General Design Standards
Unlock Audio Lesson
Let's start by discussing the general design standards for escalators. Can anyone tell me how wide the steps of an escalator should be?
Is it 1200 mm?
Close! The minimum step width should be 1000 mm, but it is preferable to have 1200 mm to enhance safety and user comfort. Why do you think step width is important?
It’s probably because more width gives more space for people to stand and hold on.
Exactly! And in terms of inclination, escalators should have an angle of 30 degrees, with a maximum of 35 degrees. This keeps them manageable for most users. Remember the acronym 'WIS' for Width, Inclination, Speed when considering these principles. What’s the maximum speed for escalators?
Not more than 0.5 m/s?
Correct! Keeping the speed down helps in preventing accidents. To recap, we discussed the step width and inclination of escalators, and their maximum speed.
Safety Features

Now, let’s move on to safety features. Why do you think we need emergency stop buttons at landings?
In case something goes wrong, it will help to stop the escalator immediately.
Exactly, it's a critical safety feature! Additionally, we should have contrasting colors for step demarcation to enhance visibility. Can anyone think of other safety features?
Lighting! It’s important to have good lighting at landings.
Yes, well done! Proper lighting helps users, especially those with visual impairments. To help us remember, let's think of the acronym ‘LADS’ - Lighting, Awareness (with warning signs), Demarcation, and Safety buttons. Could someone summarize what we've learned about the safety features?
We learned that escalators need emergency stop buttons, good lighting, and step color contrast.
Great summary!
Accessibility Enhancements
Unlock Audio Lesson
Today, let’s explore accessibility enhancements for escalators. What do you think are some features we can add to make escalators easier to use, especially for people with disabilities?
Maybe tactile indicators and voice alerts?
Absolutely! Tactile ground surface indicators near landings alert users about escalators. Voice alerts can indicate directions or caution. What’s something that can help those who might not see the escalator clearly?
Warning signs about using escalators?
Exactly! That’s a vital point. Let's remember the acronym 'TAG' for Tactile indicators, Audio alerts, and Guidelines. Let’s recap what we discussed about accessibility enhancements.
Tactile indicators, voice alerts, and warning signs are important accessibility features for escalators.
Perfect recap!
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
It outlines general design standards, safety features, and accessibility enhancements for escalators and moving walks. Although not recommended for people with disabilities, guidelines are proposed to improve usability for the wider public.
Detailed
In modern architecture, escalators and moving walks serve as essential components of vertical transportation systems, allowing efficient movement between different floors. This section provides detailed design standards, including specifications for step width, inclination, and speed, ensuring the safety of users. Additionally, various safety features such as emergency stop buttons and anti-slip surfaces are highlighted. Despite the challenges faced by persons with disabilities in using escalators, the section underscores the importance of incorporating universal design principles to make these systems more usable for everyone. Accessibility enhancements, such as tactile ground surface indicators, warning signs, and voice alerts, are discussed to improve user experience and safety.

• Step width: Minimum 1000 mm (preferably 1200 mm)
• Inclination: Typically 30 degrees, never more than 35 degrees
• Speed: Not more than 0.5 m/s
• Step riser height: Uniform, max 220 mm
• Must include handrails on both sides, moving in sync with steps
Detailed Explanation
This chunk outlines the general design standards for escalators. The step width should be a minimum of 1000 mm, which is ideal for usability, but ideally should be 1200 mm for better comfort. The inclination of the escalator should be around 30 degrees; however, it should never exceed 35 degrees to ensure safety and ease of use. The speed of the escalator is capped at 0.5 meters per second to prevent accidents and allow users to step on and off safely. The step riser height should be uniform, with a maximum height of 220 mm to avoid missteps. Finally, it is essential that handrails are included on both sides of the escalator, and they should move in sync with the steps so users can hold on securely as they ascend or descend.
Examples & Analogies
Imagine walking up a set of stairs that is always just a bit too steep or narrow. It would be uncomfortable and potentially dangerous, right? That’s why escalators have specific design requirements; they help everyone feel safe and steady, just like a carefully designed staircase that allows you to also hold onto a railing as you go up.

• Emergency stop buttons at both landings
• Skirt panel safety devices
• Step demarcation in contrasting colors
• Adequate lighting at landings
• Anti-slip tread surface
Detailed Explanation
This chunk addresses safety features that are crucial for escalators. Emergency stop buttons must be located at both the top and bottom landings, which allows users to quickly halt the escalator if something goes wrong. Skirt panel safety devices help prevent users from getting caught in moving parts. The steps should have contrasting colors, making it easier for users, especially those with visual impairments, to see where to step. Proper lighting is also necessary at landings to ensure people can see as they enter or exit. Finally, the tread on the steps must be anti-slip to provide adequate grip and prevent slips and falls.
Examples & Analogies
Think of an escalator like a moving sidewalk in the airport. Wouldn’t you want it to stop if someone fell or a bag got caught? That’s why there are emergency stop buttons. Plus, if the edges are a different color, you can clearly see where to step, just like brightly colored curbs that help you see where to walk on the street.

• Tactile ground surface indicators (TGSIs) near landings
• Warning signs about escalator usage
• Voice alerts and visual displays for direction and caution
Detailed Explanation
This chunk discusses enhancements made to escalators to improve accessibility. Tactile ground surface indicators (TGSIs) guide individuals with visual impairments to the escalator entrance, making it easier for them to navigate. Additionally, clear warning signs regarding using the escalator ensure that all users are adequately informed about its safe operation. Furthermore, escalators may include voice alerts and visual displays that signal direction and caution, which can be highly beneficial for people with hearing or visual disabilities.
Examples & Analogies
Imagine walking blindly towards an escalator. How would you know when to stop or where to step? TGSIs act like a guide that informs you of what’s ahead, similar to how you might follow a trail of footsteps in a sandy beach to find your way back to your towel.
