# Queueing Problem

1. Calculate max queue, longest delay, total delay

• toll plaza consists 3 booths which can handle 1 vehicle every 6 seconds

	volume
7:00~7:10	200
7:10~7:20	400
7:20~7:30	500
7:30~7:40	250
7:40~7:50	200
7:50~8:00	150

# Signal Timing

2. assumptions:

• each phase has about 4 seconds lost time
• 직진 saturation flow per lane St = 1800 passenger car per hour per lane
• 우회전 saturation flow per lane Sr = 900 pcphpl
• 승용차 환승계수: 승용차=1.0, 버스=1.75, 트럭=2.5
