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.
99-567: Traffic comprises pedestrians , vehicles , ridden or herded animals, trains, and other conveyances that use public ways (roads/sidewalks) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections . ( International Regulations for Preventing Collisions at Sea govern
198-402: A radar unit) to measure the speed of vehicles, and pull over any vehicle found to be in violation of the speed limit. In Brazil , Colombia and some European countries, there are computerized speed-measuring devices spread throughout the city, which will automatically detect speeding drivers and take a photograph of the license plate (or number plate), which is later used for applying and mailing
297-473: A stop sign at every entrance, called four-way stops. A failed signal or a flashing red light is equivalent to a four-way stop, or an all-way stop . Special rules for four-way stops may include: In Europe and other places, there are similar intersections. These may be marked by special signs (according to the Vienna Convention on Road Signs and Signals ), a danger sign with a black X representing
396-405: A breach to turn, and this might cause inconvenience for drivers that follow them but do not want to turn. This is why dedicated lanes and protected traffic signals for turning are sometimes provided. On busier intersections where a protected lane would be ineffective or cannot be built, turning may be entirely prohibited, and drivers will be required to "drive around the block" in order to accomplish
495-558: A casual basis, with wages around A$ 16 to A$ 25 per hour. In British Columbia, WorkSafeBC regulates the training of Traffic Control Persons (TCPs), stating that TCPs must be trained in a manner acceptable to the Board. This ensures a high level of training for this high-risk occupation. Currently, the only acceptable course in the province is a two-day session which includes theory and practical components. Royal Canadian Mounted Police (RCMP) Superintendent Derek Cooke of Langley believes that
594-478: A concept of a major road and minor road. The default give-way-to-the-right rule used in Continental Europe causes problems for many British and Irish drivers who are accustomed to having right of way by default unless otherwise indicated. A very small proportion of low-traffic junctions are unmarked – typically on housing estates or in rural areas. Here the rule is to "proceed with great care" i.e. slow
693-420: A crossroads. This sign informs drivers that the intersection is uncontrolled and that default rules apply. In Europe and in many areas of North America the default rules that apply at uncontrolled four-way intersections are almost identical: A number of features make this protected intersection . A corner refuge island, a setback crossing of the pedestrians and cyclists, generally between 1.5–7 metres of setback,
792-858: A designated footpath for pedestrian traffic , called the sidewalk in North American English , the pavement in British English , and the footpath in Australian and New Zealand English . There are also footpaths not associated with a road; these include urban short cuts and also rural paths used mainly by ramblers, hikers, or hill-walkers. Footpaths in mountainous or forested areas may also be called trails . Pedestrians share some footpaths with horses and bicycles: these paths may be known as bridleways. Other byways used by walkers are also accessible to vehicles . There are also many roads with no footpath. Some modern towns (such as
891-411: A double white line means that the lane change is prohibited. When a street is wide enough to accommodate several vehicles traveling side-by-side, it is usual for traffic to organize itself into lanes , that is, parallel corridors of traffic. Some roads have one lane for each direction of travel and others have multiple lanes for each direction. Most countries apply pavement markings to clearly indicate
990-500: A forward stop bar, which allows cyclists to stop for a traffic light well ahead of motor traffic who must stop behind the crosswalk. Separate signal staging or at least an advance green for cyclists and pedestrians is used to give cyclists and pedestrians no conflicts or a head start over traffic. The design makes a right turn on red, and sometimes left on red depending on the geometry of the intersection in question, possible in many cases, often without stopping. This type of intersection
1089-399: A frontal impact. In such a situation, an adult pedestrian is struck by a car front (for instance, the bumper touches either the leg or knee-joint area), accelerating the lower part of the body forward while "the upper body is rotated and accelerated relative to the car," at which point the pelvis and thorax are hit. Then the head hits the windscreen at the velocity of the striking car. Finally,

