The stated purposes of the Master Plan include determining roadway classification and design standards, such as “the planned number of travel lanes, target speeds, divided/undivided designation, transit and high occupancy vehicle (HOV) accommodations, pedestrian and bicycle accommodations, and right-of-way widths,” (Maryland-National Capital Park and Planning Commission, 2018). The document indicates that the Master Plan “encapsulates all existing and planned transportation facilities, and preserves planned rights-of-way to accommodate future transportation systems, including highways, transitways and pedestrian and bicycle facilities.” It is a long range planning and guidance tool for transportation investments and not specifically binding from a regulatory perspective, unless otherwise regulated at the local government level. Road classifications are defined with accompanying photos and include Freeways, Controlled Major Highways, Parkways, Major Highways, Arterial Streets, Minor Arterial Streets, Primary Residential Streets, Business Streets, Industrial Streets, Country Roads, Country Arterials, and Rustic Roads and Exceptional Rustic Roads. For each road, Master Plan includes the following information: • Segment length (feet or miles)
• Master Plan Right-of-way width (feet) • Road Code road (area) type classification • Target speed (miles per hour)
