Description

The present invention relates to a warning system according to the generic term of claim 1.

Although usually via traffic radio half hour the message delivered which motorways and expressways are currently not fully accessible it is, given a large number of such reports and not all due to the increasingly dense motorway network Road users, especially motorists, can access the relevant data and perceive information and also on driving behavior accordingly implement, so that Germany's drivers are often stuck in traffic.

In this context, it should also be considered that the motorways and expressways in Germany consistently with Provide signs on bypasses (so-called U-streets) are used in the event of a traffic disruption on the main route can be; however, motorists usually realize that too late an obstacle builds up in front of them or has already built up.

From the publication DE 28 24 019 A1 an optical-electronic traffic jam warning system is known which can be activated technically via traffic radio. This system is based on a turn signal system, which is attached to the emergency pillars of the motorway. A disadvantage of this system is that it does not offer any suggestions according to which the road user can avoid the traffic jam.

In the publication DE 41 02 381 A1 a traffic jam warning system or a warning system of the type mentioned is described. With this type of traffic management system, visual warning signs in the form of flashing warning signs are set up at prominent points on the motorway, in particular at exits and at driveways.

Each of the warning displays can be one own radio receiver included and directly above Be addressed by radio or with associated warning displays be combined into a group connected by lines, the central one common radio receiver is addressed.

The warning displays are flashing warning signs or designed as slat displays, which means there are additional ones Facilities provided through Radio can be addressed, which is perceived as disadvantageous.

In addition to the warning signs on departures and on driveways, in one embodiment according to the document DE 41 02 381 A1 additional warning lights are attached, which signal the traffic jam to the driver at a sufficiently large distance when approaching the end of the traffic jam.

Based on the disadvantages set out above and shortcomings as well as with appreciation of the state of the art outlined lies in the present invention based on the task of a warning system, in particular a traffic jam warning and diverting system, of the type mentioned at the beginning, in which increased Security and high economic efficiency can be achieved.

This task is accompanied by a warning system solved the features specified in claim 1. Advantageous configurations and appropriate further training of the present invention are characterized in the subclaims.

The basis of the invention Principle includes arranging traffic obstructions, in particular in traffic jams, for example via radio activatable warning signs on traffic signs, in particular at freeway exits or at freeway entrances.

The constellation of a two or multiple warning system, having

• - at least one on at least one on the next exit or driveway indicative first sign arranged first signal device, in particular early warning indicator or early warning light, and
• - at least one at at least one exit or driveway immediately indicating sign arranged second signal device, in particular second warning indicator or second warning light,

represents an advantageous embodiment of the present invention.

At least expediently the first signal device and / or the second signal device on already on streets, especially on highways or expressways, signs attached, for example attached.

In contrast to conventional warning systems is thus in the warning system according to the invention not assuming separate signs, Instead, it already saves existing ones in a cost-saving manner Signs, in particular existing departure and drive-up signs, with at least one signal device, in particular with at least one a warning light.

In an advantageous embodiment of the present invention will be the transceiver in the case the traffic obstruction of at least one higher level instance, for example from at least one traffic control center, from the Autobahn police and / or from traffic radio, in particular automatically in activity set.

Advantageously controls in case the traffic signal, the first signaling device automatically and / or automatically the second signal device, in particular the second signal device activated or deactivated by the first signal device or switched on or off by this.

Regardless of this can also the first signaling device automatically and / or automatically by controlled and / or activated the second signal device or deactivated, for example switched on or off.

By activating the first Signal device and / or the second signal device in the case The traffic obstruction is achieved on the traffic obstruction vehicles approaching the road, especially the motorway or expressway, can leave in time to on other roads to bypass the traffic obstruction.

Likewise, those vehicles - by one Feeder coming - on the parent Road, drive on the motorway or the expressway, for example want to be prevented from doing this.

