Accessibility of public space

Infrastructure built before disability activists gained legal recognition of their human rights is often inaccessible. Newer buildings have basic access according to the standards imposed by governments. However, standards are no guarantee for full access for everyone. Consequently, urban researchers continue to write in the hope of effecting change for the accessibility of public space. A chapter in the book, Future of the City, is yet another offering about universal design and how accessibility is for everyone. This one includes a chart with solutions for typical barriers. These solutions are prescriptive with dimensions and measurements. The chart covers paths of travel, vertical travel, spatial elements and fittings, and transportation infrastructure. Photographs and good examples illustrate the points made. The information is useful for councils and capital works staff. It fits neatly with the Age Friendly Checklist for Councils. The title of the open access chapter is Accessibility of pubic space. Although there are some language differences in disability terms, the article is easy to read and makes some clear points. For example,

“For many people leading an independent life may be fully conditional on the accessibility of public spaces. Through accessible places, such people have a chance to participate in the social and economic life of the country or local society.”

“It is estimated that up to 30% of society have permanent or temporary limitations in mobility or perception. Many of these people do not have the status of a disabled person. Therefore, it can be said that accessibility concerns all of us.”

The chapter concludes with a comment about the gradual change in the accessibility of public buildings. However, there is more work to do.

Universal design and public libraries

Public libraries have more to offer than just books. Some people stay to read and browse, and others use meetings rooms for their community groups. The role of librarians is to help people to find what they are looking for. They are also keepers of local knowledge and services. People of all ages and backgrounds come and go. That means we are exposed to people with different values and interests. Potentially, that makes libraries a place to forge social inclusion. That’s where universal design comes in.

Gerd Berget’s writes on the theme of public libraries as places where diverse groups are visible to each other. She argues that public libraries have the potential for increasing respect for each other and thereby reducing social exclusion. In her paper, Berget proposes that the way to introduce more diversity into libraries is to take a universal design approach.

The paper begins with a history of disability and social justice. The role of public libraries as a physical space follows. The final part of the paper discusses the purpose of universal design and it’s role in social emancipation. Berget discusses the seven principles of universal design and how they apply to libraries in the final part of the paper.

The title the paper is, Universal Design as a Premise for making Public Libraries into Low-intensive Meeting Places. It’s a nicely written piece and good for newcomers to the field of universal design. It covers the philosophy, social issues of disability and the practicalities of universal design.

Berget concludes

“Although full inclusion is not yet achieved, public libraries have a great potential in increasing the social justice and reducing oppression. To achieve that, librarians need to be aware of and engaged in making (and keeping) the libraries into low-intensive meeting places. There is also a need for more user engagement in the design of the public libraries, both regarding buildings, collections and services. Finally, it is important to a preserve the public spaces that facilitate convivial encounters”.

Design guide for accessible public spaces

The Illustrated Technical Guide to the Accessibility Standard for the Design of Public Spaces published in 2014 by GAATES (Global Alliance on Accessible Technologies and Environments) is comprehensive. GAATES is based in Canada and refers to the Americans with Disabilities Act for standards, but they also include best practice features and design considerations. This means the design guide is applicable almost anywhere.

The guide is available as a Google Docs version or you can view it online. The Table of Contents lists: Paths of Travel, Recreational Trails, Beach Access Routes, Outdoor Public Use Eating Areas, Outdoor Play Spaces, Accessible Parking, Obtaining Service in Public Spaces, and Maintaining Accessible Public Spaces.

Ageing is more than a health issue

Guidelines, toolkits and policy frameworks related to population ageing have been around for a while. But are they being used? Ageing is more than a health issue – it’s an urban planning issue as well. COVID-19 has made this very apparent. And so has the 2023 Intergenerational Report. A case study based on Greater Sydney highlights the issues.

The authors discuss an “ageing city” in the first part of the article where they focus on Australian data on ageing and dementia. The second part of the article provides more information on what is working well and what needs to change. The article uses data, state and city policies to assess how well Greater Sydney is doing as a city for older people.

Key themes

Sydney has many blue and green spaces that are great for mental and physical health. However, these are inequitably distributed across eastern and western parts of the city. Access to shops and services likewise.

Active and social places are for the most part good for everyone. Quiet places are important too especially for people with dementia. Feeling safe is related to how active an older person is in their community. The more they get out and about the less worried they are about crime.

