The Road Inventory is a GIS-based asset management system for the state's highway transportation system. As such, its strengths are in describing the configuration and condition of public roads and rights-of-way. It is not designed to support route-finding (e.g., shortest path applications), nor is it designed to support geocoding (although in theory intersection-based geocoding could be set up on it). It is part of the official documentation of the state road system and is used to prepare the yearly Highway Performance Monitoring System (HPMS) report to the Federal Highway Administration (FHWA). It is a record of centerline and lane miles, which are the basis of state reimbursements to localities for road maintenance expenses (Chapter 90 funds).The Massachusetts Department of Transportation Highway Division 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 eliminate overlaps among features in the original distributed by MassDOT and to add pavement data, which is no longer attached by MassDOT.

Abstract: The Massachusetts Department of Transportation Highway Division Traffic 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, traffic volumes, and more.

Formerly known as the Massachusetts Highway Department (MHD) Roads, then the Executive Office of Transportation - Office of Transportation Planning (EOT-OTP) Roads, the MassGIS-MassDOT Roads layer includes linework from the 1:5,000 road and rail centerlines data that were interpreted as part of the 1990's Aerial Imagery project. The Massachusetts Department of Transportation - Office of Transportation Planning, which maintains the primary source for this layer, continues to add linework from municipal and other sources and update existing linework using the most recent aerial ortho imagery as a base. The attribute table includes many "road inventory" fields maintained in MassDOT's linear referencing system.The current MassGIS-MassDOT hybrid data layer was first published in November 2018, based on the MassDOT 2017 year-end Road Inventory layer and results of a 2014-2015 MassDOT-Central Transportation Planning Staff project to conflate street names and other attributes from MassGIS' "base streets" to the MassDOT Road Inventory linework. The base streets are continually maintained by MassGIS as part of the NextGen 911 and Master Address Database (MAD) projects. MassGIS staff reviewed the conflated layer and added many base street arcs digitized after the completion of the conflation work. MassGIS added several fields to support legacy symbology and labeling. Other edits included modifying some linework in areas of recent construction and roadway reconfiguration to align to 2017-2018 Google ortho imagery, and making minor fixes to attributes and linework. MassGIS continues to modify the layer as needed, modifying the linework using the latest aerial imagery and adding line features from the base street arcs.From this data layer MassGIS extracted Major Roads and Major Highway Routes layers.See full metadata

The Massachusetts Department of Transportation Highway Division 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 by CTPS to eliminate overlaps among features in the original distributed by MassDOT and to add pavement data, which is no longer attached by MassDOT.

Functional Classification refers to the character of services that a particular roadway is intended to provide. In general, roads either serve to provide mobility for vehicles or access to locations. The process of functional classification was mandated by Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and implemented in 1993 by the Office of Transportation Planning in cooperation with the 13 Regional Planning Agencies. Roadways are divided into the following three classification categories:Arterials: These roadways provide the highest level of mobility at the greatest vehicular speed for the longest uninterrupted distances and are not intended to provide access to specific locations. Arterials are further subdivided into Principal Arterials and Minor Arterials. However, for the purposes of this report they have been grouped together. Please note that Interstates are considered Arterials, but they have been given their own category in this report.Collectors: These roadways provide some level of both mobility and access. They collect traffic from Local roads and funnel it to Arterials. In rural areas, collectors are further subdivided into Major Collectors and Minor Collectors, but for the purposes of this report they have been grouped together.Locals: These roadways provide access to abutting land with little or no emphasis on mobility. The termLocal road should not be confused with local jurisdiction. Most, but not all, functionally classified Local roads are under city/town jurisdiction.

This polygon data layer contains the six Massachusetts Department of Transportation (MassDOT) Highway Districts in the Commonwealth of Massachusetts. The districts supervise all construction within its jurisdiction; performs on-site engineering; implements maintenance and preventative maintenance programs; generates proposals for maintenance and construction work; and provides engineering support to cities and towns.ProductionThe bounds of the MassDOT Highway Districts were digitized from the MassGIS survey-level town boundaries. In addition to the polygon layer, there is an arc layer following the sameline workas the polygon included in thedownloadableshape file.MetadataStatusThis data is current as of September 2013.

