The Info List - Street Sign





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
United Kingdom
and their wooden counterparts in Saxony. With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees.

International conventions[edit] Various international conventions have helped to achieve a degree of uniformity in Traffic Signing in various countries[1]. Categories[edit]

Traffic signs can be grouped into several types. For example, Annexe 1 of the Vienna Convention on Road
Road
Signs and Signals (1968), which on 30 June 2004 had 52 signatory countries, defines eight categories of signs:

A. Danger warning signs B. Priority signs C. Prohibitory or restrictive signs D. Mandatory signs E. Special
Special
regulation signs F. Information, facilities, or service signs G. Direction, position, or indication signs H. Additional panels

In the United States, Canada, Ireland, Australia, and New Zealand signs are categorized as follows:

Regulatory signs Warning signs Guide signs

In the United States, the categories, placement, and graphic standards for traffic signs and pavement markings are legally defined in the Federal Highway Administration's Manual on Uniform Traffic Control Devices as the standard. A rather informal distinction among the directional signs is the one between advance directional signs, interchange directional signs, and reassurance signs. Advance directional signs appear at a certain distance from the interchange, giving information for each direction. A number of countries do not give information for the road ahead (so-called "pull-through" signs), and only for the directions left and right. Advance directional signs enable drivers to take precautions for the exit (e.g., switch lanes, double check whether this is the correct exit, slow down). They often do not appear on lesser roads, but are normally posted on expressways and motorways, as drivers would be missing exits without them. While each nation has its own system, the first approach sign for a motorway exit is mostly placed at least 1000 m from the actual interchange. After that sign, one or two additional advance directional signs typically follow before the actual interchange itself. History[edit]

Speed camera sign used in Canada, Cyprus, the Czech Republic, Estonia, Finland, Georgia, Hong Kong, Iceland, Iran, Ireland, Latvia, Malta, Poland, Saudi Arabia, Ukraine, the United Arab Emirates, and the United Kingdom

The earliest road signs were milestones, giving distance or direction; for example, the Romans erected stone columns throughout their empire giving the distance to Rome. In the Middle Ages, multidirectional signs at intersections became common, giving directions to cities and towns. In 1686, the first known Traffic Regulation Act in Europe
Europe
is established by King Peter II of Portugal. This act foresees the placement of priority signs in the narrowest streets of Lisbon, stating which traffic should back up to give way. One of these signs still exists at Salvador street, in the neighborhood of Alfama. The first modern road signs erected on a wide scale were designed for riders of high or "ordinary" bicycles in the late 1870s and early 1880s. These machines were fast, silent and their nature made them difficult to control, moreover their riders travelled considerable distances and often preferred to tour on unfamiliar roads. For such riders, cycling organizations began to erect signs that warned of potential hazards ahead (particularly steep hills), rather than merely giving distance or directions to places, thereby contributing the sign type that defines "modern" traffic signs. The development of automobiles encouraged more complex signage systems using more than just text-based notices. One of the first modern-day road sign systems was devised by the Italian Touring Club in 1895. By 1900, a Congress of the International League of Touring Organizations in Paris
Paris
was considering proposals for standardization of road signage. In 1903 the British government introduced four "national" signs based on shape, but the basic patterns of most traffic signs were set at the 1908 International Road
Road
Congress in Paris.[citation needed] In 1909, nine European governments agreed on the use of four pictorial symbols, indicating "bump", "curve", "intersection", and "grade-level railroad crossing". The intensive work on international road signs that took place between 1926 and 1949 eventually led to the development of the European road sign system. Both Britain and the United States developed their own road signage systems, both of which were adopted or modified by many other nations in their respective spheres of influence. The UK adopted a version of the European road signs in 1964 and, over past decades, North American signage began using some symbols and graphics mixed in with English. Over the years, change was gradual. Pre-industrial signs were stone or wood, but with the development of Darby's method of smelting iron using coke, painted cast iron became favoured in the late 18th and 19th centuries. Cast iron continued to be used until the mid-20th century, but it was gradually displaced by aluminium or other materials and processes, such as vitreous enamelled and/or pressed malleable iron, or (later) steel. Since 1945 most signs have been made from sheet aluminium with adhesive plastic coatings; these are normally retroreflective for nighttime and low-light visibility. Before the development of reflective plastics, reflectivity was provided by glass reflectors set into the lettering and symbols. New generations of traffic signs based on electronic displays can also change their text (or, in some countries, symbols) to provide for "intelligent control" linked to automated traffic sensors or remote manual input. In over 20 countries, real-time Traffic Message Channel incident warnings are conveyed directly to vehicle navigation systems using inaudible signals carried via FM radio, 3G cellular data and satellite broadcasts. Finally, cars can pay tolls and trucks pass safety screening checks using video numberplate scanning, or RFID transponders in windshields linked to antennae over the road, in support of on-board signalling, toll collection, and travel time monitoring. Yet another "medium" for transferring information ordinarily associated with visible signs is RIAS (Remote Infrared Audible Signage), e.g., "talking signs" for print-handicapped (including blind/low-vision/illiterate) people. These are infra-red transmitters serving the same purpose as the usual graphic signs when received by an appropriate device such as a hand-held receiver or one built into a cell phone. Africa[edit]

