1. the following information is provided for an intersectionthat will have signalization. calculate the signal timing for a twophase system also show the phase diagram .
peak hour volumes: SB/NB/WB/EB;360/300/444/482 vph
PHP; SB/NB/WB/EB:0.92/0.88/0.90/0.82
saturation flow: SB/NB/WB/EB:1500/1500/1800/1800vph

yellow interval 3.1 sec. for SB-NB, and 3.4 sec. for WB-EB; losttime 3.3 sec for each of the phases.
2. its a question from transportation
