Rudy,
I went to the survey link, and quit because the questions weren't well designed. There's no allowance for differences between 1st and 3rd person, nor for folks who engage in multiple activities, or at different times or both. This carries through, for example as a walker in the daytime I may not dress for visibility (walk against traffic), while as a cyclist at night I may both dress accordingly, and use bright lighting.
I suggest you pull the survey, and redesign it, so it flows intelligently along the lines you want, ie day or night visibility, or sorted by activity, or asking that participants focus on one activity at one place and time, and keep all answers related to that only.
Good luck with your project, remember --- getting good answers depends on asking good questions.