A radio control of the first, especially on the signpost with exit or ascent notice attached signaling device and an automatic control or Switch on the second one, especially on the exit or driveway sign attached signaling device has the advantage that only one only signal device controlled by the higher-level entity becomes, which leads to a technical simplification of the overall system and is therefore cost-saving.

Advantageously, the first one Signal device and / or the second signal device as at least a flashing light, strobe light, spark light, lamp or illuminated lettering trained and gives at least one concise, eye-catching and memorable optical light signal.

In this case there is the technical solution according to the present Invention in an arrangement or in a system of signs that along the traffic road are provided and the next exit or driveway ads, with each sign indicating one for the guide of the vehicle provided clearly visible optical signaling device is.

Regardless of this or in connection the warning system can be used to intensify the warning function at least one more, i.e. at least a third, fourth etc. Have signal device between the first signal device and the second signal device and / or between the second Signal device and the traffic obstruction is arranged.

The following is the methodical Principle of operation of the present invention described:

To warn road users, especially on highways and expressways, at least works in the case one following at least one second signal device road section existing traffic obstruction, for example at least one Traffic jams, at least at first a transmitting / receiving device, in particular based on radio with at least one first signal device and / or with at least one a second signal device together.

Here is the first one, for example as an early warning indicator or designed as an early warning light Signal device on at least one first sign, in particular

• - on at least one to the next Exit and / or driveway signpost or
• - on at least one the next Announcing exit and / or driveway Notice board,

arranged.

Furthermore, the second signal device is on at least one of the first signs in the direction of the traffic route following second sign, especially on at least one immediately the sign indicating the exit and / or access, arranged. Accordingly, the second signal device can for example by one at at least one exit and / or driveway the highway or expressway act as arranged warning indicator or warning light.

After contacting the first and / or second signal device or after activation transmit the first and / or second signal device by the transmitting / receiving device the first signal device and the second signal device each at least one visual warning signal that in particular

• - by at least one flashing light, strobe light, spark light, lamp or Illuminated lettering and / or
• - by at least one additional Note "JAM AHEAD" with which the optical Signaling devices can be provided,

is generated and that the leader of one Means of transportation, for example the driver of a motor vehicle, prompted, for example, a bypass or To choose a detour route.

The present invention relates to finally the Use of at least one warning system, in particular at least one Congestion warning / diversion system, according to the above the way of regulating the flow of traffic on traffic routes, especially on highways and expressways.

As already discussed above, there are various possibilities for advantageously designing and developing the teaching of the present invention. For this purpose, on the one hand, reference is made to the claims subordinate to the independent claims, on the other hand, further refinements, features and advantages of the present invention are explained below with reference to the two by the 1 and 2 illustrated embodiments explained in more detail.

It shows:

1 a schematic representation of a first tes embodiment of a warning system according to the invention; and

2 in a schematic representation a second embodiment of a warning system according to the invention.

The same or similar configurations, elements or features are in the 1 and 2 provided with identical reference numerals.

In 1 is a first embodiment of a warning system 100 , in 2 a second embodiment of a warning system 100 ' for traffic routes 80 , namely a traffic jam warning and diversion system for highways and expressways.

Obtain to avoid unnecessary repetitions the following explanations regarding the configurations, features and advantages of the present invention (unless stated otherwise)

• - Both on the first embodiment of the warning system 100 according to 1
• - As well as the second embodiment of the warning system 100 ' according to 2 ,

When in 1 or in 2 congestion warning system shown 100 respectively. 100 ' is on a first sign 60 on the next motorway exit 82 indicates a first signal device 20 attached that as a concise optical signal 50 can send a yellow sparkle fire.

Has now been on the highway exit 82 in the direction 86 of the traffic route 80 A traffic accident occurs on the following freeway section and a traffic obstruction in the form of a traffic jam occurs in this freeway section due to this traffic accident 90 is formed, so the first signal device 20 from a higher authority 14 , namely by a traffic control center, the motorway police or traffic radio, is automatically activated.

