Trail segregation, the practice of designating certain trails as having a specific preferred or exclusive use, is increasingly common and diverse. For example, segregated cycle facilities, for bicycles, are used not only on roads open to motor vehicles, but also in trail systems open to other trail users. Some trails are segregated for use by both equestrians and mountain bikes, or by equestrians only, or by mountain bikes only. Designated "wilderness area" trails may be segregated for non-wheeled use
