How Do You Select The Best Driveway or Driveway Pavement?

A driveway (also called drive in UK English) Driveway Pavement in Fourways is a type of private road for local access to one or a small group of structures, and is owned and maintained by an individual or group.
Driveways rarely have traffic lights, but some that bear heavy traffic, especially those leading to commercial businesses and parks, do.
Driveways may be decorative in ways that public roads cannot, because of their lighter traffic and the willingness of owners to invest in their construction. Driveways are not resurfaced, snow blown or otherwise maintained by governments. They are generally designed to conform to the architecture of connected houses or other buildings.
Some of the materials that can be used for driveways include concrete, decorative brick, cobblestone, block paving, asphalt, gravel, decomposed granite, and surrounded with grass or other ground-cover plants.
Driveways are commonly used as paths to private garages, carports, or houses. On large estates, a driveway may be the road that leads to the house from the public road, possibly with a gate in between. Some driveways divide to serve different homeowners. A driveway may also refer to a small apron of pavement in front of a garage with a curb cut in the sidewalk, sometimes too short to accommodate a car.
Often, either by choice or to conform with local regulations, cars are parked in driveways in order to leave streets clear for traffic. Moreover, some jurisdictions prohibit parking or leaving standing any motor vehicle upon any residential lawn area (defined as the property from the front of a residential house, condominium, or cooperative to the street line other than a driveway, walkway, concrete or blacktopped surface parking space). Other examples include the city of Berkeley, California that forbids “any person to park or leave standing, or cause to be parked or left standing any vehicle upon any public street in the City for seventy-two or more consecutive hours.” Other areas may prohibit leaving vehicles on residential streets during certain times (for instance, to accommodate regular street cleaning), necessitating the use of driveways.
Residential driveways are also used for such things as garage sales, automobile washing and repair, and recreation, notably (in North America) for basketball practice.
Another form of driveway is a ‘Run-Up’, or short piece of land used usually at the front of the property to park a vehicle on.

A boulevard (French, from Dutch: Bolwerk – bulwark, meaning bastion), often abbreviated Blvd, is a type of large road, usually running through a city.
In modern American usage it often means a wide, multi-lane arterial thoroughfare, often divided with a median down the centre, and perhaps with roadways along each side designed as slow travel and parking lanes and for bicycle and pedestrian usage, often with an above-average quality of landscaping and scenery.
Phnom Penh has numerous boulevards scattered throughout the city. Norodom Boulevard, Sisowath Boulevard, Monivong Boulevard, and Sothearos Boulevard are the most famous.Marine Drive, Mumbai View of Rajpath from Raisina Hill with India Gate at its terminal Keshavarz Boulevard of Tehran, Iran in mid 1970s
In Iran, "Boulevard" is generally defined as a wide road surrounded by trees in sides and divided by a green space line including grass, trees or buxuses in the middle. There are many boulevards in Iran. One of the most famous one is Keshavarz Boulevard in Tehran which is usually referred to as "The Boulevard". Isfahan has also a historical boulevard which is called Chaharbagh Boulevard.
Tel Aviv, was originally designed along the guidelines set out by architect Sir Patrick Geddes. Geddes designed a green or garden ring of boulevards surrounding the central city, which still exists today and continues to characterize Tel Aviv. One of the most famous and busy streets in the city is Rothschild Boulevard.Roxas Boulevard in Manila, Philippines.
Roxas Boulevard is a major boulevard in Metro Manila, Philippines. The boulevard, which runs along the shores of Manila Bay, is popular for its view of Manila's famous sunsets and stretch of coconut trees. The boulevard is an eight-lane major arterial road designated as Radial Road 1 that connects the center of Manila with Pasay and Parañaque.
Other boulevards in Metro Manila include the Shaw Boulevard, España Boulevard, Pedro Tuazon Boulevard and Quezon Boulevard. Not all boulevards in the Philippines have ornamentation, or slow lanes, like the Aurora Boulevard and E. Rodriguez Sr. Boulevard, which have no ornamentation at all.
