Road signs in Greece

Greek road signs P-2, P-28 and П-21 in Pefki, Attica.

Road signs in Greece are regulated by the Ministry of Transport and the Hellenic Traffic Police, according to the Greek Highway Code.

Signs follow the general European conventions concerning the use of shape and colour, for every sign category. Signs indicating dangers are triangular with a red border, those giving orders are almost all circular (white on blue for mandatory instructions, black on white with a red border for prohibitions), and those providing information are rectangular. Most signs use pictograms to convey their particular meaning.

As is customary in European countries, all signs are partly or fully reflectorized or are provided with their own night-time illumination. Signs used for temporary regulations may have an orange background colour.

Greek road signs depict people with realistic (as opposed to stylized) silhouettes. All signs are identified by a Greek capital letter (for each category) and a number. Signs that indicate the same meaning but in a different direction have the same capital letter and number but are additionally differentiated by a lowercase letter (e.g. α, β, γ, δ, ... or α for left and δ for right).

Greece acceded to the Vienna Convention on Road Signs and Signals on December 18, 1986. ^[1]

History

Roman milestone (milliario) from Boeotia (2 century BC)

The history of road signaling in Greece dates back to Antiquity. The first road signaling included marble columns with the head of Hermes, protector of the wayfarers. Those signs were known as ἑρμαῖ ("Hermai"). ^[2] There were also milestones for measuring street length in stadions. ^[3] Similar columns were also used in Roman times, but had miles as a unit of measurement.

The first road signage on Greek roads with contemporary signs was made in 1924 by ELPA (Elliniki Leschi Periigiseon kai Aftokinitou, lit. translated: Hellenic Club of Tours and Car), ^[4] which took over the road network's signage until 1957, when it was taken over by the state. ^[5] The signs were subject to the provisions of the Geneva Protocol on Road Signs and Signals.

On July 25, 1962, and with Government Gazette A '110/62, it was announced in paragraph 1 of article 14 that "by joint decisions, issued by the Ministers of Transport, Public Works and Interior, all matters relating to the road signs, road markings, the type of signals, the characteristics of the road signage and the manner of its application shall be defined," while in paragraph 2 of the same article that "the provisions of the International Geneva Protocol on Road Signs and Signals of September 1949, with its supplements, are temporarily valid and up-to the apply of the referenced of the paragraph 1 of this article."

Finally, on July 6, 1974, 12 years after the initial announcements and with the Government Gazette B '676/74, the first serious signaling standards were established, which are still valid today. ^[6] It was the first time that sign diagrams were included in a Government Gazette. Since the publication of the relevant Government Gazette, the "provisions of paragraph 2 of article 14 of Law 4332/62 "on the ratification of the Road Traffic Code" have been abolished. However, within five years of its publication, six of the old signs from the Geneva Protocol were still valid, as "temporarily preserved signs."

The ΠΤΠ (Πρότυπες Τεχνικές Προδιαγραφές – Standard Technical Specifications) Σ301-75, and Σ301-302-75 (ΦΕΚ 99 B '/ 1976) established the quality of the aluminum of the sign, the ΠΤΠ of ΦΕΚ 1061 B' / 1980, as corrected by the order BM5 / 0/40229 / 27-10-1980 the support poles, the ΠΤΠ of the ΦΕΚ 589 / Β / 1980 the signalling of performed intercity road works, the ΠΤΠ of the ΦΕΚ 121 / Β / 1983 the signalling of performed city road works, the ΠΤΠ Σ310 and Σ311 the membranes of the signs, the technical specification ΔΚ8 of ΕΗ3 / 0/107 / 22-1-1976 the poles for eccentric plates and the Greek standard ΕΛΟΤ- 743/87 the conversion of the Greek alphabet into Latin characters for the information signs, the Technical Description Δ3γ / 0/15/11-Ω / 28-2-1991 the illuminated signs, the Directive of ΔΜΕΟε / οικ / 720 / 13-11-92 the issues of road signs that are not covered by the previous specifications, the Community Directives and the corresponding Circulars of the Ministry TEM and the KME and ΤΣΥ the signaling and the types of safety equipment on the motorways and the relevant legislation of the Highway Code for advertisement signs. ^[2] At the same time, in 1976 and 1981, the Katharevousa and the Polytonic System, respectively, were abolished and replaced by new dialects and writing systems (Dimotiki and Monotonic). The Road Design Studies Instructions (OMOE) for the Motorway Signs and Signals (ΚΣΑ) and for the Marking of Performed Works (ΣΕΕΟ), concern the signs for these issues. (ΦΕΚ 905/2011 / B ') Finally, many recent laws (mainly laws of the Highway Code), have introduced new signs of various categories, which mainly concern vehicles that appear for the first time (e.g. trams or electric cars).

