Road Signs In The United States
In the United States, road signs are, for the most part, standardized by federal regulations, most notably in the ''Manual on Uniform Traffic Control Devices'' (MUTCD) and its companion volume the ''Standard Highway Signs'' (SHS). There are no plans for adopting the Vienna Convention on Road Signs and Signals standards. The 1971 MUTCD adopted several Vienna Convention-inspired symbol signs with the intent to transition to symbols in lieu of words as "rapidly as possible", but U.S. drivers were baffled by symbol signs. Available through ProQuest Historical Newspapers. The language about "rapidly" transitioning to symbols quietly disappeared in the 1978 MUTCD. The result was to effectively freeze several measures intended to be temporary until U.S. drivers could learn the relevant symbols' meanings. For example, the "Do Not Enter" word message is not found on the Vienna Convention's equivalent sign. Two symbol signs were eliminated, respectively, in the 2000 and 2003 MUTCDs (there ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Logo Sign
Logo signs (also known as specific service signs or Logo service signs, or colloquially as Big Blue Signs) are blue road signs used on freeways that display the logos or trademarks of businesses before travelers reach an exit or interchange. Typically, a business pays a small fee to a transportation department (or to a subcontractor of a transportation department such as Lamar Advertising subsidiary Interstate Logos) to have their logos displayed on a large panel alongside other businesses. Depending on the jurisdiction, businesses may have to meet certain criteria such as hours of service and distance from the sign. History Logo signs were permitted on rural Interstates beginning in 1965 as part of the Highway Beautification Act, though the signs did not come into general use, especially in the western states, until the mid 1970s. Originally, such signs were limited to gas, food, lodging, etc.. In the United States The 1976 amendments to the Highway Beautification Act exp ...

Control Cities
A control city is a city, locality, or other location posted on a series of traffic signs along a particular stretch of road indicating destinations on that route. Together with route numbers and cardinal directions, these focal points aid the motorist navigating along a highway system. Such cities appear on signs at junctions to indicate where the intersecting road goes and where the road ahead goes. They are also typically used on distance signs. Different countries have different practices as far as focal points on directional signs are concerned, and the term control city is not used globally. Where a sign contains a number of destinations for a particular direction, not all of those destinations may be considered a control city. In most countries, control cities are perceived to be the destinations on signs that aid longer-distance traffic, as opposed to local traffic. Accordingly, local destinations on a sign, which only appear incidentally, would in a number of countries n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reassurance Marker
A reassurance marker or confirming marker is a type of traffic sign that confirms the identity of the route being traveled on. It does not provide information found on other types of road signs, such as distances traveled, distances to other locations or upcoming intersections, as is done by highway location markers. It is a highway shield, usually with a cardinal direction sign, that repeats the name or number of the current route. They are typically posted at intervals alongside a numbered highway. North America In the United States and Canada, reassurance markers (also called reassurance shields or confirming shields) usually take the form of a shield displaying the road number on an elevated pole, with a plate above or below it indicating the "official" direction of that side of the route. (The official long-range direction may differ from the short-range direction; for example, a large stretch of I-90 near Buffalo, New York runs north–south, although the route is offi ...

Limited-access Road
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, limited access freeway, and partial controlled access highway, 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 Dual carriageway, separation of opposing traffic flow, use of grade separated Interchange (road), interchanges to some extent, prohibition of slow modes of transport, such as bicycles, Working animal, (draught) horses, or self-propelled agricultural machines; and very few or no intersection (road), 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.''Manual on Uniform Traffic Control Devices''Section 1A.13 Definitions of ...

Freeway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include '' throughway'' and '' parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arter ...

Speed Bump
Speed bumps (also called traffic thresholds, speed breakers or sleeping policemen) are the common name for a class of traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions. Variations include the speed hump, speed cushion, and speed table. The use of vertical deflection devices is widespread around the world, and they are most commonly used to enforce a low speed limit, under or lower. Although speed bumps are effective in keeping vehicle speeds down, their use is sometimes controversial—as they can increase traffic noise, may damage vehicles if traversed at too great a speed, and slow emergency vehicles. Poorly-designed speed bumps that stand too tall or with too-sharp an angle can be disruptive for drivers, and may be difficult to navigate for vehicles with low ground clearance, even at very low speeds. Many sports cars have this problem with such speed bumps. Speed bumps can also pose serious hazards to mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runaway Truck Ramp
A runaway truck ramp, runaway truck lane, escape lane, emergency escape ramp, or truck arrester bed is a traffic device that enables vehicles which are having braking problems to safely stop. It is typically a long, sand- or gravel-filled lane connected to a steep downhill grade section of a main road, and is designed to accommodate large trucks or buses. It allows a moving vehicle's kinetic energy to be dissipated gradually in a controlled and relatively harmless way, helping the operator stop it safely. Design Emergency escape ramps are usually located in mountainous areas which cause high construction costs and present difficult site selection. A ramp may cost US$1 million. Designs include: *''Arrester bed'': a gravel-filled ramp adjacent to the road that uses rolling resistance to stop the vehicle. The required length of the bed depends on the mass and speed of the vehicle, the grade of the arrester bed, and the rolling resistance provided by the gravel. *''Gravity escape ra ...

National Network
The National Network (or National Truck Network) is a network of approved state highways and interstates for commercial truck drivers in the United States. The Surface Transportation Assistance Act of 1982 authorized the establishment of a national network of highways designated for use by large trucks. On these highways, Federal width and length limits apply. The National Network (NN) includes almost all of the Interstate Highway System and other, specified non-Interstate highways. The network comprises more than of highways. Definition §658.9 National Network Criteria The National Network listed in the appendix to this part is available for use by commercial motor vehicles of the dimensions and configurations described in §658.13 and §658.15. For those States with detailed lists of individual routes in the appendix, the routes have been designated on the basis of their general adherence to the following criteria. * The route is a geometrically typical component of the F ...

Bypass (road)
A bypass is a road or highway that avoids or "bypasses" a built-up area, town, or village, to let through traffic flow without interference from local traffic, to reduce congestion in the built-up area, and to improve road safety. A bypass specifically designated for trucks may be called a truck route. If there are no strong land use controls, buildings are often built in town along a bypass, converting it into an ordinary town road, and the bypass may eventually become as congested as the local streets it was intended to avoid. Petrol station A filling station, also known as a gas station () or petrol station (), is a facility that sells fuel and engine lubricants for motor vehicles. The most common fuels sold in the 2010s were gasoline (or petrol) and diesel fuel. Gaso ...s, shopping centres and some other businesses are often built there for ease of access, while homes are often avoided for noise and pollution reasons. Bypass routes are often controversial, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weigh Station
A weigh station is a checkpoint along a highway to inspect vehicular weights and safety compliance criteria. Usually, trucks and commercial vehicles are subject to the inspection. Weigh stations are equipped with truck scales, some of which are weigh in motion and permit the trucks to continue moving while being weighed, while older scales require the trucks to stop. There are many different scales used, from single axle scales to multi-axle sets. Signal lights indicate if the driver should pull over for additional inspection or if they are allowed to return to the highway. Many jurisdictions employ the use of portable scales, allowing weigh stations to be set up at any point. Portable scales allow states to set up temporary scales for situations such as seasonal check points, temporary checkpoints on isolated roads often used by trucks, or to prevent drivers from avoiding scales at fixed locations. Portable scales may be set up at purpose built locations that are not normally st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
