Description

Die Erfindung betrifft eine Anzeigeeinrichtung zur optischen Warnung eines von einer Hauptstraße in eine Nebenstraße abbiegenden Autofahrers vor einer sich der Nebenstraße parallel zur Hauptstraße annähernden Person, mit wenigstens einem Sensor zum Erfassen der Person und wenigstens einer bei Annäherung einer Person ein optisches Warnsignal abgebenden Leuchte.The invention relates to a display device for the visual warning of a motorist turning from a main road into a secondary road of a person approaching the secondary road parallel to the main road, with at least one sensor for detecting the person and at least one lamp emitting an optical warning signal when a person approaches.

Fig. 1 zeigt solch eine typische Verkehrssituation beim Abbiegen an einer Kreuzung von einer Hauptstraße in eine Nebenstraße in einer schematischen Draufsicht. Insbesondere zeigt Fig. 1 eine Hauptstraße HS mit einer unter Ausbildung einer Kreuzung sich rechtwinklig zur Hauptstraße HS erstreckenden Nebenstraße NS. Für den Zweck dieser Beschreibung dienen die Begriffe "Hauptstraße" und "Nebenstraße" lediglich der Unterscheidung der Straßen, stellen aber nicht zwingend eine Vorrangigkeit der einen Straße vor der anderen Straße dar. 1 shows such a typical traffic situation when turning at an intersection from a main road into a side road in a schematic plan view. In particular shows 1 a main road HS with a secondary road NS extending at right angles to the main road HS, forming an intersection. For the purpose of this description, the terms "main road" and "secondary road" are used only to distinguish between the roads, but do not necessarily imply a priority of one road over the other.

Zur Regelung des Verkehrsflusses sind im Kreuzungsbereich an der Hauptstraße HS und an der Nebenstraße NS mehrere Lichtsignalanlagen LSA installiert, die ein gefahrloses Abzweigen von der Hauptstraße HS in die Nebenstraße und/oder von der Nebenstraße NS in die Hauptstraße ermöglichen.To control the flow of traffic, several LSA traffic light systems are installed in the crossing area on the HS main road and on the NS side road, which enable safe turning from the HS main road into the side road and/or from the NS side road into the main road.

Des Weiteren sind zwei Autos bzw. Autofahrer A1, A2 dargestellt, die sich auf der Hauptstraße HS befinden, wobei der eine Autofahrer A1 im Begriff ist, von der Hauptstraße HS in die Nebenstraße NS einzubiegen.Furthermore, two cars or motorists A1, A2 are shown who are on the main road HS, one motorist A1 being about to turn from the main road HS into the side road NS.

Der Abbiegevorgang des Autofahrers A2 ist insofern gefahrträchtig, dass parallel zur Hauptstraße HS ein die Nebenstraße NS kreuzender Radweg RW verläuft, der von den Radfahrern R1, R2, R3 verwendet wird.The turning process of the motorist A2 is dangerous insofar as a cycle path RW, which crosses the secondary road NS and is used by the cyclists R1, R2, R3, runs parallel to the main road HS.

Während der Autofahrer A1 die in Fahrtrichtung vor ihm liegenden Radfahrer R2, R3 während des Abbiegens beobachten und durch eine an deren Bewegung angepasste Fahrweise berücksichtigen kann, bewegt sich der für den Autofahrer A1 entgegen seiner Fahrtrichtung zurückliegende Radfahrer R1 außerhalb dessen üblichen Blickfelds und bleibt daher beim Abbiegevorgang unbeachtet. Selbst bei Ausführung eines entgegen der Fahrtrichtung schwenkenden Schulterblicks mag ein sich schnell in Fahrtrichtung bewegender Radfahrer R1 nicht wahrgenommen werden, sodass es zu einer Kollision zwischen dem Autofahrer A1 und dem Radfahrer R1 kommen kann.While the car driver A1 can observe the cyclists R2, R3 lying in front of him in the direction of travel while turning and can take into account their driving style by adapting their movement, the car driver A1 moves in the opposite direction to his travel direction past cyclists R1 outside of his usual field of vision and therefore remains unnoticed when turning. Even if you look over your shoulder against the direction of travel, a cyclist R1 moving quickly in the direction of travel may not be noticed, so that a collision can occur between the motorist A1 and the cyclist R1.