The researchers report on interviews with health and planning professionals, and provide several first hand quotes.

Key themes from the interviews included: the need for intergenerational spaces, considering mobility and distance between key services, and better access to gardens. Familiar landscapes and architectural landmarks provide a sense of security along with quiet ‘slow spaces’. Ageing and dementia could get lost when nested under policy words such as “liveability” and “universal design”.

Many things are possible and easy to do if planning and health professionals work together. That seems to be the way to go.

The last part of the article discusses the many toolkits, guidelines and policy frameworks for age-friendly cities. They range from international policies through to the work of the Greater Sydney Commission. The article concludes with recommendations.

The title of the article is, Age-friendly urban design and mental health in Sydney, Australia: a city case study. It is published in the Journal of Urban Design and Mental Health Edition 7: Aging City. There are other articles on the same topic in this edition.

Authors are, Safia Moore, Associate at Arup, and Georgia Vitale, Practice Leader at Grimshaw.

Size matters in urban design

Walkability is much more than paved walkways. To encourage people to get out and about, places and spaces need to be inviting. We know that urban design impacts our health and wellbeing so it’s important to get it right. Whether people go by foot, e-mobility or mobility device, size matters in urban design. Nikola Babic says that the scale and form of buildings has a big impact on walkability. Height and width of places and spaces play their part. For example, the sense of scale is blurred when streets are too wide. Active frontages such as shops and cafes, good lighting and a sense of safety are critical factors in attracting pedestrians. Green infrastructure is another important element to include. With the outbreak of COVID19, more people are aware of the importance of walking. However, most footways are too narrow to provide physical distancing. A good case of where size matters. It also matters for accessibility. Having welcoming streets should be part of the accessibility plan. Babic discusses the “superblock model” in Barcelona and the 15-Minute City in Paris as examples of what works and what doesn’t. His article is very readable and good for anyone new to this topic. Babic encourages discussion with others to further develop ideas. Babic ends with, “This short paper is just a beginning of a more in-depth research of walkable and ‘healthy’ urban forms which will explore the complex relationship between the history of urbanism, urban form, urban design, social processes and well-being.” The title of the article is, Superblocks – The Future of Walkability in Cities? It can also be downloaded from the Academia website.

Heritage no barrier to accessibility

Medieval cities with cobblestones, castles and Roman city walls are not the most disability-friendly places. And they are not easy to make accessible either. However, heritage is no barrier to accessibility in five European cities. They’ve made accessibility a top priority thanks to technology, design and engineering so that heritage is no barrier to accessibility.

The five cities are the Dutch towns of Breda and Rotterdam, Lyon in France, Slovenia’s Ljubljana, and Chester in the UK. The motivation is that these are popular tourist destinations. These examples show that where there is a will there is a way.

Some of the solutions are:

- lifting cobblestones, slicing them and re-laying them upside down
- an app that lets you tell the council about paving issues and follows progress until the remedial work is completed
- sound beacons that tell blind people when and what bus or tram is pulling into the stop
- an app for the most accessible restaurants, hotels and hotspots
- building cascading ramps to the upper walkways of ancient city walls

Part of the motivation is the tourist trade, both nationally and internationally. However, the EU also takes inclusion seriously and gives access awards to cities that prioritise accessibility in urban planning. The title of the article is Cities without barriers. Heritage is no longer an excuse for exclusion.

Medieval cities need not be “disabled”

When the user of a place or thing is most likely to be a person with disability, it is often labelled “disabled”. But what about places being disabled? “Disabled” in it’s original meaning is something that doesn’t work. So, if the chain of accessibility for everyone is missing, the place is indeed disabled. This was pointed out in an article in The Guardian: “People aren’t disabled, their city is“.

The story is about the Dutch medieval city of Breda – now one of the most accessible in Europe. This is because there is “joined up” access throughout – not a bit here and a bit there. They have pulled up cobblestones and re-laid them upside down to create a flatter surface. Hotels are on board too. The key point is that the local authorities have a commitment to inclusion and accessibility and that’s what makes the difference. The next major step will be improving digital communication. See the article for more information.

How will we know when we have achieved inclusion? It will be the day when separate labelling for places and things is no longer required.

Walkability in neighbourhood design

Health professionals say the lack of walking is a major factor in poor long term health. But do planners consider the breadth and diversity of the population? Perhaps we need a broader definition of walkability in neighbourhood design.

