Feeling safe, walking and wheeling

If we want to get everyone walking and wheeling for their health, and the health of the environment, a few things have to change. If people don’t feel safe on our streets, they will avoid the journey or take the car. Many people who are blind or have low vision fear a collision with vehicles and cyclists. That makes them feel unsafe on our streets, and means they are less likely to venture from well-known routes in their community.

Pedestrians who are blind or have low vision have difficulty knowing when it is safe to cross at non-signalised crossing points. This is compounded by traffic volume and speed. Not every person with low vision uses a cane or dog indicating to drivers they have reduced vision.

Two young women stand at a pedestrian crossing. One is holding the arm of the other. There is a car in the background on the crossing. Are they feeling safe walking and wheeling?

If you want to know more about the issues encountered by people who are blind or have low vision, take a look at the study by Victoria Walks. They conducted a survey of people with vision impairment and carried out some street audits. The aim was to gain a better understanding of the road and footpath safety issues encountered by this group.

“Difficulty in judging whether it is safe to cross the road” was the biggest overall concern, followed by tripping hazards on the footpath. Crossing the road at non-signalised intersections was not an option for many. Given that most mid-block crossings and intersections are not signalised, this severely limits this group’s mobility. But they are not the only ones. People with poor depth perception and some cognitive conditions find it difficult to judge when to cross.

Interaction with other road users

Drivers are required to give way to pedestrians. However, at traffic lights for example, motorists failing to give way was the biggest concern for people who are blind or have low vision. Failing to give way to pedestrians on the footpath across driveways was another real problem. Shared paths with cyclists, pedestrians with dogs, and just other pedestrians were also an issue.

People who are blind or have low vision are not the only ones with poor road and footpath experiences. Consequently, if we can get it right for this group, every pedestrian should benefit.

Site audit issues

Issues common to most areas audited were:
– Tripping hazards and obstructions on the footpath such as low hanging tree branches, shop sandwich boards, and outdoor dining.
– Poor kerb ramp design that potentially sends pedestrians with a vision impairment into the middle of an intersection rather than directly across the road.
– Differences between the width of a crossing and the width of the kerb ramp used to access it causing a potential trip hazard.
– Missing or poorly functioning Tactile Ground Surface Indicators (TGSI) or audio tactiles.

The title of the report is Road Safety for Pedestrians who are Blind or Have Low Vision. There is more detail about each audit location in Victoria and what was recommended. Also more detail from the survey, all of which is instructive.

What happens when tactiles fail

Taking another perspective, Dean Homicki has some short videos explaining the details that matter and why. His latest video is the placement of tactiles at a railway crossing. He titled it, “Why the chicken shouldn’t, couldn’t and didn’t cross the rail-road“.

It’s not the bus that’s inaccessible

Imagine you could travel to only 1% of the city where you live – areas that were easily accessible to other residents. The main problem is it’s not the bus system itself that’s inaccessible. It’s all the infrastructure around it such as footpaths and kerb ramps. That’s the claim by researchers in Columbus, Ohio.

“People with mobility disabilities need to get to and from bus stops to use public transportation, and that isn’t easy in many parts of the city.”

The roadway is marked with the words "bus stop" in yellow lettering.

The study of wheelchair users who rely on public transport, found that powered wheelchair users were a little better off than manual users. The researchers used high-resolution, real-time data on the usage of buses by people with and without disabilities.

In one analysis, the researchers found how many of the bus stops could get users to various places in the city within 30 minutes. Manual wheelchair users had 75% fewer bus stops they could use compared with non-disabled users. For powered wheelchair users, they experienced 59% fewer stops. Even when they gave them more time to complete the journey, it was little better. That means wheelchair users are confined to self-segregated parts of the city.

Public transit is not a business, it is not just a social service.  It is crucial urban infrastructure and footpaths are part of that.

The research paper is titled, Disparities in public transit accessibility and usage by people with mobility disabilities. You will need institutional access for a free read.

Abstract

Many people with mobility disabilities (PwMD) rely on public transit to access crucial resources and maintain social interactions. However, they face higher barriers to accessing and using public transit, leading to disparities between people with and without mobility disabilities.

In this paper, we use high-resolution public transit real-time vehicle data, passenger count data, and paratransit usage data from 2018 to 2021 to estimate and compare transit accessibility and usage of people with and without mobility disabilities. We find large disparities in powered and manual wheelchair users’ accessibility relative to people without disabilities.

