FROM OUR DIRECTOR As we see 2020 moving into our rearview mirrors, this year has been one of challenges and opportunity. Doing driving research in the COVID-19 era has been a test for us and the University of Iowa more broadly. While many are diligently working from home, a handful are working in the facility while maintaining safe distances and following proper safety precautions. We worked hard to develop innovative protocols to keep our staff and research subjects safe inside our vehicles—whether in the simulator or on the road. Working with our global experts in infectious diseases at the University of Iowa Carver College of Medicine and internationally, we have taken the lead and developed in-vehicle protocols for our internal use as well as shared with the broader research community around the world. In addition to dealing with COVID-19, we have made great strides this year in advancing the future of auto safety. The U.S. Department of Transportation award of the Automated Driving Systems (ADS) for Rural America contract was a validation that the NADS is among the most competitive and cutting-edge labs in the United States. This $7 million contract gets to a big gap in ADS research: rural America.

Unlike Silicon Valley and other 12-month sunshine states with dry roads, Iowa has more challenging roadways and environmental conditions—from narrow unpainted roads, to gravel and farm equipment. And not to mention winter! Together with our many partners, we will continue to lead at the national and international level. These strides are not possible without our energetic, innovative, and nimble staff, students, and faculty. They provide the fit and finish that makes our research shine in global automotive safety. Peruse these pages, and our dedication and quality will speak for themselves.

‘MISSION FIRST, PEOPLE ALWAYS’ Harriet Nembhard became dean of the UI College of Engineering in June 2020
Harriet Nembhard’s research has taken a multidisciplinary approach to manufacturing and health care systems engineering. Her father was a captain in the U.S. Air Force, and she encapsulates her approach to leadership by borrowing the familiar military motto, “Mission first, people always.” “‘Mission first’ means that we invest in the academic institution that we want to realize,” says Nembhard. “‘People always’ means that we prioritize the success and well-being of everyone in our community. I believe that putting these together propels us forward as a community of inclusive excellence.” Q: How do you see the work that NADS does as contributing to the overall mission of the College of Engineering? A: The work done at NADS fits squarely within our college mission in a number of key ways: it fosters a community that values respect and inclusion; it forges critical research and innovations that improve human health; and it engages industry, state, and federal agencies in partnerships that advance knowledge and promote economic development. I am eager to see how NADS can further embrace our public education mission, engage more young people in engineering, and help expand the community of researchers. Q: NADS and its research program have now been around for more than 20 years. How does it fit more broadly into the mission of global health and safety? A: NADS has indeed made the University of Iowa a global leader in vehicle safety research. As driving technologies continue to advance, research underway at NADS will make
these technologies safer and more reliable for everyone. The next generation of automotive safety research will have a profound impact on human health around the globe. I am also encouraged by the industry relationships that NADS has fostered over the years, relationships that highlight the real-world impact of our research and the economic value of engineering scholarship. Not only is NADS seen as an invaluable resource for industry partners, but it is also a critical source of data and information for government agencies and regulators who will determine what technologies can be promoted in the marketplace. Q: You have expressed an intrinsic interest in technologies that are being developed at NADS. What is your personal interest in automated vehicles? A: Without a doubt, automated vehicles are in our future. As a current driver of a Tesla, I may even find myself using these automated functions soon. The only way in which automated vehicles can become more mainstream, beyond lowering the price, is if consumers and government find them to be as safe as human drivers. In addition, not all vehicles have the same on-road performance and experience, which is why NADS’s current project on automated driving on rural roads is so important. These automated technologies need to be accessible to people who drive on highways in Chicago and Los Angeles as well as those using side roads in Mount Vernon and Pella.

Project goals 1
Improve safety on our nation’s roadways with the integration of automated driving systems, as an estimated 94 percent of serious crashes are due to human error.
“Mobility means independence for a lot of these folks who cannot drive themselves, such as the elderly or those with certain disabilities. So in a few decades when fully automated vehicles become more common, this population could have a lot to gain from this technology.”
2
3
Represent rural roadways in AV research, exposing the vehicle to sharp curves and grades, gravel and unmarked roads, animals or slow-moving equipment on the road, and a variety of Iowa weather conditions.
Broaden mobility and improve quality of life: Show how automated vehicles can provide transportation options for those not able to drive, such as aging populations and those with disabilities.
The route The shuttle bus will follow a 47-mile route through Iowa City, Hills, Riverside, and Kalona and navigate parking in each city. A safety driver will be behind the wheel at all times.

