Bus Trap
A bus trap (car trap in the UK) is a metal grate placed over a ditch or pit in the road with tines (sides) spaced far enough apart that small (shorter axle) vehicles fall between the tines but close enough that larger-diameter-wheeled vehicles, such as buses, may pass. Cycles may cross broader sided examples. Different versions exist for restricting access. The tines cross the path of the road, not parallel with the road direction. Small-wheeled vehicles bottom out in between the tines, preventing the vehicle from continuing over the obstacle. Deprecation and preferred alternatives Many domestic vehicles exist in the 21st century wide enough to navigate bus traps effectively, including wide-axle SUVs and 4x4s. Police cars and in some cases motorbikes are hindered by bus traps. Most cities favour other means of keeping cars out of bus-only areas, such as: *fines backed up with camera enforcement *a controlled barrier, such as a rising clearly marked bollard kept in a default ...

Skejby Busvej 05
Skejby is a neighbourhood and former village in Aarhus, Denmark. The neighbourhood is part of the city district Aarhus N. The Skejby village was originally situated in the countryside north of Aarhus, overlooking the broad flat Egå Valley, but urban development has engulfed it, creating a new suburban neighbourhood by the same name. The old village is still distinctly visible, surrounding the old white village church. Archaeological excavations have revealed, that Skejby has been settled since the early Iron Ages (c. 500 BC), but finds from the Stone Age has also been unearthed.

Bollard
A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. It now also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures, whether intentional from ram-raids and vehicle-ramming attacks, or unintentional losses of control. Etymology The term is probably related to bole, meaning a tree trunk. The earliest citation given by the ''Oxford English Dictionary'' (referring to a maritime bollard) dates from 1844, although a reference in the ''Caledonian Mercury'' in 1817 describes bollards as huge posts. History Wooden posts were used for basic traffic management from at least the beginning of the 18th century. An early well-documented case is that of the "two oak-posts" set up next to the medieval Eleanor cross at Waltham Cross, Hertfordshire, in 1721, at the expense of the Society of Antiqua ...

Radio-frequency Identification
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For example, an RFID tag attached to an automobile during production can be used to track ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sump Buster
A sump buster is a device installed within a bus route to limit that thoroughfare to buses. It discourages traffic from entering a lane by promising to destroy the oil pan of any vehicle with insufficient ground clearance to get over it, making them similar in use (but not design) to rising bollards. A sump buster can also be known as a "sump breaker" or "sump trap". Sump busters were first used in the 1980s.Lodder, Arno R., and Bart Verheij.13th BILETA Conference:'The Changing Jurisdiction." Function The sump buster uses a non-mechanical solid mass of concrete, or sometimes other aggregates or metal, to demobilise a vehicle when access to a restricted area is attempted. When a vehicle attempts to traverse the sump buster, the device will demolish the vehicle's oil pan (literally "busting the sump"). The track and ground clearance on permitted vehicles, usually buses, is such that they may clear the device with ease. In some cases, advisory or mandatory speed limits are given. ...

Cattle Grid
A cattle grid – also known as a stock grid in Australia; cattle guard, or cattle grate in American English; vehicle pass, or stock gap in the Southeastern United States; Texas gate in western Canada and the northwestern United States; and a cattle stop in New Zealand English – is a type of obstacle used to prevent livestock, such as sheep, cattle, pigs, horses, or mules from passing along a road or railway which penetrates the fencing surrounding an enclosed piece of land or border. It consists of a depression in the road covered by a transverse grid of bars or tubes, normally made of metal and firmly fixed to the ground on either side of the depression, so that the gaps between them are wide enough for an animal's feet to enter, but sufficiently narrow not to impede a wheeled vehicle or human foot. This provides an effective barrier to animals without impeding wheeled vehicles, as the animals are reluctant to walk on the grates. Origins The modern cattle grid for roads u ...
