Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameter of the cycling experiments is the van der Laan technology acceptance scale. This scale has two sub-scores: one for usefulness and one for satisfaction. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters are the cycling speed and qualitative video observations, which together represent cycling behaviour. A speed measurement device is mounted to the rear wheel. From the video recordings on fixed locations on the road, the cycling behaviour such as looking over shoulder, manoeuvring, sway, and distance and time of manoeuvring and sway, is described. Furthermore, from the semi-structured interview Perceived usefulness, Perceived ease of use, Subjective norm (opinion of others) and Identity are assessed to get a better understanding of the underlying considerations and reasoning of the older cyclist. | — |