Data
Our vehicle has been all over the Midwest in its production journey. An American-made vehicle, the Ford Transit chassis was assembled at the Ford plant in Claycomo, Missouri (a suburb of Kansas City).
Data will be publicly available on our website after each of the eight increasingly complex phases of the project, the first to begin in summer 2021. Data collected will help identify challenges, opportunities, and insights relevant for U.S. DOT safety and rule-making priorities. Types of data to be collected: • Video data from the safety driver to examine kinematics/performance/workload • Questionnaire data from the riders regarding trust and acceptance • Physiological data from riders and safety driver regarding stress/anxiety • Automation performance data, documenting challenges
Next it was sent to Starcraft Bus in Goshen, Indiana, where the body was installed and it was made ADA compliant (e.g., wheelchair lift added).
• Data on road surface state, grip, and surface temperature • Video data of participants will also be available, but will have restricted access to protect their privacy
Participants Individuals from local communities will be recruited in mid-2021 to be passengers in the vehicle. We will be looking at people’s comfort with the technology. Participants will:
Then it made its way to our partners AutonomouStuff in Morton, Illinois. AutonomouStuff is instrumenting it with automated technologies. In the meantime, our partners Mandli Communications in Madison, Wisconsin, will create high-definition maps of our route. We’ve also been partnering closely with the Iowa DOT.

NADS FEATURED IN IOWA MAGAZINE Iowa Magazine—the magazine for University of Iowa alumni and friends—featured NADS’s research on automated driving in their winter 2020–21 edition. The following is an excerpt, written by Josh O’Leary. Read the full text and watch new video coverage at:
FORIOWA.INFO/NADS
The past and present of transportation intersect not far from Iowa City. Near the small town of Kalona, just a 30-minute drive south of the University of Iowa, horsedrawn buggies clop through the Amish countryside on their way to the bakery or general store. Meanwhile, modern-day sedans and SUVs zip past. They’re guided by pinpoint GPS
mapping, lane-keeping cameras, and collision-detection systems that light up the dash when they approach a slowmoving buggy or tractor. Soon a vehicle from the future will also share the road here. UI engineers plan to roll out a new automated vehicle packed with research instruments for a multi-year study beginning in 2021. It’s not quite a DeLorean, but the customized, automated Ford shuttle bus will travel in a 47-mile loop, carrying research subjects through Iowa City, Kalona, Riverside, and Hills. Fueled by a $7 million research grant from the U.S. Department of Transportation, the vehicle will gather data on the challenges rural roads present to automated driving systems and study how emerging technology can help older residents in rural communities overcome mobility barriers. The project is the latest mile marker in a long history of roadway safety research by the UI-based National Advanced Driving Simulator. NADS has been an international pacesetter in studying how humans interact with their vehicles since 1992, when the National Science Foundation and the National Highway Traffic Safety Administration selected Iowa to host the center over five other universities. Many of the crash avoidance features that are now standard in automobiles were first tested at Iowa, and today, NADS serves as one of the world’s top hubs for advanced automotive driving research. . . . continued at foriowa.info/nads

