A dynamic signpost with integrated traffic jam information , dWiSta for short , is a display system in Germany that forwards traffic information to road users. The display boards are located on gantries and are set up in front of motorway junctions or motorway junctions in Germany .

In various German federal states, the display system consists of a static part that contains the direction arrows and motorway numbers, and two lighting display blocks , one each for the straight ahead direction and one for the turning direction. Each block consists of a field for predefined warning notices, such as construction site , general hazard and traffic jams , as well as symbols such as the stadium symbol, a field for the diversion arrow and a three-line, freely programmable text field. Some federal states use a single freely programmable graphic field.

The first displays of this type were built in 2005 in Hessen at the Wiesbadener Kreuz and Mönchhof-Dreieck .

application

Bavaria

Between 1998 and 2003 the first freely programmable, dynamic information boards were developed as part of the Mobinet research project and installed on the A 8 West, the Eschenrieder Spange in the direction of Munich. With these freely programmable changing text displays, traffic in the direction of Munich can alternatively be directed via the A 99 motorway ring to the Ludwigsfeld junction and from there via Dachauerstraße to the Mittlerer Ring if the main route is overloaded in the city center direction Verdistraße and Arnulfstraße .

Hesse

Since 2005, the dynamic information boards have been used in Hesse as part of the Hesse 2015 traffic jam-free campaign to direct traffic. The advantage of these displays is that, in addition to the redirection, additional information such as B. the reason for the diversion as well as the expected loss of time that can be given to drivers. This is intended to further increase the acceptance of diversion recommendations and thus the efficiency of the advertisements so that the traffic is distributed as best as possible in the network. The control of the Hessian network control systems is based on the current traffic situation around the clock by the Hessen traffic control center in Frankfurt .

The close-knit motorway network in Hesse has many alternative routes and is therefore particularly suitable for the use of network control systems. So z. B. on the parallel motorways 5 and 67 on the Bergstrasse variable signposts for traffic-dependent control of traffic in the network have been used for more than 30 years. The same applies to many other motorway routes in the Rhine-Main area . In 2018 there were a total of 57 dWiSta advertisements in Hessen.

North Rhine-Westphalia

The first 38 dWiSta advertisements were set up in 2005 in the course of the 2006 soccer World Cup in Germany on the Cologne motorway ring consisting of the A 1 , A 3 and A 4 and their large feeder roads A 57 and A 59 . The Cologne facility was expanded in 2008 by four panels, two each in the direction of Olpe and Mönchengladbach , at Kreuz Kerpen . Furthermore, in the same spring, the two panels on the A1 near Cologne-Lövenich in the direction of Euskirchen were dismantled due to the construction of a noise protection tunnel. The two boards were put back into operation in an adapted form in autumn 2008 at the Heumarer Dreieck needle eye in the direction of Frankfurt (A 3), Aachen (A 4) and Bonn (A 59).

In the same year, the greater Düsseldorf-Mönchengladbach area was included with a total of 19 panels - mainly in the direction of Düsseldorf at the crosses Breitscheid , Hilden , Meerbusch , Neersen , Neuss-Süd and Neuss-West . In addition, a single board was installed at the Düsseldorf-Nord junction to inform cars about the backlog at Mörsenbroicher Ei .

The Münsterland and the eastern Ruhr area were integrated into the control system in 2011 through 10 locations. The boards are located in pairs at the intersections Lotte / Osnabrück in the direction of Dortmund, Schüttorf in the direction of Osnabrück, Wuppertal-Nord in the direction of Bremen and Hagen and at the Bottrop motorway triangle in the direction of Hanover.

Until the opening of the Leverkusen traffic control center, the boards were controlled manually by the traffic control centers in Cologne and Arnsberg . Since April 29, 2013, the dWiSta boards (manual) and the traffic control systems (automatic or manual) have been controlled centrally for all of North Rhine-Westphalia from the traffic control center in Leverkusen. The basis for the control is the minute-by-minute information about the traffic situation on the autobahns obtained by the State Office for Road Construction North Rhine-Westphalia .

Hamburg

Such a system has also been in operation in the greater Hamburg area since May 2006. Originally intended to direct traffic to the football World Cup, it is now used to indicate traffic jams and disruptions on and around the Elbe tunnel in Hamburg. The boards are set up at the Horster Dreieck on the A 1 and A 7 in the south and at the Neumünster-Süd junction in the north. So it is possible to bypass the affected area on the A 1, A 21 and B 205 .

Lower Saxony

dWiSta are installed near Hanover on the A2 at the Hanover-Herrenhausen junction and the Hanover-Ost motorway junction and in Hanover on the B 6 , the West Schnellweg , in front of the Schwanenburg junction and the B 65 , the Südschnellweg , in front of Hildesheimer Straße.

Rhineland-Palatinate

Around the state capital Mainz , dWiSta have also been set up in front of the Mainzer Ring , since 2012 at the latest . These are located on the A 60 in front of the Mainz triangle when coming from Bingen, and on the A 63 in front of the Mainz-Süd junction when coming from Alzey.

  • dWiSta just before the Mainz-Süd motorway junction. Here is the indication of a traffic jam on the A 60 in the direction of Frankfurt with the recommendation to drive via Wiesbaden and the A 66 to Frankfurt (2012)

  • The same display board this time with a diversion notice because of the closed Schiersteiner Bridge in February 2015.

Norms and standards

The instructions for the uniform design and application on federal highways - dynamic signposts with integrated traffic jam information (dWiSta) form the legal framework for setting up the signposts in Germany.
