This NHTSA Survey of Bicyclist and Pedestrian Attitudes and behavior is from 2012 but it is relevant today in 2017.
One startling take away is that cyclists do feel threatened on their bikes on a fairly regular basis:
When asked whether they felt threatened for their personal safety while riding a bicycle on their most
recent travel day, one in eight respondents that had ridden in the past 30 days reported that they felt
threatened during some point on their ride.
And no surprise, bicycle lanes and bicycle paths are important to cyclists, and being able to have one nearby where you live and work makes a difference:
Respondents who had ridden a bicycle within the past year and who have bicycle paths available within a
quarter mile of where they live were more likely to use bicycle paths for at least some of their rides
compared to riders not living near bicycle paths.
Though cyclists want the “Idaho Stop” and California cyclists may soon get this law, the majority of cyclists know to obey the same roadway laws as car drivers and do stop at stop signs and lights:
Nearly all respondents were aware that the rules that apply to motor vehicles regarding traffic lights and
stop signs also apply to bicyclists. More than 9 in 10 reported that a bicyclist must stop at traffic lights
and stop signs.
Everyone is a pedestrian.
Respondents who had walked outside for five minutes or more at least once during the past year were
asked how often they walk during the summer months. Four in five respondents reported walking at least
once a week. Very few respondents claimed that they never walked during the summer months.
