Abstract

The ice warning system for roads provides the motorist with a clear indication of impending icing. Obvious road markers such as sign posts, or additional posts at 50 to 100 m intervals along the road side, are fitted with temp-sensitive colour elements. The elements are constructed from material which changes colour with a change of temp. The warning devices are arranged so that a very obvious colour change, e.g. from light blue to orange occurs when the air temp. falls to around or below freezing point. A striped pattern provides an enhanced visual effect.

Description

Warnsystem bei Glatteisgefahr Warnsystem bei Glatteisgefahr Die Erfindung betrifft ein Verfahren, durch Farbveränderungan der Strassenbegrenzung die Kraftfahrer vor drohender Glatteisgefahr zu warnen.Warning system when there is a risk of black ice Warning system when there is a risk of black ice The invention relates to a method by changing the color of the road delimitation the motorists to warn of the threat of black ice.

Plötzlich auftretende Glatteisbildung führt häufig zu schweren Serienunfällen mit Millionenschäden sowie Schäden an Leib und Leben. Die Erfindung hat daher den Zweck, die Kraftfahrer r e c h t z ei t i g vor drohender Strassenglätte zu warenen.The sudden formation of black ice often leads to serious serial accidents with millions in damage as well as damage to life and limb. The invention therefore has the Purpose to warn drivers in time before the threat of slippery roads.

Es ist bekannt, dass schon lange Überlegungen und Bestrebung im Gange sind, zu diesem Zweck ein verlässliches Warnsystem zu finden. Alle Vorschläge bisher basierten auf technischen, d.h. mechanischen oder elektronischen Warneinrichtungen, die über Anzeigetafeln entlang gefährdeter Strassen die Kraftfahrer warnen sollen. Diese Lösungen scheitern an dem technischen und finanziellenAufwand.It is known that a long deliberation and endeavor has been underway are to find a reliable warning system for this purpose. All suggestions so far based on technical, i.e. mechanical or electronic warning devices, which are intended to warn drivers via display boards along endangered roads. These solutions fail because of the technical and financial outlay.

Die Aufgabe bestand daher darin, ein System zu finden, das bei geringstmöglichemAufwand eine breitgestreute Anwendungsmöglichkeit gestattet.The task was therefore to find a system that with the least possible effort allows a wide range of possible applications.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass durch eine temperaturempfindliche Farbveränderung der Strassenbegrenzungen ein Hinweis auf Glatteisgefahr erfolgt.The object is achieved according to the invention in that by a temperature-sensitive color change of the road limits an indication of There is a risk of black ice.

Die mit dieser Erfindung erzielten Vorteile ergeben sich wie folgt: Strassenbegrenzungen wie Leitplanken, Leitpfähle, Masten o.ä. werden im Abstand von 50 bis 100 m oder in beliebigen Abständen mit einer temperaturempfindlichen Farbkombination 1- z. B. hellblau -gestrichen. Bei einem Temperaturabfall auf den Gefriepunkt und darunter verändert sich die Farbe in einen deutlichen Gegensatz - z.B. orange.The advantages achieved with this invention are as follows: Road boundaries such as crash barriers, guide posts, masts, etc. are spaced apart from 50 to 100 m or at any distance with a temperature-sensitive Color combination 1- z. B. painted light blue. If the temperature drops to the Frozen and below, the color changes into a clear contrast - e.g. orange.

Warnsystem bei Glatteisgefahr Wenn also, wie in diesem Beispiel, entlang einer Fahrbahn plötzlich die Farbe "orange" aufleuchtet, bedeutet dies Glatteisgefahr bei einsetzendem Regen oder Nebel. Jeder Strassenbenutzer ist gewarnt und kann sein Verhalten danach einrichten.Warning system in case of risk of black ice If so, as in this example, along If the color "orange" suddenly lights up on a lane, this means there is a risk of black ice when it starts to rain or fog. Every road user is warned and can be Set up behavior afterwards.

Ein solches Warnsystem hat den Vorzug, dass es mit geringstem Kostenaufwand realisiert werden kann. Strassenbegrenzungenwerden in der Regel ohnehin gestrichen und es ist nur ein geringfugiger Mehraufwand notwendig, um eine Spezialfarbe in gewissen Abständen angubringen.Such a warning system has the advantage that it is very inexpensive can be realized. Road boundaries are usually deleted anyway and only a little extra work is required to get a special color in at certain intervals.