#17327731970691188-467: A high priority in many large cities in Western Europe, often in conjunction with public transport enhancements. In Copenhagen , the world's longest pedestrian shopping area, Strøget , has been developed over the last 40 years, principally due to the work of Danish architect Jan Gehl , a principle of urban design known as copenhagenisation . Safety is an important issue where cars can cross
1287-484: A job, the lowest bid is accepted (except in the case of disadvantaged companies), and the labor is provided to the contractor or agency in charge. Typically speaking, flaggers work in groups of 5 to 10 under a TCS, or Traffic Control Supervisor. The TCS is responsible for placing the flaggers correctly, ensuring that they receive the proper breaks and supervision, and placing the advance warning signs (such as Road Work Ahead, One Lane Road Ahead, and Uneven Lanes). Flaggers are
1386-527: A major road from a smaller road or alley must yield to the traffic of the busier road, but signs are often still posted. The boulevard rule can be compared with the above concept of a major and minor road, or the priority roads that may be found in countries that are parties to the Vienna Convention on Road Signs and Signals. Also known as a "four-way" intersection, this intersection is the most common configuration for roads that cross each other, and
1485-401: A minimum of five years' experience, current "Road Safety Auditor" accreditation and current AWTM accreditation. This qualification is also valid for three years. All employers require drug screening at least annually and often randomly, and many others require daily blood/alcohol tests; some require police clearance checks. Zero tolerance is universal. Traffic controllers are usually employed on
1584-486: A particular road at a busy intersection may be dominant – that is, its traffic flows – until a break in traffic, at which time the dominance shifts to the other road where vehicles are queued. At the intersection of two perpendicular roads, a traffic jam may result if four vehicles face each other side-on. Drivers often seek to turn onto another road or onto private property . The vehicle's blinking turn signals (commonly known as "blinkers" or "indicators") are often used as
1683-496: A phenomenon known as traffic waves . A complete breakdown of organization may result in traffic congestion and gridlock . Simulations of organized traffic frequently involve queuing theory , stochastic processes and equations of mathematical physics applied to traffic flow . The word traffic originally meant "trade" (as it still does) and comes from the Old Italian verb trafficare and noun traffico . The origin of
1782-610: A process of removing vehicular traffic from city streets or restricting vehicular access to streets for use by pedestrians, to improve the environment and safety. Efforts are under way by pedestrian advocacy groups to restore pedestrian access to new developments, especially to counteract newer developments, 20% to 30% of which in the United States do not include footpaths. Some activists advocate large pedestrian zones where only pedestrians, or pedestrians and some non-motorised vehicles, are allowed. Many urbanists have extolled
1881-463: A public road usually has priority over other traffic such as traffic emerging from private access; rail crossings and drawbridges are typical exceptions. Uncontrolled traffic comes in the absence of lane markings and traffic control signals . On roads without marked lanes, drivers tend to keep to the appropriate side if the road is wide enough. Drivers frequently overtake others. Obstructions are common. Intersections have no signals or signage, and
1980-480: A road with no footpath. Indoor pedestrian networks connect the different rooms or spaces of a building. Airports, museums, campuses, hospitals and shopping centres might have tools allowing for the computation of the shortest paths between two destinations. Their increasing availability is due to the complexity of path finding in these facilities. Different mapping tools, such as OpenStreetMap , are extending to indoor spaces. Pedestrianisation might be considered as
