53 8 Additional Signal Features 8.1 Signal Cycle Length Cycle length must take into consideration the traffic signal phase mode and sequence. Shorter cycle lengths are generally considered more efficient, resulting in less delay and shorter queues; however, longer cycle lengths may be necessary to accommodate protected turning and/or pedestrian movements.

54 8.3 Coordination Coordination between signal timings at adjacent intersections along a corridor allows for smooth flow of traffic and minimizes the delay and queuing along the corridor. Additionally, coordination creates platooning of the mainline through traffic, creating additional gaps for mainline left/U-turning traffic to complete the left-turn and U-turn movements.
