprehensive (3-C) planning process. Federal funding for transportation projects and programs in the tri-county area are channeled through the TCRPC. In accordance with federal regulations, TCRPC is required to carry out metropolitan transportation planning in cooperation with the state and operators of publicly owned transit services.


New Interactive Road Construction Map Tool

Tri-County Regional Planning Commission transportation staff has launched an online geographic information systems (GIS) application that provides up-to-date construction information for the region. The powerful, web-based map features all current 2017 regional road projects, in addition to past projects from 2016. It also gives the option to filter by projects within the City of Lansing. The public can use this tool to view the type of work being done, the street location, and start and end dates of road construction projects. Click here to explore the map.

Source inventory information was gathered extensively from the Michigan Department of Transportation, City of Lansing, City of East Lansing, Ingham County Road Department, Eaton County Road Commission, Clinton County, and Michigan State University. If you have any questions about this tool, its functionality, or the information provided by the map, please contact Transportation Planner Paul Dionne at 517-393-0342.

Non-Motorized Advisory Working Group

TCRPC is kicking off the regional Non-Motorized Transportation Plan (NMTP) update with a collaboration of key regional leaders—forming a Non-Motorized Advisory Working Group—tasked with the development and maintenance of a regional non-motorized plan. See what the development schedule and scope of work is for this group by clicking the links below.

Non-Motorized Transportation Plan Scope of Work Activities

Non-Motorized Plan DRAFT Goals and Objectives

This advisory working group, appointed by Capital Area Regional Transportation Study (CARTS) will be responsible for the development and maintenance of the Non-Motorized Transportation Plan (NMTP). This plan would identify the priorities of the region in terms of non-motorized travel. Drawing from localized efforts the regional NMTP, they will establish a regional priority network that could be implemented over time. Future non-motorized projects will be drawn from the regional NMTP. The NMTP will also serve as a long-range needs assessment for the non-motorized element in the long range plan. This group will be comprised of a wide variety of representatives from the non-motorized community as well as local engineers and planning staff. The time commitment for this effort is 4-6 meetings per year.

Transit Demand and Economic Prosperity Study

Selected Consultant Proposal

The purpose of this study is to determine latent transit demand and the economic impacts of additional transit services for the mid-Michigan area of Clinton Eaton, and Ingham counties. Funded by grants and local match, the study is underway. We anticipate preliminary results by the end of March, 2017. Please contact TCRPC Planners Rachel Elsinga ( or Jim Snell ( for information.


Interested in Traffic Counts?

The Tri-County Regional Planning Commission has an innovative Traffic Count Database System (TCDS) that acts as a regional depository as well as an interactive map tool for current and historical traffic count data collected from the following jurisdictions: Michigan Department of Transportation, Ingham, Clinton & Eaton County Road Commissions, City of Lansing, City of East Lansing, Michigan State University and Delta Township.

Pavement Surface Evaluation and Rating (PASER)

TCRPC is the responsible agency for coordinating with locals and the Transportation Asset Management Council to conduct PASER ratings for the tri-county area. For PASER ratings and more information visit the Michigan Transportation Asset Management Council. Image below from the TAMC shows the 2015-2014 pavement condition of federal-aid paved roads in theUniversity Region, which includes the Tri-County Region.

Michigan 2017 Roads and Bridges Annual Report

The Michigan Transportation Asset Management Council (TAMC) delivered the Michigan 2017 Roads and Bridges Annual Report to the Michigan Legislature and the State Transportation Commission. Michigan Law, MCL 247.659a(9), requires TAMC to file an annual report with the Legislature and State Transportation Commission by May 2 of each year. The report summarizes road and bridge conditions and provides condition projections into the future. The report also provides a synopsis of TAMC program activities and events over the past year.

News & Information from the Michigan Department of Transportation

There are many common myths and misconceptions about transportation in Michigan, from why MDOT replaces "perfectly good" signs to why current funding levels aren't enough to keep roads and bridges in good condition. Transportation Reality Check takes on some of these myths, and explains why MDOT does things the way they do.
