How to Lay Tactile Paving Indicator Studs and Tactile Indicator Strips
The pavement of tactile guide path is in the same way as that of sidewalk square tiles, keep in mind during construction:
1. Tactile indicators can be divided into two categoriesaccording to their functions and uses.
1) Travel Tactile Indicators: the strip-shaped indicator, each 5mm above the ground, create sensation in the cane and the soles of the feet, making it easy to guide the visually impaired to walk safely forward in a straight line.
2) Warning Tactile Indicators: shaped like dots. Each dot is 5 mm above the ground to create sensation in the cane and the soles of the feet to inform the visually impaired that there will be a change in the spatial environment of the route ahead.
2. Tactile indicators can bedivided into 3 categories by materials:
1) Concrete tactile indicator
2) Rubber and plastic tactile indicator
3) Other materials (stainless steel, PVC, etc.) tactile indicator
The color of the tactile indicators shall be in contrast to the color of the adjacent sidewalk pavement and shall be in harmony with the surrounding landscape, preferably a medium yellow color. The design requirements for blind sidewalks shall comply with the following.The location and orientation of the tactile indicators should facilitate safe walking and smooth access to barrier-free facilities for persons with visual disabilities.
Tactile indicators pavement should be continuous, should avoid trees, poles, cable, tree holes, manhole covers and other obstacles, and other facilities shall not be occupied tactile indicators alley.
Tactile indicator corridors should be located 250~600mm away from sidewalk walls, flower beds and green areas.
Tactile indicator travel aisle can be located 250 ~ 600mm away from tree hole at the inside of the pavement; if there is no tree hole on the road, the travel aisle is located 250 ~ 600mm away from the standing edge. The stone should not be less than 500 mm
Tactile indicator travel lanes should have a warning tactile indicator at a turn, the length of which should be greater than the width of the tactile indicator travel lanes.
The bus stop along the sidewalk and the divider shall be equipped with a warning tactile indicator, the width of which shall be 300-600mm, and the distance from the curb edge shall be 250-500 mm.
A tactile indicator alley should be set up at a distance of 250-600mm from the steps, ramps and obstacles on the sidewalk.
A warning tactile indicator path should be set up about 250~600mm away from the pedestrian crossing entrance, square entrance, railway station entrance, etc. The length shall correspond to the width of each entrance.
When the sidewalk is in the shape of an arc, the direction of tactile indicator travel lane should be the same as that of the sidewalk.
The tactile indicator path into the pedestrian crossing line should be about 300mm away from the side stones, and it is advisable to pave a horizontal row of tactile indicator paths to indicate the entry of Range of pedestrian crossings. The tactile indicator pedestrian crossing should be laid in a perpendicular direction with the warning tactile indicator, and the width of the tactile indicator crossing should be 400~600mm.
A full-width barrier-free ramp is suitable for the corner intersection of the sidewalk. It is advisable to pave 1 row of ramp tactile indicators at the starting point of both sides of the ramp to indicate the range of the ramp, and 600mm is appropriate for the width of the tactile indicator paving. If abarrier-free street corner is formed at the intersection, it is advised to lay a row of tactile indicators on ramps in front of the corner stone ramp, to show that this is an access to the carriageway, pedestrian crosswalk range, and paved width is advised to be 600mm.
The tactile indicator should be set up at 300mm from the step at the location of upper and lower ends of tactile paving stairs and steps, the laying width of which should be 400mm~600mm. Two tactile indicators should also be laid at both ends in the middle rest platform, and the width should not be less than 300mm.
When a road pavement has a tactile indicator track, a tactile indicator shall be laid at the connection of bridge and road. The width of the pavement shall be the same as that of the road.
Bridges should be provided with tactile indicator corridors 400mm from the railings.