Osmeña Boulevard is a boulevard in Cebu City, the Philippines' second city. It is Cebu's most important street and is its primary ceremonial avenue, the conventional route of the city's civic and cultural parades. Measuring six to ten lanes wide with 3-5 meter-wide sidewalks on both sides and a landscaped central median, the boulevard is lined with narra trees. Midway is the park and roundabout of Fuente Osmeña.See also: Vienna Ring Road
The Ring Road (German: Ringstraße) is a circular ring road surrounding the Innere Stadt district of Vienna, Austria and is one of its main sights. Constructed in the mid-19th century after the dismantling of the city fortification walls, its architecture is typical of the eclectic, historicist style called Ringstraßenstil (Ring Road Style) of the 1860s to 1890s.
Known for its unique architectural beauty and history, it has also been called the "Lord of the ring roads", and is inscribed by UNESCO as part of Vienna's World Heritage Site.
The Ringstraße is 5.2 kilometers (3.2 miles) long and has several sections. It surrounds the central area of Vienna on all sides, except for the northeast, where its place is taken by the Franz-Josephs-Kai, the street going along the Donaukanal (a branch of the Danube). Starting from the Ringturm at the northern end of the Franz-Josephs-Kai, the sections are:See also: Boulevards of Paris
Baron Haussmann made such roads well known in his re-shaping of Second Empire Paris between 1853 and 1870. The French word boulevard originally referred to the flat summit of a rampart (the etymology of the word distantly parallels that of bulwark which is a Dutch loanword [bolwerk]). Several Parisian boulevards replaced old city walls; more generally, boulevards encircle a city center, in contrast to avenues that radiate from the center.
Boulevard is sometimes used to describe an elegantly wide road, such as those in Paris, approaching the Champs-Élysées. Famous French boulevards: Avenue Montaigne, Montmartre, Invalides, Boulevard Haussmann. Frequenters of boulevards were sometimes called boulevardiersUnter den Linden, Berlin, Germany.
The historically most famous boulevard in Berlin and arguably in all of Germany is Unter den Linden: location of the Berlin State Opera, Berlin Cathedral, the former royal palace, Humboldt University, the Neue Wache state memorial, the Germany Historical Museum housed in the old arsenal and Brandenburg Gate being the boulevard's focal point. Most famed for its classy shopping facilities is Berlin's Kurfürstendamm.
In the 1920s it was considered one of the most cosmopolitan places in Europe, being not only an elegant residential area but also a major centre of nightlife and leisure. Ku'damm retained this air throughout the Cold War becoming the hub of free West-Berlin. Still today it is the city's most frequented shopping district.
A notable boulevard in Berlin's East is Karl-Marx-Allee, which was built primarily in the 1950s in Stalinist Classicism architecture with decorative buildings. One section of the boulevard is more decorative while the other is more modern. In the center of the boulevard is the Strausberger Platz, which has buildings in wedding-cake style. The boulevard is divided into various blocks. Between 1949 and 1989, it was the main center of East Berlin. The Königsallee in Düsseldorf is known for its many famous fashion stores and showrooms.
Munich is well known for its four royal avenues constructed by the Bavarian monarchs of the 19th century, which can also be classified as boulevards: Brienner Straße, Leopoldstrasse, Maximilianstraße, and Prinzregentenstraße.Combino Supra at the Grand Boulevard, Budapest, Hungary
The Hungarian capital Budapest is also known for its well planned street system with wide avenues and boulevards, running through the city. There are three main boulevards, named Little Boulevard, Grand Boulevard and Hungária Boulevard. Little Boulevard was built on the demolished medieval city walls of Pest in the late 19th century. Grand Boulevard, the most prominent, was built for the 1000th anniversary of the Hungarian conquest in 1896. It has a uniform facade, and the busiest tram line in Europe.
Hungária Boulevard was built from 1980 to 2000 and it is the widest (70 meters, like Champs-Élysées) and longest (13 kilometers) boulevard in Budapest with six to ten traffic lanes and a rapid tram line. Although the construction of the boulevard was finished in 2000, the facade is still incomplete, as there are many empty parcels due to demolition of old apartments and factories.
As in the UK, Ireland also has a lack of boulevards, but O'Connell Street in Dublin is one of Europe's widest streets and is very like a Victorian boulevard. In recent housing developments in Dublin, the boulevard is becoming more and more common in addresses (e.g. Tyrellstown Blvd, Park Blvd, Bayside Blvd), and a boulevard was opened in Gorey, County Wexford in early 2015.Boulevard in Florence, Italy
Florence's historic centre, for example, is surrounded by the Viali di Circonvallazione, a series of 6-lane wide streets; the boulevards follow the outline of the ancient walls of Florence, that were demolished since 1865 to make Florence, then the capital of Italy (for 5 years, 1865–1870), a modern and big city like the other European capitals. The Viali were inspired by the similar Parisian boulevards.Oder in Szczecin
Boulevards are representative places in cities situated near big rivers and usually parts of their centres, for example in Cracow, Warsaw, Toruń, Bydgoszcz, Gdańsk, Gorzów Wielkopolski, Wrocław and Świnoujście.
