Laying of Tactile Indicator Studs and Tactile Indicator Strips

The pavement of tactile path is in the same way as that of sidewalk square tiles, keep in mind during construction:

(1) When the tactile path is paved to the building, guide blocks shall be set up continuously in its direction of travel, and stopping stones shall be paved in front of the intersection block material. Pavement width shall not be less than 0.60m.

(2) The tactile block at the pedestrian crossing is 0.30m away from the edge stone or the stopping block is paved with one other pedestrian tile. Guide blocks are laid perpendicular to the stop blocks. The width of the pavement shall not be less than 0.60m.

(3) The bus stop shall be 0.30m away from the edge stone or paved with guide block every other pavement tile. Temporary stop sign is set up with stopping block, and the stopping block is paved perpendicular to the guiding block. The paving width shall not be less than 0.60m.

(4) The edge stone on the inside of the sidewalk is at least 0.10m above the sidewalk at the green belt, and the breaks in the green belt are connected with guide blocks.

Tactile path should be set in the following range:

  1. Downtown sidewalks on arterial and secondary roads, city and district commercial and pedestrian streets, and sidewalks around large public building lots.

  2. City plazas, bridges, tunnels and pedestrian crossings at three-dimensional intersections

  3. Pedestrian access to government office buildings and large public buildings

  4. Entrance lots to urban public green spaces

  5. Pedestrian bridges, entrances to pedestrian walkways, and accessible locations in the city's public green spaces should be equipped with blind corridors.

  6. Building entrances, service counters, stairs, accessible elevators, accessible toilets or toilets, bus stations, railway passenger stations, platforms of rail transit stations, etc. should be equipped with tactile indicators warning.

The classification of tactile path shall be in accordance with the following provisions:

1. Tactile indicators can be divided into two categories according to their function of use.

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 be divided into 3 categories by material:

1) Concrete tactile indicator

2) Rubber and plastic tactile indicator

3) Other materials (stainless steel, PVC, etc.) tactile indicator

Tactile indicators shall be sized in accordance with the following:

  1. 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.

  2. 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.

  3. Tactile indicator corridors should be located 250~600mm away from sidewalk walls, flower beds and green areas.

  4. 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

  5. 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.

  6. 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.

  7. A tactile indicator alley should be set up at a distance of 250-600mm from the steps, ramps and obstacles on the sidewalk.

  8. 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.

  9. 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.

  10. 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.

  11. The corner intersection of the sidewalk is suitable for a full-width barrier-free ramp. It is advisable to pave 1 row of left and right tactile indicator 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 a barrier-free ramp at the intersection forms a street corner, it is advisable to lay a blind guide path in front of the corner stone ramp to show access to the carriageway, pedestrian crosswalk range, and paved width can be 600mm.

  12. The tactile indicator should be set up at 300mm from the step at the location of  upper and lower ends of 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.

  13. 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.

  14. Bridges should be provided with tactile indicator corridors 400mm from the railings.
