Outcome measures
Primary outcome
Objective scores derived from driving performance in driving simulator, main
study parameters are the number of crashes and traffic conflicts (near crashes)
and a compound score for hindrance to other traffic based on the deviation of
the speed from the optimal speed for the various road and traffic situations.
Secondary parameters are the average and standard deviation of lateral position
on straight sections and around intersections. Norm violations are also
investigated as well as workload, acceptance, and trust in the system.

Background summary
The number of older drivers still operating a vehicle is increasing rapidly.
With ageing, the prevalence of neurodegenerative disorders such as Parkinson*s
disease (PD) and Alzheimer*s disease (AD) increases. Even in very mild forms
these disorders lead to visual, cognitive, and motor impairments interfering
with driving, particularly in situations with time pressure and divided
attention requirements. Driving is very important for quality of life in older
drivers; therefore, methods to support impaired older drivers to remain safely
mobile are required. Advanced Driver Assistance Systems (ADAS) can play an
important role if they are tailored to the needs and capabilities of impaired
older drivers.
Study objective
The present PhD thesis focuses on the investigation of ADAS and the older
driver. Even though, recent research investigated the effects of ADAS on
driving performance, little is known about the long-term effects of the systems
on performance. Therefore, the central questions are whether and in how far the
use of general and/or tailored ADAS improves driving performance over time of
impaired drivers and in how far they appreciate the support given by the
system.
Study design
Mixed study design with repeated measures.
Intervention
For the purpose of the study, participants will repeatedly drive a 25 km city
drive in the UMCG driving simulator during which they will receive important
traffic related information. Important traffic information will be conveyed
through a head up display (HUD). Route information will be given orally. A
group comprised of healthy older drivers, drivers with mild cognitive
impairment and drivers with Parkinson*s disease who do not receive traffic
information throughout all trials will serve as a control group.
Study burden and risks
When driving in a simulator, some people experience simulator sickness, which
feels like motion sickness. Based on previous studies, the driving simulator at
the UMCG has been optimized with regard to the prevention of simulator sickness
and therefore in our regular clinical assessment, it is not a problem anymore.
In the experimental set up proposed here, several 90 degree turns must be made,
which we prevent in clinical assessment, so that more people might suffer from
simulator sickness. To prevent that from interfering with the research, a short
preliminary assessment is made in a test situation with many turns. People
complaining about simulator sickness will be excluded from the study.