One of the most famous boulevards in Poland is the street named Wały Chrobrego (former German name: Hakenterrasse) in Szczecin, where the final events of The Tall Ships' Races took place in 2007 and 2013. This is a street complex, about 100 years old, at the river bank of Oder with some connections to the harbour in Szczecin and the Baltic Sea. There are many tourist attractions e.g. National Museum in Szczecin, The Contemporary Theater (Teatr Współczesny), Statue of Hercules fighting the Centaur and the waterfront for ships, including harbour cruise ships and hydrofoil to Świnoujście. In the area there are more historic buildings situated, for instance The Ducal Castle.
Some tourist towns and villages are known among others for their boulevards and esplanades. There are many localities situated by the sea, for example Sopot, Gdynia, Kołobrzeg, Misdroy and Świnoujście, or other types of big water areas as Trzebież lying on the Szczecin Lagoon. Feliks Nowowiejski Seaside Boulevard in Gdynia was the first stage of the Tour de Pologne in 2003. Boulevards are also representative places in Gryfino (dictrict town in Poland) and German village Mescherin localized by both sides of the valley of Oder river protected with Lower Odra Valley Landscape Park.
There are also many boulevards by lakes and small rivers, mainly in harbours areas, as in Giżycko, and in urban parks, for example in Łobez, Piotrków Trybunalski, Poznań and the oldest Polish urban park in Kalisz founded in 1798. Boulevards and paths in Łazienki Park in Warsaw surround Palace on the Water. The medieval port crane, called Żuraw, over Motława river, the junction of two boulevards - Długie Pobrzeże and Rybackie Pobrzeże - is the symbol of the medieval harbour of Gdańsk. The Old Town Promenade (Promenada Staromiejska) in Wrocław was built on the former on the former defensive fortifications along the City Moat and a small section along the Oder river. The boulevard in Kasprowicz Park in Szczecin leads along Rusałka Lake from the City Hall area to The Summer Theater (Teatr Letni) and then to Różanka Rose Garden and the forest of Puszcza Wkrzańska. The scenic above ground promenade in Augustów enables the observation of the Augustów Canal and national roads 8 and 16.Clean Ponds in the wide median green of Chistoprudny Boulevard, Moscow, Russia
The dictionary defines boulevard as a wide green strip in the middle of a city street or on the embankment. Historical Boulevard Ring in Moscow emerged on the site of the former White City walls (demolished in the 1760s and 1770s) before the Fire of 1812, starting with Tverskoy Boulevard in 1796. The whole ring was replanted and rebuilt after the fire, in the 1820s; together with the embankments of Moskva River the boulevards form the second centremost city ring.
Green boulevards of that period were terminated with corner hotel and shop buildings, most of them eventually demolished to make way for street traffic. Garden Ring, developed in the middle of the 19th century, had traditional median boulevards in its western part and side gardens in the east (streets with side strips of green, even those separating main traffic and frontage roads, are not usually considered boulevards).
Street names of Saint Petersburg evolved differently: median greens of major avenues were called boulevards, but the avenues themselves typically were and still are called prospekts (i.e. Bolshoy Prospekt of Vasilievsky Island).
Owing to city planning and physical geography, the UK has only a few boulevards. Glasgow's Mosspark Boulevard, a former segregated tram and car wide road along Bellahouston Park, and Great Western Road, colloqially known as 'The Boulevard' north of the River, is a good example, a mostly dual carriageway road running to the outer suburbs passing through the fashionable West End district, with many shops and bars dotted along the route.
After the Great Fire of London, London was supposed to be formed of straight boulevards, squares and plazas which are seen in mainland Europe, but due to land ownership issues these plans never came to fruition. Boulevards in London are rare but examples, such as Blackfriars Road, do exist. Milton Keynes, Buckinghamshire, is one of only a handful of examples where boulevards are a key feature. This is due to Milton Keynes being built as a modern new town in the 1960s.
