... 20 This chapter first covers signal timing principles for pedestrians and bicycles to provide a better understanding of signal timing fundamentals. Then, it provides a toolbox of signal timing and design treatments to improve pedestrian and bicycle mobility and safety at signalized intersections.

Relative to a concurrent vehicle phase, the FDW interval may end (and the phase end buer may begin)

... 24 Traffic Signal Control Strategies for Pedestrians and Bicyclists 4.5 Signal Timing Principles for Bicycles Traditionally, bicycles have been expected to follow general vehicular traffic signals or, on shared-use paths, pedestrian signals. Another solution that is becoming increasingly popular in the United States and already used widely in Europe is bicycle-specific signals, which allow bicycles to have a signal phase that may differ from that of vehicles and pedestrians.