Road
signs in the Philippines

are classified as:

Regulatory signs Warning signs Guide signs Expressway signs Traffic instruction signs

Regulatory road signs – other than the stop and give way signs – are generally circular, with (for prohibitions) a black symbol on a white background within a red border, or (for mandatory instructions) a white symbol on a blue background. In some cases circular regulatory signs are placed on white rectangular panels together with text supplementing their meanings. Most warning signs display a black symbol on a white background within a red-bordered equilateral triangle. Since 2012, however, a more visibly distinctive design (taken from that used for school signs in the US) has been adopted for pedestrian-related signs: these consist of a fluorescent yellow-green pentagon with black border and symbol. Additional panels may be placed below signs to supplement their meanings. Guide signs are divided into directional signs, service area signs, route markers, and tourist-related signs, with influence from both American and Australian practice. Directional signs use a green background with white letters and arrows. Service area signs use a blue background with white letters, arrows, and symbols. Tourist-related signs use a brown background with white letters, arrows, and symbols. The route marker sign, excluding the AH26 route marker, is based on the Australian National Route marker, but reserved for future use. Signs on expressways mostly take elements from Australian motorway/freeway signs. Exit signs, wrong way signs and start/end of expressway signs are very similar to Australian freeway signage. Traffic instruction signs are textual signs used to supplement warning and regulatory signs.

Since the signing of the 1931 Geneva Convention concerning the Unification of Road
Road
Signals by a number of countries that the standardization of the traffic signs started in Europe. The 1931 Convention rules were developed in the 1949 Geneva Protocol on Road Signs and Signals. In 1968, the European countries signed the Vienna Convention on Road Traffic treaty, with the aim of standardizing traffic regulations in participating countries in order to facilitate international road traffic and to increase road safety. Part of the treaty was the Vienna Convention on Road
Road
Signs and Signals, which defined the traffic signs and signals. As a result, in Western Europe
Europe
the traffic signs are well standardized, although there are still some country-specific exceptions, mostly dating from the pre-1968 era. The principle of the European traffic sign standard is that certain shapes and colours are to be used with consistent meanings:

Triangular signs (black symbols on a white or yellow background) warn of dangers. The Vienna Convention additionally allows an alternative shape for such signs, namely a right-angled diamond – although in Europe
Europe
this shape is regularly used only in the Republic of Ireland. Regulatory signs are round: those indicating a prohibition or limit are black on white (or yellow) with a red border; those giving a mandatory order are white on blue. Informational and various other secondary signs are of rectangular shape. The animals which may be depicted on warning signs include cattle, deer, ducks, elk, frogs, horses, sheep, monkeys (in Gibraltar), and polar bears (on Svalbard). The Convention allows any animal image to be used.