The city center has the highest accessibility and ridership, as well as the highest disparities in accessibility. Our scenario analysis illustrates the impacts of sidewalks on accessibility disparities among the different groups. We also find that PwMD using fixed-route service are more sensitive to weather conditions and tend to ride transit in the middle of the day rather than during peak hours.

Further, the spatial pattern of bus stop usage by PwMD is different than people without disabilities, suggesting their destination choices can be driven by access concerns. During the COVID-19 pandemic, accessibility disparities increased in 2020, and PwMD disproportionately avoided public transit during 2020, but used it disproportionately more during 2021 compared to riders without disabilities.

This paper is the first to examine PwMD’s transit experience with large high-resolution datasets and holistic analysis incorporating both accessibility and usage. The results fill in these imperative scientific gaps and provide valuable insights for future transit planning.

A toilet on every high street

The economic value of public toilet facilities is often overlooked. We all have to go sometime and some of us sooner and more quickly than others. The availability of clean public toilets can make or break a shopping trip or social outing. People with bladder problems will restrict their movements to where they know the toilets are.

The Helen Hamlyn Centre for Design had a good look at this issue. Their report outlines how they went about finding an alternative model for high street toilets. The project was titled, Engaged: a toilet on every high street.

This design research project was about a simple concept of reusing vacant high street units as toilets (plus commercial or community space). It explored the idea before thinking about how to implement it.

The research explored how this idea would fit into current systems and infrastructure. People within retail, community safety, government and urban design were consulted. Then they spoke with council officers to see how they could make it happen.

Pub staff responsible for toilets talked about the problems with toilets. Public toilet provision is complex. A lot can go wrong. The aim therefore was to understand what the public want, what councils can achieve and where the pitfalls are.

The key areas or outcomes for Engaged were the issues of:

  • Closed and Temporary Toilets
  • Future Inclusive Toilets
  • Lootopia and the High Street
  • Toilets in the 24-hour City
  • Talk Toilets

The report explains these dot points in greater detail using case studies, and accessible toilets are included in the discussions as well as criminal behaviour.

Everyone needs a toilet

Everyone needs to use the toilet, and people shouldn’t be ‘designed out’. People who spend all day outside, such as rough-sleepers, rely more on public toilets than most. Yet privately-owned, publicly-accessible toilets may not be accessible to them, either from exclusion or from feeling that they would be permitted. Other groups who may feel excluded include teenagers and people of colour. Discrimination that associates groups with anti-social or criminal behaviour reduces the number of toilets that people can access.

The researchers found their findings match similar surveys by the Bathroom Manufacturers Association, and AgeUK London. ‘High streets’ was the main location where respondents thought public toilets were not good enough (70%), ahead of parks (47%). This data is useful for showing the value that public toilets bring to the high street. If people leave early due to a lack of toilets, that will hurt businesses and the wider community, as well as limiting people’s participation and quality of life.

The title of the report is, Engaged: a toilet on every high street. The Helen Hamlyn Centre for Design did the research published by the Royal College of Art. It is a good example of talking to stakeholders before even thinking about solutions.

Everybody poops

A Canadian briefing paper, Everybody Poops: Public toilets are a community issue, covers similar ground. Although these facilities are an important part of the community, local authorities are not keen to provide them. Solutions are around advocacy and partnerships. The paper has a link to The Safer Bathroom Toolkit, which has a focus on people who use substances.

Overcoming bias in AI

Artificial Intelligence (AI) is entering our everyday lives with increased speed and sometimes without our knowledge. But it is only as good as the data it is fed, and the worry about bias is a concern for marginalised groups. AI has the potential to enhance life for everyone, but that requires overcoming bias in AI development. In his article, Christopher Land argues for more advocacy and transparency in AI.

The power of machine learning comes from pattern recognition within vast quantities of data. Using statistics, AI reveals new patterns and associations that human developers might miss or lack the processing power to uncover.

Designing for the average is fraught with problems. Statistical averages do not translate to some kind of human average. That’s because statistics don’t measure human diversity. That’s why AI processes are at risk of leaving some people behind. But in gathering useful data there are some privacy issues.

AI shows great promise with robot assistants to assist people with disability and older people with everyday tasks. AI imaging and recognition tools help nonvisual users understand video and pictures.