2079-418: A simple diversion or closure of a cul-de-sac, up to multiple two- or three-person crews for a complex task. One example of such a complex task is the transport of very wide loads taking all available roadspace, over several kilometers, usually on an arterial road or highway. In these cases, the affected roads can be closed or contraflowed for the entire day, creating enormous disruption to motorists. Management of
SECTION 20
#17327731970692178-425: A vehicle. The Traffic Injury Research Foundation describes pedestrians as vulnerable road users because they are not protected in the same way as occupants of motor vehicles. There is an increasing focus on pedestrians versus motor vehicles in many countries. Most pedestrian injuries occur while they are crossing a street. Most crashes involving a pedestrian occur at night. Most pedestrian fatalities are killed by
2277-405: A way to announce one's intention to turn, thus alerting other drivers. The actual usage of directional signals varies greatly amongst countries, although its purpose is to indicate a driver's intention to depart from the current (and natural) flow of traffic well before the departure is executed (typically 3 seconds as a guideline). This will usually mean that turning traffic must stop and wait for
2376-524: A worksite by speed reinstatement and a " End Roadworks " signs. The worksite will usually involve closing a part of the road for the work area. How this is done depends on the type of road: on a multi-lane road, one or more lanes will be closed off and traffic merged into the remaining lane(s), using cones and " Chevron " signs and Arrow Boards to guide motorists. On a wide road (more than 3 meters per lane in Australia), traffic could be "diverted" around
2475-457: Is guilty of a misdemeanor simply for travelling 5 miles over the speed limit. Trail ethics are a set of informal rules for right of way for users of trails , including hikers, mountaineers, equestrians, cyclists, and mountain bikers. Vehicles often come into conflict with other vehicles and pedestrians because their intended courses of travel intersect, and thus interfere with each other's routes. The general principle that establishes who has
2574-562: Is a footbridge . In Britain, regardless of whether there is a footpath, pedestrians have the legal right to use most public roads, excluding motorways and some toll tunnels and bridges such as the Blackwall Tunnel and the Dartford Crossing — although sometimes it may endanger the pedestrian and other road users. The UK Highway Code advises that pedestrians should walk in the opposite direction to oncoming traffic on
2673-438: Is allowed past the work area in turn. For works in high-speed or dangerous areas (decided by the local governing body) portable traffic lights or boom-gates may be used to remove the traffic controller from the danger of being struck by a car. At signalised intersections, it may be necessary to have the traffic lights disabled. When this occurs, police are deployed to control the intersection. Sometimes on dual carriageways, it
2772-466: Is common for drivers to observe (and trust) the turn signals used by other drivers in order to make turns from other lanes. If several vehicles on the right lane are all turning right, a vehicle may come from the next-to-right lane and turn right as well, in parallel with the other right-turning vehicles. In most of Continental Europe , the default rule is to give priority to the right , but this may be overridden by signs or road markings. There, priority
2871-437: Is common in the bicycle-friendly Netherlands . Pedestrians must often cross from one side of a road to the other, and in doing so may come into the way of vehicles traveling on the road. In many places pedestrians are entirely left to look after themselves, that is, they must observe the road and cross when they can see that no traffic will threaten them. Busier cities usually provide pedestrian crossings , which are strips of
2970-469: Is complex and extensive. Traffic volumes, types of vehicles, driving styles, population density, speed limits, and many other factors vary dramatically from one region to the next. As a result, highway traffic control measures (including type of equipment and implementation), are not strictly consistent. Federal Guidelines do not address certification methods for traffic controllers, flaggers, or other personnel responsible for traffic control. This responsibility

