Improving Accessibility in the Built Environment

Mary Ann Jackson February 3rd, 2019

 

The pervasive ideology of institutionalisation in the past has meant that we have inherited a built

 

environment that is largely inaccessible to people with disability. Accessibility specialist Mary Ann

 

Jackson outlines her important work on the assessment tools and required action for improved

 

accessibility in the built environment.

 

 

What might an accessible built environment involve? Perhaps empowering people with disability,

 

systematically improving accessibility at neighbourhood scale, and generating meaningful

 

collaboration between built environment practitioners and people with disability would be a good start!

 

But in order to do this, we need to understand how historical models of disability – particularly the

 

charity/institutional and medical models – have compromised built environment accessibility by

 

rendering the public profile of people with disability virtually non-existent. A crucial consequence of the

 

once pervasive ideology of institutionalisation, which reached its peak under the medical model, is

 

that much existing built environment, particularly within the public realm, is inaccessible for people with

 

disability.

 

 

 

 

More contemporary models, such as the social model and the human rights model, may provide some

 

pointers for improvement. In distinguishing between impairment and disability, the social model

 

deems disability to be socially constructed. Disability is not ascribed to an individual’s impairment but,

 

rather, results from interaction between body and environment. The lived experience of disability is,

 

therefore, directly linked to the built environment. Central to the human rights model is that all people

 

have rights, including that of built environment access. Via the United Nations Convention on the

 

Rights of People with Disability (UNCRPD), the human rights model specifically draws attention to the

 

wide-ranging nature of the built environment – for example, housing, public buildings, transport, and

 

social/cultural/recreational locations. Spatial inclusion at the community level is embedded, and the

 

way people are supported to interact with their (neighbourhood) environment is considered crucial.

 

Bridging the divide: Rethinking accessibility

The 2017/18 temporary MPavilion – Legislation doesn’t adequately cover ‘temporary’ installations, another reason for the need for more interaction between built environments and people with disability.

 

 

 

Built environment practitioners are intimately involved in determining built environment accessibility

 

outcomes. However, corroborated by extensive professional experience and literature, a disability /

 

built environment separation is apparent within both professional and academic arenas. How might

 

this be bridged? Many disciplines relevant to ‘neighbourhood scale built environment accessibility’

 

have been working with ‘complexity theory’, ‘complex adaptive systems’, and ‘cities as complex

 

adaptive systems’ in recent times. Sustainability science’s take on complexity theory as ‘socio-

 

ecological interaction’ is potentially useful, as it allows us to think about socio as people, and

 

ecological as environment, and then to think a little more specifically about people as people with

 

disability and environment as built environment. But the built environment is built – it does not self-

 

propagate. It is, therefore, incumbent on those within the built environment domain working within

 

complex, people-environment systems, to consider people–people interaction, particularly interactions

 

that impact built environment accessibility outcomes for people with disability.

 

 

Nevertheless, at the close of the second decade of the 21st century, people with disability are still

 

frequently voicing their dissatisfaction with the (in)accessibility of the built environment. Why is this?

 

From a legislative perspective, there are instruments in place. For example, internationally there is the

 

UNCRPD. In Australia, we have the Disability Discrimination Act and Disability Standards, relevant

 

State Government policies, and local government Disability Action Plans. But the legislative and policy

 

landscape is complicated. On one hand, there is much technical jargon in the ‘built environment’

 

legislative documents, and on the other ‘policy speak’ in the ‘disability sphere. It is difficult for each

 

‘side’ to comprehend the other, particularly as they tend to also inhabit different sectors. From an

 

accessibility assessment perspective, there is built environment performance measurement,

 

interdisciplinary accessibility assessment, walkability evaluation, and access auditing. But

 

consideration of people with disability is lacking and people with disability are rarely directly involved

 

in the processes.

 

 

Built environment form and content is controlled by built environment practitioners. And built

 

environment form and content significantly determines built environment accessibility outcomes. My

 

PhD literature review indicates that, worldwide, the greatest accessibility concerns of people with

 

disabilities are: housing, the public realm pedestrian environment, and public transport built

 

infrastructure. Coincidentally, these areas are least directly legislated, and cover the most physical

 

space! The literature review also indicates that neighbourhood built environment accessibility

 

assessment tools are lacking.

 

Transdisciplinarity: Working together

 

Improving existing built environment accessibility at the neighbourhood scale requires many diverse

 

actors working together: participatorily, inter-disciplinarily and cross-sectorially. Collaboratively

 

working together generating people–people interaction across disciplines, across sectors, and with

 

non-experts as active participants is, practically, a definition of transdisciplinarity. More specifically, my

 

work adopts the ‘practical’ approach to transdisciplinarity generally referred to as the Zurich approach.

