Congestion-free Hessen 2015

Logo of the project

The congestion-free Hessen 2015 project was a medium-term strategy to avoid congestion in the state of Hesse . It was a combination of different traffic management systems .

aims

The Hessian state government had set itself the goal of freeing Hesse from traffic jams by 2015. Due to the expected high growth in motor vehicle traffic, it was no longer sufficient to enlarge motorways.

activities

Construction site management system (BMS)

In September 2003, the state of Hesse was the first state to implement a construction site management system that is being expanded in several steps.

In the first expansion stage of the BMS, all construction sites planned on motorways are electronically recorded. The daytime construction sites are subjected to a traffic assessment. For this purpose, the effects on road traffic are estimated. The anticipated traffic jam hours determined in this way are minimized by optimizing the construction work. This is done manually or with the rules stored in the system (e.g. “no daytime construction sites in the Rhine-Main area during the IAA ”).

Part of the BMS is also an automatic coordination of the internal administrative coordination processes to accelerate the measures.

In the further expansion stages, the assessment of permanent construction sites and the assessment of construction measures in the context of the network are planned.

DIANA

The core of the project is the introduction of the traffic information system "Dynamic Information And Navigation Assistance" (DIANA). The aim is to provide improved traffic information through mobile traffic data ( floating car data ).

At the start of the project in 2005, 100 vehicles were equipped with DIANA. The permanent transmission of real-time data directly from the DIANA vehicles to the Hessian traffic control center on the traffic situation on the route that the vehicle is traveling enables faster and more precise recording of the current traffic situation. The data obtained in this way supplement the recording of the traffic situation on the Autobahn in Hesse at fixed measuring cross-sections with the aid of induction loops or radar sensors.

This information is processed and used to create dynamic route guidance. DIANA participants are warned in good time of traffic jams on their route, for example, and are offered an alternative route.

Dynamic signs with integrated traffic jam information (DWiSta)

The use of traffic control systems is essential for avoiding traffic jams . H. the dynamic control of motor vehicle traffic depending on the current traffic situation.

While up to now mainly substitute variable signposts with mechanical rotating prisms have been used, dynamic signposts with integrated traffic jam information ( DWiSta ) with modern LED technology are to be used in the future .

Such systems have already been used on the A66 and A3 . What is special about these systems is that by specifying the congestion grounds and the (extended) travel times, a higher level of acceptance of the traffic control system can be achieved.

Temporary release of the hard shoulder

Since the change in the road traffic regulations on January 1, 2002, it has been possible to temporarily open the hard shoulder. This instrument is already being used in Hesse on a 68 km route (as of April 2010). After the Hessian summer vacation 2010, another 12 km (A5 south of Darmstadt) were released. Further routes are in preparation.

For safety, video surveillance is used to remove the release of the hard shoulder if motor vehicles stop. The number of accidents has even decreased as a result of this procedure, as the improved traffic flow reduces the number of risky situations.

The capacity of the motorways could be increased by approx. 25% (with three regular lanes) by opening the hard shoulder.

Activities of other federal states

Similar initiatives have also been started in other federal states. This includes u. a. the development of traffic information systems .

  • The BAYERNINFO project implemented the development of a supra-regional traffic information system. A dynamic traffic analysis and forecast as well as the creation of current traffic situation reports and timetable information for Bavaria takes place there . In connection with the expansion of the EFA electronic timetable information system into a state-of-the-art information system for public transport throughout Bavaria and the implementation of the “Bayernnetz für Radler” website with around 100 cycle paths (network length approx. 7,300 km), an information system across all modes of transport was created.
  • In North Rhine-Westphalia , the state government started an extensive catalog of measures as part of an “offensive against traffic jams in North Rhine-Westphalia ”. In addition, the “ Ruhrpilot ” is being implemented as a regional traffic management platform within the framework of a PPP model.