ADAPTING TO COVID-19 NADS provides national leadership on COVID-19 driving research protocols Since the early days of simulation and in naturalistic driving, NADS has often taken the lead to establish the gold standard in human subjects research in our unique environments. This year was no different. With the help of many NADS staff members, Director Daniel McGehee made recommendations for human subjects testing in driving research for the COVID-19 era to the national Transportation Research Board’s (TRB) Committee on Vehicle User Education, Training, and Licensing mid-year meeting this past September. How to keep people safe in driving research—in both simulators and on-road vehicles—is not something that
had been widely shared or standardized in the driving research community, so McGehee sought to change that. McGehee consulted with various infectious disease experts, including Loreen Herwaldt, MD, a University of Iowa infectious disease and COVID-19 expert and epidemiologist. Members from the World Health Organization and the past president of the Canadian Infectious Disease Society also contributed to the recommendations. The recommendations (shown below) were met with an overwhelming positive response from the TRB.
RECOMMENDATIONS To safely conduct driving research in simulators and on-road vehicles during COVID-19: •
Subjects and experimenters wear three-layer surgical masks. Experimenters also wear a face shield when in the same room as a subject.
•
If experiments require an unmasked face (e.g., to read facial expressions), exclude on-board personnel if possible.
•
Minimize talking in a shared vehicle to reduce the expression of droplets.
•
Keep cooling fans on low speed.
•
Open windows/sunroof for fresh air.
•
Install HEPA filters in HVAC systems.
•
Use CDC appropriate cleaning protocols on all surfaces including windows in the vehicle or simulator cab before and after each subject.
•
Pre-screen subjects before and at arrival for the standard COVID-19 symptoms, and at arrival conduct temperature checks to ensure that they are not above 100° F.

A curtain added between the researcher’s desk and the quarter cab miniSim is one of many COVID-19 precautions. Drugged-driving team members Rose Schmitt and Timothy Brown test driving scenarios and the new setup prior to resuming human subjects research.
New protocols for the NADS facility Rewind to March 2020 when the COVID-19 outbreak began: University of Iowa research was suspended, and all staff were to work from home. Throughout the summer, a committee of NADS staff members developed 45 pages of guidelines to safely bring NADS staff back to work and resume research in a phased approach. First, a small handful of staff members began working in the building (only those who needed to be on-site), and eventually human subjects research resumed in late August. The vast majority of NADS staff members continue to work from home at the release of this Annual Report (December 2020). The new guidelines included disinfecting instructions, safety protocols for every area of the building and vehicles (including max occupancies), social distancing
and other signage, building traffic flow, meeting protocols, and building filtration updates, among other protocols. The team also established a new process and committee—called the Resource Access Coordination Committee (RACC)—that manages staff access to shared building resources (such as the use of the simulators or other shared work areas), and maintains a schedule to minimize the number of staff members in the building at any time. The NADS team has been incredibly adaptable in the face of these new challenges as we all learn how to safely live in a COVID-19 world.

CANNABIS AND DRIVING Taking alcohol, cannabis, opioids, or other drugs can significantly impact the ability to safely control a vehicle, as well as the ability to notice and respond to hazards on the road. Our research aims to understand • How drugs affect driving performance • The relationship of drug pharmacokinetics (how drugs are processed in the body) to the changes in driving performance, and • How impairment from drugs that impair driving performance can be detected.
Driving habits of regular users NADS researchers recently found that regular cannabis users drive differently than non-cannabis users—even while not under the influence of cannabis. Young adult drivers who use cannabis—but were sober at the time of our study—drove slower but also steered significantly less often and used the gas pedal less often than drivers who did not use cannabis. This suggests that effects of cannabis use persist and may lead to detrimental driving behaviors even after intoxication has subsided. These findings have implications for legislation in support of legalizing cannabis, because sober cannabis-using drivers may still be a public health concern.
When is it safe to drive after cannabis use? In drivers who are impaired by alcohol usage, there’s a clear way to determine when it’s not safe to drive. But how can you tell when it’s not safe to drive due to cannabis use? That’s the goal of an ongoing NADS study. The team is partnering with Advanced Brain Monitoring, who will be using the data for the development of an app called Cannabis Impairment Detection Application, which aims to detect levels of impairment due to cannabis use. “We want to know when someone is impaired so we can differentiate somebody who used cannabis two days ago, but it might show up on their system, versus somebody who used it an hour ago and is not safe to drive,” says Tim Brown, study PI and director of drugged driving research. The research team is observing brain activity during subjects’ reactions to stimuli; they are testing physiologic responses including blood pressure, heart rate, and where the eyes are focused; and they are measuring reaction times while braking or accelerating. Subjects will receive one each of three possible doses of THC across three study visits, one of which is a placebo dose. See some of our other major drugged driving research findings from the past 10 years at nads-sc.uiowa.edu/ drugged_driving.php.

