Overheight Vehicle Detection System
Bridge strike or tunnel strike (also known as bridge bashing) is a type of transport accident in which a vehicle collides with a bridge, overpass, or tunnel structure. Bridge-strike road accidents, in which an over-height vehicle collides with the underside of the structure, occur frequently and are a major issue worldwide. In waterways, the term encompasses water vessel–bridge ship collision, collisions, including bridge span and support structure collisions. Impacts In United Kingdom, railway bridge strikes (called "bridge bashing") happen on an average of once every four and a half hours, with total of 1789 times in 2019. Several bridges have been hit over 20 times in a single year. The total cost borne by the state was around £23 million. In Beijing, China, 20% of all bridge damages are caused by bridge strikes. Texas Department of Transportation estimated in 2013 that an average cost to repair a bridge strike is $180,000 USD. Even without damages to the bridges, the strike ...

Truck Driver Ignored Low Clearance Road Signs, Oxley, April 2021
A truck or lorry is a motor vehicle designed to transport freight, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor". The majority of trucks currently in use are powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in North America. Electrically powered trucks are more popular in Chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manual On Uniform Traffic Control Devices
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 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 dimensions, colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Clearance
In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft. In addition, there is the difference between the deep draft and the stream bed or sea bed of a waterway. For roadways and waterways, the clearance is typically specified as the width/height of a structure that the vehicle needs to pass instead of the difference between the vehicle and the structure. Railways In railways, clearance is the difference between the loading gauge and the structure gauge. A clearance standard is established using static rolling stock outline (static gauge) as the starting point. This is a cross-sectional outline of a maximum size rolling stock when it is not run ...

Boksburg
Boksburg is a city on the East Rand of Gauteng province of South Africa. Gold was discovered in Boksburg in 1887. Boksburg was named after the State Secretary of the South African Republic, Willem Eduard Bok, W. Eduard Bok. The R29 (South Africa), Main Reef Road linked Boksburg to all the other major mining towns on the Witwatersrand and the Angelo Hotel (1887) was used as a staging post. Boksburg has been part of the City of Ekurhuleni Metropolitan Municipality since 5 December 2000, which forms the local government of most of the East Rand. The Mining Commissioner Montague White built a large dam which, empty for years, was dubbed White's Folly until a flash flood in 1889 silenced detractors. The 150,000-square-metre dam is now the Boksburg Lake, and is surrounded by lawns, trees, and terraces. History Prior to 1860, the present municipal area of Boksburg and its immediate environs comprised mainly the highveld farms called Leeuwpoort, Klippoortje, Klipfontein and Drie ...

Parkways In New York
The majority of parkways in the US state of New York are part of a statewide parkway system owned by several public and private agencies but mostly maintained by the New York State Department of Transportation (NYSDOT). A handful of other roads in the Hudson Valley and on Long Island are also known as parkways but are not part of the state system. The roads of the state parkway system were among the first expressways to be constructed. These highways were not divided and allowed no driveway cuts, but did have intersections for some of the streets they crossed. A small section of the privately financed Long Island Motor Parkway was the first expressway to begin operation as a toll road and the first highway to use bridges and overpasses to eliminate intersections. The individual parkways vary widely in composition. Some, such as the Sprain Brook Parkway, are functionally equivalent to a freeway; others, like Seven Lakes Drive, are two-lane undivided roads. The majority of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-decker Bus
A double-decker bus is a bus that has two storeys or decks. Double-deckers are used primarily for commuter transport, but open-top models are used as sightseeing buses for tourists, and there are coaches too for long-distance travel. They appear in many places around the world but are presently most commonly used as mass transport in cities of Britain, and in Ireland, China, Hong Kong, Berlin and Singapore. The earliest double-decker horse-drawn omnibus appeared in Paris in 1853 and such vehicles were motorised in the 1900s. Double-decker buses were popularised in Great Britain at the start of the 20th century and today the best-known example is the red London bus, namely the AEC Routemaster. Double-deckers in urban transport were also in common use in other places, such as major cities of India, but were mostly diminished or phased out by the end of the 20th century. However they remain common in Britain as well as Ireland and Hong Kong, while in Singapore and Dhaka they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fracture Critical Bridge
A fracture critical bridge is a bridge or similar span that is vulnerable to collapse of one or more spans as a result of the failure in tension of a single element. While a fracture critical design is not considered unsafe, it is subject to special inspection requirements that focus on the tension elements of its structure. Definition For a bridge to be defined as fracture critical: * It must possess structural members that are subject to tensile stresses from bending or axial forces. * The members must be non-redundant, lacking alternate load paths or means of safely redistributing forces in the event of a tensile failure. While members subject to compressive stress may also fail catastrophically, they typically do not fail from crack initiation. Examples of bridge designs that would typically be considered fracture critical are: * Most truss bridges with two main load-bearing assemblies * Two-beam girder bridges (three-beam bridges in California) * Two-cell steel box girder ...
