On the road with autonomous vehicles

A yellow autonomous vehicle on the road. It is box shaped with large windows and small wheels.What will the future of transport look like post COVID-19 pandemic and what will it mean for autonomous vehicles? For people who don’t or can’t drive, autonomous vehicles seem a wonderful invention. But will the designs and technology be inclusive?  

It’s not that no-one is thinking about access and inclusion – they are. But it’s not all about the technology. Some of the problems are related to the way vehicles connect with the built environment. Wheelchair accessible features, such as a ramp, can be rendered unsafe on steep inclines. If the wheelchair is not locked down, bumps in the road could cause the chair to tip or fall. 

Some riders will need specific assistive technologies for eye tracking, gesture recognition, and voice control. These would give people with tactile, mobility, and hearing impairments a sense of control without the need to make physical contact. Other practical challenges are around pick up and drop-off, and loading and unloading groceries. Human assistance will still be needed at certain points of the journey for some people. 

These issues and others are discussed in an article, Autonomous vehicles should benefit those with disabilities, but progress remains slow.

UTT: A Conceptual Model to Guide the Universal Design of Autonomous Vehicles requires institutional access for a free read.

Abstract:  Autonomous vehicles (AVs) are closer to becoming a reality in changing the landscape of commercial and personal transportation. The launch of these vehicles come with the promise of improved road safety, reduced traffic fatalities, and enhanced mobility. However, there are questions as to whether the design of AVs will meet the needs of everyone, including people with disabilities and older adults. We argue that there exists no conceptual model that guides the inclusive design of autonomous vehicles to benefit all intended users. This paper proposes such a model, called the User Transportation-Activity Technology (UTT) model, which supports the inclusive design of AVs. We present a review of current models of assistive technology design and their drawbacks followed by an introduction of the UTT model and its application in AV design. This paper may benefit researchers, designers, and developers of autonomous vehicles interested in addressing accessible design issues in such vehicles.


Older people like self driving vehicles

Graphic from the paper showing the elements people would think about when planning a journey with an autonomous vehicle.A series of workshops with older people in UK revealed they are likely to welcome autonomous vehicles. The workshops also gave participants time to think about some of the implications, both negative and positive.  Accessibility was a key factor. Declining vision and hearing, as well as dexterity issues such as arthritis, were mentioned in relation to touch screens. Being able to stop for a toilet, room for a pet and for shopping or luggage, and where to leave the vehicle at the end of the trip were factors that designers need to consider. There’s good information about older people and their reasons for travel, and how autonomous vehicles might enhance their ability to get out and about and socialise.

The title of the paper is, Finding from Workshops held with Older People considering participating in Connected Autonomous Vehicle trials. It also contains information about the five levels of autonomy of vehicles. The workshops are part of a larger project, Flourish, a multi-sector collaboration.

Editor’s note: Too many people are thinking about drivers and self-driving vehicles when in fact, fully automated vehicles are self-passenger-ing. That is, no-one is driving, so everyone is a passenger. 

The graphic from the article shows factors older people thought about when making a journey: toilets, luggage space, route choice, refuelling, journey time, leaving vehicle at destination, and road conditions.

Artificial Intelligence and UD

Internal view of a driverless car showing seats facing both back and forward.Artificial Intelligence and Universal Design are looking like natural partners in the development of new technology. In a recent article, “Tackling Autonomous Driving Challenges – How the Design of Autonomous Vehicles Is Mirroring Universal Design” the authors argue that the applying  the seven principles of universal design to the design autonomous vehicles is becoming more evident as the designs advance.

Abstract: In the future, the world will be characterized by highly densely populations, with growing share of mobility-impaired/disabled persons, a critical problem regarding the sustainability of the metropolises, whose resolution may reside in autonomous vehicles. A broader range of users will be allowed a, so far, denied mobility in level 4 and level 5 SAE autonomous vehicles, a goal to be accomplished through Universal Design, a design which intends to be the closest possible to the ideal design. For such purpose, Human Factors and Ergonomics are key. Literature review and research have shown that there is evidence of application of the seven Universal Design principles in these new autonomous vehicles and that, given the nature and purpose of the Universal Design, with the increase of autonomy, there is natural increased evidence of Universal Design. A novel model for interaction of the Universal Design influencers is proposed.