DRUGGED DRIVING RESEARCH PROCESS Curious how we run our clinical research studies? Here are the basics.
Pre-award •
•
If we are developing the protocol, identify what is already known about how the drug affects performance, develop a study hypothesis, and define driving simulation requirements. Draft study protocol. If there is already a protocol, work with sponsor on details and timeline.
Study preparation and planning •
Drug supply is obtained. In the case of cannabis, it is federally supplied.
Recruitment, enrollment, and informed consent process
Screening human subjects • • •
Review inclusion and exclusion criteria, and verify eligibility. Conduct physical and psychological exams as appropriate. Screen for propensity for simulator sickness.
A research assistant demonstrates how vaporized cannabis is inhaled using heated air in place of cannabis.
Randomization: subject assigned to experimental condition
Data collection •
•
Follow detailed study procedures to dose subject: • For cannabis this is vaporization. • This could also be an encapsulated or intravenous administered drug. Collect study-related data (driving data, biological samples pre- and post-dose for pharmacokinetic analysis, etc.).
Cannabis vaporization procedure • • • •
Data processing and analysis
Reporting and results, summarize findings, study closure
• •
A dose of 500 mg of plant material is measured from the frozen supply. It is humidified in a secure storage area the night before use. The plant material is ground and then placed in the filling chamber. An inhalation balloon is attached to the chamber and then connected to the preheated vaporizer. The plant material is vaporized into the balloon. The balloon is then provided to the subject, who inhales the vaporized cannabis over a period of 10 minutes.

TEENS AT THE WHEEL When parents are in the vehicle with their teenage driver, crash rates are low. However, as soon as teens are by themselves, the crash rates skyrocket. Can new-driver training programs be used to effectively lower those rates? Elizabeth O’Neal, a postdoctoral researcher with NADS and the Department of Psychological and Brain Sciences, and Michelle Reyes, senior research associate, put teens into a simulator to find out. They posed the following research questions: • Does a teen’s ability to anticipate hazards on the roadway change after engaging with one of two novice driver training programs designed to improve hazard anticipation skills? • Does training improve hazard anticipation skills over and above independent on-road driving experience? In a project funded by the AAA Foundation for Traffic Safety and SAFER-SIM, they evaluated two novice teen driver training programs. Participants in the study: • Completed a baseline drive, then completed one of the two trainings (or neither if in the control group) • Returned after 6 weeks to do a post-training simulator drive • Returned after 4.5 months for a third, follow-up simulator drive
18 | nads-sc.uiowa.edu
The team is now in the process of analyzing data from the third drive. They are combining eye tracking and simulator data to code each driver’s level of situational awareness to better understand how well the novice drivers are perceiving and responding to potential roadway hazards. They plan to wrap up data analysis and reporting in FY21. So what’s next for O’Neal? “I’d like to find out: What can we do to more effectively train parents to be better instructors of their teen drivers?” she says. She hopes to modify one of the training programs and test its ability to train parents to be better driving instructors by comparing participants that do and do not complete the training.
Elizabeth O’Neal, postdoctoral researcher
Young driver study: Crash rates A project led by Michelle Reyes used state driver’s licensing data in combination with crash data to study young driver crashes. Crash rates based on the number of licensed drivers were calculated on a monthly basis to help evaluate graduated driver licensing policies in Iowa.
”I’ve been fortunate to collaborate with many great people at the Iowa DOT and the Statewide Traffic Records Coordinating Committee who care about using data to improve safety on Iowa’s roads.”
The major findings included: • Holding an instruction permit for a longer time prior to getting an intermediate license was associated with lower crash rates. • Minor school license (MSL) drivers had lower crash rates than intermediate drivers, but MSL drivers were also over-represented in fatal and severe injury crashes. • Older young drivers (i.e., 17- to 20-year-olds) holding instruction permits were over-represented in crashes and were also more likely to be driving without a supervisor in the vehicle. • Fatal crashes were much more likely to occur at night on summer weekends.
—Michelle Reyes, senior research associate
What’s next? Building off previous research, Reyes is working to calculate teen crash rates and crash characteristics by license type (instruction permit, minor school license, or intermediate license), age, and duration of licensure.
Paths to full licensure in Iowa Minor School License (MSL) Min. age: 14.5 Driver’s ed Hold for 6 mo.
No License
Instruction Permit Min. age: 14 Hold for 1 year
Full License Min. age: 17
Intermediate License Min. age: 16 Driver’s ed Hold for 1 year
Ongoing NADS/Iowa DOT projects are asking: What are the outcomes of motor vehicle injuries for adults in the back seat, and how do seatbelts affect the severity or types of injuries sustained?
What are the impacts of road conversions from 4- to 3-lane street configurations on businesses and emergency response in Iowa communities?
What do the coded numbers from crash reports really mean? Reyes is part of a team creating a crash data dictionary that will give users a better understanding of what really happened during a crash.

