Traffic obstruction is a common tactic used during public protests and demonstrations. [1] [2] The transport users affected by such disruptions are sometimes unsympathetic to the cause. [3] [4] [5] [ failed verification ] [6]
Most jurisdictions[ which? ] consider the obstruction of traffic an illegal activity and have developed rules to prosecute those who block, obstruct, impede, or otherwise interfere with the normal flow of vehicular or pedestrian traffic upon a public street or highway. [7] Some jurisdictions also penalize slow moving vehicle traffic. [8] The unimpeded flow of traffic in the public road-space is often considered a common right. [ citation needed ]
Examples of intentional traffic obstructions aimed to articulate a protest agenda include Extinction Rebellion protests, [9] air traffic controller strike, highway revolts, Critical Mass bicycle rides corking intersections, obstruction of rail transport of nuclear fuel in Germany, road blockades by farmers or truckers in France and other countries, impact on Eurotunnel operations by the Migrant Crisis around Calais, pipeline protests (e.g. Dakota Access Pipeline), etc. [ citation needed ]
Raasta roko (Hindi for obstruct the road) is a form of protest commonly practised in India. [10] It usually involves large numbers of people preventing vehicular traffic from using a busy thoroughfare. Pedestrian traffic is not targeted.
Rail roko is similar blocking of a railway. [11]
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles and pedestrians. Unlike streets, the main function of roads is transportation.
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation.
A roundabout is a type 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.
Since Bangladesh's independence in 1971, the transportation sector has grown rapidly and transportation medium on land and rivers have begun to develop. Air travel came into existence later. Though Bangladesh has greatly evolved in the transportation sector, it still has many flaws which hamper the development of other economic and social sectors. Transportation has evolved in mostly land vehicles but it still needs improvement in safety standards, which endangers the life of civilians.
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.
A pedestrian crossing is a place designated for pedestrians to cross a road, street or avenue. The term "pedestrian crossing" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic.
Traffic lights, traffic signals, or stoplights – known also as robots in South Africa are signalling devices positioned at road intersections, pedestrian crossings, and other locations in order to control flows of traffic.
A level crossing is an intersection where a railway line crosses a road, path, or airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing, grade crossing or railroad crossing, road through railroad, criss-cross, train crossing, and RXR (abbreviated).
A street is a public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic.
An overpass is a bridge, road, railway or similar structure that crosses over another road or railway. An overpass and underpass together form a grade separation. Stack interchanges are made up of several overpasses.
Jaywalking is the act of pedestrians walking in or crossing a roadway that has traffic, other than at a designated crossing point, or otherwise, in disregard of traffic rules. The term originated in the United States as a derivation of the phrase jay-drivers, people who drove horse-drawn carriages and automobiles on the wrong side of the road, before taking its current meaning. Jaywalking was coined as the automobile arrived in the street in the context of the conflict between pedestrian and automobiles, more specifically the nascent automobile industry.
The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. designed it and supervised construction of what became the first bridge to span a major river west of the Appalachian mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements applied in later years until it was closed to automobile traffic in September 2019.
A body of water, such as a river, canal or lake, is navigable if it is deep, wide and calm enough for a water vessel to pass safely. Such a navigable water is called a waterway, and is preferably with few obstructions against direct traverse that needed avoiding, such as rocks, reefs or trees. Bridges built over waterways must have sufficient clearance. High flow speed may make a channel unnavigable due to risk of ship collisions. Waters may be unnavigable because of ice, particularly in winter or high-latitude regions. Navigability also depends on context: a small river may be navigable by smaller craft such as a motorboat or a kayak, but unnavigable by a larger freighter or cruise ship. Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level, or by dredging that deepens parts of the stream bed.
The Outer Ring Road is a 6-lane ring road that encircles the city of Delhi. It has three lanes in each direction, with a total length of 47 km. Although it used to have traffic lights and at-grade intersections, mushrooming interchanges have reduced the number of lights to just two, and traffic now flows much more smoothly. Several stretches of the Outer Ring Road have been notified as National Highways.
One-way traffic is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typically result in higher traffic flow as drivers may avoid encountering oncoming traffic or turns through oncoming traffic. Residents may dislike one-way streets due to the circuitous route required to get to a specific destination, and the potential for higher speeds adversely affecting pedestrian safety. Some studies even challenge the original motivation for one-way streets, in that the circuitous routes negate the claimed higher speeds.
A subway, also known as an underpass, is a grade-separated pedestrian crossing which crosses underneath a road or railway in order to entirely separate pedestrians and cyclists from motor traffic or trains respectively.
A roadblock is a temporary installation set up to control or block traffic along a road.
Automatic block signaling (ABS), spelled automatic block signalling or called track circuit block (TCB) in the UK, is a railroad communications system that consists of a series of signals that divide a railway line into a series of sections, called blocks. The system controls the movement of trains between the blocks using automatic signals. ABS operation is designed to allow trains operating in the same direction to follow each other in a safe manner without risk of rear-end collision.
A shared-use path, mixed-use path or multi-use pathway is a path which is 'designed to accommodate the movement of pedestrians and cyclists'. Examples of shared-use paths include sidewalks designated as shared-use, bridleways and rail trails. A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate. Shared-use paths differ from cycle tracks and cycle paths in that shared-use paths are designed to include pedestrians even if the primary anticipated users are cyclists.
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