This word is derived from the Latin term pedester ('going on foot') and was first used (in the English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks. The word pedestrian may have been used in middle French in

Clothing is considered part of PPE —personal protective equipment—which includes steel-capped boots, sunscreen, broad-brim hats, gloves and sunglasses. The traffic control process usually starts with a traffic control plan. A traffic control crew may consist of one person running

Traffic control is governed by the Australian Standard AS 1742.3 – 2009, and by State variations. Risk management is regulated under AS/NZS 4360:1999. Traffic controllers are required to wear high-visibility clothing which meets the Australian Standard AS/NZS 4602:1999. Personal safety
3366-569: Is generally expected to move to the lane closest to the direction they wish to turn. For example, traffic intending to turn right will usually move to the rightmost lane before the intersection. Likewise, left-turning traffic will move to the leftmost lane. Exceptions to this rule may exist where for example the traffic authority decides that the two rightmost lanes will be for turning right, in which case drivers may take whichever of them to turn. Traffic may adapt to informal patterns that rise naturally rather than by force of authority. For example, it

A road may have a high-visibility jacket wearing traffic controller, a Crossing Guard (colloquially a "lollipop man" or "lollipop woman") who aids children in crossing on their journey to school or a Stop / Go Marshall, ( Traffic Guard ) at temporary road works. Responsibility is with
3564-572: Is greater than 40 km/h. Among the factors which reduce road safety for pedestrians are wider lanes, roadway widening, and roadways designed for higher speeds and with increased numbers of traffic lanes. For this reason, some European cities such as Freiburg (Germany) have lowered the speed limit to 30 km/h on 90% of its streets, to reduce risk for its 15 000 people. With such policy, 24% of daily trips are performed by foot, against 28% by bicycles, 20% by public transport and 28% by car. (See Zone 30 .) A similar set of policies to discourage
3663-583: Is important both for human health and for the natural environment . Frequent exercise such as walking tends to reduce the chance of obesity and related medical problems. In contrast, using a car for short trips tends to contribute both to obesity and via vehicle emissions to climate change: internal combustion engines are more inefficient and highly polluting during their first minutes of operation (engine cold start). General availability of public transportation encourages walking, as it will not, in most cases, take one directly to one's destination. In Unicode ,

This cannot be done "on the fly", as high-speed (100-plus km/h), high-volume (500–1,000+ vehicles per hour) traffic is involved, generating a huge risk to workers. In this case advisory signs will be erected weeks or even months in advance, and new lanes defined by bollards anchored firmly to the road-base will be installed, usually at night when traffic

However, older people are often valued by employers for their life experience, and find that the relatively light manual labour compensates for the discomforts and rigours of the job. There is a career path, but it is dictated by one's own ability and willingness to work. Accreditation course standards and variations to

In the United Kingdom and Canada, notably on extra-urban roads, a solid white or yellow line closer to the driver is used to indicate that no overtaking is allowed in that lane. A double white or yellow line means that neither side may overtake. In the United States, a solid white line means that lane changes are discouraged and

4851-563: The traffic signal is used to establish the right of way on the busy roads. Its primary purpose is to give each road a duration of time in which its traffic may use the intersection in an organised way. The intervals of time assigned for each road may be adjusted to take into account factors such as difference in volume of traffic, the needs of pedestrians, or other traffic signals. Pedestrian crossings may be located near other traffic control devices; if they are not also regulated in some way, vehicles must give priority to them when in use. Traffic on

Other drivers simply do not pay enough attention to the road, often from using their mobile (cell-) phones, or because they are tired from a night shift at work. Not a few are exceeding the posted speed limit. Typically, a worksite will be set up with warning signage well in advance of

Driving cultures vary greatly on
7227-528: The location. These default priority rules differ between countries, and may even vary within countries. Trends toward uniformity are exemplified at an international level by the Vienna Convention on Road Signs and Signals , which prescribes standardised traffic control devices (signs, signals, and markings) for establishing the right of way where necessary. Crosswalks (or pedestrian crossings) are common in populated areas, and may indicate that pedestrians have priority over vehicular traffic. In most modern cities,