ARE DRIVERS READY FOR AUTOMATED VEHICLES? NADS is committed to making vehicle technology safer and easier to use. Our team is focused on understanding the challenges associated with varying levels of vehicle automation, from adaptive cruise control to full self-driving. To do this, we combine our expertise in human factors engineering and psychology with multimodal research tools, using a combination of high-fidelity driving simulators and on-road research vehicles to study the relationship between humans and vehicle technology. Here are a few highlights from the past year.
Mental Models of Vehicle Technology Research question: How does a driver’s understanding of adaptive cruise control affect driving performance? Sponsors and partners: AAA Foundation for Traffic Safety, SAFERSIM, and University of Massachusetts–Amherst Method: A questionnaire was developed to evaluate user understanding of adaptive cruise control (ACC), and users were grouped based on their understanding. Next, researchers compared driving performance in the NADS-1 simulator. The team recreated a Toyota ACC display in the simulator. Findings: Subjects with strong understanding of ACC responded earlier when the system failed to detect an object ahead. “We think this is due to uncertainty about how the system will behave,” explains John Gaspar, director of human factors research. “People who have poor understanding of the system come closer to collisions, because they tend to wait to see if the vehicle will respond.” Next steps: A second year of the project is tracking new owners of vehicles equipped with ACC to explore how user understanding changes over time during the initial interactions with a technology.
Rose Schmitt, research logistics, and John Gaspar, director of human factors research, in the NADS-1 simulator control room
User Experience Research question: Do people prefer a more conservative or more aggressive automated vehicle? How does that system behavior impact drivers’ trust and perception of the technology?
Subjective ratings and eye tracking data were both collected.
Sponsor: Hyundai
Findings: Users were more comfortable with automated driving systems that had conservative behavior (such as slower acceleration) rather than aggressive behavior. Comfort and trust also increased over time in both models.
Method: The project used the unique motion capabilities of the NADS-1 to create two models of automated driving behavior: an aggressive system and a conservative system.
Collaboration: A researcher from Hyundai Korea, Jayoon Goo, contacted NADS to do the study. He visited Iowa for nine months to work with NADS researchers on the project.
20 | nads-sc.uiowa.edu
Controlled Driving Studies Research question: How quickly do drivers transition back to control following periods of non-driving in automated driving? Sponsor: Toyota Collaborative Safety Research Center Method: On a decommissioned airport runway, a total of 155 subjects engaged in different non-driving tasks (such as texting or using the car’s interface) while driving the Tesla Model S75D in Autopilot mode. The Autopilot is set to turn off at a certain point, and researchers compare how quickly the driver transitions back to the control of driving. Collaboration and outcome: The video data from this study will be used by the University of California–San Diego to develop a computer vision algorithm that will classify how ready the driver is to take over based on where their eyes, hands, and feet are located.

