208 • A slightly larger percentage of pedestrians were left in the intersection at PCD signals (5 percent versus 2 percent) for younger pedestrians. However, this was based on a very small sample size. There was no difference for older pedestrians. • Operational analysis: o There was a relatively small, uniform increase in ADPV as peak-hour volumes increased. o There was no change in the overall LOS (LOS C remained the same) when comparing the modeled decrease in volumes of -10 percent of existing volumes to a modeled increase of 15 percent above existing volumes. There was a maximum increase of 4 sec. in terms of ADPV under any of the volume or walking speed scenarios when comparing existing volume conditions to a modeled increase of 15 percent above existing volumes.
