A pedestrian is a person traveling on foot, whether walking or running.[ citation needed ] In modern times, the term usually refers to someone walking on a road or pavement (US: sidewalk), but this was not the case historically.[ citation needed ] Pedestrians may also be wheelchair users or other disabled people who use mobility aids.

Etymology

The meaning of pedestrian is displayed with the morphemes ped- ('foot') and -ian ('characteristic of'). [2] This word is derived from the Latin term pedester ('going on foot') and was first used (in the English language) during the 18th century. [3] It was originally used, and can still be used today, as an adjective meaning plain or dull. [4] 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 the Recueil des Croniques et Anchiennes Istories de la Grant Bretaigne . [5]

History

Walking has always been the primary means of human locomotion. The first humans to migrate from Africa, about 60,000 years ago, walked. [6] They walked along the coast of India to reach Australia. They walked across Asia to reach the Americas, and from Central Asia into Europe.

With the advent of the cars at the beginning of the 20th century, the main story is that the cars took over, and "people chose the car", but there were many groups and movements that held on to walking as their preferred means of daily transport and some who organised to promote walking, and to counterbalance the widely-held view that often favoured cars, e.g. as related by Peter Norton. [7]

During the 18th and 19th centuries, pedestrianism (walking) was 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 the course of the event. During the rest of the 19th century, many people tried to repeat this feat, including Ada Anderson who developed it further and walked a half-mile (800 m) each quarter-hour over the 1000 hours.

Since the 20th century, interest in walking as a sport has dropped. Racewalking is still an Olympic sport, but fails to catch public attention as it did. However major walking feats are still performed, such as the Land's End to John o' Groats walk in the United Kingdom, and the traversal of North America from coast to coast. The first person to walk around the world was Dave Kunst who started his walk traveling east from Waseca, Minnesota on 20 June 1970 and completed his journey on 5 October 1974, when he re-entered the town from the west. These feats are often tied to charitable fundraising and are undertaken, among others, by celebrities such as Sir Jimmy Savile and Ian Botham.

Roads often have 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 the new suburbs of Peterborough in England) are designed with the network of footpaths and cycle paths almost entirely separate from the road network.

The term trail is also used by the authorities in some countries to mean any footpath that is not attached to a road or street. [8] If such footpaths are in urban environments and are meant for both pedestrians and pedal cyclists, they can be called shared use paths [9] or multi-use paths in general and official usage.

Some shopping streets are for pedestrians only. Some roads have special pedestrian crossings. A bridge solely for pedestrians 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 a road with no footpath. [10]

Indoor pedestrian networks

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. [11] Different mapping tools, such as OpenStreetMap, are extending to indoor spaces. [12]

Pedestrianisation

Pedestrianisation might be considered as 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. [13]

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 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%). [14]

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 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 issues

Safety is an important issue where cars can cross the pedestrian way. Drivers and pedestrians share some responsibility for improving safety of road users. [15] Road traffic crashes are not inevitable; they are both predictable and preventable. [13]

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 a vehicle. [13] 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. [16] There is an increasing focus on pedestrians versus motor vehicles in many countries.[ citation needed ]

Most pedestrian injuries occur while they are crossing a street. [13] Most crashes involving a pedestrian occur at night. [13] Most pedestrian fatalities are killed by 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. [13] Then the head hits the windscreen at the velocity of the striking car. Finally, the victim falls to the ground. [13]

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. [17]

Some special interest groups consider pedestrian fatalities on American roads a carnage. [18] Five states – Arizona, California, Florida, Georgia and Texas – are the site of 46% of all pedestrian deaths in the country. [18] The advent of SUVs is considered a leading cause; [19] speculation of other factors includes population growth, driver distraction with mobile phones, poor street lighting, alcohol and drugs and speeding. [18]

Cities have had mixed results in addressing pedestrian safety with Vision zero plan: Los Angeles fails while NYC has had success. Nonetheless, in the US, some pedestrians have just 40 seconds to cross a street 10 lanes wide. [18]

Pedestrian fatalities are much more common in accident situations in the European Union than in the United States. In the European Union countries, more than 200,000 pedestrians and cyclists are injured annually. [20] Also, each year, more than 270 000 pedestrians lose their lives on the world's roads. [13] At a global level pedestrians constitute 22% of all road deaths, [13] but might be two-thirds in some countries. [13] Pedestrian fatalities, in 2016, were[ needs update ] 2.6 per million population in the Netherlands, 4.3 in Sweden, 4.5 in Wales, 5.3 in New Zealand, 6.0 in Germany; 7.1 in the whole United Kingdom, 7.5 in Australia, 8.4 in France, 8.4 in Spain, 9.4 in Italy, 11.1 in Israel, 13 in Japan, 13.8 in Greece, 18.5 in the United States, 22.9 in Poland, and 36.3 in Romania.

Road design impact on safety

It is well documented that a minor increase in speed might greatly increase the likelihood of a crash, and exacerbate resulting casualties. For this reason, 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. [13]

Traffic lights for pedestrians are also a factor in increasing safety. Animated pedestrian traffic light showing the pan-European sign. Euro-pedestrian traffic light.gif

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. [13] For instance, an assessment of roads in countries from many continents shows that 84% of roads are without pedestrian footpaths, while maximum limited speed is greater than 40 km/h. [13]

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. [13]

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.) [13]

A similar set of policies to discourage 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. [26]

Seasonality

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. [27]

Health benefits and environment

Regular walking 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.

Unicode

In Unicode, the hexadecimal code for "pedestrian" is 1F6B6. In XML and HTML, the string 🚶 produces 🚶. [28]

Urban planners and traffic engineers have many strategies for traffic calming, including narrowed roads and speed humps. Such measures are common in Australia and Europe, but less so in North America. Traffic calming is a calque of the German word Verkehrsberuhigung – the term's first published use in English was in 1985 by Carmen Hass-Klau.

Due to its prevalence, cycling is sometimes considered separately from the other forms of active mobility.

<span class="mw-page-title-main">Shared-use path</span> Pathway for pedestrians and cyclists

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.

<span class="mw-page-title-main">Safety of cycling infrastructure</span> Overview of bicycle safety concerns

There is debate over the safety implications of cycling infrastructure. Recent studies generally affirm that segregated cycle tracks have a better safety record between intersections than cycling on major roads in traffic. Furthermore, cycling infrastructure tends to lead to more people cycling. A higher modal share of people cycling is correlated with lower incidences of cyclist fatalities, leading to a "safety in numbers" effect though some contributors caution against this hypothesis. On the contrary, older studies tended to come to negative conclusions about mid-block cycle track safety.

A personal transporter is any of a class of compact, mostly recent, motorised micromobility vehicle for transporting an individual at speeds that do not normally exceed 25 km/h (16 mph). They include electric skateboards, kick scooters, self-balancing unicycles and Segways, as well as gasoline-fueled motorised scooters or skateboards, typically using two-stroke engines of less than 49 cc (3.0 cu in) displacement. Many newer versions use recent advances in vehicle battery and motor-control technologies. They are growing in popularity, and legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation.

<span class="mw-page-title-main">Stroad</span> Type of thoroughfare

A stroad is a type of thoroughfare that is a mix between a street and a road. Common in the United States and Canada, stroads are wide arterials that often provide access to strip malls, drive-throughs, and other automobile-oriented businesses. Urban planners have criticized stroads for their safety issues and poor efficiency. While streets provide access to shops and residences at safe traffic speeds, and roads can efficiently move traffic at high speed and volume, stroads pose dangers to drivers and pedestrians and are also prone to congestion.
