This data is recorded as part of the State of Michigan's Transportation Asset Management Council annual road condition assessment. Pavement condition data is collected by crews that include people from SEMCOG, road commissions, the City of Detroit, and MDOT. The pavement condition rating on local roads is collected by the community that has jurisdiction over the road.
The source of this data is from Southeast Michigan Council of Governments' (SEMCOG) open data portal. The data has been filtered to only include streets within the City of Detroit, and modeled to align with our data standards.
