An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, for example the fingerposts in the United Kingdom and their wooden counterparts in Saxony.
A milestone is a numbered marker placed on a route such as a road, railway line, canal or boundary. They can indicate the distance to towns, cities, and other places or landmarks like mileage signs; or they can give their position on the route relative to some datum location. On roads they are typically located at the side or in a median or central reservation. They are alternatively known as mile markers, mileposts or mile posts. A "kilometric point" is a term used in metricated areas, where distances are commonly measured in kilometres instead of miles. "Distance marker" is a generic unit-agnostic term.
A warning sign is a type of sign which indicates a potential hazard, obstacle, or condition requiring special attention. Some are traffic signs that indicate hazards on roads that may not be readily apparent to a driver.
The Manual on Uniform Traffic Control Devices for Streets and Highways 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. In the United States, all traffic control devices must legally conform to these standards. The manual is used by state and local agencies as well as private construction firms to ensure that the traffic control devices they use conform to the national standard. While some state agencies have developed their own sets of standards, including their own MUTCDs, these must substantially conform to the federal MUTCD.
Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers, and road signs generally use the imperial system of units, unlike the rest of Europe. Signs in Wales and parts of Scotland are bilingual.
Transport is a sans serif typeface first designed for road signs in the United Kingdom. It was created between 1957 and 1963 by Jock Kinneir and Margaret Calvert as part of their work as designers for the Department of Transport's Anderson and Worboys committees.
A fingerpost is a type of sign post consisting of a post with one or more arms, known as fingers, pointing in the direction of travel to places named on the fingers, often including distance information.
The Convention on Road Signs and Signals, commonly known as the Vienna Convention on Road Signs and Signals, is a multilateral treaty standardize the signing system for road traffic in use internationally.
The Traffic Signs Regulations and General Directions is the law that sets out the design and conditions of use of official traffic signs that can be lawfully placed on or near roads in Great Britain and the Isle of Man. The regulations, originally introduced in 1965, were the result of the review of British road signage carried out by the Worboys Committee.
European traffic signs present relevant differences between countries despite an apparent uniformity and standardisation. Most European countries refer to the 1968 Vienna Convention on Road Signs and Signals. The convention has been adopted by the following countries : Albania, Armenia, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Moldova, Montenegro, Netherlands, North Macedonia, Norway, Poland, Portugal, Romania, Russia, San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, Ukraine and the United Kingdom. The convention has not been adopted by Ireland, Iceland or Malta.
Road signs in Italy conform to the general pattern of those used in most other European countries, with the notable exception that the background of motorway (autostrada) signs is green and those for 'normal' roads is blue. They are regulated by the Codice della Strada and by the Regolamento di Attuazione del Codice della Strada in conformity with the 1968 Vienna Convention on Road Signs and Signals.
Road signs in Thailand are standardized road signs similar to those used in other nations but much of it resembles road signage systems used in South American countries with certain differences, such as using a blue circle instead of a red-bordered white circle to indicate mandatory actions. Until the early 1980s, Thailand closely followed American, European, Australian, and Japanese practices in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. The Department of Railway maintains a standard on the typeface used in the sign, with custom made type for Thai text, unofficially named “Thang Luang”(อักษรทางหลวง) and a small derivation of FHWA Series fonts typeface, which is used on American road signage, for Latin text. In most Bangkok Metropolitan Area's routes, TS Lopburi is still used.
Road signs in India can vary in design, depending on the location. For most part, they tend to closely follow European practices, usually identical with the United Kingdom or the Vienna Convention on Road Signs and Signals, although yellow rectangular signs that do carry such messages like "Be gentle on my curves" and "Danger creeps when safety sleeps" are present nationwide. Road signs in India are metric.
In Japan, road signs are standardized by the "Order on Road Sign, Road Line, and Road Surface Marking (道路標識、区画線及び道路標示に関する命令)" established in 1968 with origins from the Tokyo Metropolitan Police Department's "Order on Standardization of Road Sign" of 1934 and the Home Ministry of Japan's "Order on Road Signs" of 1942. The previous designs have been used since 1986 after several amendments of order.
The Worboys Committee was formed by the British government to review signage on all British roads. In its July 1963 report Traffic signs: report of the committee on traffic signs for all-purpose roads, it found existing road signs to be obsolete for the increasing numbers of motor vehicles and their increasing speeds, and made over a dozen key recommendations. The committee went on to completely revise road signs in Britain, with an emphasis on symbols alone, adopting standard colour and shape practices used in mainland Europe and a new typeface. Its principles were adopted and are still the basis of all road signs in the United Kingdom.
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
Road signs in Malta are regulated by the Road Signs and Road Markings Regulations 1969, amended several times over the years, most recently in 2011, and are standardised by Transport Malta. Maltese road signs are divided into warning signs, regulatory signs, information signs and road markings. The Transport typeface is used on road signs as well as on road signs in the United Kingdom. Maltese road signs, regulated by The Highway Code of Malta, are based on those used in the United Kingdom, since the island nation was a British colony until 1964 when it became independent, with minor exceptions, for example, speeds are measured in kilometres per hour and distances in metres. However, road signs produced in Italy may be found in Malta and are identical to those used in Italy currently or in the past, sometimes "mirrored"; in these cases the "Alfabeto Normale" typeface is used, as in Italy. To date, in the Maltese archipelago there is therefore the coexistence of different signs on the British and, to a lesser extent, Italian model for the same function. It is rarely possible to encounter, again without any official nature, diamond-shaped warning signs similar to those used in Ireland.
Road signs in Russia are governed by the traffic rules approved by the Decree of the Government of the Russian Federation No. 1090 of 23 October 1993 “On the Rules of the Road”, Appendix 1 “Road Signs”. They are regulated by the ГОСТ Р 52289-2019 and ГОСТ Р 52290-2004 standards determining the rules for the use and production of road signs. The vast majority of road signs used in Russia were in the preceding Soviet standard ГОСТ 10807-78, which was introduced in the Soviet Union on January 1, 1980 before its dissolution in 1991 and is no longer valid in Russia since January 1, 2006 after it was replaced by the modern standard ГОСТ Р 52290-2004 for road signs. Road signs generally conform to the Vienna Convention on Road Signs and Signals. Similar road signs are also used in other post-Soviet states.
This article is a summary of traffic signs used in each country.