Directional signs ("guide signs" in American parlance) have not been harmonized under the Convention, at least not on ordinary roads. As a result, there are substantial differences in directional signage throughout Europe. Differences apply to the choice of typeface, arrows and, most notably, colours. The convention does, however, specify that the type of directional signage used should, for each country, distinguish limited-access roads ("motorways") from ordinary, all-purpose roads. Directional signage on motorways uses:

white-on-green in, for example, Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Finland, Greece, Italy, the Republic of Macedonia, Romania, Serbia, Slovakia, Slovenia, Sweden, Switzerland, and Turkey white-on-blue in, for example, Austria, Belarus, Belgium, France, Germany, Hungary, Luxembourg, the Netherlands, Norway, Poland, Portugal, the Republic of Ireland, Spain, and the United Kingdom.

Differences are greater for non-motorways:

White-on-blue in Italy, Switzerland, Sweden, the Czech Republic, Greece, Cyprus, Slovakia, Bulgaria, Romania, Latvia, Estonia, Finland, Turkey, and the Netherlands
Netherlands
(in this case the same as on motorways). White-on-green in the United Kingdom, the Republic of Ireland, Poland, France, and Portugal
Portugal
(only on the few primary roads that still have not been transformed in motorways), Black-on-yellow in Bosnia and Herzegovina, Germany, Luxembourg, Norway, Slovenia, Serbia, and Croatia. Red-on-white in Denmark
Denmark
(though white-on-blue on motorway exits and all overhead gantries) Black-on-white in Spain.[5]

The black-on-white signposting of secondary roads distinguishes them from primary roads in Finland, France, Portugal, the Republic of Ireland, Switzerland, and the United Kingdom. In Germany, Italy, Romania, and Sweden
Sweden
black-on-white indicates urban-only roads or urban destinations. The signposting of road numbers also differs greatly, except that European route numbers, if displayed, are always indicated using white characters on a green rectangle. European route numbers are, however, not signed at all in the United Kingdom. The Convention recommends that certain signs – such as "STOP", "ZONE", etc. – be in English; however, use of the local language is also permitted. If a language uses non-Latin characters, a Latin-script transliteration of the names of cities and other important places should also be given. Road

Belgium
are in French, Dutch, or German depending on the region. In the Brussels Capital Region, road signs are in both French and Dutch. Signs in Switzerland
Switzerland
are in French, German, Italian, or Romansh depending on the canton. European countries – with the notable exception of the United Kingdom, where distances and lengths are indicated in miles, yards, feet, and inches, and speed limits are expressed in miles per hour – use the metric system on road signs. For countries driving on the left, the convention stipulates that the traffic signs should be mirror images of those used in countries driving on the right. This practice, however, is not systematically followed in the four European countries driving on the left, Cyprus, Malta, the Republic of Ireland, and the United Kingdom. The convention permits the use of two background colours for danger and prohibition signs: white or yellow. Most countries use white, with a few – such as Finland, Iceland, Poland, and Sweden
Sweden
– opting for yellow as this tends to improve the winter-time visibility of signs in areas where snow is prevalent. In some countries, such as France, white is the normal background colour for such signs, but yellow is used for temporary signage (as, for example, at road works). European traffic signs have been designed with the principles of heraldry in mind;[citation needed] i.e., the sign must be clear and able to be resolved at a glance. Most traffic signs conform to heraldic tincture rules, and use symbols rather than written texts for better semiotic clarity. Croatia[edit] Croatian road signs follow the Vienna convention ( SFR Yugoslavia
SFR Yugoslavia
was the original signatory for Croatia, which is now a contracting party itself). The most common signs are:

and white signs for information. White-on-green signs are used on the highways.

