State of the art

The Development of road traffic is by an increasing Traffic, high air pollution and environmental pollution characterized. The number of traffic jams and the traffic density take clear and continued to unstoppable. Also improved traffic regulations with intelligent traffic lights or other traffic engineering measures So far, this development has not been sustainable. At the same time are the requirements for safety equipment such as roadway boundaries and soundproofing continued to rise. The interaction of these factors results in more and more channels or tunnel-like road conditions. In front everything on these safe and soundproofed roads harmful exhaust gases and particles such as nitrogen oxides, Sulfur compounds or carbon black particles not included in the Atmosphere can escape, because these gases and Particles are heavier to air. But also the escape This pollutant is harmful to the environment, which is well known contributes to climate change.

Lane boundaries as they are for example in the DE 299 17 732 U1 . DE 297 05 037 U1 . DE 202 10 970 U1 or EP 0 505 373 B1 are described in the form of a full concrete body, the highest safety class against impact for all vehicle classes. However, such delimitations hermetically shield the roadway in the ground area. This has the disadvantage that on the one hand, the surface water can not drain and on the other hand can form extensive water surfaces on the road, which can cause traffic and dangerous situations especially in large rainfall.

Of Furthermore, the exhaust gases, which are heavier than air, can do not escape.

Noise barriers made of steel or other materials must be impermeable to air so that they can fulfill their function. They thus strengthen in combination with the edge boundaries only the concentration of pollutants in the ground area of the roadway. In addition, these soundproof walls have no sufficient safety class against impact, because steel limitations limited are able to absorb high impact forces. Furthermore The edges of these boundaries also create danger spots for Car and motorcyclist.
