(When calculating the ph ngths, ensure that enough green time is provided to allow for pedestrian movement. Assume each of the four approaches is ivided into a left lane, a through lane, and a through-right lane. Assume the lost time due to acceleration and deceleration dur ach phase is 3.5 seconds, and the time lost due to the red clearance interval between each phase is 1.5 seconds. Also, assume he curb-to-curb distance is 56 ft when pedestrians travel during the N-S phases and 68 ft when pedestrians travel during the B hases. Finally, assume pedestrians walk at a speed of 3.5 ft/s through a crosswalk of width 10 ft.) se the phase lengths and total cycle length to determine the queue service length (in s) for each phase assuming the proporti f vehicles arriving during the green interval is 0.70 for the north and south approaches and 0.90 for the east and west proaches. hase 1: N-S left turn S hase 2: N-S through & through-right turn S