Christopher Land outlines how AI and machine learning work and how bias is introduced into AI systems if not prevented. He also has some recommendations on strengthening legal protections for people with disability. The paper is not technical. Rather it explains clearly how it works, where it’s used, and what needs to be done.

The title of the article is, Disability Bias & New Frontiers in Artificial Intelligence. The “Black Box” issue is explained and the need for a “Glass Box” is presented.

From the abstract

Bias in artificial intelligence (AI) systems can cause discrimination against marginalized groups, including people with disabilities. This discrimination is most often unintentional and due to a lack of training and awareness of how to build inclusive systems.

This paper has two main objectives: 1) provide an overview of AI systems and machine learning, including disability bias, for accessibility professionals and related non-development roles; and 2) discuss methods for building accessible AI systems inclusively to mitigate bias.

Worldwide progress on establishing legal protection against AI bias is provided, with recommendations on strengthening laws to protect people with disabilities from discrimination by AI systems. When built accessibly, AI systems can promote fairness and enhance the lives of everyone, in unprecedented ways.

Diversity and inclusion in AI

An Australian book chapter takes a comprehensive and practical approach to how equity and inclusion should be considered throughout development. This should be done at both governance and development levels by applying inclusive design and human-centred design to the AI ‘ecosystem’.

The title of the chapter is Diversity and Inclusion in Artificial Intelligence.

Design guide for active travel

This design guide aims to improve infrastructure for people wanting to walk, cycle, scoot, and ride mobility devices. That means anyone and everyone who is not a driver of a motor vehicle. This is part of the ACT Government’s policy is to support active travel.

In the Canberra context, unless designated, all paths are shared by people walking, wheeling, cycling and using mobility aids.

Few people fully understand road rules, which is why design treatments must indicate that pedestrians have priority.

People using mobility devices and older people are given the label of “vulnerable” pedestrians. This is default language in transport jargon, but serves, unfortunately, to reinforce stereotypes. In reality, all pedestrians are vulnerable compared to motor vehicles.

When all pedestrians are incorporated into designs, we should just talk about “pedestrians walking and wheeling”. And with a Safe Systems Approach there should be no delineation between who is safer than whom.

Movement and Place framework

The Movement and Place framework together with a Safe Systems approach puts people into the centre of the frame. The lens has always been on vehicle traffic flows and the convenience and economics of reducing traffic delays. If we are to have active travel really happening, we have to re-think this priority.

The Design Guide is comprehensive and serves as a “how-to” tool for transport planners. It covers:

  • principles of safe design
  • street types
  • walking
  • cycling and micromobility
  • intersection principles and elements
  • signalisation
  • pedestrian and cycling provision at intersections
  • public transport
  • intersection guidance

Bathroom aesthetics and accessibility

A touch of universal design thinking has entered the design of bathroom design and fittings. Research from many quarters has established that people want to stay home in their later years. Consequently designers need to get on board with designs that are functional and look good too. A whitepaper from Nero Tapware updates designers on bathroom aesthetics and accessibility.

“Accessible living spaces are becoming increasingly important as the majority of Australians, both with and without disabilities, have a desire to stay in their current homes rather than enter residential aged care.”

The Nero whitepaper discusses the many aspects of design in the context of the new Livable Housing Design Standard in the National Construction Code. However, their bathroom layout and overall style is similar to the public bathroom design. A universal design approach would use the space creatively and leave out grab rails until, or unless they were needed. That’s because grab rails placement needs to fit the individual user’s requirements.

“By modifications to our built environment, architects and designers can promote usability, participation in activities, and enable older users to live comfortably and independently.”

It is good to see product designers preparing to align with the new Livable Housing Design Standard. However, the photographs in the whitepaper do not align with the universal design concept of the Standard. That is, each picture shows grab rails which are not part of the Standard. However, reinforcement in the walls is required so that grab rails can be added later at any placement the user needs.

Aesthetics impact wellbeing

The whitepaper nicely spells out all the issues including the importance of wellbeing. It notes that a liveable home must be multifunctional and it must feel like home. Lack of colour matching and styling options can end up looking clinical. The whitepaper argues that end users feel undervalued, neglected and uncared for.