Next steps: As part of a driver modeling study, NADS researchers have recreated events in the simulator. Next they will compare takeover time on the runway driving versus the simulator environment.
Transition of Control (TOC)
Thanks to our staff
Research questions: How does interface design impact transition of control in automated vehicles? How does the timing and sequence of messaging influence the transition from automation to manual driving?
Thank you to our research staff members below who collaborated on these projects, in addition to a number of development staff, other employees, and students who supported this work:
Sponsor: National Highway Traffic Safety Administration (NHTSA) Method: This project in the NADS-1 simulator is one of the first to look at driver behavior in a system that mimics a traffic jam. The system—called Traffic Jam Auto Drive—controls the vehicle during low-speed congested driving conditions. It was developed in-house and uses NADS’s automation model. NADS is studying both normal transitions and when the automation fails to live up to expectations.
• John Gaspar, PhD • Cher Carney, MS • Emily Shull, graduate student • Cheryl Roe, BS
Using the unique motion capabilities of the simulator, researchers don’t just identify if the driver is able to take over control, but also rate the quality of that takeover. “We’re finding that threshold between what’s safe and unsafe—so we need a high-fidelity simulator to do that,” explains Gaspar.
• Rose Schmitt, BS
Next steps: As part of a series of TOC studies funded by NHTSA, NADS also won a $1.45M award—announced in fall 2020. This one will ask: How long does it take to build sufficient situational awareness to safely resume manual driving? What are the risks if the transition time is too short? What’s the most effective interface and alert design for a safe transition?

CONNECTED SIMULATION CAPTURES REALISTIC HUMAN INTERACTION NADS recently wrapped up a multi-year project on connected (a.k.a., distributed) simulation funded by the Federal Highway Administration. While most simulations in driving research involve one human participant, this project involved multiple people interacting in the same virtual environment. A driver in the NADS-1 simulator could see and interact with an actual pedestrian who was wearing a virtual reality headset and walking around in another part of the facility. The pedestrian and the driver could see each other’s head and limb movement through their digital avatars, and they could gesture at each other to visually communicate. The goal? The team wanted to know if participants in the simulator would behave differently if they were interacting with the avatar of a real person instead of a computergenerated (agent) pedestrian.
The avatar of a real person accurately reflects the limb and head movements of that person.

The team completed three major aims for the project: 1.
Develop the technology for connecting real-time driving and pedestrian simulators.
2. Create realistic avatars to represent the tracked motions of real drivers and pedestrians. 3. Design and conduct an experiment in which pairs of naive drivers and pedestrians interacted in a shared virtual world.
Chris Schwarz looks over the shoulder of Shawn Allen while collaborating on a project.
Findings The research team concluded that there is benefit to using these types of interaction while studying safety. “It gave us a deeper understanding of how people interact,” said Chris Schwarz, director of engineering and modeling research. Not only were human drivers more likely to slow down and stop than the agent vehicles, but human pedestrians were also more likely to cross in front of human drivers than agent vehicles. So it did appear to affect the behavior of
both parties, even when over half of the participants couldn’t distinguish which simulations were avatars of real people and which were computer-generated agents. Two crossing types were compared: at junctions and at midblock. The agent vehicles were not programmed to stop at the mid-block crossings, whereas drivers were more likely to come to a stop or slow down at the mid-block crossings. When human pedestrians crossed at mid-block, the driver always stopped to avoid hitting them, but the agent vehicles often had a collision. Probability of a Collision

Creating compatible software In order for the driver to interact with a live pedestrian, two systems had to be merged: the NADS-1 software and the Unity3D game engine, used by the University of Iowa’s Hank Lab pedestrian simulator. Shawn Allen, engineering coordinator, led the creation of a new virtual environment (pictured right) and created an object database that was compatible with Unity. To do this, he developed a workflow to combine scripts and manually processed objects in the scenario library to Unity. This work was done under the Federal Highway Administration’s Exploratory Advanced Research (EAR) program based on a $1.8 million grant. The project was done in collaboration with the UI Hank Virtual Environments Lab and Visual Intelligence Lab. Interaction with bicyclists will be added in future work.