Lisa Stafford and Claudia Baldwin discuss the issues in their paper. They say few articles on walkable neighbourhoods include people with diverse abilities across the age spectrum. We need to design equitable space – places where everyone is welcome. They recommend that studies on walkable neighbourhoods encapsulate diverse abilities and ages.

The title of the article is, Planning Walkable Neighborhoods: Are we overlooking diversity in ability and ages? It is available through Sage Journals via your institution. Or you can access for a free read through QUT e-prints.

Walkable, rollable, seatable, toiletable

We need a broader term than walkable to explain how everyone can be actively mobile in the community, says Lloyd Alter. In his blog article he adds that unless you are “young and fit and have perfect vision and aren’t pushing a stroller… many streets aren’t walkable at all…” Alter takes his point from a new book where other terms are coined:

- Rollability. Walkability isn’t enough anymore
- Strollerability, for people with kids
- Walkerability, for older people pushing walkers
- Seeability, for people with vision impairment
- Seatability – places to sit down and rest
- Toiletability – comfortable places to go to the bathroom

“All of these contribute to making a city useable for everyone. So we need a broader term for this” says Alter. His suggestions are activemobility, or activeability to cover all the ways different people get around in cities. He says he is open to suggestions for a better word.

The title of the blog article is, We need a better word than ‘walkable’. The title of the book is Walkable City Rules by Jeff Speck.

Pedestrians First: A Walkability Tool

Cities are expected to hold seventy percent of the the world’s population by 2050. In planning terms that is very soon. Encouraging walking is talked about as if it was just a matter of persuading us to do it. However, planners and urban designers need to focus more on pedestrian needs and find out what the barriers are to getting out and about on foot and with wheels. The Institute for Transportation and Development has a new tool, Pedestrians First: Tools for a Walkable City.

Joe Chestnut, author, says, “but walkability is not just a sidewalk, it’s a whole system of design and infrastructure”. The tool aims to create a better understanding of walkability and ways to measure features. Their interpretation of walkability also includes people with disability. Best practice examples from around the world are provided. But note – an even footpath or sidewalk is still required!

What about the stairs?

Walkability is discussed as the solution to keeping people active and engaged in their community. A research study on stairs and older people concludes that the presence of stairs “may deter older persons (and others) from walking outdoors.” The study was a systematic review of the literature. The full article is available online from BMC Public Health. Or you can download the PDF. The title is “Examining the relationships between walkability and physical activity among older persons: what about stairs?” by Nancy Edwards and Joshun Dulai.

Lack of accessible housing causing most problems

What are the social inclusion obstacles in the built environment, who do they affect, and how? There’s a good amount of research on accessibility in the built environment. There’s also a lot of research on accessible housing design. However, the two are rarely discussed in tandem. While identifying the obstacles in the built environment for people with disability, researchers found that it was a lack of accessible housing causing the most problems. Researchers at Deakin University were looking for social inclusion obstacles in the built environment. They wanted to know what aspects were key for people with disability. While many were found, most issues could be traced back to a lack of accessible and affordable housing. In short, they found that housing was at the centre of multiple issues creating obstacles for living meaningful lives. Several workshops were conducted in the regional city of Geelong. Stakeholders included people with disability. Access to appropriate and affordable housing was a key factor across all the workshops. It affected employment, connecting with family and friends, transport, services and facilities. While it is important for people with disability to have an accessible home, all homes must be accessible so they can visit neighbours and feel included in their community. This point is often lost on policy-makers. Another factor not often mentioned is the ability to engage with the community to influence attitudes. That is, unless people with disability could get out and about, get a job and get to the shops, they will remain invisible, and nothing changes. Consequently one of the recommendations was to raise awareness of attitudes towards access and inclusion across different professions. There is a lot to unpack in this article including a discussion on co-design and whether it has the desired result. Universal design is discussed in the context of built environment courses. Also available from SpringerLink with institutional access. The title of the article is, “Housing at the fulcrum: a systems approach to uncovering built environment obstacles to city scale accessibility and inclusion”. The research was conducted before the Australian Building Codes Board completed their cost benefit analysis on accessible housing.

