description
This presentation presents the results of a Florida Department of Transportation study to quantify how bicyclists perceive the level of accommodation (LOS) of shared use paths adjacent to roadways, sometimes called "sidepaths". The result of this effort was a user validated model that can be used to compare the level of accommodation perceived by cyclists on side paths as compared to on the roadway.
