资源简介：
The Massachusetts Department of Transportation Highway Division Vehicle Miles Traveled Road Inventory contains the spatial linework for all the public and a good portion of the private roadways in Massachusetts, along with roadway attributes covering the roadway classification, ownership, physical conditions, traffic volumes, pavement conditions, highway performance monitoring information, and more. This version has been processed to both include VMT and to eliminate overlaps among features in the Road Inventory Linear Referencing System.