Extracts from abstract

This paper describes a study determining actions to overcome unintended obstacles in the built environment to city-scale accessibility and inclusivity. Prior studies have largely failed to connect social inclusion obstacles in the built environment with factors leading to social exclusion in other domains. An approach based on systems thinking allowed a wide range of stakeholders, including many with lived-experience of disability, to exchange ideas. One hundred and nineteen actions were identified to overcome these obstacles, with 37 of these prioritised according to impact and feasibility. Nineteen of these 37 are imbedded in the built environment. Access to appropriate and affordable housing was identified as a key factor across all domains. Access for people with disability to appropriately designed and affordable housing was at the fulcrum of many other issues which created obstacles to meaningful living and fulfilled lives. The process showed how housing is impacted by, and has impacts on, a wide sphere of socio-political and physical contexts.

Comparing the age-friendliness of different countries

Older adults spend more time at home compared to other age groups and want to stay in their home as they age. Ageing in place is a broad concept. Attachment to home and place play a key role in the wellbeing of older adults. Consequently, remaining “in place” minimises early entry into supported accommodation. An article by Hing-Wah Chau and Elmira Jamei compares Australia with some of the work on age-friendliness in other countries.

The article covers familiar ground of the WHO Age Friendly Cities program and discusses three aspects related to the built environment. Public spaces, housing and buildings, and public transport. The title of the article is, Age-Friendly Built Environment.

Housing

The UK Lifetime Homes Standard eventually influenced the development of a mandatory code for accessible housing in the UK. The lowest level of the code is now considered too low and will be upgraded.

So far, the 2010 Australian Livable Housing Design Guidelines have failed to bring about change to the building code. However, in April 2021, state and territory jurisdictions agreed to a basic level of accessibility in all new homes. However, two states have specifically refused to act on this. For more on this check out the posts in the Housing Design Policy section of this website.

The European Homes4Life scheme covers more than building design. It covers physical, outdoor access, economic, social and personal domains for new and existing residential buildings. Affordability, privacy, dignity and connectivity are all considered. Also included is smart technology.

Public spaces and transport

Outdoor spaces need to be welcoming of older people and encourage social interaction. Mixed use developments, housing diversity, pedestrian safety and natural landscapes all get a mention.

Walkable neighbourhoods and frequent, reliable and safe transport options are key to ageing in place. Affordability is also a consideration for people with minimum incomes. Cycling is also part of the active ageing agenda. However, car ownership is the best mobility option for people living in outer suburbs.

The article compares some of the work in other countries with Australia rather than offering something new. However, the conclusions draw attention to an important point. The design and planning of the built environment needs to hear the voices of those often excluded. Co-design collaboration is worth the time taken, and should be extended to other decision-making processes that affect their neighbourhoods and ability to remain active.

Dr Hing-Wah Chau presented a paper at the 2021 Universal Design Conference in Melbourne. The topic is about introducing students to universal design through community design studios.

Mapping the inconveniences of urban life

Town access audits are not new, but these alone do not gauge accessibility for everyone. Mapping the inconveniences of urban life for people with disability gives a better understanding of why isolated access features are insufficient to provide access for everyone. Access features are required in new works and major refurbishments. That means a lot of infrastructure remains inaccessible in our cities. It also means that accessible places aren’t joined up very well, or not at all. In a book chapter about the urban circle of life of people with disability, Katarzyna Ujma-Wasowicz explains her mapping project. The project involved a diverse group of people with disability. The aim was to see how they navigate the built environment. This sounds like a simple and obvious thing to do, but few planners and architects do this.

The mapping process

The mapping process involves the person with disability specifying a path from home to a destination and back home again. An auditor or researcher follows the person and takes detailed notes along the way. The results of these observations can inform decisions about the most critical rectifications needed. Ujma-Wasowicz acknowledges that designers think, “in best faith” about access for each disability group independently. At the end of the chapter she has a section on Post-Pandemic and Universal Design. Ujma-Wasowicsz notes that COVID has changed our behaviours but these changes don’t affect everyone equally. She proposes a universal design approach for design strategies in the summary.

“Therefore, a holistic approach to planning is necessary, where one of its elements should be audit of public spaces accessibility. The “urban circle of life” can be a useful tool for such inspection.”

The title of the article is, The Urban Circle of Life of People with Disabilities: Mapping urban inconveniences. The chapter and the book, Mapping Urban Spaces is available online from Taylor Francis. It is open access. This is a wordy read, but worth the effort if wanting to replicate this process and model. Although some local councils have embarked on similar exercises, there is little written about them in the literature.