In the first years following Croatia's independence, its traffic signs were the same as in the rest of the former Yugoslavia. In the early 2000s, replacement of the yellow background of warning signs began, and new signs now use a white background. The signage typeface is SNV, as with the other countries of the former Yugoslavia. Iceland[edit] Main article: Road

Road
signs in the Republic of Ireland Until the partition of Ireland
Ireland
in 1922 and the independence of the Irish Free State
Irish Free State
(now the Republic of Ireland), British standards applied across the island. In 1926 road sign standards similar to those used in the UK at the time were adopted.[6] Law requires that the signs be written in both Irish and English. In 1956, road signs in the Republic were changed from the UK standard with the adoption of US-style "diamond" signs for many road hazard warnings (junctions, bends, railway crossings, traffic lights).[7] Some domestic signs were also invented, such as the keep-left sign (a black curved arrow pointing to the upper-left, although some are similar to the European "white arrow on blue disk" signs), while some other signs are not widely adopted outside Ireland, such as the no-entry sign (a black arrow pointing ahead in a white circle with a red slashed circumference). Directional signage is similar to current United Kingdom
United Kingdom
standards. The same colours are used for directional signs in Ireland
Ireland
as in the UK, and the UK Transport and Motorway
Motorway
fonts are used. Unlike Wales
Wales
and Scotland, where Welsh and Gaelic place-names use the upright Transport face, Irish place-names are rendered in an italic face. In January 2005 Ireland
Ireland
adopted metric speed limits. Around 35,000 existing signs were replaced and a further 23,000 new signs erected bearing the speed limit in kilometres per hour. To avoid confusion with the old signs, each speed limit sign now has "km/h" beneath the numerals. Also, since the adoption of signs based on the Warboys Committee standard in 1977, Irish directional signs have used the metric system; however, unlike with the later speed limit changeover, there was no effort made to change the existing signage, and as of 2007[update] many finger posts still remain on rural roads with distances in miles, although the numbers continue to decline as roads are improved. In late 2007 Ireland
Ireland
began an extensive programme of sign and post replacement. Good examples are the M1 (Dublin–Dundalk) and the M50 (Dublin). While being mostly the same as the old signs, it is welcome as a lot of the signs were damaged/stained. About half of the new posts are now two medium posts with crosshatched metal posts in-between instead of one large pole to minimise the damage in case of a crash. Latvia[edit] Road

follow the Vienna Convention. Directional signs (which have not been harmonized under the Convention) always use blue as the background colour. The destinations on the sign are printed in white. If the destination is not a town (but an area within town or some other kind of attraction), that destination will be printed in black on a separate white background within the otherwise blue sign. The Netherlands
Netherlands
always signposts European road numbers where applicable (i.e., on the advance directional signs, the interchange direction signs and on the reassurance signs). Dutch national road numbers are placed on a rectangle, with motorways being signposted in white on a red rectangle (as an Axx) and primary roads in black on a yellow rectangle (as Nxx). When a motorway changes to a primary road, its number remains the same, but the A is replaced by the N. So at a certain point the A2 becomes N2, and when it changes to a motorway again, it becomes A2 again. Signs intended for bike-riders always go on white signs with red or green letters. The Dutch typeface, known as ANWB-Ee, is based on the US typeface. A new font, named ANWB-Uu (also known as Redesign), has been developed in 1997 and appears on many recent Dutch signs. On the motorways however the typeface remains the ANWB-Ee or a similar typeface. The language of the signs is typically Dutch, even though bilingual signs may be used, when the information is relevant for tourists. Norway[edit] Main article: Road

signs in the United Kingdom Traffic signing in the UK conforms broadly to European norms, though a number of signs are unique to Britain and direction signs omit European route numbers. The current sign system, introduced on 1 January 1965, was developed in the late 1950s and early 1960s by the Anderson Committee, which established the motorway signing system, and by the Worboys Committee, which reformed signing for existing all-purpose roads. (For illustrations of most British road signs, see 'Know your traffic signs'[10] on the GOV.UK
GOV.UK
website.) The UK remains the only European Union
European Union
member nation and the only Commonwealth country to use non-metric (Imperial) measurements for distance and speed, although "authorised weight" signs have been in metric tonnes since 1981 and there is currently a dual-unit (metric first) option for height and width restriction signage, intended for use on safety grounds. On motorways kilometre signs are visible at intervals of 500 m indicating the distance from the start of the motorway. (See Driver location sign). Three colour schemes exist for direction signs:

On motorways they are blue with white lettering On primary routes they are green with white lettering and yellow route numbers A non-primary route has white signs with black lettering A fourth colour scheme, black on yellow, is seen on temporary signs, for example marking a diversionary route avoiding a road closure.

