Outcome measures
Primary outcome
The main study parameters of the kinematic study is the van der Laan technology
acceptance scale. This scale has two sub-scores: one for usefulness and one for
satisfaction.
Secondary outcome
Secondary study parameters are the cycling speed and bicycle lateral
acceleration and steer angle, which represent cycling behaviour and bicycle
stability. The bicycle lateral acceleration is assessed from the accelerometer
in an inertia sensor attached to the frame of the bicycle. A speed measurement
device is mounted to the rear wheel. The steer angle is calculated from the
position of the inertia sensor attached to the steer relative to the one
attached to the bicycle frame.
Furthermore, from the semi-structured interview: Perceived usefulness,
Perceived ease of use, Subjective norm (opinion of others) and Identity to get
a better understanding of the underlying considerations and reasoning of the
older cyclist.
Background summary
In the Netherlands, older cyclists cycle more and up to a higher age.
Unfortunately this group is prone to injury due to a cycling accident. Some of
these accidents are related to issues looking behind, anxious feelings due to
unforeseen other road user interaction, or overlooking an obstacle on the road.
To support older cyclists in such situations, supporting devices have been
developed which are able to inform the cyclist well in advance of traffic from
behind and or for obstacle on the road. The supporting devices have been tested
in laboratory environments, but have not been evaluated or validated in real
life situations.
Study objective
The aim of this study is to assess the supporting function of the *Safe and
aware* bicycle, including the rear view assistant and obstacle detection, in a
group of older cyclists in safe real life situations. The aim of this study is
to analyse if these supporting devices fulfil the wishes and desires of older
cyclists and to which extent the supporting devices influence cycling
behaviour.
Study design
This study has a cross-sectional design, with one measurement sessions for
assessing the cycling behaviour of older cyclists on a bicycle with and without
the supporting devices.
Study burden and risks
The risks for the subjects are limited, since the cycling tasks represent
functional and familiar movements and are performed within a safe, pre-designed
and pre-directed environment. During the cycling tests the difficulty in task
increases slowly and can be stopped, by the subject self or by a present
therapist, at any time.. A Failure Mode and Effect Analysis is performed to
ensure there are no serious injury risks. In addition, the measurements used in
this study are all non-invasive and involve no risks to the subjects in any way.
Participation of a subject in this experiment has no direct benefit for
him/her, other than expanding knowledge about his or her cycling performance
and aiding in development of sophisticated tools to improve bicycle safety.
