Information that explains truncated domes is good to know as it demystifies a mystery for many people. This design has been determined to be an efficient surface warning method. The design has been explicitly mandated by the Americans With Disabilities Act that was a federal law approved in 1990. The intended goal of this pattern is to provide unknowing pedestrians of a specific physical indication of their exposure to an upcoming potential hazard.
People have become familiar to seeing this visual signal in certain locations. They remain unaware the signal is not intended for the usual pedestrian; but is instead intended for the vision impaired members of their community. Most members of the public remain unaware why the ground surface changes in some locations.
The use of this particular type of detectable warning of an oncoming safety hazard is required by ADA Access Guidelines. The design of what is known as truncated domes is the only method permitted under the ADAAG. Many examples already exist in locations across the country. But, room for improvement still exists. New developments certainly need to comply with the mandated requirement. For building owners, developers, and ordinary citizens, it is constructive to know the reason behind this requirement that has been federally mandated.
This type of tactile warning system is making our environment safer for our most vulnerable citizens, for whom it is intended. Although, it is placed in many locations, few people are consciously aware of the reasoning behind it. A tactile warning system is used in many countries and is not limited to this country alone. It is known by different names. No matter what term is used, it means to describe is a textured ground surface indicator to help guide vision impaired and blind pedestrians.
The source of origin of this helpful device is Japan. It was first applied there from the late 1960s and onwards. This use in Japan was emulated by other nations. In the United States, the advantages of this approach were appreciated decades after others. The first application in Japan was tested in 1967, two years after its discovery. Thereafter, a national movement was inspired. Subsequently, applications could be seen by visitors to other countries.
In Japan, textured surface indicator warnings are found throughout the country. The United States followed others who placed surface warning indicators on crosswalks and other pathways of potential risk. Besides Japan, the United Kingdom and Australia were among others who preceded the United States in the use of such a warning mechanism.
Truncated domes is one expression by which this technique is known. The term describes the physical appearance of the design. Its miniature dome pattern is both obtrusive enough for its specific pedestrian targets and yet not excessively obtrusive for other pedestrians. Research has demonstrated that design regularity is necessary for effectiveness. Research has also indicated that this special miniature dome pattern is the only example which has repeatedly confirmed its value.
