No ride, no healthcare:  New project provides “mobility wallets” to get residents to medical appointments

Two University of Michigan researchers are part of a community-based research project to get Detroit- and Dallas-area residents to doctors’ appointments, pharmacies and other health care services that often are skipped or inaccessible due to a lack of transportation.

Researchers Tayo Fabusuyi, assistant research scientist at the U-M Transportation Research Institute, and Lu Wang, associate chair for research and professor of biostatistics at U-M’s School of Public Health, will analyze and document how health outcomes are impacted by mobility intervention. Statistics they will track include morbidity, mortality, loneliness, stress, life satisfaction, access to health care and missed health care appointments.

The project is funded by a recently announced 10-year, $12-million ComPASS grant from the National Institutes of Health. It will document changes—ideally improvements—in participants’ health once a new “mobility wallet” program is introduced. It is aimed at removing a leading barrier to healthcare access: transportation.

Establishing a crash rate benchmark using large-scale naturalistic human ridehail data

This paper presents a study of human driving performance for the targeted geographic area of San Francisco.  The goal of the study was to generate a crash rate estimate that could be used as a human benchmark representing the crash rate for ridehail drivers driving in a lower-speed and dense urban driving environment.   

The study represents an unprecedented large-scale naturalistic ridehail data collection effort over a 2-year period from 2016 to 2018: a collaboration that took place between General Motors (GM), Cruise LLC, the University of Michigan Transportation Research Institute (UMTRI), and the Virginia Tech Transportation Institute (VTTI).

ATTAIN Grant: UMTRI to receive $9.8m for C-V2X deployment

The connected environment that researchers are pursuing allows vehicles to communicate with each other, infrastructure, the cloud and cellular networks, as well as pedestrians and other vulnerable road users. Where the Safety Pilot Model Deployment program previously utilized short range communications, C-V2X utilizes cellular communications.

In addition to the 21 Ann Arbor intersections already retrofitted with roadside units for data sharing, the new deployment will update 51 more sites in the area with C-V2X. 

Those units include: 

• 2 curve speed warnings
• 4 pedestrian mid-block crosswalks
• 39 intersections
• 1 roundabout
• 6 staging/test sites

UMTRI technicians will retrofit 100 vehicles with a low-cost aftermarket on-board unit. These vehicles will be used for coordinated testing with Michigan-based automobile manufacturers to accelerate vehicle deployment.

Evaluating Wheelchair Crashworthiness for Potential Use as Aircraft Seating

Sponsor: National Institute for Disability, Independent Living, and Rehabilitation Research (NIDILRR)

Researchers: Kathleen D. Klinich, Miriam Manary, Nichole Orton, Kyle Boyle, Brian Eby, Jennifer Bishop

Abstract:

Approximately 3.6 million people in the US use wheelchairs, but they cannot currently use them on aircraft, preventing many from flying. Among those that transfer to airline seating, many report instances of their wheelchairs being damaged during transport, as well as discomfort, injury, and social stigma experienced while transferring to an aircraft seat.

A recent National Academy of Sciences (NAS) consensus document determined that it should be feasible on most commercial aircraft to allow passengers to use their wheelchairs. However, wheelchairs would need to meet the FAA crashworthiness requirements for current aircraft seats. These consist of dynamic tests simulating frontal and vertical loading, plus static pull tests.

While voluntary, RESNA WC19 currently has standards for assessing frontal crashworthiness of wheelchairs used as seating in motor-vehicles. We hypothesize that wheelchairs meeting current RESNA standards for vehicles can meet the FAA crashworthiness requirements for airline seats. To test this hypothesis, we will construct adapted versions of the FAA test fixtures and test wheelchairs that meet current WC19 requirements under frontal, vertical, and static testing conditions. If needed, we would perform additional testing of wheelchairs with modifications made to improve their performance under FAA test conditions. We will also draft procedures that would adapt FAA seat testing standards so they can be used to evaluate wheelchairs.

Ground Truth Trip Recorder

This project is about creating a Ground Truth Trip Recorder (GTTR) that can be retrofitted to any AV and can serve as an independent, objective method for assessing its performance on the road, during on-road testing (similar to a driver’s license test).  This is a feasibility study for whether measurements can be precise, comprehensive, and automatable enough to support on-road testing and evaluation.

Smart Drivers Smart Options (SDSO) and Advanced Driver Assistance System (ADAS) Technology.

Sponsor: Michigan Office of Highway Safety Planning.

The project’s objectives are to reduce crashes and associated injuries related to older drivers in Michigan and to improve the quality of life and independence of older adults and the unpaid caregivers that provide transportation assistance to Michigan older adults, through an expansion of the Safe Drivers Smart Options (SDSO) strategy to include information about advanced driver assistance system (ADAS) technology. Activities include: gathering information about older drivers and ADAS technologies and organizing this information into a framework that can be added to the SDSO website; assessing awareness of the SDSO strategy in Michigan through surveys of the three target user groups for the SDSO strategy (Michigan older adults, Michigan informal caregivers who care for older for an older adult; and professionals who work with older adults on mobility-related issues); and integrating the ADAS information into the SDSO website and assist in marketing efforts.
