130 The minimum green time available for the major approach, 30 sec., was adequate time for a PCI for the crosswalk on the southern leg of the intersection based on 4.00 ft./sec. and 3.50 ft./sec. assumed walking speeds. For a 3.00 ft./sec. pedestrian walking speed, a minimum green time of 32 sec. was required for the parallel street phase. Even after the signal timings were adjusted based on the 3.00 ft./sec. pedestrian walking speed, because of the lower volumes at the intersection, the delays on the major and minor street did not increase noticeably. For the minor street approach, LOS ranged from LOS B to C for each of the volume and pedestrian walking speed scenarios analyzed. The range in ADPV under existing volume conditions as compared to a modeled increase of 15 percent above existing volumes was 19 to 22 sec. for the 3.00 ft./sec. walking speed assumption. For the 3.50 ft./sec. and 4.00 ft./sec. pedestrian walking speed scenarios, the range in average delay on the minor street approaches was 19 to 20 sec. and 20 to 23 sec., respectively. Table C-12.