Traffic is formally organized in many jurisdictions, with marked lanes , junctions , intersections , interchanges , traffic signals , cones , or signs . Traffic is often classified by type: heavy motor vehicle (e.g., car , truck ), other vehicle (e.g., moped , bicycle ), and pedestrian . Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of
7623-445: The pedestrian must push a button in order to assert their intention to cross. In some countries, approaching traffic is monitored by radar or by electromagnetic sensors buried in the road surface, and the pedestrian crossing lights are set to red if a speed infringement is detected. This has the effect of enforcing the local speed limit. See Speed Limits below. Pedestrian crossings without traffic signals are also common. In this case,
7722-481: The pedestrian way. Drivers and pedestrians share some responsibility for improving safety of road users. Road traffic crashes are not inevitable; they are both predictable and preventable. Key risks for pedestrians are well known. Among the well-documented factors are driver behaviour (including speeding and drunk driving); infrastructure missing facilities (including pavements, crossings and islands ); and vehicle designs which are not forgiving to pedestrians struck by
7821-781: The recommended maximum speed is 30 km/h (20 mph) or 40 km/h (25 mph) in residential and high pedestrian traffic areas, with enforced traffic rules on speed limits and traffic-calming measures. The design of road and streets plays a key role in pedestrian safety. Roads are too often designed for motorized vehicles, without taking into account pedestrian and bicycle needs. The non-existence of sidewalk and signals increases risk for pedestrians. This defect might more easily be observed on arterial roadways, intersections and fast-speed lanes without adequate attention to pedestrian facilities. For instance, an assessment of roads in countries from many continents shows that 84% of roads are without pedestrian footpaths, while maximum limited speed
7920-405: The right to go first is called "right of way" or "priority". It establishes who has the right to use the conflicting part of the road and who has to wait until the other does so. Signs, signals, markings and other features are often used to make priority explicit. Some signs, such as the stop sign , are nearly universal. When there are no signs or markings, different rules are observed depending on
8019-512: The road where pedestrians are expected to cross. The actual appearance of pedestrian crossings varies greatly, but the two most common appearances are: (1) a series of lateral white stripes or (2) two longitudinal white lines. The former is usually preferred, as it stands out more conspicuously against the dark pavement. Some pedestrian crossings accompany a traffic signal to make vehicles stop at regular intervals so pedestrians can cross. Some countries have "intelligent" pedestrian signals, where
8118-404: The road while others rely more on drivers' common sense and willingness to cooperate. Organization typically produces a better combination of travel safety and efficiency. Events which disrupt the flow and may cause traffic to degenerate into a disorganized mess include road construction , collisions , and debris in the roadway . On particularly busy freeways, a minor disruption may persist in
8217-506: The road. Drivers are usually expected to keep in the slowest lane unless overtaking , though with more traffic congestion all lanes are often used. Pedestrian A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement (US: sidewalk), but this was not the case historically. Pedestrians may also be wheelchair users or other disabled people who use mobility aids . The meaning of pedestrian
8316-439: The roads meet at approximate right angles. The United Kingdom and Croatia are among the exceptions. Pedestrian crossings may also be located away from intersections. A level crossing is an at-grade intersection of a railway by a road. Because of safety issues, they are often equipped with closable gates , crossing bells and warning signs. The higher the speed of a vehicle, the more difficult collision avoidance becomes and
8415-490: The same road (unless there were multiple lanes, but then one must take care in case a vehicle jumped lanes). New Zealand abolished this particular rule on 25 March 2012, except at roundabouts or when denoted by a Give Way or Stop sign. Although the rule caused initial driver confusion, and many intersections required or still require modification, the change is predicted to eventually prevent one death and 13 serious injuries annually. On roads with multiple lanes, turning traffic
8514-634: The setup of signs, cones etc., and making sure the setup complies with the NS Temporary Workplace Traffic Control Manual . All flag persons—or traffic control persons (TCP)—in Newfoundland and Labrador are now required to complete a TCP training course approved by the Workplace Health, Safety and Compensation Commission. Proper traffic control is critical for the safety of workers, drivers and
8613-409: The site of 46% of all pedestrian deaths in the country. The advent of SUVs is considered a leading cause; speculation of other factors includes population growth, driver distraction with mobile phones, poor street lighting, alcohol and drugs and speeding. Cities have had mixed results in addressing pedestrian safety with Vision zero plan: Los Angeles fails while NYC has had success. Nonetheless, in