 

Commonly referenced in socio-ecological inquiry, the Zurich approach offers clues in facilitating

 

diverse actors in multiple sectors across multiple domains of research evidence, policy,

 

implementation, and practical application to work together to deal with complex problems such as the

 

retro-fitting of existing communities.

 

 

In my mind, there is little doubt that to effectively address neighbourhood-scale built environment

 

inaccessibility, a new (built environment) paradigm is needed that embraces complexity theory, the

 

social model of disability, transdisciplinarity, and (disability) human rights–based approaches. This

 

involves rethinking the way that the built environment is delivered. However, built environment

 

practitioners are largely unaware of disability, people with disability as rights-holders, and the

 

significance of their own duty-bearer status (as controllers of the built environment). Reductionist,

 

‘straight-line’, problem-solving approaches that ‘begin’ at the ‘design’ stage and that disregard people

 

with disability are grossly inadequate. Transdisciplinarity, involving all actors working together across

 

disciplines and sectors, has potential utility in the process of improving neighbourhood built

 

environment accessibility because all built environment is, in fact, people-instigated.

 

The Universal Mobility Index (UMI): A vital tool

 

Improving the situation requires an understanding of existing conditions, and a comprehensive

 

assessment is an imperative. Therefore, I am currently undertaking my PhD exploring the role of the

 

Universal Mobility Index (UMI) in improving neighbourhood built environment accessibility for people

 

with disability. This follows on from the work that Ralph Green (my late husband) and I have been doing

 

over the past years in the ‘Accessibility in the built environment at neighbourhood scale’ space. Ralph

 

and I pioneered the UMI, which is a method of assessing the accessibility of neighbourhoods as a

 

whole. The UMI, as a tool, is methodologically intended to function as a rights-based indicator of built

 

environment accessibility for people with disability at neighbourhood scale. An essential and defining

 

feature of the UMI is the dual componentry of built environment and policy environment. The built

 

environment component captures people with disabilities’ lived experience of existing neighbourhood

 

built environment accessibility. Built environment subcomponents are: infrastructure, public buildings,

 

commercial buildings, and private dwellings. Built environment accessibility assessment is undertaken

 

by people with disability themselves, another essential and defining characteristic of the UMI tool. The

 

policy environment component captures human rights, disability discrimination legislation, and people

 

with disabilities’ effective voice in policy making. Policy environment subcomponents deal with human

 

rights and legislation, and policy and representation.

 

 

In 2011, a UMI pilot was conducted in Kensington (Melbourne, Australia). The pilot area was divided

 

into segments corresponding to manageable assessment sessions of around 90 minutes. Site

 

assessors came to a consensus on the accessibility of each element inspected. Overall, the built

 

environment component value in Kensington was 0.48 (out of 1.00) – in short, definitely a fail! A policy

 

environment questionnaire was distributed to a wide range of local government, and NGO/ NfP

 

stakeholders. Answers were converted to an index value between 0.00 (would require all ‘no’

 

responses) and 1.00 (all ‘yes’ responses). The policy environment component value in Kensington was

 

0.64. The final UMI score, the average of the built environment and policy environment scores, was

 

0.56 – obviously not an optimal score.

 

 

The UMI as a measurement tool provides a snapshot of ‘existing conditions’ at neighbourhood scale. It

 

does not, in itself, physically improve built environment accessibility. How then can this be achieved?

 

Who has the say at neighbourhood scale? Is local government best placed to pursue improvement?

 

Perhaps, but in this privatised era, contemporary local government authorities often feel they have

 

limited power over the delivery, maintenance and renewal processes of many common neighbourhood

 

elements. The resultant limited and/or self-limiting agency within the public bodies can result in a lack

 

of ability and motivation to act. Therefore, motivating those who are ultimately the controllers of built

 

environment accessibility outcomes – ie, built environment practitioners – is necessary. Implementing

 

strengthened legislation within a compliance bubble will only go so far. Meaningfully engaging with

 

people with disability and co-documenting existing built environment lived experience requires

 

interaction. Interaction preceding motivation to act is an established paradigm.

 

 

The overarching goal of all my work is to empower people with disability to realise inclusion within their

 

local community as they wish. Essential to that goal is the improvement of the accessibility of the

 

existing built environment at neighbourhood scale. Consequently, an essential component of my PhD

 

is the development of the UMI Tool into a transdisciplinary assessment process: the UMI Process. The

 

UMI Process will then be field tested and analysed for the purposes of exploring whether there is

 

potential for transdisciplinary assessment of existing neighbourhoods to generate an empathetic and

 

empowering (disability) human rights–based approach to built environment neighbourhood

 

accessibility improvement.