MEDICAL RESEARCH MEETS DRIVING RESEARCH Does exercise change symptoms and course of Parkinson’s disease? In one of many collaborations with University of Iowa Health Care, NADS is continuing its partnership with neurologist Ergun Uc, MD. In a clinical trial funded by the Department of Veterans Affairs and conducted at the University of Iowa, Uc is leading a study examining the long-term effects of aerobic exercise on movement, cognition, mood, sleep, fatigue, brain tissue, and driving performance in individuals with Parkinson’s disease (PD). The study compares two groups of people with PD over a year-long timeframe: one group that does aerobic exercise (2.5 hours of brisk walking per week), compared to another group that does online health education. Both groups are allowed
to exercise as they wish beyond the intervention randomized by the study. Will exercise improve driving ability in PD patients? That’s one of the many questions that Uc’s team is hoping to answer. Each subject participates in a baseline driving assessment, which will be followed by another drive one year later. A NADS research vehicle with data collection capabilities has been outfitted with cameras pointed on the subject, on the road ahead, and on each side of the vehicle to determine lane position. Video footage from each drive is analyzed by a blinded certified driving instructor to determine the number and type of driving errors. NADS Director Daniel McGehee, PhD, a co-investigator in the study, is in
charge of the driving component of the project. Cheryl Roe, head of research logistics for on-road vehicles, is coordinating the NADS research effort. She rides in the vehicles with the study subject to monitor the safety of the drive, along with a research nurse from the hospital’s Clinical Research Unit. NADS staff have also helped design the route, and they manage and house study data. Uc’s research team is looking to enroll around 100 people over the course of the study, which will likely wrap up in 2023. Details of the study “Long Term Aerobic Exercise to Slow Progression in Parkinson’s Disease” can be found at ClinicalTrials.gov and projectreporter.nih.gov.
“Having NADS expertise doing the driving assessment is a great asset. Driving function is a major outcome of this research, and without NADS here at the university we wouldn’t be able to do that. I know with NADS it will be done in a standard, reliable fashion providing a scientific method to evaluate driving. Our partnership has been fabulous.”
Cameras mounted on the exterior of the driver and passenger side doors capture lane position.

NEW OPTIONS, INTEGRATION ON MINISIM™ New options for miniSim systems enhance experience, expand research options
The miniSim is a PC-based driving simulator with powerful scenario editing and data acquisition capabilities. The miniSim is ideally suited to academic research and applied research and development applications. Hardware is available in three standard configurations: quarter cab, simplified cab, and desktop. It also supports custom cab and display system designs and user-developed subsystems.
New motion system provides more realistic miniSim experience
This miniSim configuration shows an infotainment system and a new D-Box motion system.
New or existing miniSims can now be equipped with a compact low-cost motion system from D-Box Technologies (d-box.com). Compact, durable actuators installed on the cab frame provide motion cues to the operator in three degrees of freedom (heave, roll, pitch), as well as vibration cues that change in response to road surface type (gravel, concrete, asphalt), vehicle speed, and engine RPM. These cues combine to create a more immersive driving experience for the vehicle operator, and enhance control of the vehicle.
Infotainment systems gaining traction on miniSim More miniSim clients are opting for an infotainment system for their new or current miniSim, which provides an OEM-style touch interface for tasks other than driving. It is integrated with the scenario control and data acquisition systems, so that the operator’s touch inputs are precisely recorded along with driving data.
Infotainment system
It also generates a moving map similar to a navigation system and provides audio playback of mp3 files and internet radio stations, simulated phone calls, and other tasks of the user’s own design. Available skins: Toyota Entune and Tesla Model 3 and S Multi-platform compatibility: Raspberry Pi 3+, Android and iOS, Windows

NEWS BRIEFS International scholars partner on research projects Visiting scientists from around the world come to NADS to work on research projects for sometimes months at a time and collaborate with our experts. One such example was in fall 2019, with Felix Ellensohn from the Technical University of Munich, Germany. A PhD research assistant in applied mechanics, he came to NADS to evaluate a motion cueing algorithm (MCA) with the motion simulation of the NADS-1 simulator. The NADS-1 provides a realistic driving experience, but it is a balancing act to get that simulation experience just right. To the driver, it must feel like they are still moving forward, while the simulator is actually returning to the center of the room in order to stay within its boundary (in a process known as MCA or washout). The MCA that makes this possible is what Felix was analyzing. His conclusion? He found that the NADS MCA provides a higher motion cueing quality than the one he developed and tested—which provided more evidence that effective motion washout is still something of an art.
