Summary
Revealed-preference GPS route-choice study (Transportation Research Part A 2012) of 164 cyclists in Portland, OR carrying GPS units for several days. Authors mapped 1,449 utilitarian (non-exercise) trips onto a detailed bicycle network and estimated a path-size-logit route-choice model with permutation-based choice-set generation. Examined sensitivity to distance, turns, slope, intersection control, traffic volumes, and facility type (off-street paths, bicycle boulevards, bike lanes, bridges).
Key finding
Cyclists place high value on off-street paths, traffic-calmed bicycle boulevards, and bridge facilities; on-street bike lanes only offset the disutility of adjacent traffic and are no more attractive than a low-volume street; commute trips are more distance-sensitive and less infrastructure-sensitive than other utilitarian trips.
Methodology
Revealed-preference GPS data collection over multiple days; map-matching to a detailed bicycle network; choice-set generation via path attribute permutations; path-size-logit route-choice model accounting for overlapping alternatives.
