There is no single usage of segregation; in some cases it can mean the exclusion of motor vehicles and in other cases the exclusion of pedestrians as well. Thus, it includes bike lanes with solid painted lines but not lanes with dotted lines and advisory bike lanes where motor vehicles are allowed to encroach on the lane.[13] It includes cycle tracks as physically distinct from the roadway and sidewalk (e.g. barriers, parking or bollards).[14] And it includes bike paths in their own right of way exclusive to cycling. Paths which are shared with pedestrians and other non-motorized traffic are not considered segregated and are typically called shared use path, multi-use path in North America and shared-use footway in the UK.