Um diese Gefahrensituation möglichst zu vermeiden und entsprechende Unfälle zu verhindern, ist aus der EP 2 462 574 B1 bereits eine Lichtsignalanlage bekannt, die mit einem gegen die Fahrtrichtung des zu regelnden Verkehrs ausgerichteten Sensor ausgestattet ist, der eine in Fahrtrichtung gesehen rechts neben einem Fahrzeug sich der Lichtsignalanlage annähernde Person erkennt und darauf ansprechend das Aufleuchten oder Blinken einer zu dem grünen Signallicht benachbart angeordneten vierten Signallichts bewirkt.In order to avoid this dangerous situation as far as possible and to prevent corresponding accidents, the EP 2 462 574 B1 a traffic signal system is already known which is equipped with a sensor which is oriented against the direction of travel of the traffic to be controlled and which detects a person approaching the traffic signal system to the right of a vehicle, viewed in the direction of travel, and responds by lighting up or flashing a fourth signal light located adjacent to the green signal light Causes signal light.

Wenngleich diese Idee grundsätzlich zur Vermeidung der oben genannten Unfälle geeignet ist, hat es sich in praktischen Versuchen herausgestellt, dass die Lichtsignalanlage zwar bei entfernter Annäherung an die Kreuzung noch wahrgenommen wird, jedoch - wenn die Ampel grün zeigt - bei weiterer Annäherung nicht weiter beachtet wird und zwischenzeitlich sich der Lichtsignalanlage annähernde, in diese Gefahrenzone eintretende Personen nicht viel besser geschützt sind.Although this idea is fundamentally suitable for avoiding the accidents mentioned above, it has been shown in practical tests that the traffic signal system is still perceived when approaching the intersection from a distance, but - if the traffic light shows green - is no longer noticed when approaching further and in the meantime, people approaching the traffic light system and entering this danger zone are not much better protected.

Aufgabe der Erfindung ist es daher, eine Anzeigeeinrichtung für den Schutz einer zur Überquerung einer Straße oder eines Weges ansetzenden Person im Bereich einer Kreuzung zu schaffen, die vom Autofahrer besser wahrgenommen werden kann.The object of the invention is therefore to create a display device for the protection of a person preparing to cross a road or a path in the area of an intersection, which can be better perceived by the motorist.

Diese Aufgabe wird erfindungsgemäß durch die Anzeigeeinrichtung mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.According to the invention, this object is achieved by the display device having the features of claim 1 . The dependent claims reflect advantageous refinements of the invention.

Grundgedanke der Erfindung ist es, eine Anzeigeeinrichtung bereit- und so aufzustellen, dass diese während des Abbiegevorgangs vom Autofahrer wahrgenommen werden kann. Erfindungsgemäß ist die Anzeigeeinrichtung für den abbiegenden Autofahrer so ausgerichtet, dass dieser das von der Anzeigeeinrichtung abgegebene Lichtzeichen beim Abbiegevorgang selbst, d.h. während des Einbiegens von der Hauptstraße in die Nebenstraße sehen kann.The basic idea of the invention is to provide a display device and set it up in such a way that the driver can see it while turning. According to the invention, the display device is aligned for the turning motorist in such a way that he can see the light signal emitted by the display device during the turning process, ie while turning from the main road into the secondary road.

