Road Works
Roadworks, also called road construction or road work, occur when part of the road, or in rare cases, the entire road, has to be occupied for work relating to the road, most often in the case of road surface repairs. In the United States road work could also mean any work conducted in close proximity of travel way ( thoroughfare) such as utility work or work on power lines (i.e. telephone poles). The general term of road work is known as work zone. Roadworks can, however, also happen when a major accident occurs and road debris from the crash needs to be cleared. Roadworks are often signposted, although it is possible that the signage comes too late or too sudden or is missing. Typical road work traffic controls are temporary signs, traffic cones, barrier boards and t-top bollards as well as other forms of warning devices. There are standards of temporary traffic control established in each country for various type of road work. Usually, roadworks takes place at night, b ...

Maintenance Of Traffic
Maintenance of traffic (MOT), also known as temporary traffic control or temporary traffic management, is a process of establishing of a work zone, providing related transportation management and temporary traffic control on streets and highways right-of-way. This process does not apply to law enforcement officers. The establishment of a work zone and management of temporary traffic control is conducted by traffic controllers, also known as flaggers, traffic observers, or spotters. Standards of operations are established by the department of transportation of each state, and may vary from state to state. Temporary Traffic Control or Temporary Traffic Management is critical to maintaining safety and minimizing disruption during temporary work zones, events, and other short-term traffic disruptions. In the United States, traffic control devices are set up according to the Manual on Uniform Traffic Control Devices, sometimes along with state supplements. Maintenance of traffic tr ...

Smart Work Zone
A smart work zone or intelligent work zone refers to a site-specific configuration of traffic control technology deployed within a roadway work zone to increase the safety of construction workers, provide "real-time" travel information, and efficiently route motorists through a work zone. Smart work zones reduce the dependency on human "flaggers" and make the work zone safer for roadway workers. Common terms used to describe equipment configuration used within smart work zones: Smart work zones often use radar gun A radar speed gun, also known as a radar gun, speed gun, or speed trap gun, is a device used to measure the speed of moving objects. It is commonly used by police to check the speed of moving vehicles while conducting Traffic police, traffic enf ...s or other non-intrusive sensors to detect the presence and speed of vehicles approaching a work zone, in order to display an appropriate message on one or more variable message signs. In a "dynamic merge" s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The reasons for one could be: * Roadworks *Temporary road closure during special events * Police chase *Robbery * Sobriety checkpoint * Protests In peaceful circumstances, they are usually installed by the police or road transport authorities; they are also commonly employed during wars and are usually staffed by heavily armed soldiers in that case. During protests and riots, both police and demonstrators sometimes use roadblocks. 1 Global Bus. L. Rev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Traffic Control
: ''For the road traffic science, see various articles under :Road traffic management, Road traffic management.'' Road traffic control involves directing vehicular and pedestrian traffic around a construction zone, accident or other road disruption, thus ensuring the safety of emergency response teams, construction workers and the general public. Traffic control also includes the use of CCTV and other means of monitoring traffic by local or state roadways authorities to manage traffic flows and providing advice concerning traffic congestion. Traffic Control Technicians (TCTs) or Traffic Control Supervisors (TCSs) are often known as "lollipop men" (usually this name only applies to TCTs working near schools to aid pupils in road crossing) from the appearance of their ''Stop/Slow'' signs, known as "Stop bats". Overview Road Traffic control is an outdoors occupation, night or day for long hours in all weathers, and is considered a dangerous occupation due to the high risk of being ...

Concrete Pavement Restoration
Concrete pavement restoration (CPR) together with concrete pavement preservation (CPP) is a group of various techniques used to maintain concrete roadways. Techniques CPP and CPR techniques include slab stabilization, full- and partial-depth repair, dowel bar retrofit, cross stitching longitudinal cracks or joints, diamond grinding and joint and crack resealing. CPP and CPR methods, developed over the last 40 years, are used in lieu of asphalt overlays and bituminous patches to repair roads when longer lasting solutions are desired. When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. Due to rising oil prices, these methods are often less expensive than an asphalt overlay and last three times longer in addition to providing a greener, more sustainable solution. A recent study was conducted that shows that diamond grinding is an effective means of extending the service life of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vienna Convention On Road Signs And Signals
The Convention on Road Signs and Signals, commonly known as the Vienna Convention on Road Signs and Signals, is a multilateral treaty to standardize the signing system for road traffic (road signs, traffic lights and road markings) in use internationally. History The Convention on Road Signs and Signals was agreed upon by the United Nations Economic and Social Council at its Conference on Road Traffic in Vienna 7 October to 8 November 1968, was concluded in Vienna on 8 November 1968, and entered into force on 6 June 1978. This conference also produced the Vienna Convention on Road Traffic, which complements this legislation by standardising international traffic laws. The convention revised and substantially extended the earlier 1949 Geneva Protocol on Road Signs and Signals, itself based in turn on the 1931 Geneva Convention concerning the Unification of Road Signals. Amendments, including new provisions regarding the legibility of signs, priority at roundabouts, and new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Highway Administration
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. History Background With the coming of the bicycle in the 1890s, interest grew regarding the improvement of streets and roads in America. The traditional method of putting the burden on maintaining roads on local landowners was increasingly inadequate. In 1893, the federal Office of Road Inquiry (ORI) was founded; in 1905, it was renamed the Office of Public Roads (OPR) and made a division of the United States Department of Agriculture. Demands grew for local and state government to take charge. With the coming of the automobile, urgent efforts were made to upgrade and moderniz ...

Manual Of 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, colors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