Design

Font

The font on the signs since 1974 is Transport, which also appears on the signs of other European countries. On motorways, the DIN 1451 font is used.

Language

The signs in Greece are in two languages: Greek (Greek Alphabet) and English (Latin Alphabet). Previously, the signs were in Katharevousa and used the Polytonic system, until 1976 and 1981, which were replaced by the Demotic and Monotonic systems respectively.

Retroreflection

Signs during the night are either:

• Internally illuminated – that is, of suitable translucent materials, illuminated by internal illumination systems. The application of these signs is restricted mainly to urban areas and to specific high-risk interurban networks.
• Externally illuminated – that is, they are illuminated by lamps facing them. These signs are applied at places where the light beam of cars is difficult to reach, such as the road sign gantries.
• With reflective materials – that is, part or all of which is of a suitable reflective film. They may not be reflective (at roads that are lit at night), semi-reflective (only symbols are reflective) or fully reflective (except symbols).

Finally, there are fluorescent reflective membranes, used in special circumstances, as a backdrop for school signs or signs indicating significant hazards.

Material

According to ΦΕΚ 99/76 B, the plates are made of aluminum sheets, "of alloy type AIMg 2 according to DIN 1725 Blatt I" or aluminum "type SIC 114 according to BS 873: PART 1: 1970 > 3 mm." To prevent corrosion, "they are calculated with a safety factor in terms of their mechanical strength, above 1.61." ^[7]

Poles

According to ΦΕΚ 1061 B '/ 1980, the poles of the signs are metal and are made of steel pipes or pipes made of aluminum alloy. The steel pipes have Carbon (0.17% to 0.30%), Sulfur (0.050% to 0.060%) and Phosphorus (0.050% to 0.060%), while the aluminum pipes, which are made of type 6005-A aluminum alloy according to the French AFNOR specification, silicon (0.60% to 0.90%), iron (0.35% maximum), manganese (0.50% maximum) and magnesium (0.40% to 0.70%) and their height is about 2.50 to 3.30 meters (8.2 to 10.8 ft). ^[8] The poles are usually made of steel, in the form of hollow beams, or of lightly reinforced concrete in circular sections. Two or more poles can also be used on larger signs. ^[6]

Dimensions

The signs have the following sizes: ^[9]

1. Small – the circular ones have a diameter of 450 millimeters (18 in), the equilateral triangular sides 600 millimeters (24 in), the informative ones with letters height 100 millimeters (3.9 in) and the octagonal STOP diameter 600 millimeters (24 in). They are found mainly in villages, small towns, private and rural roads, as well as in private areas. They are rarely placed on provincial roads, and if approved by the Competent Service.
2. Medium – the circular ones have a diameter of 650 millimeters (26 in), the equilateral triangular sides 600 millimeters (24 in), the informative ones with letters height 100 millimeters (3.9 in) and the octagonal STOP diameter 900 millimeters (35 in). They are found mainly in large cities and on provincial and / or national roads.
3. Large – the circular ones have a diameter of 900 millimeters (35 in), the equilateral triangular sides 1,200 millimeters (47 in), the informative ones in letters height 200 millimeters (7.9 in) and the octagonal STOP diameter 1,200 millimeters (47 in). They are found mainly on expressways.

On motorways, the size of the sign and the letters, as well as the font, require special treatment due to the different driving requirements on these roads. ^[9]