Nottingham (and to a lesser extent, Leicester) also have extensive networks of boulevards, although some lower-capacity highways are named boulevards even when they are streets; for example Gilbert Boulevard, Arnold (Asquith Way/Boulevard, West Knighton).
Furthermore, the north-west town of Warrington in Cheshire has a large number of boulevards, some more recent than others. Lining the Gemini Retail Park in Warrington is Europa Boulevard with the traditional tree lined pavements and two-lane traffic. Also, on the recent housing development, Chapelford - built on the old Burtonwood Airbase site, are a number of boulevards such as Boston and Santa Rosa Boulevard, built in reference to the American history associated from World War II on the site.Barbaros Boulevard in Istanbul, Turkey
Barbaros Boulevard is opened in 1958 due to new city planning in Istanbul. Ankara also has a lot of boulevards.View of Mexico City's Paseo de la Reforma from Castillo de Chapultepec.
In the Dominican Republic, more specifically in Greater Santo Domingo there is the Winston Churchill and 27 de Febrero Boulevard in Downtown Santo Domingo and Las Americas Boulevard in Santo Domingo Este. These boulevards are known for their wide median with plazas and trees on it.
Paseo de la Reforma (English: "Reform Promenade") is a 12 kilometer long boulevard in Mexico City, Mexico that runs in a straight line, cutting diagonally across the city. It runs from Chapultepec Park, then passes alongside the Torre Mayor (currently Latin America's tallest building), continues through the fashionable Zona Rosa and then to the Zócalo by Juárez Avenue and Francisco I. Madero Street. One of the most famous monuments of the Paseo is El Ángel de la Independencia – a tall column with a gilded statue of a Winged Victory on its top and marble statues at its base depicting the heroes of the Mexican War of Independence.
The Paseo de la Reforma was designed in the 1860s during the Second Mexican Empire by the Austrian military officer and engineer Ferdinand von Rosenzweig on the orders of Maximilian I of Mexico. He wanted to connect his imperial residence, Chapultepec Castle, to the Palacio Nacional in the city's center. When it was inaugurated, it was named the Paseo de la Emperatriz (The Empress's Promenade), after his consort, Empress Carlota of Mexico. The name now commemorates the liberal reforms of 19th-century president Benito Juárez.Queens Boulevard in New York City Road verge (or Boulevard) in Oak Park, Illinois Roosevelt Boulevard in Philadelphia, Pennsylvania
In many places in the United States of America and Canada, municipalities and developers have adapted the term to refer to arterial roads, not necessarily boulevards in the traditional sense. In California, many so-called "boulevards" extend into the mountains as narrow, winding road segments only two lanes in width. However, boulevards can be any divided highway with at-grade intersections to local streets. They are commonly abbreviated Blvd. Some celebrated examples in California include:
In Chicago, the boulevard system is a network of wide, planted-median boulevards that winds through the south, west, and north sides of the city and includes a ring of parks. Most of the boulevards and parks are 3–6 miles from The Loop. Trucks are not allowed on boulevards in Chicago. Seattle also features a network of boulevards that connect most of the city's public parks to each other, a design recommended by the Olmsted Brothers.
In Philadelphia, the boulevard system includes the length of the Benjamin Franklin Parkway known as the Museum District. It also includes the arterial roadway of the Roosevelt Boulevard and the Southern Boulevard Parkway built as a connecting median of two urban parks, but now also serves as the west roadway entrance of the world class centralized Philadelphia Sports Complex and gatehouse entrance of the Philadelphia Navy Yard in South Philadelphia.
Sometimes, the word "boulevard" is used as a standalone name, as is the case in Atlanta, and Roosevelt Boulevard in the Northeast section of Philadelphia is sometimes referred to, chiefly by locals, simply as "The Boulevard." In Pittsburgh, "The Boulevard of the Allies" runs through and connects major areas of the city.
Kansas City, Missouri and St. Louis, Missouri are famous for having more boulevards and avenues in the world than any city (if the term is used lightly). In Charlotte, North Carolina, Independence Boulevard connects Uptown to the southeastern section of the city, although the westernmost segment is actually a freeway.
New York City has a lot of boulevards, many of which are not designated as such (like Ocean Parkway or Broadway). In the borough of Queens, many important thoroughfares are designated as Boulevards.
