Below are some key findings via BikePortland.org from a survey conducted by the BTA (Bicycle Transportation Alliance)… It’s important to note that 89 percent of the cyclist reported owning at least one vehicle. This is notable in that it shows that cyclists do not greatly reduce vehicle ownership numbers, but rather trips taken by car.
Eighty-nine percent of cyclists also own at least one automobile.
Eugene rated their routes the safest and most accessible
Eugene also hat the highest percentage of weekly trips taken by bicycle with 55% over Portland’s 43%
The average number of bicycles owned increases as skill level improves [a good economic argument to encourage bicycling!].
In Northeast and Southeast Portland, 15% of respondents say they don’t own a car.
The percentage of trips taken on mass transit drops as the skill level of cyclist increases [likely because it's cheaper and faster].
As people’s perception of bike safety increased, so too did their amount of weekly bike trips (see chart below).