Hierfür ist die Anzeigeeinrichtung in Fahrtrichtung eines auf der Hauptstraße fahrenden Autofahrers im Kreuzungsbereich mit der Nebenstraße vor der Nebenstraße, also auf der Innenseite der vom Autofahrer zu beschreibenden Kurve, angeordnet und so eingerichtet, dass der Abstrahlwinkel der Anzeigeeinrichtung in den Kreuzungsbereich in einem Bereich zwischen einer quer zum Straßenverlauf der Hauptstraße verlaufenden ersten Achse und einer quer zum Straßenverlauf der Nebenstraße verlaufenden zweiten Achse liegt. Die Anzeigeeinrichtung befindet sich während des Abbiegevorgangs bei Rechtsverkehr also stets rechts vom Autofahrer (bei Linksverkehr entsprechend links vom Autofahrer) und strahlt von der Innenseite der Kurve im Wesentlichen quer zur Fahrtrichtung des abbiegenden Fahrzeugs ab. Insbesondere strahlt die Anzeigeeinrichtung in einen Bereich hinter einer vor der Abzweigung aufgestellten Lichtsignalanlage ab, die vom abbiegenden Autofahrer erkannt werden kann.For this purpose, the display device is arranged in the direction of travel of a motorist driving on the main road in the area of the intersection with the secondary road in front of the secondary road, i.e. on the inside of the curve to be described by the motorist, and set up in such a way that the beam angle of the display device in the intersection area is in a range between a first axis running transversely to the course of the main road and a second axis running transversely to the course of the secondary road. The display device is therefore always to the right of the driver during the turning process when driving on the right (or to the left of the driver when driving on the left) and radiates from the inside of the curve essentially transversely to the direction of travel of the turning vehicle. In particular, the display device radiates into an area behind a traffic light system set up in front of the junction, which can be recognized by the motorist turning off.

Hingegen wird ein Autofahrer, der sich auf der Hauptstraße befindet und nicht in die Nebenstraße einbiegen will, die Anzeigeeinrichtung nicht wahrnehmen, da dessen Blick in Richtung des Verlaufs der Hauptstraße ausgerichtet ist, in die im Wesentlichen auch die Anzeigeeinrichtung abstrahlt.On the other hand, a motorist who is on the main road and does not want to turn onto the side road will not see the display device, since his or her gaze is aligned in the direction of the main road, into which the display device also essentially radiates.

War es nach dem Stand der Technik zuvor nicht möglich, den abbiegenden Autofahrer vor einer herannahenden Person zu warnen, wenn dieser die vor der Abzweigung aufgestellte Lichtsignalanlage passiert hat, erscheint die erfindungsgemäße Anzeigeeinrichtung jetzt beim Schulterblick unmittelbar im Gesichtsfeld des Autofahrers, sodass eine Warnung problemlos wahrgenommen werden wird. Da erfindungsgemäß eine sich im "toten Winkel" des Autofahrers bewegende Person durch die während des Abbiegevorgangs für den Autofahrer jederzeit sichtbare Anzeigeeinrichtung angezeigt wird, ist das Unfallrisiko beim Abbiegen erheblich gesenkt.While it was previously not possible according to the prior art to warn the turning motorist of an approaching person when he/she had passed the traffic light system set up in front of the turn, the display device according to the invention now appears directly in the motorist's field of vision when he looks over his shoulder, so that a warning is easily perceived will be. Since, according to the invention, a person moving in the driver's "blind spot" is indicated by the display device which is visible to the driver at all times during the turning process, the risk of an accident when turning is significantly reduced.

Dabei ist die Anordnung der Anzeigeeinrichtung so gewählt, dass die erfindungsgemäße Anzeigeeinrichtung auf der Kurveninnenseite angeordnet ist, sodass der Autofahrer nicht etwa auf Lichtsignale oder Anzeigen (etwa auf der gegenüberliegenden Straßenseite) achten muss, die von der eigentlichen Gefahrenquelle ablenken.The arrangement of the display device is selected such that the display device according to the invention is arranged on the inside of the curve, so that the driver does not have to pay attention to light signals or displays (e.g. on the opposite side of the road) that distract from the actual source of danger.

