Reduce speed – Our A-Team tips for practical trail building

Most user conflicts arise from excessive speed differences. Therefore, an important coexistence measure is to adjust the speed using technical means. We'll show you how!

Most user conflicts arise from excessive speed differences. When different road users are at eye level and traveling at similar speeds, significantly fewer conflicts arise. Therefore, an important coexistence measure is adjusting speed using technical means.
By the way, this does not mean that the driving pleasure is reduced.

VISUAL AXIS

The line of sight on trails determines reaction time when hikers and mountain bikers meet. While a wide view is ideal for spotting other users well in advance, changing direction is an important component. Long, straight trails encourage high speeds, and changing direction naturally slows down the pace.

INGROW

Overgrowth at eye level can be trimmed back as much as possible to allow other path users to see early. At ground level or on the path surface, however, it's acceptable to allow some overgrowth, provided the vegetation doesn't pose a danger of getting stuck. The rule of thumb is: the more overgrowth a path becomes, the more cautious users will be.

ROUGH PATH SURFACES

Rough trail surfaces with roots and stones should be preserved whenever possible. They not only offer plenty of variety but also reduce speed.

NARROW PATHS

As part of renovation and expansion projects, hiking trails are often widened and embanked. This creates wide, flat paths that allow more users to use the same area, but also allow for higher speeds. This increases the potential for conflict. Narrow, overgrown trail structures, on the other hand, slow down the pace.

ANCHOR STONES & STONE REINFORCEMENTS

Specifically placed rocks not only break the line of sight, but also intuitively lead to a slower pace. They can also "force" mountain bikers into a slight slalom course. However, they should not protrude too far into the path to avoid the risk of falls.
