Q9:- For the following intersection, it has been decided to use a traffic signal device. The intersection has the following data: Flow/ Direction Actual flow (veh/hr) North South West 490 480 400 Saturation flow (veh/hr) 2100 2100 East 450 2000 2000 Amber time 3 sec, without all-red time; starting delay=2.5 sec. Use a 4-phase signalized intersection; draw the timing diagram for each phase?