File geodatabase layer containing a year-end snapshot of the spatial line work for all the public and a good portion of the private roadways in Massachusetts. This includes the roadway attributes covering the roadway classification, ownership, physical conditions, traffic volumes, pavement conditions, highway performance monitoring information, and more.

This layer displays all projects that can be spatially represented from Project Info.

These layers display the approximate location of the plan sheets of state highway layout plans and state highway alteration plans. This layer is not intended to be used in any way to precisely locate the baseline or the sidelines of highway layouts. The highways shown on this layer are the state highways under the jurisdiction of the Massachusetts Department of Transportation Highway Division. Some MassDOT projects included work outside state highway limits. As a result, other highway/roadway layouts shared on this layer represent portions of other state agency/department/authority roadways, portions of county highways, or portions of municipal roadways.

GIS Maps, Transportation Data, and Reports for all modes of travel throughout Massachusetts.

Aid Category refers to funding categories that have been established by ISTEA and TEA-21. The RoadInventory directly identifies which roadways fall under the National Highway System Federal Fundingcategory and indirectly identifies which roadways fall under the Surface Transportation Program Federalcategory and Non-Federal Aid category. These three funding categories are described below:National Highway System (NHS) funded roadway network represents all Interstate roadways and principalarterials spanning the state in accordance with the Moving Ahead for Progress in the 21st Century Act(MAP-21). In addition, roadways connecting the NHS roadways with military bases (known as theStrategic Highway Network) are also considered part of the NHS network. NHS passenger and freightterminals are connected by roadways called NHS connectors.Surface Transportation Program (STP) funded roadway network is comprised of any functionally classifiedroadway. STP funded roadways include all urban arterials, urban collectors, and rural arterials. Accordingto the TEA-21 legislation, rural collectors are STP-eligible, but have a limitation on the STP fundingamount.State and Local Aid includes chapter 90 and other non-Federal Aid categories. Roadways that fall underthis category are comprised of roads functionally classified as local roads.Fd_Aid_Rd: Federal Aid Eligible Roads (National Highway System and Surface Transportation Program)0 = Not Eligible1 = Interstate - NHS2 = Other Road - NHS3 = STP Eligible4 = STP Road - C15

This point data layer contains the traffic count locations obtained by the MassDOT Highway Division. The count locations represent a sampling of the roadway system. The interstate system is sampled at 100%, while the other functionally classified roadways are sampled at locations across the state.

A point feature for end treatments on Massachusetts Department of Transportation roadway. Contains fields such as Type, Manufacturer, Damaged. This data was collected by Patrick Engineering, owned by MassDOT.

The Interchange Segments layer contains linework designating the precise beginning and end points of every highway interchange in the State of Massachusetts. Different from intersections, the interchanges layer represents the convergence points between roads, one of which must be of state highway functional class or higher, and requires the use of on and/or off ramps to facilitate travel between them.

The pedestrian dataset is a layer that aims to delineate the position and quality of pedestrian facilities throughout the commonwealth of Massachusetts. Using aerial photography, pedestrian facilities were created to display the presence of right, left or both sides of the road. Sidewalk widths are included.

The Massachusetts Department of Conservation and Recreation (DCR) – Division of State Parks and Recreation (DSPR) Roads and Trails datalayer contains all legal roads and trails (lines and point features) identified by DCR staff and consultants on DCR DSPR properties (as well as some of the Urban Parks; eventually all trails on these properties will be integrated into this dataset).Roads and trails on private and non-DCR public land were mapped if they connected to these roads and trails and should be used with permission and should not be used if posted.More info...Feature service also available.

Updated version of MassDOT's Potential for Everyday Biking data layer. The Potential for Everyday Biking and Walking layers display latent demand for active-mode trip making and are implemented in various project prioritization processes. Methodology documentation available here.

HOW TO USE:

The legend breaks road segments into three categories: high, medium, and low. High indicates the road segment is in the top 10% of potential, medium indicates the top 60%, with low rounding out the remainder.

Note: a road segment's appearance in the map represents demand and may already have existing walking or biking infrastructure.
