Tactile paving

As for the Blind (sometimes called guidelines system ) is generally described as systems that enable blind and visually impaired people highly to move autonomously in a public space.

Usually it is today at Tactile Bodenleitssysteme, alternative term Tactile ground control systems, soil indicators allowing blind and profoundly visually impaired people to move by means of a pendulum or stick cane independently on public roads and in buildings.

International and regional differently designed Tactile ground control systems from optical and tactile contrasting soil indicators such as corrugated plates and studded panels or pavers are found as structural features of streets, squares, public transport stops, railway stations and public facilities with control systems. The aim of the equipment is the accessibility in public (road ) space.

Features

In general, for the blind consist of conducting strips and attention fields. Conducting strips provide leadership to key destinations, such as outputs and inputs, stairs, elevators, or over large areas, such as places that offer little guidance or help to avoid obstacles. Attention fields can have very different functions:

  • Abzweigefelder indicate branches or changes in direction.
  • Direction fields display directions, for example in case of road crossings.
  • Auffindestreifen indicate the beginning of a reactive control system or laterally located targets, such as bus stops or lifts.
  • Entry fields, select the entry, such as at bus stops.
  • Warning fields warn of obstacles.
  • Recovery blade limit accessible areas, such as on platforms.

Blind people can the conductive strip and attention fields palpate means of a cane and geared so. Also on blind control systems is one of the features of stair railings or elevators with labels in Braille or pyramid Scripture and the contrast marking of steps or platform edges. Objective of the investment of reactive control systems is to blind and visually consistent way chains to offer and to enable them to use the appropriate facilities. As soil indicators typically grooved or ribbed plates and studded panels are used, sometimes also other surfaces, such as diamonds. They consist mostly of concrete, sometimes made ​​of natural stone with milled surface sporadically rubber, metal or plastic ( then mostly indoors, such as train stations. )

Soil indicators with grooves and ridges

Grooved tiles with striking groove patterns have long been used in Germany and are therefore the most frequently used soil indicators. These plates are described in DIN 32984. The narrow grooves defined therein may be using today's stock tips but hardly differ from the surrounding surface. Therefore increasingly plates with wider grooves to be installed. Instead of cross-sections with sine wave structure, the plates get increasingly trapezoidal ribs. About the ambient level protruding ribs are also more palpable than recessed grooves. Grooved pavement is of course used in a v. conductive strip and direction fields. You are through shoe soles felt only at very wide intervals ribs. With the long stick on the other hand they offer a good guidance over long distances (eg, between a train station and a bus terminal ).

Soil indicators with knobs

Studded panels are used in various fields of attention. Knobs can be Paving feel for not only with the long stick, but mostly with the feet and are therefore particularly suitable for the warning. The knobs are made typically of spherical caps or truncated cones.

Sound Stone

The Sound Stone is a standard developed by Rail concrete floor indicator, high-strength concrete with cast-in modules as a sound body. It is used on public roads in stop areas, crossings or also for marking hazardous areas. The Sound Stone has become a highly visible and distinctive sound when over ponds with the long stick. Upon entering the bottom of this indicator is a clearly perceptible attention noise. The Sound Stone is subject to the utility model protection, built-in modules - mechanoakustische converters are patented worldwide.