Die erfindungsgemäße Anzeigeeinrichtung ist insbesondere unabhängig von einer Lichtsignalanlage operabel und einsetzbar. Beispielsweise kann eine erfindungsgemäß ausgestaltete Anzeigeeinrichtung auch an Kreuzungen aufgestellt werden, an denen keine Lichtsignalanlagen installiert sind, sodass auch an Kreuzungen ohne Ampeln die Sicherheit für kreuzende Personen, insbesondere Radfahrern, vor dem abbiegenden Verkehr erhöht ist. Darüber hinaus sorgt eine erfindungsgemäß eingerichtete Anzeigeeinrichtung, die speziell als Inselsystem autark betrieben werden kann, für eine erhöhte Sicherheit bei der Straßenüberquerung für den Fall, dass eine vorinstallierte Ampel ausfällt und die Verkehrssituation unter Umständen ohne Verkehrsregelung durch entsprechende Lichtsignalanlagen unübersichtlich ist.The display device according to the invention can, in particular, be operated and used independently of a traffic light system. For example, a display device designed according to the invention can also be set up at intersections where no traffic lights are installed, so that the safety of people crossing, especially cyclists, from turning traffic is increased even at intersections without traffic lights. In addition, a display device set up according to the invention, which can be operated independently as a stand-alone system, ensures increased safety when crossing the street in the event that a pre-installed traffic light fails and the traffic situation is unclear without traffic control by appropriate traffic signal systems.

Erfindungsgemäß ist also eine Anzeigeeinrichtung bzw. eine Anordnung mit einer Anzeigeeinrichtung zur optischen Warnung eines von einer Hauptstraße in eine Nebenstraße abbiegenden Autofahrers vor einer (aus der Fahrtrichtung des Autofahrers auf der Hauptstraße kommenden) sich der Nebenstraße parallel zur Hauptstraße annähernden Person vorgesehen, mit wenigstens einem Sensor zum Erfassen der Person und wenigstens einer bei Annäherung einer Person ein optisches Warnsignal abgebenden Leuchte, deren Abstrahlwinkel sich in den Kreuzungsbereich zwischen einer quer zum Straßenverlauf der Hauptstraße verlaufenden ersten Achse und einer quer zum Straßenverlauf der Nebenstraße verlaufenden zweiten Achse öffnend ausgerichtet ist. Die gedachten Achsen können beispielsweise jeweils im rechten Winkel zur Hauptstraße bzw. Nebenstraße verlaufen.According to the invention, a display device or an arrangement with a display device for optically warning a motorist turning from a main road into a side street of a person (coming from the direction of travel of the motorist on the main road) approaching the side road parallel to the main road is provided, with at least one Sensor for detecting the person and at least one light that emits an optical warning signal when a person approaches, the beam angle of which is aligned opening into the crossing area between a first axis running transversely to the road of the main road and a second axis running transversely to the road of the secondary road. The imaginary axes can, for example, each run at right angles to the main road or side road.

Die Begriffe "Hauptstraße" und "Nebenstraße" sollen für den Zweck der Beschreibung lediglich die Unterscheidung zwischen zwei Straßen und/oder Wegen deutlich machen. So kann es sich bei der "Nebenstraße" beispielsweise auch um eine Einfahrt oder Zufahrt zu einem Grundstück handeln, die von einem Fußgänger- oder Radweg gekreuzt wird, wobei die erfindungsgemäße Anzeigeeinrichtung im Kreuzungsbereich von Straße ("Hauptstraße") und Einfahrt/Zufahrt ("Nebenstraße") Verwendung findet.The terms "main road" and "secondary road" are intended only to clarify the distinction between two roads and/or lanes for purposes of description. For example, the "side street" can also be a driveway or driveway to a property that is crossed by a pedestrian or cycle path, with the display device according to the invention in the intersection area of the street ("main street") and driveway/driveway (" side road") is used.

Bevorzugt ist der Abstrahlwinkel der Leuchte selbst durch die erste Achse und die zweite Achse begrenzt. Dadurch wird der gesamte gefahrenträchtige Bereich, in dem der Autofahrer ohnehin einen Schulterblick durchführen muss, so ausgeleuchtet, dass der Autofahrer das durch die Anzeige abgegebene Warnsignal wahrnimmt.The beam angle of the lamp itself is preferably limited by the first axis and the second axis. As a result, the entire dangerous area, in which the driver has to look over his shoulder anyway, is illuminated in such a way that the driver perceives the warning signal emitted by the display.

