Abstract:In this project, researchers studied bicyclists’ safety perceptions of and preferences for roundabouts with different characteristics. First, the researchers performed a systematic literature review on bicycle safety at roundabouts, reviewing 49 different resources with empirical findings. Next, they developed a 20-minute online questionnaire to collect data from up to 613 U.S. adult bicyclists. The survey presented respondents with hypothetical roundabouts with various controlled design and operational attributes, represented using text and simulated images. The researchers then analyzed cyclist preferences from a discrete choice experiment and bicyclists’ perceptions of comfort.