Two typefaces are specified for British road signs. Transport "Medium" or Transport "Heavy" are used for all text on fixed permanent signs and most temporary signage, depending on the colour of the sign and associated text colour; dark text on a white background is normally set in "Heavy" so that it stands out better. However route numbers on motorway signs use a taller limited character set typeface called "Motorway". Signs are generally bilingual in all parts of Wales
Wales
(English/Welsh or Welsh/English), and similar signs are beginning to be seen in parts of the Scottish Highlands
Scottish Highlands
(English/Scottish Gaelic). All signs and their associated regulations can be found in the Traffic Signs Regulations and General Directions,[11] as updated by the TSRGD 2008, TSRGD 2011 and TSRGD 2016 and complemented by the various chapters of the "Traffic Signs Manual". Northern America

Every state and province has different markers for its own highways, but use standard ones for all federal highways. Many special highways – such as the Queen Elizabeth Way, Trans- Canada

Highway, and various auto trails in the U.S. – have used unique signs. Counties in the US sometimes use a pentagonal blue sign with yellow letters for numbered county roads, though the use is inconsistent even within states. Units[edit] Distances on traffic signs generally follow the measurement system in use locally: that is to say, the metric system in all countries of the world except Burma, Liberia, the United Kingdom, and the United States – although the metric system is used in the UK for all purposes other than the display of road distances and the defining of speed limits, and in the US the Federal Department of Transportation has developed (very rarely used) metric standards for all signs. Languages[edit]

use bilingual French–English signs in certain localities. Puerto Rico (a US territory) and Mexico use Spanish. Within a few miles of the US–Mexico border, road signs are often in English and Spanish in places like San Diego, Yuma, and El Paso. Indigenous languages, mainly Nahuatl
Nahuatl
as well as some Mayan languages, have been used as well. Typefaces[edit] The typefaces predominantly used on signs in the US and Canada
Canada
are the FHWA alphabet series (Series B through Series F and Series E Modified). Details of letter shape and spacing for these alphabet series are given in "Standard Alphabets for Traffic Control Devices", first published by the Bureau of Public Roads
Bureau of Public Roads
(BPR) in 1945 and subsequently updated by the Federal Highway Administration
Federal Highway Administration
(FHWA). It is now part of Standard Highway Signs (SHS), the companion volume to the MUTCD which gives full design details for signfaces. Initially, all of the alphabet series consisted of uppercase letters and digits only, although lowercase extensions were provided for each alphabet series in a 2002 revision of SHS. Series B through Series F evolved from identically named alphabet series which were introduced in 1927. Straight-stroke letters in the 1927 series were substantially similar to their modern equivalents, but unrounded glyphs were used for letters such as B, C, D, etc., to permit more uniform fabrication of signs by illiterate painters. Various state highway departments and the federal BPR experimented with rounded versions of these letters in the following two decades. The modern, rounded alphabet series were finally standardized in 1945 after rounded versions of some letters (with widths loosely appropriate for Series C or D) were specified as an option in the 1935 MUTCD and draft versions of the new typefaces had been used in 1942 for guide signs on the newly constructed Pentagon
Pentagon
road network. The mixed-case alphabet now called Series E Modified, which is the standard for destination legend on freeway guide signs, originally existed in two parts: an all-uppercase Series E Modified, which was essentially similar to Series E, except for a larger stroke width, and a lowercase-only alphabet. Both parts were developed by the California Division of Highways (now Caltrans) for use on freeways in 1948–1950. Initially, the Division used all-uppercase Series E Modified for button-reflectorized letters on ground-mounted signs and mixed-case legend (lowercase letters with Series D capitals) for externally illuminated overhead guide signs. Several Eastern turnpike authorities blended all-uppercase Series E Modified with the lowercase alphabet for destination legends on their guide signs. Eventually, this combination was accepted for destination legend in the first manual for signing Interstate highways, which was published in 1958 by the American Association of State Highway Officials and adopted as the national standard by the BPR. Uses of non-FHWA typefaces[edit]

Some traffic signs, such as the left-turn prohibition sign hanging from this gantry, are lit for better visibility, particularly at night or in inclement weather.