8712-597: The states and municipalities through their respective traffic codes . Most of these are based at least in part on the Uniform Vehicle Code , but there are variations from state to state. In states such as Florida, traffic law and criminal law are separate; therefore, unless someone flees the scene of an accident or commits vehicular homicide or manslaughter, they are only guilty of a minor traffic offense. However, states such as South Carolina have completely criminalised their traffic law, so, for example, one
8811-504: The ticket. Many jurisdictions in the U.S. use this technology as well. A mechanism that was developed in Germany is the Grüne Welle , or green wave , which is an indicator that shows the optimal speed to travel for the synchronized green lights along that corridor. Driving faster or slower than the speed set by the behavior of the lights causes the driver to encounter many red lights. This discourages drivers from speeding or impeding
8910-405: The traffic laws usually states that the pedestrian has the right of way when crossing, and that vehicles must stop when a pedestrian uses the crossing. Countries and driving cultures vary greatly as to the extent to which this is respected. In the state of Nevada the car has the right of way when the crosswalk signal specifically forbids pedestrian crossing. Traffic culture is a determinant factor for
9009-724: The turn. Many cities employ this tactic quite often; in San Francisco, due to its common practice, making three right turns is known colloquially as a "San Francisco left turn". Likewise, as many intersections in Taipei City are too busy to allow direct left turns, signs often direct drivers to drive around the block to turn. Turning rules are by no means universal. For example, in New Zealand (a drive-on-the-left country) between 1977 and 2012, left turning traffic had to give way to opposing right-turning traffic wishing to take
9108-428: The union has their own transport regulator. The four countries within the UK adhere to the same standards for most traffic control and temporary modifications to traffic and pedestrian control, such as street works and road works (sometimes referred to as the "Red Book"): Safety at Street Works and Road Works – A Code of Practice . Before permission for non-police temporary traffic control (beyond emergency closure)
9207-605: The use of cars and increase safety for pedestrians has been implemented by the Northern European capitals of Oslo and Helsinki. In 2019, this resulted in both cities counting zero pedestrian deaths for the first time. In Europe, pedestrian fatalities have a seasonal factor, with 6% of annual fatalities occurring in April but 13% (twice more) in December. The rationale for such a change might be complex. Regular walking
9306-418: The vehicle and check for traffic on the intersecting road. Other countries use various methods similar to the above examples to establish the right of way at intersections. For example, in most of the United States, the default priority is to yield to traffic from the right, but this is usually overridden by traffic control devices or other rules, like the boulevard rule . This rule holds that traffic entering
9405-438: The victim falls to the ground. Research has shown that urban crimes, or the mere perception of crimes, severely affect the mental and physical health of pedestrians. Inter-pedestrian behaviour, without the involvement of vehicles, is also a key factor to pedestrian safety. Some special interest groups consider pedestrian fatalities on American roads a carnage. Five states – Arizona, California, Florida, Georgia and Texas – are
9504-533: The virtues of pedestrian streets in urban areas. In the US the proportion of households without a car is 8%, but a notable exception is New York City , the only locality in the United States where more than half of all households do not own a car (the figure is even higher in Manhattan, over 75%). The use of cars for short journeys is officially discouraged in many parts of the world, and construction or separation of dedicated walking routes in city centres receives
9603-444: The work area by using cones to define a new road centerline and another line of cones around the work area to create what is called a contraflow . Sometimes, it is necessary to close a road and detour traffic. Often, the road is not wide enough to permit opposing streams of traffic past the work area. Then it is necessary to use traffic controllers holding " Stop/Slow" Paddles or Bats to enact shuttle flow operations, where each stream
9702-460: Was initially given according to the social rank of each traveler, but early in the life of the automobile this rule was deemed impractical and replaced with the priorité à droite (priority to the right) rule, which still applies. At a traffic circle where priorité à droite is not overridden, traffic on what would otherwise be a roundabout gives way to traffic entering the circle. Most French roundabouts now have give-way signs for traffic entering
9801-546: Was non a popular spectator sport, just as equestrianism (riding) still is in places. One of the most famous pedestrians of that period was Captain Robert Barclay Allardice , known as "The Celebrated Pedestrian", of Stonehaven in Scotland. His most impressive feat was to walk 1 mile (1.6 km) every hour for 1000 hours, which he achieved between 1 June and 12 July 1809. This feat captured many people's imagination, and around 10,000 people came to watch over
