MUTCD D6-4
The ''Manual on Uniform Traffic Control Devices for Streets and Highways'' (usually referred to as the ''Manual on Uniform Traffic Control Devices'', abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and traffic light, signals are designed, installed, and used. Federal law requires compliance by all traffic control signs and surface markings on roads "open to public travel", including state, local, and privately owned roads (but not parking lots or gated communities). While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD. The MUTCD defines the content and placement of traffic signs, while design specifications are detailed in a companion volume, ''Standard Highway Signs and Markings''. This manual defines the specific dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Theodore Roosevelt Island
Theodore Roosevelt Island is an island and national memorial located in the Potomac River in Washington, D.C. During the Civil War, it was used as a training camp for the United States Colored Troops. The island was given to the federal government by the Theodore Roosevelt Association in memory of the 26th president, Theodore Roosevelt. Until then, the island had been known as My Lord's Island, Barbadoes Island, Mason's Island, Analostan Island, and Anacostine Island. The island is maintained by the National Park Service, as part of the nearby George Washington Memorial Parkway. The land is generally maintained as a natural park, with various trails and a memorial plaza featuring a statue of Roosevelt. No cars or bicycles are permitted on the island, which is reached by a footbridge from Arlington, Virginia, on the western bank of the Potomac. According to the National Park Service: "In the 1930s landscape architects transformed Mason’s Island from neglected, overgrown ...

Mount Vernon Trail
The Mount Vernon Trail (MVT) is an long shared use path that travels along the George Washington Memorial Parkway in Northern Virginia between Rosslyn and George Washington's home at Mount Vernon. The trail connects the easternmost portions of Arlington County, the City of Alexandria, and Fairfax County, and travels mostly on dedicated trail with a small portion on city streets. As part of U.S. Bike Route 1, the Potomac Heritage Trail and the East Coast Greenway, the MVT opened in April 1972 as a gravel path and was subsequently expanded and paved. The MVT is part of the much larger mid-Atlantic Potomac Heritage National Scenic Trail. History Separate bridle and footpaths were included in the 1890 and 1930 plans for the Mount Vernon Memorial Highway, as the George Washington Parkway was called before opening. Provisions for such paths were included in the construction of key bridges, such as the Boundary Channel Bridge on south Columbia Island and some short paths were ...

At-grade Intersection
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design. This article primarily reflects practice in jurisdictions where vehicles are driven on the right. If not otherwise specified, "right" and "left" can be reversed to reflect jurisdictions where vehicles are driven on the left. Types Road segments One way to classify intersections is by the number of road segments (arms) that are involved. * A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. * A four-way intersection, or crossroads, usually involves a crossing over of two streets or ...

Limited-access Highway
A limited-access road, known by various terms worldwide, including limited-access highway, partial controlled-access highway, and expressway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway (also known as a ''freeway'' or ''motorway''), including limited or no access to adjacent property; some degree of separation of opposing traffic flow (often being dual carriageways); use of grade separated interchanges to some extent; prohibition of slow modes of transport, such as bicycles, horse-drawn vehicles or ridden horses, or self-propelled agricultural machines; and very few or no intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.''

Washington, Alexandria And Mount Vernon Railway
The Northern Virginia trolleys were the network of Tram, electric streetcars that moved people around the Northern Virginia suburbs of Washington, D.C., from 1892 to 1941. At its peak, the network consisted of six lines that connected Rosslyn, Virginia, Rosslyn, Great Falls, Virginia, Great Falls, Bluemont, Arlington, Virginia, Bluemont, Mount Vernon, Fairfax, Virginia, Fairfax, Fort Belvoir, Camp Humphries, and Nauck, Virginia, Nauck, with two of the lines crossing the Potomac River into Washington, D.C. Two companies were founded in 1892: the Washington, Arlington and Falls Church Railway Company and the Washington, Arlington and Mount Vernon Railway. A number of communities developed along their routes. In 1910, they merged into the Washington-Virginia Railway. Its major lines converged at Arlington Junction, in the northwest corner of present-day Crystal City, Virginia, Crystal City south of the Pentagon, and in Rosslyn at the south end of the Aqueduct Bridge (Potomac Riv ...

Traffic Circle
A roundabout, a rotary and a traffic circle are types of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.''The New Shorter Oxford English Dictionary,'' Volume 2, Clarendon Press, Oxford (1993), page 2632 In the United States, engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate design rules to increase safety. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds through horizontal deflection and minimising T-bone and head-on collisions. Variations on the basic concept include integration with tram or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting the roundabout comes from one direction, instead of three, simplifying the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Scenic Byway
A National Scenic Byway is a road recognized by the United States Department of Transportation for one or more of six "intrinsic qualities": archeological, cultural, historic, natural, recreational, and scenic. The program was established by Congress in 1991 to preserve and protect the nation's scenic but often less-traveled roads and promote tourism and economic development. The National Scenic Byways Program (NSBP) is administered by the Federal Highway Administration (FHWA). Some scenic byways are designated All-American Roads, which must meet two out of the six intrinsic qualities. The designation means they have features that do not exist elsewhere in the United States and are unique and important enough to be tourist destinations unto themselves. As of January 21, 2021, there are 184 National Scenic Byways located in 48 states (all except Hawaii and Texas). History The NSBP was established under the Intermodal Surface Transportation Efficiency Act of 1991, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
