Van Brienenoordbrug
The Van Brienenoord Bridge (Dutch: ''Van Brienenoordbrug'') is a large twin tied-arch motorway bridge in the Netherlands. Located at the east side of Rotterdam, it crosses the New Meuse (''Nieuwe Maas''), a major distributary of the river Rhine. The bridge actually consists of two separate, parallel, and (visually) almost identical arch-bridges, as well as a set of three parallel bascule bridges on the north end. The bridge carries 12 lanes of traffic of the A16 motorway, the busiest highway in the Netherlands. Additionally, on the outside of the east arch, a two-way segregated cycling bridge has been mounted. Including lead-up ramps, the Van Brienenoord Bridge is 1320 metres long and vessels with up to 24 metres air draft can pass under the closed bridge. With a span of 300 m, the west arch is the longest span road bridge in the Netherlands. Traffic exceeds 235,000 vehicles crossing the bridge daily, using four 3-lane carriageways, in an express versus local / distributor ...

Van Brienenoordbrug Sept 2004
A van is a type of road vehicle used for transporting goods or people. Depending on the type of van, it can be bigger or smaller than a pickup truck and SUV, and bigger than a common car. There is some varying in the scope of the word across the different English-speaking countries. The smallest vans, microvans, are used for transporting either goods or people in tiny quantities. Mini MPVs, compact MPVs, and Multi-purpose vehicle, MPVs are all small vans usually used for transporting people in small quantities. Larger vans with passenger seats are used for institutional purposes, such as transporting students. Larger vans with only front seats are often used for business purposes, to carry goods and equipment. Specially-equipped vans are used by television stations as mobile studios. Postal services and courier companies use large step vans to deliver packages. Word origin and usage Van meaning a type of vehicle arose as a contraction of the word Caravan (towed trailer), carava ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traffic Jam
Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion. While congestion is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics. Causes Traffic congestion occurs when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bascule Bridges
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed. The name comes from the French term for balance scale, which employs the same principle. Bascule bridges are the most common type of movable span because they open quickly and require relatively little energy to operate, while providing the possibility for unlimited vertical clearance for marine traffic. History Bascule bridges have been in use since ancient times, but until the adoption of steam power in the 1850s, very long, heavy spans could not be moved quickly enough for practical application. Types There are three types of bascule bridge and the counterweights to the span may be located above or below the bridge deck. The fixed-trunnion (sometimes a "Chicago" bascule) rotates around a large axle that raises the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tied Arch Bridges
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends. Description Thrusts downwards on a tied-arch bridge deck are translated, as tension, by vertical ties between the deck and the arch, tending to flatten it and thereby to push its tips outward into the abutments, like for other arch bridges. However, in a tied-arch or bowstring bridge, these movements are restrained not by the abutments but by the strengthened chord, which ties these tips together, taking the thrusts as tension, rather like the string of a bow that is being flattened. Therefore, the design is also called a bowstring-arch or bowstring-girder bridge. The elimination o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willemsbrug
The Willemsbrug (English: "Williams Bridge") is a bridge next to the Erasmusbrug in the centre of Rotterdam, Netherlands, spanning the Nieuwe Maas. It links the northern part of the city with the ''Noordereiland'' and (in combination with the Koninginnebrug) the district of ''Feijenoord''. The bridge was completed in 1981, designed by C. Veerling and named after King Willem III of the Netherlands. It replaced an older bridge that had been opened in 1879 but was severely outdated by the time the decision was made to build a new one. Because of the intensity of the traffic using the old bridge, it was decided to build the new one 150 metres upstream to avoid upsetting the daily flow of traffic across the river. After the completion of the new bridge, the old one was demolished. The Willemsbrug is a cable-stayed bridge A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays ...

Vianen
Vianen () is a city and a former municipality in the central Netherlands, in the province of Utrecht. It is located south of the Lek River. Before 2002 it was part of the province of South Holland. Vianen is made up of a historic town centre that dates back to the medieval period and was once surrounded by a defensive wall (parts of which still stand today) and moat, as well as more extensive modern housing developments to the east, south and southwest and an industrial and commercial area. Vianen is intersected by two major motorways leading to Utrecht: the A2 (Amsterdam-Maastricht) and the A27 (Breda-Almere). Both roads can be notoriously congested near Vianen during peak commute hours. The municipality was merged with the municipalities of Leerdam and Zederik on 1 January 2019. The name of the new municipality is Vijfheerenlanden which is a part of the province Utrecht. The city of Vianen Vianen received city rights in 1337. Vianen thrived under the counts of Brederode, ...

Lek River
The Lek () is a river in the western Netherlands of some in length. It is the continuation of the Nederrijn after the Kromme Rijn branches off at the town of Wijk bij Duurstede. The main westbound waterway is hereafter called the Lek River. The Nederrijn is, itself, a distributary branch of the river Rhine. Portions of the river form the boundary between the provinces of Utrecht and Gelderland, and between Utrecht and South Holland. In Roman times, the Nederrijn flowed into the Kromme Rijn and these streams were the main outflow of the river Rhine. When the Kromme Rijn began to silt up in the Middle Ages, the Lek became the primary branch. A short distance past Wijk bij Duurstede, the river intersects with the Amsterdam-Rhine Canal, which continues south towards the Waal. A branch of this canal, the ''Lekkanaal'' (Lek Canal) is connected to the river at the city of Nieuwegein. Other major towns on its banks are Culemborg, Vianen, Schoonhoven, Nieuw-Lekkerland, Lekkerkerk and Kr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...
