Accessible Path of Travel

Accessible paths of travel shall present the following characteristics:

 

1. The width of the path free of obstacles should be enough to allow all pedestrians foreseen in all directions; considering 1000 mm per each simultaneous pedestrian. It shall be always more than 2000mm and no one obstacle can reduce it to less than 1200mm.

2. The accessible path shall be linear and continued, while avoiding direction changes between pedestrian crossings.

3. All intersections shall be clearly visible and defined with safety and traffic control elements such as signs or lights. Pedestrian crossings shall be clearly distinguished from the road with contrasted colour marks.

4. In pedestrian crossings, when there is a height change, curb cuts shall be provided following the requirements of section 

5. The maximum permitted gradient for a running slope in accessible paths is 5%.

6. The clear headroom along the entire path shall be at least 2200mm.

7. Uneven surfaces in accessible paths should be avoided and the maximum height of
any irregularity shall be 5mm.

8. The accessible path shall not have dangerous unprotected level changes. Unevenness, gaps and openings with a height difference greater than 500 mm should have guardrails.

9. Accessible paths shall be free of protruding objects like vegetation,  furniture and signs.

10. Accessible elements such as paths, crossing, stairs, etc., shall have a luminance of at least 100 lux. All lighting changes along an accessible path shall be gradual to prevent glare.

11.Drain grids shall never be within the accessible path or the accessible pedestrian crossing.

12.In outdoor areas, accessible paths shall be free of obstacles and located between the buildings facade and the furniture zone adjacent to the curb.

13.Parking entrances shall not modify the slope or the width of the accessible path.

14.The curb height shall be between 100mm and 150mm.

15.Utility covers should be avoided in accessible walking paths. When placing utility covers out of the accessible path is impossible, the maximum height difference shall be 5mm. When placing drain grids out of the accessible path is impossible, the maximum dimensions of the holes shall be 15 mm.

16. Standing water should be avoided with a cross slope up to 2%.

17.If there is a pedestrian bridge along an accessible path of travel it shall provide a ramp or an elevator and shall be shaded.

 

Interaction space
The interaction space is the space required by a person to interact with another person, furniture, appliance, machine or another element.

 

This space is also used by a person to transfer from a wheelchair to a seat or a toilet or to park a pram.

The interaction space shall not invade the accessible path. The interaction space can
be frontal or lateral.

 

The interaction space dimensions are 865 mm x 1420 mm.

 

When objects protrude into the interaction space, like shoes in a praying room entrance, paper bin in the toilet’s lateral approach space, or other similar cases, the interaction space can be marked with a carpet or painting with international symbol of disability. 

 

Protruding objects
Objects shall not protrude into the pedestrian path more than 100 mm.

In case of elements protruding more than 100 mm from façades, posts or other
elements, the protruding edge shall extend to the floor or be at least 300 mm above the floor.

Glossary of Terms

Tactile pavements are textured surfaces with contrasted colour that are perceptible and identifiable by feel or cane or residual functional vision that warns or informs people with visual disabilities.

Truncated domes in a grid pattern to provide a tactile surface under feet of blind users. They are used as a used as a warning of upcoming level changes or obstacles on the course of travel.

Flat topped elongated bars in the paving surface under feet of blind people. They are used as a directional sign to assist the independent mobility of people with visual disabilities.

Pendulum test value (PTV) is a measurement of the slip resistance of a floor surface, either an external or internal floor of a building. The least slip resistance a surface material is, the more likely people may skid or trip, especially in wet conditions. In average circumstances, slip-resistance is as follows:

0-18 = very low slip-resistance.

18-25 = moderate slip-resistance.

25-36 = good slip resistance.

Light Reflectance Value (LRV) is a numeric scale that is used to identify how much light a colour reflects or absorbs. It is used in universal design to identify the contrast between two colours. This can help to determine if there is sufficient contrast to visually identify a feature such as a fonts on a sign, elevator call button, a handrail and other items which need to be seen by visually impaired people.

The interaction space is the space required by a person to interact with another person, furniture, appliance, machine or another element.