Weiter bevorzugt ist die Anzeigeeinrichtung wenigstens teilweise als den Übergang von der Hauptstraße in die Nebenstraße begleitendes Geländer ausgebildet. Die Ausbildung der Anzeigeeinrichtung als Geländer hat den Vorteil, dass einerseits ein "Schneiden" der Kurve durch den Autofahrer verhindert, andererseits ein Schutz der sich hinter dem Geländer auf dem Radweg oder Fußgängerweg befindlichen Personen erzeugt wird. Dieses ist insbesondere an von LKW-Fahrern häufig befahrenen Kreuzungen von Vorteil.More preferably, the display device is designed at least partially as a railing that accompanies the transition from the main road to the secondary road. The design of the display device as a railing has the advantage that, on the one hand, the car driver prevents the curve from being "cut" and, on the other hand, the people behind the railing on the cycle path or pedestrian path are protected. This is particularly advantageous at intersections frequently used by truck drivers.

Die wenigstens eine Leuchte ist speziell auf Höhe eines PKW-Fensters angeordnet, wobei die wenigstens eine Leuchte auch auf Höhe eines LKW-Fensters angeordnet sein kann. Besonders bevorzugt sind jedoch zwei auf unterschiedlichen Höhen angeordnete Leuchten vorgesehen, sodass sowohl PKW-Fahrer als auch LKW-Fahrer das optische Warnsignal wahrnehmen können.The at least one lamp is specifically arranged at the level of a car window, it being possible for the at least one lamp to also be arranged at the level of a truck window. However, two lights arranged at different heights are particularly preferred, so that both car drivers and truck drivers can perceive the visual warning signal.

Die auf Höhe eines PKW-Fensters angeordnete Leuchte befindet sich ungefähr im Bereich zwischen etwa 0,90 m und etwa 1,30 m Höhe gemessen vom Straßenbelag. Die auf Höhe eines LKW-Fensters angeordnete Leuchte befindet sich ungefähr im Bereich zwischen etwa 2,10 m und etwa 2,70 m Höhe gemessen vom Straßenbelag.The lamp, which is arranged at the level of a car window, is approximately in the range between approximately 0.90 m and approximately 1.30 m above the road surface. The lamp, which is arranged at the level of a truck window, is approximately in the range between approximately 2.10 m and approximately 2.70 m above the road surface.

Nach einer weiteren bevorzugten Ausgestaltung ist die wenigstens eine Leuchte als Anzeige ausgebildet. Die Anzeige kann beispielsweise als Bildschirm ausgebildet sein. Insbesondere kann die Anzeige als Lauflicht ausgebildet sein.According to a further preferred embodiment, the at least one light is designed as a display. The display can be in the form of a screen, for example. In particular, the display can be designed as a running light.

Insbesondere ist die wenigstens eine Leuchte konvex ausgebildet. Durch diese Ausgestaltung wird gleichfalls ein Geländer mit den oben genannten Vorteilen geschaffen.In particular, the at least one lamp is of convex design. A railing with the advantages mentioned above is also created by this configuration.

Die Anzeigeeinrichtung weist bevorzugt eine den dem Kreuzungsbereich diagonal gegenüberliegenden Quadranten wenigstens teilweise ausleuchtende Beleuchtungseinrichtung auf. Mithilfe dieser Ausbildung wird eine sich an den Kreuzungsbereich annähernde Person bei Dunkelheit besser wahrgenommen.The display device preferably has a lighting device that at least partially illuminates the quadrant diagonally opposite the crossing area. With the help of this training, a person approaching the crossing area is better perceived in the dark.

