A significant portion of the global population about 13.6% of the world's population faces challenges due to upper limb disabilities caused by accidents, genetics, health issues or aging. These people struggle with everyday mobility tasks and often need help. Hence, the research is focused on creating special vehicle control systems to help them. This study gathers knowledge from various science and technology fields to develop foot-operated steering systems letting those with upper limb differences control vehicles with their feet. The research explores various technologies like modified steering, brain-controlled vehicles, foot-operated steering, steer-by-wire and Ackermann steering. Most of these systems are custom-made for people with upper limb differences. Ensuring safety, security, malfunction prevention, precise steering, user-friendliness and affordability is a significant challenge that demands advanced technology. Furthermore, there is a requirement to develop this system to

The goal of the automated mobility platforms (AMPs) initiative is to raise the bar of service regarding equity and sustainability for public mobility systems that are crucial to large facilities, and doing so using electrified, energy efficient technology. Using airports as an example, the rapid growth in air travel demand has led to facility expansions and congested terminals, which directly impacts equity (e.g., increased challenges for Passengers with Reduced Mobility [PRMs]) and sustainability—both of which are important metrics often overlooked during the engineering design process. Therefore, to evaluate systems and inform critical near- and long-term decisions more effectively, a holistic evaluation framework is proposed focused on four key areas: (1) mobility, with emphasis on travel time and accessibility within an airport, (2) environment, focused on energy consumption and greenhouse gas (GHG) emissions associated with intra-airport mobility, (3) equity, specifically to the

Challenges that persons with disabilities face with current modes of transportation have led to difficulties in carrying out everyday tasks, such as grocery shopping and going to doctors’ appointments. Autonomous vehicles have been proposed as a solution to overcome these challenges and make these everyday tasks more accessible. For these vehicles to be fully accessible, the infrastructure surrounding them need to be safe, easy to use, and intuitive for people with disabilities. Thus, the goal of this work was to analyze interview data from persons with disabilities, and their caregivers, to identify barriers to accessibility for current modes of transportation and ways to ameliorate them in pick up/drop off zones for autonomous vehicles. To do this, interview subjects were recruited from adaptive sports clubs, assistive living facilities, and other disability networks to discuss challenges with current public transit stops/stations. Responses to questions were recorded and later

Despite advances in automated driving systems and their potential help many mobility users who cannot drive, significant barriers remain regarding accessibility for emerging technology vehicles. These barriers exist in the design of vehicles and affect boarding, accessing pick-up and drop-off points, and traveling to a vehicle location. The accessibility of automated mobility services hinges on an interdependent set of vehicle design and infrastructure issues, both digital and physical. Automated Vehicles and Infrastructure Enablers: Accessibility highlights the development status of accessible vehicles and services, considers approaches to vehicle design that allow for increased accessibility, and examines the ways in which infrastructure can open the door to automated mobility for disabled customers. Use cases for accessible automated mobility service include local bus, paratransit, and robotaxis. Click here to access The Mobility Frontier: Accelerating Infrastructure Readiness for

Autonomous vehicles (AVs) have the potential to vastly improve independent, safe, and cost-effective mobility options for individuals with disabilities. However, accessibility considerations are often overlooked in the early stages of design, resulting in AVs that are inaccessible to people with disabilities. Vehicles serving people with disabilities typically require costly aftermarket modifications for accessibility, which may have unforeseen impacts on vehicle performance and safety, particularly in the case of automated vehicles. In this research, we investigate the performance of three autonomous shuttle design configurations: an off-the-shelf shuttle that is not wheelchair accessible, the campus pilot shuttle that is wheelchair accessible, and a new design using wheelchair accessibility foresight. Physics-based simulations performed using MATLAB, ADAMS (Automated Dynamic Analysis of Mechanical Systems), and Autonomie demonstrated that the modifications aimed at providing

The recommendations in this SAE Information Report apply to structural integrity, performance, driveability, and serviceability of personally licensed vehicles not exceeding 10 000 lb GVWR. While many of these recommendations may have application to other vehicles, such as those used in paratransit operations, the contents of this document are not directed at these types of vehicles

It is expected that Level 4 and 5 automated driving systems-dedicated vehicles (ADS-DVs) will eventually enable persons to travel at will who are otherwise unable to obtain a driver's license for a conventional vehicle, namely, persons with certain visual, cognitive, and/or physical impairments. This information report focuses on these disabilities, but also provides guidance for those with other disabilities. This report is limited to fleet operated on-demand shared mobility scenarios, as this is widely considered to be the first way people will be able to interact with ADS-DVs. To be more specific, this report does not address fixed route transit services or private vehicle ownership. Similarly, this report is focused on road-worthy vehicles; not scooters, golf carts, etc. Lastly, this report does not address the design of chair lifts, ramps, or securements for persons who use wheeled mobility devices (WHMD) (e.g., wheelchair, electric cart, etc.), as these matters are addressed by

The ability to independently transfer into and out of a vehicle is essential for many wheelchair users to achieve driving independence. This paper presents the results of an exploratory study that investigated the transfer strategies of wheelchair users who drive from their driver’s seat and not from their wheelchair. The goal of this study was to identify typical ingress and egress motions as well as “touch points” of wheelchair users transferring into and out of the driver’s seat. While motion databases exist for the ingress and egress of able-bodied drivers, this study provides insight on drivers with physical disabilities. Twenty-five YouTube videos of wheelchair users who transferred into and out of their own sedans were analyzed. The locations where the drivers’ hands, feet, and hips interacted with the vehicle, as well as the actions of the drivers while transferring from their wheelchair into the driver’s seat and then transferring from the driver’s seat into their wheelchair

This paper develops a design paradigm for universal products. Universal design is term used for designing products and systems that are equally accessible to and usable by people with and without disabilities. Two common challenges for research in this area are that (1) There is a continuum of disabilities making it hard to optimize product features, and (2) There is no effective benchmark for evaluating such products. To exacerbate these issues, data regarding customer disabilities and their preferences is hard to come by. We propose a copula-based approach for modeling market coverage of a portfolio of universal products. The multiattribute preference of customers to purchase a product is modeled as Frank's Archimedean Copula. The inputs from various disparate sources can be collected and incorporated into a decision system. Thereafter, an optimal portfolio is found through optimization which takes into account the disability level continuum while accounting for overlap demand within

The terms included in this SAE Information Report have been collected during the development of SAE documents related to standards for the adaptation of vehicles for use by persons with physical disabilities. It includes only those terms that are pertinent to the adaptive devices discipline, leaving to other authorities more common automotive engineering terms. Where several terms have a common meaning in the practice, the Terminology Task Force has attempted to select the most appropriate term. The Terminology Task Force recognizes that there will be a need to expand and update current terminology as advances in the industry occur, and as related standards documents are completed. Accordingly, they will continue to develop and maintain this document to reflect those changes
