  • Separates bicycle movements from conflicting motor vehicle, streetcar, light rail, or pedestrian movements.
  • Provides priority to bicycle movements at intersections (e.g., a leading bicycle interval).
  • Accommodates of bicycle-only movements within signalized intersections (e.g., providing a phase for a contra-flow bike lane that otherwise would not have a phase). Through bicycle travel may also occur simultaneously with parallel auto movement if conflicting automobile turns are restricted.