The whitepaper is titled Aesthetics, Accessibility & Ageing: Designing Livable Spaces Without Compromising Function or Style. It was published in Architecture and Design. The full 58 page Mecca Care product catalogue has great pictures and a section on assistive living.

The Mecca range is specifically for people who require assistive living designs. While the photographs show nicely designed bathrooms, grab rails take the look and feel away from a “conventional” bathroom. But if these fixtures and fittings keep you at home for longer then at least they can look good. Wall hung toilet pans, however, are a good idea for any home.

Universal in-wall bodies

A companion Nero whitepaper is A Universal Approach to Bathroom Installation. The in-wall body is an installation that separates the in-wall body from the trim kit – the visible bits. In-wall bodies allow builders and customers to select the right fittings after tilers have finished. Customers can delay their design decision informed by the latest trends. At a later date home owners can update their fittings without affecting walls and tiles.

Thinking of wheelchair users…

Lifemark in New Zealand has a handy little brochure that sets out bathroom dimensions and placement of fittings for wheelchair users. They use the term universal design because the features can be used by most people. However, they do look as if they are specifically designed for wheelchair users. And there is no need to make this look like a hospital.

Designers can still be creative and provide style with colour and attractive fittings. One thing the brochure does not mention is colour contrast for people with low vision. Contrast between the floor and the wall is important, and for some, contrasting fittings work well.

The title of the brochure is Universally Designed Bathrooms. Of course, the bathroom is only one element in a home that needs to be accessible for a wheelchair user.

Accessibility at neighbourhood scale

There are many tools for measuring environmental sustainability features in the built environment. But measuring access for all, is based on legislation and cost rather than user-based. Indeed, building standards for disability access have filled this knowledge gap but in the process, held back learning at the same time. That’s because you learn how to complete checklists but you don’t gain understanding of the issues this way. This is one reason that architect Mary Ann Jackson says built environment practitioners do not understand disability.

Neighbourhood scale accessibility measurement tools show how improvements can be determined in a planned way rather than ad hoc reactions.

A Melbourne street scene showing pedestrians and a tram.

Built environment knowledge and the lived experience of people with disability need connection. We need a tool that measures the overall accessibility of the built environment by incorporating the lived experiences of people with disability.

Increasingly, assessment of the built environment is becoming interdiciplinary. However, despite all the many built environment performance tools, input from people with disability are often left out of the equation. The move to co-design methods for new work is helpful, but does little to deal with existing built environments.

The title of Jackson’s 2019 article is, Accessing the Neighbourhood: Built Environment Performance for People with Disability. It explains the rationale behind the the development of the Universal Mobility Index. The key aim is to address the fragmented nature of current access across all areas of the built environment.

From the abstract

The existing built environment still fails to meet the needs of people with disability. This is despite rapid urbanisation, population ageing, failing infrastructure, and evidence that the built environment affects health and well-being,

In a parallel universe, improving built environment ‘sustainability’ performance, via measurement, receives much attention. Analysing the built environment at micro-scale (buildings), meso-scale (neighbourhood) and macro-scale (city-wide) is undertaken from various multidisciplinary perspectives.

Built environment performance is measured in many ways, but accessibility performance for people with disability, at neighbourhood scale, is rarely considered.

People with disability continue to experience lack of meaningful involvement in research, participation in decision-making, partnership equality, and direct influence over policy, with the built environment arena increasingly becoming a private-sector activity.

The actors involved, however, have little understanding of either the accessibility needs of people with disability, or the inaccessibility, particularly at neighbourhood scale, of the existing built environment.

This paper explores the design, planning and politics of an inaccessible built environment. Assessing the accessibility of the built environment for people with disability, at neighbourhood scale, is an essential component in the process of built environment accessibility improvement. As a result of collaboration between the domains of the built environment and disability, a new tool, Universal Mobility Index, has emerged and is undergoing further development.

Access Audit Handbook

The Royal Institute of British Architects has updated their Access Audit Handbook in conjunction with the Centre for Accessible Environments. Access auditing is an evolving concept and means different things to different people. Some take it as being compliant with a standard while others consider aspects beyond compliance.

The Access Audit Handbook is priced at £40.00 from either the Centre for Accessible Environments or the Royal Institute of British Architects.

Fortunately, the Ergonomics in Design for All Newsletter explains the content of the document. In doing so, the newsletter provides an synopsis of some of the key concepts in the handbook.

Front cover of the access audit handbook.

