Stinson and Bhat (199) using data from a web based stated preference survey estimate a logit model to understand important attributes for commuter cyclist route choice.

The results from these papers seem somewhat mixed. Though some of the research has shown a stated preference and revealed preference with some constraints for off-road facilities, others have shown that cyclists generally prefer in-traffic cycling facilities with bike lanes.

The overall assessment of the models suggests that designated bike lanes seem to be what are desired the most. It is also important to consider that both the linear and logit models found no evidence against the possibility that preferences between cyclists and noncyclists are the same.

The results show that D-12 users are willing to pay the highest price for designated bike lanes, followed by the absence of parking on the street and by taking a bike lane facility off-road. In addition, we are able to extract certain individual characteristics that are indicative of preferences such as age and household structure and make loose connections with sex and household income.