Nineteenth century parkways, such as Brooklyn's Ocean Parkway, were often built in the form of boulevards and are informally referred to as such. In some cities, however, the term "boulevard" does not specify a larger, wider, or more important road. "Boulevard" may simply be used as one of many words describing roads in communities containing multiple iterations of the same street name (such as in the Ranchlands district of Calgary, where Ranchlands Boulevard exists side-by-side with Ranchlands Road, Ranchlands Court, Ranchlands Mews, etc.) Nowadays boulevards can be found most anywhere and their original structured meaning has lost almost all meaning.
Lake Shore Boulevard, a six-lane thoroughfare runs along the lakefront in Toronto from Woodbine Avenue in the east to the city limits in the west. The section between Jameson Avenue and the Humber River (the original section), as an example of urban planning, was laid out to provide a pleasant drive with a view of Humber Bay on Lake Ontario and easy access to the park lands by automobile. It was later expanded for commuting.
A famous American example is Las Vegas Boulevard in Las Vegas, Nevada.Norodom Boulevard
Melbourne has at least four roads named "the Boulevard." These are, generally, long roads with many curves which wind alongside the Yarra River. In addition, the spelling of boulevard with an extra 'e' is common, for example the Southlands Boulevarde shopping centre in southern Perth. Australia post officially abbreviates boulevard as "BVD".
Several Melbourne thoroughfares not named as a boulevard do in fact follow the boulevard configuration of multiple lanes and landscaping. These include St Kilda Road, Royal Parade, Victoria Parade, Flemington Road, and the outer section of Mount Alexander Road.
Boulevards in Sydney include:
Additionally, single-suburb boulevards are situated in Brighton-le-Sands, Cammeray, Cheltenham, Epping, Lidcombe, Lilyfield, Malabar, Newport, Sans Souci, Strathfield and Yagoona.
Construction began on the Orewa Boulevard in March 2009, the works are expected to be complete by February 2010. This boulevard will be approximately 400 m long with Pohutukawa and palm lined footpaths, a wide cycleway will be constructed on the beach side of the road and carparks on the business side. The Orewa Boulevard is a project commissioned by the Rodney District Council with the vision of connecting the CBD to Orewa Beach.
Central Christchurch is surrounded and connected by a series of large boulevards (usually called "avenues" in New Zealand). These include four which surround the central city, Bealey Avenue, Fitzgerald Avenue, Deans Avenue, and Moorhouse Avenue, and also Riccarton Avenue, which traverses the large central city park, Hagley Park. The centre of the city is often described locally as being "within the Four Avenues".
Avenida 9 de Julio in the heart of Buenos Aires, which is the capital city of Argentina, is as wide as 7 lanes in each direction, with 4 further lanes flanking the main boulevard in parallel roads on either side.View of Bogota’s La Soledad Park Way Boulevard
In Bogotá, ‘’’La Soledad Park Way Boulevard’’’ is an 1 kilometer important boulevard, in the Locality of Teusaquillo located in Bogotá’s City Center and it crosses from the street 35 to street 45.
In the boulevard you can see several monuments and restaurants including Crepes & Waffles, Kokoriko, Subway, The Cheesecake Factory, and the historical hotel ‘’Hotel Park Way Boulevard’’
In Montevideo, Artigas Boulevard is an important avenue (40 metres (130 ft) wide) that encloses the central area.
Driveway Pavement in NorthgateRaised sidewalks beside a 2000-year-old paved road, Pompeii, Italy
A sidewalk (American English) or pavement (British English), also known as a footpath or footway, is a path along the side of a road. A sidewalk may accommodate moderate changes in grade (height) and is normally separated from the vehicular section by a curb. There may also be a median strip or road verge (a strip of vegetation, grass or bushes or trees or a combination of these) either between the sidewalk and the roadway or between the sidewalk and the boundary.
In some places, the same term may also be used for a paved path, trail or footpath that is not next to a road, for example, a path through a park.
The term "sidewalk" is usually preferred in most of North America, along with many other countries worldwide that are not members of the Commonwealth of Nations. The term "pavement" is more common in the United Kingdom, as well as parts of the Mid-Atlantic United States such as Philadelphia and New Jersey. Many Commonwealth countries use the term "footpath". The professional, civil engineering and legal term for this in North America is "sidewalk" while in the United Kingdom it is "footway".
