1.5 Have you ever been in a traffic situation in which a driver assistance system would have been helpful?

yes
no

1.6 Warnings/Informations

2. Intersection assistant
Accidents at intersections are frequently caused by miscalculation of speeds and distances, or failure to see traffic signs (including traffic lights) by the driver. The 'intersection assistant' detects such critical situations at intersections and supports the driver with additional information, warnings and/or interventions.

2.1 In your opinion, which one of the following situations could most likely lead to you having an accident at intersections?

overseight of cyclists when turning
left
right
oversight of pedestrian while turning
left
right
oversight/miscalculation of the velocity of an oncoming vehicle while turning left despite clear view
oversight of an oncoming vehicle while turning left because of view occultation or glare
oversight of a traffic sign that reminds me that I have not the right of way
unintended passing of red traffic light
oversight/miscalculation of the velocity of crossing traffic despite clear view
oversight of crossing traffic because of view occultation or glare
miscellaneous:

2.2 Have you ever been involved in a critical intersection situation?

no

yes (more than one answer can be marked)
oversight of cyclists while turning

oversight/miscalculation of the velocity of an oncoming vehicle while turning left despite clear view
oversight of an oncoming vehicle while turning left because of view occultation or glare
oversight of a traffic sign that reminds me that I have not the right of way
unintended passing of red traffic light
oversight/miscalculation of the velocity of crossing traffic despite clear view
oversight of crossing traffic because of view occultation or glare
miscellaneous:

yes. How?

no

"An intersection assistant which indicates only the right of way is helpful"
