2. Footpaths (Sidewalks)

• Minimum clear width should be 1800mm to accommodate two wheelchairs passing each other. • In constrained urban areas, 1200 mm is the minimum permissible, but passing spaces must be provided every 25–30 meters. • Clear headroom of 2100 mm is mandatory.

When designing footpaths or sidewalks, it's important to ensure that they are wide enough for people to move safely and comfortably. A minimum width of 1800 mm is recommended so that two wheelchairs can pass each other without difficulty. In busier areas where there may not be enough space, a narrower width of 1200 mm can be allowed, but there must be spots every 25 to 30 meters where pedestrians can step aside. Additionally, the height above the footpath must be clear, meaning that the space above must be at least 2100 mm high to prevent anyone from bumping their heads.

Imagine trying to walk through a narrow hallway with a friend where you want to pass each other. If the hallway is too narrow, one of you would have to squeeze against the wall, which can be uncomfortable and lead to accidents. Likewise, if a wheelchair user meets someone on the footpath, having enough space is crucial for both to pass easily.

• Surfaces must be firm, level, slip-resistant, and non-reflective. • Avoid materials that create glare or uneven surfaces (e.g., cobblestones). • Tactile Ground Surface Indicators (TGSIs) must be installed: – Warning tiles (e.g., truncated domes) at intersections. – Directional tiles to guide the visually impaired.

The surface of the footpath should be designed with safety in mind. It needs to be firm and level so that people can walk without tripping. It should also be slip-resistant, especially in wet conditions, and non-reflective to avoid glare from the sun or lights that could blind pedestrians. Moreover, certain tactile indicators, like warning tiles at intersections and directional tiles, are vital for guiding visually impaired individuals; these surfaces can be felt underfoot, offering guidance and alerts about changes in direction or upcoming hazards.

Think of the footpath surface like a good pair of shoes. Just as shoes need to have good grip to prevent slipping, footpaths need to be made from material that doesn’t get slippery when it rains. Tactile indicators act like a road map under our feet, helping someone with sight difficulties navigate safely, similar to how a guide dog helps a visually impaired person.

• Longitudinal gradient should not exceed 1:20 (5% slope). • Cross-fall (side slope) should be limited to 1:50 to avoid imbalance in wheelchairs.

The slope of a footpath, both in length and width, is essential for ensuring easy movement. A longitudinal gradient should not be steeper than 1:20, which means that for every 20 units of length of the footpath, it can rise only 1 unit. This equates to a 5% slope, which is a manageable incline for everyone, especially those using wheelchairs. The cross-fall—how sloped the path is from side to side—should be limited to 1:50 to keep wheelchairs stable and prevent them from tipping.

Picture trying to ride a bike up a steep hill. If the hill isn’t too steep, you can keep your balance easily; but if it’s too steep, you might fall over. The same goes for footpaths—the right slope makes it easier for everyone to walk or roll over without worrying about losing control.

• Street furniture (e.g., poles, benches, trees) should be placed outside the minimum clear path. • Any unavoidable obstacle should have a contrasting color base or be detectable by a cane. • Overhanging signs or tree branches must not encroach into head clearance.

In designing footpaths, it's crucial to keep the path clear of obstacles to ensure smooth movement. Street furniture such as benches, poles, and trees must not block the minimum clear path that pedestrians need. If an obstacle cannot be removed, it should be painted in a contrasting color, making it easily visible for all users, especially those who are visually impaired. Furthermore, overhead signs and branches should be high enough not to impede anyone walking beneath them.

Imagine walking through a park full of beautiful flowers and benches. If the benches are too close to the path, you might bump into them while walking—just like how people can get hurt if there are unexpected obstacles on footpaths. Ensuring that these objects are clearly marked is like putting up a warning sign in a busy playground that says, 'Watch out for swings!'