The US National Park
Park
Service uses NPS Rawlinson Roadway, a serif typeface, for guide signage; it typically appears on a brown background. Rawlinson has replaced Clarendon as the official NPS typeface, but some states still use Clarendon for recreational signage. Georgia, in the past, used uppercase Series D with a custom lowercase alphabet on its freeway guide signs; the most distinctive feature of this typeface is the lack of a dot on lowercase i and j.[16] More recent installations appear to include the dots.[17] The Clearview typeface, developed by US researchers to provide improved legibility, is permitted for light legend on dark backgrounds under FHWA interim approval. Clearview has seen widespread use by state departments of transportation in Arkansas, Arizona,[18] Illinois,[19] Kentucky, Maryland, Michigan, Ohio, Pennsylvania, Texas, and Virginia. The Kansas Turnpike Authority
Kansas Turnpike Authority
has also introduced Clearview typeface to some of its newer guide signs along the Kansas Turnpike, but the state of Kansas
Kansas
continues to use the FHWA typefaces for signage on its non-tolled Interstates and freeways. In Canada, the Ministry of Transportation for the Province of British Columbia specifies Clearview for use on its highway guide signs,[20] and its usage has shown up in Ontario

and on new 400-series highway installations in Hamilton, Halton and Niagara, as well as street signs in various parts of the province. The font is also being used on newer signs in Alberta, Manitoba, and Quebec.

road signs are generally influenced both by American and European practices. Warning signs are diamond-shaped with a yellow background for permanent warnings, and an orange background for temporary warnings. They are somewhat more pictorial than their American counterparts. This is also true for Canadian signage. Regulatory signs also follow European practice, with a white circle with a red border indicating prohibitive actions, and a blue circle indicating mandatory actions. White
White
rectangular signs with a red border indicate lane usage directions. Information and direction signs are rectangular, with a green background indicating a state highway, a blue background for all other roads and all services (except in some, where directional signage is white), and a brown background for tourist attractions. Before 1987, most road signs had black backgrounds – diamonds indicated warnings, and rectangles indicated regulatory actions (with the exception of the Give Way sign (an inverted trapezium), and Stop sign and speed limit signs (which were the same as today)). Information signs were yellow, and direction signage was green on motorways and black everywhere else. South America, Central America

vary from country to country. For the most part, conventions in signage tend to resemble United States signage conventions more so than European and Asian conventions. For example, warning signs are typically diamond-shaped and yellow rather than triangular and white. Some variations include the "Parking" and "No Parking" signs, which contain either a letter E or P, depending on which word is used locally for "Parking" (Spanish estacionamiento or parqueo, Portuguese estacionamento), as well as the Stop sign, which usually reads "Pare" or "Alto". Notable exceptions include speed limit signs, which follow the European conventions, and the "No Entry" sign, often replaced with a crossed upwards arrow. Colombia[edit] Traffic signs in Colombia are classified into three categories:

Warning signs Mandatory signs Information signs.[21]

Warning signs are very similar to warning signs in United States. They are yellow diamond-shaped with a black symbol (the yellow colour is changed to an orange colour in areas under construction). In certain cases, the yellow colour is shifted to fluorescent yellow (in the School

area sign and Chevron sign). Mandatory signs are similar to European signs. They are circular with a red border, a white background and a black symbol. Stop sign

and Yield sign

are as European, except the word "Stop" is changed for "Pare" and the Yield sign

has no letters, it is a red triangle with white centre. Information signs have many shapes and colours. Principally they are blue with white symbols and in many cases these signs have an information letter below the symbol. Suriname[edit] Road
Road
signs in Suriname are particularly modelled on the Dutch road signs since Suriname is a former Dutch colony, although traffic drives on the left unlike in the Netherlands. Automatic traffic sign recognition[edit] Cars are beginning to feature cameras with automatic traffic sign recognition, beginning with the Opel Insignia. It mainly recognizes speed limits and no-overtaking areas.[22] See also[edit]
