Because the great number of pedestrians still walking along the crosswalk, bicycles can not start to ride but they must wait and yield pedestrians. If the number of pedestrians is low, most cyclists could start their riding now. However, for high traffic conditions it is possible to extend the length of the only-pedestrian green interval. This is needed if cyclists will not obey the legal right of pedestrians to cross the street free from any disturbance 4. Cyclists can start riding All pedestrians have reached the opposite end of the crosswalk.
Cyclists can ride free.
Because of the long intergreen period after pedestrian green, vehicles must still wait at the stop line. It is possible that minor problems exist because somebody might fail to yield pedestrians during the yellow flashing signal. Bicycle signal heads turn direct to green. The vehicle flow was constant, because it does not have any influence to the simulation results. The conventional signal system was simulated only with different bicycle volumes because pedestrian volume has no effect to the delays of cyclists in conventional signal control.