Die Anzeigeeinrichtung weist weiter bevorzugt auf der ihrer Außenseite gegenüberliegenden (Innen-) Seite, also dem Radweg zugewandt, ein Schild oder eine Anzeige auf, die die Person, die sich der Nebenstraße nähert, auf die Gefahrensituation hinweist.The display device also preferably has a sign or display on the (inside) side opposite its outside, ie facing the cycle path, which informs the person approaching the secondary road of the dangerous situation.

Des Weiteren ist eine die Anzeigeeinrichtung mit Energie versorgende Photovoltaikanlage vorgesehen, sodass eine autarke Steuerung der Einrichtung ermöglicht ist.Furthermore, a photovoltaic system that supplies the display device with energy is provided, so that the device can be controlled autonomously.

Schließlich ist die Anzeigeeinrichtung so eingerichtet, dass die zu erfassende Person bzw. erfasste Person ein Zweiradfahrer, insbesondere ein Radfahrer, ist. Hierbei wird insbesondere die Richtung der Bewegung, aber bevorzugt auch die Geschwindigkeit oder die Geschwindigkeitsänderung der Person erfasst.Finally, the display device is set up in such a way that the person to be detected or the person detected is a two-wheeler rider, in particular a cyclist. Here, in particular the direction of the movement, but preferably also the speed or the change in speed of the person is detected.

Fig. 2 zeigt eine schematische Draufsicht auf eine Kreuzung mit einem ersten Ausführungsbeispiel gemäß der vorliegenden Erfindung dar. 2 Fig. 12 shows a schematic plan view of an intersection with a first embodiment according to the present invention.

Im Wesentlichen zeigt Fig. 2 die bereits für Fig. 1 beschriebene Verkehrssituation mit dem Unterschied, dass der Autofahrer A1 vor dem Radfahrer R1 durch die besonders bevorzugt ausgestaltete Anzeigeeinrichtung AE gewarnt ist.Essentially shows 2 the already for 1 described traffic situation with the difference that the motorist A1 is warned of the cyclist R1 by the particularly preferably configured display device AE.

Die Anzeigeeinrichtung AE ist insbesondere als Geländer ausgebildet und weist eine konkav ausgebildete Leuchte in Form einer Anzeige auf. Die Anzeigeeinrichtung ist dabei auf der Innenseite der vom Autofahrer A1 während des Abbiegevorgangs zu fahrenden Kurve angeordnet, sodass die Anzeigeeinrichtung AE während des Schulterblicks des abbiegenden Autofahrers immer in dessen Gesichtsfeld ist.The display device AE is designed in particular as a railing and has a concave lamp in the form of a display. The display device is arranged on the inside of the curve to be driven by the motorist A1 during the turning process, so that the display device AE is always in the driver's field of vision when he looks over his shoulder.

Die Anzeigeeinrichtung AE weist einen Sensor zum Erfassen der Person R1, in diesem Fall ein Radfahrer, auf, wobei von der Anzeigeeinrichtung AE bei Annäherung der Person R1 - wie gezeigt - ein optisches Warnsignal abgegeben wird, das sich an den von der Hauptstraße HS in die Nebenstraße NS abbiegenden Autofahrers A1 richtet.The display device AE has a sensor for detecting the person R1, in this case a cyclist, with the display device AE when the person R1 approaches - as shown - an optical warning signal is emitted, which is reflected in the main road HS in the Side road NS directs motorists turning off A1.

Aufgrund der konvexen Ausgestaltung der Anzeige der Anzeigeeinrichtung ist der Abstrahlwinkel der das optische Warnsignal abgebenden Leuchte sich in den Kreuzungsbereich zwischen einer quer zum Straßenverlauf der Hauptstraße HS verlaufenden ersten Achse und einer quer zum Straßenverlauf der Nebenstraße NS verlaufenden zweiten Achse öffnend ausgerichtet.Due to the convex design of the display of the display device, the beam angle of the lamp emitting the visual warning signal is aligned opening into the crossing area between a first axis running transversely to the road of the main road HS and a second axis running transversely to the road of the secondary road NS.

