The Geospatial Resources Section of the Office of Transportation Planning prepares maps for the Executive Office of Transportation (EOT) and Massachusetts Highway Department (MassHighway), maintains the Massachusetts transportation geographic information system (GIS) layers, and provides the data used to prepare the Highway Performance Monitoring System, which must be submitted each year to the Federal Highway Administration.
Road Inventory
The Office of Transportation Planning creates and maintains the statewide road inventory database, used by EOT, MassHighway, other state agencies, Massachusetts Regional Planning Agencies, and Massachusetts cities and towns. This database is also used for reporting annual roadway statistics to the Federal Highway Administration for funding of non-central artery statewide projects and for determining the Chapter 90 money allocation based on road mileage. The Geospatial Resources Section maintains the accuracy of the road inventory database by continually updating the spatial linework representing the statewide roadway network and associated data.
