Mitträcken

Mitträcken, also known as central barriers or median barriers, are safety structures installed on the dividing strip (median) of roads. Their primary purpose is to prevent vehicles from crossing into oncoming traffic, thereby reducing the severity and number of head-on collisions, which are often the most fatal type of crash.

These barriers are typically constructed from concrete, steel, or a combination of materials. Concrete barriers, often seen in a Jersey barrier profile, are robust and effective at redirecting errant vehicles. Steel barriers, such as guardrails or cable barriers, can also be used. Cable barriers, consisting of tensioned steel cables, are designed to absorb impact energy and return to their original position, minimizing damage to the vehicle and the barrier itself.

The design and placement of mitträcken are crucial. They are installed on roads with a history of cross-median accidents or on highways where traffic speeds are high and the potential for severe accidents is significant. Factors like median width, traffic volume, and speed limits influence the type of barrier chosen and its specifications. The effectiveness of mitträcken is well-documented in traffic safety studies, which show a substantial reduction in fatalities and serious injuries where they are implemented. Regular inspection and maintenance are essential to ensure their continued effectiveness.