Zur Verdeutlichung zeigt Fig. 3 eine Detailansicht der in Fig. 2 dargestellten Kreuzung. Die quer zum Straßenverlauf der Hauptstraße HS verlaufende erste Achse X und die quer zum Straßenverlauf der Nebenstraße NS verlaufende zweite Achse Y begrenzen den Abstrahlwinkel, dass sich der Autofahrer etwa im rechten Winkel zur Anzeigeeinrichtung AE befinden muss, um das Warnsignal wahrnehmen zu können.For clarity shows 3 a detailed view of the in 2 shown intersection. The first axis X, which runs transversely to the course of the main road HS, and the second axis Y, which runs transversely to the course of the secondary road NS, limit the beam angle so that the driver must be approximately at right angles to the display device AE in order to be able to perceive the warning signal.

Zur weiteren Verdeutlichung ist in Fig. 4 ein weiteres Ausführungsbeispiel gemäß der vorliegenden Erfindung dargestellt, bei dem die Anzeigeeinrichtung entgegen der Fahrtrichtung des Autofahrers A1 entlang der Hauptstraße HS verlängert ist. Der gestrichelt dargestellte Bereich ist der Bereich, in dem das Warnsignal der Anzeigeeinrichtung AE von dem Autofahrer A1 wahrgenommen werden kann. Der Abstrahlwinkel der Leuchte ist dabei durch gedachte, rechtwinklig zur Hauptstraße HS und Nebenstraße NS verlaufende Achsen begrenzt. Schließlich zeigt Fig. 5 eine schematische Seitenansicht einer besonders bevorzugt ausgestalteten Anzeigeeinrichtung AE gemäß der vorliegenden Erfindung.For further clarification, in 4 a further exemplary embodiment according to the present invention is shown, in which the display device is extended along the main road HS in the opposite direction of travel of the motorist A1. The area shown in dashed lines is the area in which the warning signal of the display device AE can be perceived by the motorist A1. The beam angle of the lamp is limited by imaginary axes running at right angles to the main road HS and side road NS. Finally shows figure 5 a schematic side view of a particularly preferably designed display device AE according to the present invention.

Die Anzeigeeinrichtung AE weist eine Säule S mit in zwei unterschiedlichen Höhen angebrachten Leuchten L1, L2 auf. Die niedrig angeordnete Leuchte L1 ist zur Warnung von PKW-Fahrern eingerichtet, wohingegen die hoch angeordnete Leuchte L2 zur Warnung von LKW-Fahrern eingerichtet ist.The display device AE has a column S mounted at two different heights L1, L2 light up. The low-mounted lamp L1 is designed to warn car drivers, whereas the high-mounted lamp L2 is designed to warn truck drivers.

Wie für die niedrig angeordnete Leuchte L1 gezeigt, kann die wenigstens eine Leuchte L1. L2 als Lichtband ausgebildet sein, wobei mittels Piktogrammen auf eine sich nähernde Person, beispielsweise ein Radfahrer, aufmerksam gemacht werden kann.As shown for the low mounted lamp L1, the at least one lamp L1. L2 can be designed as a light band, with pictograms being able to draw attention to an approaching person, for example a cyclist.

Die in Fig. 5 dargestellte Anzeigeeinrichtung AE weist darüber hinaus eine Photovoltaikanlage PV auf, die den Betrieb der Anzeigeeinrichtung als autarkes Inselsystem ermöglicht. Der Sensor zum Erfassen der sich der Nebenstraße NS parallel zur Hauptstraße HS annähernden Person ist nicht dargestellt. Weitere zur Steuerung der Anzeigeeinrichtung AE benötigte Komponenten können vorteilhaft in der Säule S, vor einem Zugriff von außen geschützt, angeordnet sein.In the figure 5 The display device AE shown also has a photovoltaic system PV, which enables the display device to be operated as a self-sufficient stand-alone system. The sensor for detecting the person approaching the secondary road NS parallel to the main road HS is not shown. Other components required to control the display device AE can advantageously be arranged in the column S, protected from external access.
