The study involves taking videos at a variety of single-lane and multilane roundabouts, acquiring actual data and dimensions of flow and geometric characteristics, and asking a sample of pedestrians and cyclists to assess the level of comfort and safety, if they were negotiating the particular roundabout under each of the conditions videoed. Relationships are then developed between comfort level experienced by the subject and the geometric, operational and environmental factors at a roundabout. It is possible to use the BCIR model to determine the geometric and operational requirements for any new facility to achieve a desired level of comfort or service for the cyclists at roundabouts. The model can also be used for the evaluation of measures for improving the feeling of comfort and safety at roundabouts.
