Studies

Studies help MDOT determine project need, as well as environmental, cultural, and social impacts. Studying a proposed project/area and giving the public an opportunity to participate in the transportation decision-making process ensures a better outcome for all Michigan residents.

Planning and Environmental Linkages (PEL) process approach to transportation decision-making considers environmental, historical, cultural, and feasibility issues early in the transportation planning process. Public engagement gives the community the opportunity to be part of the process and guide the project team to acceptable decisions. The information analysis and products developed during the PEL study is then used to inform the formal federal National Environmental Policy Act (NEPA) environmental review process.


 

Traffic & Environmental Assessment, often called an EA, is required when the significance of the environmental impacts are uncertain. The purpose of this process is to clarify any uncertainty and document the finding. If no significant impacts are found, the process is concluded with a finding of no significant impact, referred to as a FONSI. But if there are significant impacts, an environmental impact statement, or EIS, is then completed.


 

These guidelines ensure the public has ample opportunity to effectively participate in transportation decision-making. They also ensure that the development of transportation programs and projects in Michigan support federal, state and local goals and objectives.