Similarly to Australian Standards, British Standards only apply to people with disability and do not cover any other groups in terms of access and inclusion. This is despite other groups who fall under anti-discrimination law. The handbook addresses some of these gaps. For example:

Faith spaces, prayer facilities, features relating to women’s safety and their well-being, including pregnancy and menopause, baby feeding and changing, and non-gendered sanitary and changing facilities.

A woman cradles a new baby in her arms. They are both white skinned.

There is guidance on neurodiversity and reducing sensory overload, anxiety and stress, such as quiet rooms. Designers are asked to plan logical wayfinding with straight lines, and create curves rather than corners.

Technology is evolving on building accessibility, space and wayfinding, and auditors need to keep up with these developments. Lift destination control systems are a case in point where people no longer press a button for their floor. The central control system can be very confusing where there is a bank of lifts.

Case studies

The handbook recommends engaging with building users for insights into the level of accessibility and to keep them engaged throughout the project. There are six case studies: a theatre, a zoo, a parish church, a university science lab, and an outdoor space. The case study of an inaccessible heritage town hall shows how to create an accessible community building.

The handbook has 32 checklists for the external environment, internal building space, management and communication.

Older people, ageism and digital design

Do stereotypes of older people affect how digital technology is designed? A team of researchers found that ageism has the potential to influence design in negative ways. They found co-design partnerships overcame ageist attitudes and were more likely to produce digital technologies that are needed, wanted and used.

Ageism can have a detrimental role in how digital technologies are designed. Participating with older people in the design process has the additional benefit of countering stereotypes. Image shows a group of older people on a desert camping expedition.

Of a group of older people having fun together on a camping tour.

Older people said the “ultimate partnership” in co-designing is to be involved from the beginning through to the end of the design process. Sharing control over design decisions was an important part of the process. They are more than informants – they are equals who have valuable contributions.

The researchers noted that although this vision of co-design is shared by designers, it is not always the case in practice.

Image shows older people working together on a workshop question.

Older people sit at round tables discussing questions. There are four round tables shown in this picture.

Older people in the study also said that ageism emerges in implicit and explicit language about ageing. And ageist images can influence the design process. Consequently, the researchers say it is important to view the diversity of older people.

Co-design with older people

How and when to involve older people in digital design is also important. Understanding co-design with older people has the potential for avoiding insufficient prototyping, biases and errors in the design process.

The title of the article is, An “ultimate partnership”: Older persons’ perspectives on age-stereotypes and intergenerational interaction in co-designing digital technologies.

From the abstract

There is a gap between the ideal of involving older persons throughout the design process of digital technology, and actual practice.

Twenty-one older people participated in three focus groups. Participants experienced ageism in their daily lives and interactions with the designers during the design process. Negative images of ageing were pointed out as a potential influencing factor on design decisions. Nevertheless, positive experiences of inclusive design pointed out the importance of “partnership” in the design process.

The “ultimate partnership” in co-designing were where they were involved from the beginning, iteratively, in a participatory approach. Such processes were perceived as leading to successful design outcomes, which they would like to use, and reduced intergenerational tension.

Accessible fitout case study

The Centre for Accessible Environments in London has been providing access advice for many years, many of them heritage buildings. As a not-for-profit, their aim is for more mainstream buildings to be accessible and inclusive. They got the chance with the office space for the Royal College of Occupational Therapists (RCOT). The Centre for Accessible Environments (CAE) website has an overview of the work they did on this building.

The image shows the accessible shower room prior to the refit. The design is based on a public standard and looks very clinical.

The building accommodates around 90 staff across four floors with meeting rooms on the ground floor. This floor had level access, powered doors, and an accessible shower room that looked like a hospital room. Not what CAE would consider gold standard.

The image shows the same wheelchair accessible shower room but with improved colour aesthetics. While this might meet British Standards, Australian access consultants might take issue with some aspects. The placement of the mirror, for example.

The outcome of CAE’s involvement is that the fit-out of the shower room looked less clinical despite the considerable amount of specialised equipment and features. The overall success was the focus on detail such as the amount of pile in a rug.

Quiet spaces and soundproofing and height adjustable desks are also part of the fitout. CAE’s access consultant also acknowledge that flexibility of space is essential. “Until people use a building following a redesign, you don’t know if it’s going to meet the needs of everyone.
