There are various materials to choose for this method including hot pour bituminous liquid, silicone and preformed compression seals. Careful design and construction of roads can increase road traffic safety and reduce the harm deaths, injuries, and property damage on the highway system from traffic collisions.
On neighborhood roads traffic calming , safety barriers , pedestrian crossings and cycle lanes can help protect pedestrians, cyclists, and drivers. Lane markers in some countries and states are marked with Cat's eyes or Botts dots, bright reflectors that do not fade like paint. Botts dots are not used where it is icy in the winter, because frost and snowplows can break the glue that holds them to the road, although they can be embedded in short, shallow trenches carved in the roadway, as is done in the mountainous regions of California.
For major roads risk can be reduced by providing limited access from properties and local roads, grade separated junctions and median dividers between opposite-direction traffic to reduce likelihood of head-on collisions. The placement of energy attenuation devices e.
Some road fixtures such as road signs and fire hydrants are designed to collapse on impact. Light poles are designed to break at the base rather than violently stop a car that hits them. Highway authorities may also remove larger trees from the immediate vicinity of the road.
During heavy rains, if the elevation of the road surface isn't higher than the surrounding landscape, it may result in flooding. Speed limits can improve road traffic safety and reduce the number of road traffic casualties from traffic collisions. In their World report on road traffic injury prevention report, the World Health Organization WHO identify speed control as one of various interventions likely to contribute to a reduction in road casualties.
Road conditions are the collection of factors describing the ease of driving on a particular stretch of road, or on the roads of a particular locality, including the quality of the pavement surface , potholes , road markings, and weather. It has been reported that "[p]roblems of transportation participants and road conditions are the main factors that lead to road traffic accidents". For example, for autonomous vehicles such as self-driving cars , significant road conditions can include "shadowing and lighting changes, road surface texture changes, and road markings consisting of circular reflectors, dashed lines, and solid lines".
Various government agencies and private entities, including local news services, track and report on road conditions to the public, so that drivers going through a particular area can be aware of hazards that may exist in that area. News agencies, in turn, rely on tips from area residents with respect to certain aspects of road conditions in their coverage area. Water management systems can be used to reduce the effect of pollutants from roads.
Road runoff is a major source of nickel , copper, zinc , cadmium , lead and polycyclic aromatic hydrocarbons PAHs , which are created as combustion byproducts of gasoline and other fossil fuels. De-icing chemicals and sand can run off into roadsides, contaminate groundwater and pollute surface waters ;  and road salts can be toxic to sensitive plants and animals.
Roads are a chief source of noise pollution. In the early s it was recognized [ by whom? Regulations can restrict the use of engine braking. Motor vehicle emissions contribute air pollution. Concentrations of air pollutants and adverse respiratory health effects are greater near the road than at some distance away from the road. Traffic flows on the right or on the left side of the road depending on the country. Roads are generally built and maintained by the public sector using taxation although implementation may be through private contractors. Public-private partnerships are a way for communities to address the rising cost by injecting private funds into the infrastructure.
There are four main ones: . Society depends heavily on efficient roads. According to the New York State Thruway Authority,  some sample per-mile costs to construct multi-lane roads in several US northeastern states were:. See List of countries by road network size. Eurasia, Africa, North America, South America, and Australia each have an extensive road network that connects most cities. Eurasia and Africa are connected by roads on the Sinai Peninsula.
Antarctica has very few roads and no continent-bridging network, though there are a few ice roads between bases, such as the South Pole Traverse. Bahrain is the only island country to be connected to a continental network by road the King Fahd Causeway to Saudi Arabia. Even well-connected road networks are controlled by many different legal jurisdictions, and laws such as which side of the road to drive on vary accordingly. Many populated domestic islands are connected to the mainland by bridges. Even on mainlands, some settlements have no roads connecting with the primary continental network, due to natural obstacles like mountains or wetlands, remoteness, or general expense.
Unpaved roads or lack of roads are more common in developing countries , and these can become impassible in wet conditions. Most disconnected settlements have local road networks connecting ports, buildings, and other points of interest. For long-distance trips, passengers usually travel by air and rent a car upon arrival. If facilities are available, vehicles and cargo can also be shipped to many disconnected settlements by boat, or air transport at much greater expense.
The island of Great Britain is connected to the European road network by Eurotunnel Shuttle — an example of a car shuttle train which is a service used in other parts of Europe to travel under mountains and over wetlands. In polar areas, disconnected settlements are often more easily reached by snowmobile or dogsled in cold weather, which can produce sea ice that blocks ports, and bad weather that prevents flying.
For example, resupply aircraft are only flown to Amundsen—Scott South Pole Station October to February, and many residents of coastal Alaska have bulk cargo shipped in only during the warmer months. Permanent darkness during the winter can also make long-distance travel more dangerous in polar areas.
Continental road networks do reach into these areas, such as the Dalton Highway to the North Slope of Alaska, the R21 highway to Murmansk in Russia, and many roads in Scandinavia though due to fjords water transport is sometimes faster. Large areas of Alaska, Canada, Greenland, and Siberia are sparsely connected. For example, all 25 communities of Nunavut are disconnected from each other and the main North American road network. Road transport of people and cargo by may also be obstructed by border controls and travel restrictions.
For example, travel from other parts of Asia to South Korea would require passage through the hostile country of North Korea. Moving between most countries in Africa and Eurasia would require passing through Egypt and Israel, which is a politically sensitive area. Some places are intentionally car-free , and roads if present might be used by bicycles or pedestrians. Additional intercontinental and transoceanic fixed links have been proposed, including a Bering Strait crossing that would connect Eurasia-Africa and North America, a Malacca Strait Bridge to the largest island of Indonesia from Asia, and a Strait of Gibraltar crossing to connect Europe and Africa directly.

Archived from the original on Most of the provisions apply on all roads throughout Great Britain, although there are some exceptions. The land over which a public right of way exists is known as a highway; and although most highways have been made up into roads, and most easements of way exist over footpaths, the presence or absence of a made road has nothing to do with the distinction.
Historically, a highway comprehended any path in which members of the public had the right to pass and re-pass without let or hindrance. The term embraced footpaths, bridleways, driftways and so forth. The advent of the motor vehicle and its peculiar requirements has seen increasing distinctions between paths over which walkers and riders have a right of way and those ways that are predominantly used by motor vehicles. The former may be usefully termed "rights of way" and are the subject of a separate entry in this web and the latter may be termed "highways.