So if towards 86 of the traffic route 80 in the section of the freeway that is the exit sign 60 with the optical signal to be switched on 50 follows, a traffic jam 90 has occurred, the optical signal device is switched on (as well as later switched off) 20 via radio 12 in such a way that

• - the one with the higher authority 14 in connection 16 standing, designed in the form of a base station 10a from the parent instance 14 is put into operation and
• - a receiving device 10b in the form of a on the optical signal device 20 attached antenna the radio signal 12 receives.

Furthermore is on a second sign 70 that on the nearby or imminent exit 82 indicates a second signal device 30 attached, which is also a distinctive optical signal 52 , namely sends a second same spark fire.

This optical signal 52 can also be provided with the message "traffic jam ahead" and is also only then by an analogue transceiver 10a . 10b activated (cf. first embodiment according to 1 ) if the section of the motorway ahead is blocked by a traffic obstacle 90 is blocked.

The yellow spark fire 50 respectively. 52 can also be replaced by any other optical signal; with regard to the design of the two signal devices 50 . 52 It is important that they are uniform so that the driver can memorize "Warning, traffic jam ahead".

As a possibility of attachment for the first signal device 20 The following motorway signs are provided for the early warning light:

• - Signpost with reference to exit to ... (see first sign 60 in 1 ) or
• - Notice board for the next exit (see first sign 60 in 2 ).

As a possibility of attachment for the second signal device 30 the following motorway signs are provided:

• - Exit from the motorway to ... (see second sign 70 in 1 ) or
• - Display of the exit from the motorway (see second sign 70 in 2 ).

At the in 2 shown warning system 100 ' is the first signaling device 20 , namely the first strobe light, on the first sign 60 , namely the notice board.

The second signal device 30 , namely the second strobe light, is on the second sign 70 , namely on the exit 82 indicating sign attached.

A third signal device 30 , namely the third flashing light, is the driveway on one 84 to the highway 80 indicating sign 70 ' appropriate.

In the second embodiment according to 2 becomes the first signaling device 20 on the signpost 60 from a central office 14 via radio 12 driven. This strobe light unit 20 then automatically controls all other flashing lights to be activated, that is to say the second signaling device 30 and the further (= third) signal device 40 so these flashing lights 30 . 40 no longer directly from headquarters 14 can be controlled.

For this purpose, the warning system is in the second embodiment 100 ' (see. 2 ) from the head office 14 via radio 12 controlled first signal device 20 , namely the flashing light, via a power cable 32 with the second signal device 30 and, from this second signal device 30 outgoing, via another power cable 42 with the third signal device 40 connected. The power cables 32 . 42 are each drawn as a dashed line, because they run underground and are therefore usually not visible.

By installing the third signaling device 40 that, for example, an optical signal 54 in shape

• - of yellow sparkling fire,
• - the Strobe light and / or
• - of additional Notice "Traffic jam ahead"

emitted at the driveways 84 on the highway 80 the drivers on the relief route or bypass 88 redirected to the next driveway.

This significantly reduces stress for drivers, not least because of overcrowded expressways 80 be relieved. Since the frequency and intensity of the "catch-up hunt" after a traffic jam, which is customary in traffic, unfortunately 90 are reduced, the risk of accidents is also reduced.

With the help of the warning system 100 . 100 ' the drivers are on the road section with the traffic jam 90 as soon as you reach the exit or driveway sign 60 . 70 respectively. 70 ' alerted and thus have the opportunity to avoid the traffic jam by using the exit sign 60 following exit 82 use or the driveway 84 do not use to over detour roads 88 at the traffic jam 90 get past.

The warning system is expedient 100 . 100 ' Installed at low cost and made public via suitable publicity media (for example "ADAC motorwelt", "AutoBild" etc.). The warning system 100 . 100 ' brings significant economic benefits in that many drivers avoid unnecessary waiting times, no unnecessary petrol is used by cars in traffic jams and the overall flow of traffic is improved.