In the United States, the term sidewalk is used for the pedestrian path beside a road. "Shared use paths" or "multi-use paths" are available for use by both pedestrians and bicyclists. "Walkway" is a more comprehensive term that includes stairs, ramps, passageways, and related structures that facilitate the use of a path as well as the sidewalk.
In the UK, the term "footpath" is mostly used for paths that do not abut a roadway. The term "shared-use path" is used where cyclists are also able to use the same section of path as pedestrians.East India House, Leadenhall Street, London, 1766. The sidewalk is separated from the main street by six bollards in front of the building.
There is evidence that sidewalks were built in ancient times. It was claimed that the Greek city of Corinth was paved by the 4th-century, and the Romans were particularly prolific sidewalk builders – they called them semitas.
However, by the Middle Ages, narrow roads had reverted to being simultaneously used by pedestrians and wagons without any formal separation between the two categories. Early attempts at ensuring the adequate maintenance of foot-ways or sidewalks were often made, such as the 1623 Act for Colchester, although they were generally not very effective.
Following the Great Fire of London in 1666, attempts were slowly made to bring some order to the sprawling city. In 1671, 'Certain Orders, Rules and Directions Touching the Paving and Cleansing The Streets, Lanes and Common Passages within the City of London' were formulated, calling for all streets to be adequately paved for pedestrians with cobblestones. Purbeck stone was widely used as a durable paving material. Bollards were also installed to protect pedestrians from the traffic in the middle of the road.
A series of Paving Acts from the House of Commons during the 18th century, especially the 1766 Paving & Lighting Act, authorized the City of London Corporation to create foot-ways throughout all the streets of London, to pave them with Purbeck stone (the thoroughfare in the middle was generally cobblestone) and to raise them above the street level with curbs forming the separation. The Corporation was also made responsible for the regular upkeep of the roads, including their cleaning and repair, for which they charged a tax from 1766. By the late 19th-century large and spacious sidewalks were routinely constructed in European capitals, and were associated with urban sophistication.
In the United States, adjoining property owners must in most situations finance all or part of the cost of sidewalk construction. In a legal case in 1917 involving E. L. Stewart, a former member of the Louisiana House of Representatives and a lawyer in Minden in Webster Parish, the Louisiana Supreme Court ruled that owners must pay whether they wish for the sidewalk to be constructed or not.Pedestrians walking on the pavement (sidewalk) in London.
Sidewalks play an important role in transportation, as they provide a safe path for people to walk along that is separated from the motorized traffic. They aid road safety by minimizing interaction between pedestrians and motorized traffic. Sidewalks are normally in pairs, one on each side of the road, with the center section of the road for motorized vehicles.
In rural roads, sidewalks may not be present as the amount of traffic (pedestrian or motorized) may not be enough to justify separating the two. In suburban and urban areas, sidewalks are more common. In town and city centers (known as downtown in North America) the amount of pedestrian traffic can exceed motorized traffic, and in this case the sidewalks can occupy more than half of the width of the road, or the whole road can be reserved for pedestrians, see Pedestrian zone.
Sidewalks may have a small effect on reducing vehicle miles traveled and carbon dioxide emissions. A study of sidewalk and transit investments in Seattle neighborhoods found vehicle travel reductions of 6 to 8% and CO2 emission reductions of 1.3 to 2.2% Sidewalk with bike path See also: Road traffic safety
Research commissioned for the Florida Department of Transportation, published in 2005, found that, in Florida, the Crash Reduction Factor (used to estimate the expected reduction of crashes during a given period) resulting from the installation of sidewalks averaged 74%. Research at the University of North Carolina for the U.S. Department of Transportation found that the presence or absence of a sidewalk and the speed limit are significant factors in the likelihood of a vehicle/pedestrian crash. Sidewalk presence had a risk ratio of 0.118, which means that the likelihood of a crash on a road with a paved sidewalk was 88.2 percent lower than one without a sidewalk. “This should not be interpreted to mean that installing sidewalks would necessarily reduce the likelihood of pedestrian/motor vehicle crashes by 88.2 percent in all situations. However, the presence of a sidewalk clearly has a strong beneficial effect of reducing the risk of a ‘walking along roadway’ pedestrian/motor vehicle crash.” The study does not count crashes that happen when walking across a roadway. The speed limit risk ratio was 1.116, which means that a 16.1-km/h (10-mi/h) increase in the limit yields a factor of (1.116)10 or 3.
