A delineator post (in Austria delineator post , colloquially also delimitation post or road delimitation post ) is a traffic device that serves to delimit the roadway and to better recognize its course. The German StVO names the delineator post as sign 620 in Section 43 . In Austria, use is regulated in Section 57 of the StVO .
nature
In many cases today, delineator posts are made of plastic, but there are also variants made of wood, concrete and sheet steel. In addition to the body, the reflectors attached on both sides make the effect of the delineator post.
In Austria a delineator model is used, which u. a. has a color symbol in which a red rectangular reflector is mounted on the front or right and a white rectangular reflector is mounted on the rear or left. These reflectors symbolize the rear lights of the vehicles in front on the right-hand side and the headlights of the oncoming vehicles on the left.
The model used in Germany and in a similar form in many other European countries consists in Germany of a 12 centimeter wide and 1 m high (above the edge of the road), hollow, triangular plastic body, which is beveled at the top towards the road, one attached parallel to it , 25 cm wide bandage made of black plastic film (day license plate) and the reflectors embedded in it (front and right a rectangular reflector, white; behind or left two smaller round reflectors, white), which represent the night license plate (reflex sign). The German delineator post in its current form was introduced in West Germany in March 1957. A very similar delineator was introduced in the GDR with the TGL 12096/05, which became binding on July 1, 1974 . Even before the planned entry into force of a new edition of TGL 12096/05 from June 1989, which provided for a slight change to the delineator posts and was supposed to come into effect on February 1, 1990, this was declared null and void, as the GDR was overrun by the events of the turning point .
In Switzerland, square, white reflectors are used on the left on motorways with no oncoming traffic. The body of the delineator post is rounded in Switzerland.
At road junctions, the corner guide posts are given yellow reflectors. Sections that re-enter the roadway are also given delineator posts with yellow reflectors.
The delineator posts introduced in the GDR in 1974 were largely identical to the posts used in the Federal Republic of Germany since 1957. The only difference was that in curves the delineator posts on the outside of the curve were fitted with red reflectors and the bandage on these posts was also made red instead of black. The guidelines of both countries stipulated that the delineator posts could also be cast from concrete. In West Germany , however, the manufacture of delineator posts mainly from plastic began relatively early.
function
Delineator posts make an important contribution to road safety, especially in fog, snow and darkness .
Red, blue or blue-white wildlife warning reflectors are often attached to the delineator posts on stretches with an increased risk of wildlife crossing . At dusk or at night, these direct the headlights into the side of the road and also cause wide dispersion. The game perceives the restless rays of light and shrinks back.
A small black arrow pointing in the direction of the nearest emergency telephone can be attached to delineator posts. Snow signs are put up in snowy areas in winter . They act as delineators when there is a lot of snow or when snow drifts . In some parts of Germany, delineator posts also serve as milestones or station signs . Then on the right-hand side the number of kilometers and the street number as well as sometimes the section number of the kilometers are attached.
Manufacturing
Modern delineator posts for German roads are made of low-pressure polyethylene using injection molding , extrusion or blow molding technology . Delineator posts consist of the delineator body, the cap and reflectors (multi-chamber or glass bead reflectors). Delineator bodies can be set up hollow or stabilized with profile cores.
Lineup
In Germany, delineator posts are set up 50 centimeters from the outermost paved edge of the road surface and, as a rule, at a longitudinal distance in a straight line and level of 50 meters (in Austria 33 meters). In tight curves and confusing crests, depending on the radius or radius, the delineator posts are closer to each other. As a rule of thumb, there should always be at least five delineator posts visible on every side of the road - in curves of less than 200 meters on the outside of the curve.
In the case of multi-lane roads with divided lanes, for example motorways, delineators are only set up on the right-hand side of each lane.
Other countries
- Germany, Estonia, Finland, France, Israel, Italy, Latvia, Liechtenstein, Luxembourg, North Korea, Norway, Poland, Portugal, Sweden, Switzerland, the Czech Republic, Ukraine and Hungary use a rectangular reflector on the right and two smaller round reflectors on the back and left.
- In France and Monaco, the delineator posts have the same reflector on both sides.
- In Italy, the right delineator post has a red reflector, the left a white reflector. The same applies to the Netherlands, Austria (called the Leitpflock here), Hungary, Slovenia, Croatia, Greece, Russia, Belarus, Ukraine, Poland, Romania, Bulgaria and Turkey.
- In Great Britain and Australia, the left delimiter has a red reflector, the right a white reflector.
- Belgium, Denmark and Lithuania use yellow reflectors on the right and white on the left.
- In Spain the right marker post has one rectangular, yellow reflector, the left two round white ones.
- In the Czech Republic and Slovakia the right delineator post has two yellow reflectors and the left delimiter post has one white reflector.
- In China, USA and Canada the right delineator post has a white and the left a yellow reflector.
- As part of the standardization for European products, test regulations with EC standards are in progress.
history
For country roads in the Federal Republic of Germany until the 1960s, black and white painted guide pegs were used to mark the lane. Rather and parallel to this, guide stones (curbstones) have been known since the beginning of modern traffic , which can still be found here and there today and which were quickly displaced with the advent of the guide posts. The new delineator posts were created in accordance with the new guidelines established in 1957. The decisive factor in the development was the Kunzelmann company in Unteralpfen , which over the years developed an ingenious patent that is still in use today. Another system to be produced in series, whereby the delineator posts functioned according to a “standing up man” principle, could not be implemented. The wooden guide pegs, especially in rural western Germany, had not completely disappeared until the 1970s and are still used occasionally today.
