Description: RETROART represents road centerlines along arterials designated "Retrograde Arterials" as part of the MEDOT's statewide Access Management program. A retrograde arterial is a mobility arterial where the access-related crash-per-mile rate exceeds the 1999 statewide average for arterials of the same posted speed limit. The MEDOT Access Management program envisions prioritized planning and preservation of Mobility Arterial corridors most at risk of losing capacity, safety, and of decreasing posted speeds, due to increasing development and commuter and visitor pressures. More about the Access Management Program can be found at http://www1.maine.gov/mdot/planning-process-programs/access-mngmnt.php . This dataset was created by Maine Department of Transportation using basemap line work (see the MEDOTPUB (ROADS) metadata for more detail). This dataset is designed for use in applications within MEDOT.
