The estimated number of people visually impaired in the world is 285 million, 39 million blind and 246 million having low vision
65 % of people visually impaired and 82% of all blind are 50 years and older (Table 2).
The distribution of people visually impaired in the six WHO Regions is shown in(Table 3) with the percentage of the global
impairment shown in parentheses. Figure 1 shows the number of people visually impaired, with low vision and blind per million populations in the six WHO
Regions and in India and China separately.
- An estimated 253 million people live with vision impairment: 36 million are blind and 217 million have moderate to severe vision impairment.
- 81% of people who are blind or have moderate or severe vision impairment are aged 50 years and above
Government of India is also Following Internationally Standard Design for Visually Impaired People. Like National Building Code 2016 VOLUME 2. As per National Building Act we make Blind people to Visually Impaired Friendly.
Blind people is also learning in Education when they Walk Strait and when they want to take turn and When Exit and When Entrance. Ref. by : Australian Tactile Indicators Standards
Warning TGSIs should be used to warn of hazards such as the following
1)Life threatening hazards where serious falls may occur, such as at railway platforms or wharves.
2)Overhead hazards that protrude into the continuous accessible path of travel, such as the underside of a staircase that is unprotected. Wherever possible an architectural treatment should be used, e.g., the installation of a railing, seating or railing.
3)Suspended hazards that protrude into a continuous accessible path of travel, such as a telephone booth, drinking fountain, fire hose reel or the like. Such hazards should be installed out of the continuous accessible path of travel.
4)Vehicle hazards on roadways that are not separated from pedestrian access ways by a change of grade, such as vehicular driveways that intersect with clear continuous accessible paths of travel from large vehicular precincts, where a motorist’s vision is limited, e.g., exits from car parks.
Directional tactile ground surface indicators should be used—
1)Mid-block crossings to indicate the position of crossings, bus or tram stops.
2)Intersections that incorporate slip lane crossings to indicate the position of the crossing and the direction of travel across the island where the path of travel has not been cut through the island.
3)Intersections where the point of entry to the road is more that 3000 mm from the property line and
4)Across an open space from point A to point B, where there are no other tactual cues.
Every Blind people can go everywhere and its big help of TGSI and its Real Freedom of Visually Impaired peoples.
It’s many benefits for a Visually Impaired Tourist and Country. No need of Friend or House member because of Tactile Indicators was installed and they can easily go for anywhere.
In this countries Australia, New Zealand, Singapore, Canada and European Unions are already using TGSI (Tactile Ground Surface Indicators) in Railway Station, Airport, Subway Station, Garden, Corporate offices and Shopping Mall. That countries blind people go everywhere without help of any people. TGSI is the best friend of Visually Impaired peoples.