The presence or absence of sidewalks was one of three factors that were found to encourage drivers to choose lower, safer speeds.
On the other hand, the implementation of schemes which involve the removal of sidewalks, such as shared space schemes, are reported to deliver a dramatic drop in crashes and congestion too, which indicates that a number of other factors, such as the local speed environment, also play an important role in whether sidewalks are necessarily the best local solution for pedestrian safety.
In cold weather, black ice is a common problem with unsalted sidewalks. The ice forms a thin transparent surface film which is almost impossible to see, and so results in many slips by pedestrians.
Riding bicycles on sidewalks is discouraged since some research shows it to be more dangerous than riding in the street. Some jurisdictions prohibit sidewalk riding except for children. In addition to the risk of cyclist/pedestrian collisions, cyclists face increase risks from collisions with motor vehicles at street crossings and driveways. Riding in the direction opposite to traffic in the adjacent lane is especially risky.
Since residents of neighborhoods with sidewalks are more likely to walk, they tend to have lower rates of cardiovascular disease, obesity, and other health issues related to sedentary lifestyles. Also, children who walk to school have been shown to have better concentration.Native Americans busking at Orchard Road, Singapore
Some sidewalks may be used as social spaces with sidewalk cafes, markets, or busking musicians, as well as for parking for a variety of vehicles including cars, motorbikes and bicycles.
Contemporary sidewalks are most often made of concrete in the United States and Canada, while tarmac, asphalt, brick, stone, slab and (increasingly) rubber are more common in Europe. Different materials are more or less friendly environmentally: pumice-based trass, for example, when used as an extender is less energy-intensive than Portland cement concrete or petroleum-based materials such as asphalt or tar-penetration macadam). Multi-use paths alongside roads are sometimes made of materials that are softer than concrete, such as asphalt.
In the 19th century and early 20th century, sidewalks of wood were common in some North American locations. They may still be found at historic beach locations and in conservation areas to protect the land beneath and around, called boardwalks.
Brick sidewalks are found in some urban areas, usually for aesthetic purposes. Brick sidewalk construction usually involves the usage of a mechanical vibrator to lock the bricks in place after they have been laid (and/or to prepare the soil before laying). Although this might also be done by other tools (as regular hammers and heavy rolls), a vibrator is often used to speed up the process.
Stone slabs called flagstones or flags are sometimes used where an attractive appearance is required, as in historic town centers. In other places, pre-cast concrete slabs (called paving slabs or, less correctly, paving stones) are used. These may be colored or textured to resemble stone.Freshly laid concrete sidewalk, with horizontal strain-relief grooves faintly visible
In the United States and Canada, the most common type of sidewalk consists of a poured concrete ribbon, examples of which from as early as the 1860s can be found in good repair in San Francisco, and stamped with the name of the contractor and date of installation. When quantities of Portland cement were first imported to the United States in the 1880s, its principal use was in the construction of sidewalks.
Today, most sidewalk ribbons are constructed with cross-lying strain-relief grooves placed or sawn at regular intervals typically 5 feet (1.5 m) apart. This partitioning, an improvement over the continuous slab, was patented in 1924 by Arthur Wesley Hall and William Alexander McVay, who wished to minimize damage to the concrete from the effects of tectonic and temperature fluctuations, both of which can crack longer segments. The technique is not perfect, as freeze-thaw cycles (in cold-weather regions) and tree root growth can eventually result in damage which requires repair.
In highly variable climates which undergo multiple freeze-thaw cycles, the concrete blocks will be separated by expansion joints to allow for thermal expansion without breakage. The use of expansion joints in sidewalks may not be necessary, as the concrete will shrink while setting.
In the United Kingdom, Australia and France suburban sidewalks are most commonly constructed of tarmac. In urban or inner-city areas sidewalks are most commonly constructed of slabs, stone, or brick depending upon the surrounding street architecture and furniture.
Bleeding or flushing is shiny, black surface film of asphalt on the road surface caused by upward movement of asphalt in the pavement surface. Common causes of bleeding are too much asphalt in asphalt concrete, hot weather, low space air void content and quality of asphalt.
Bleeding is a safety concern since it results in a very smooth surface, without the texture required to prevent hydroplaning.
