A new freeway ramp meter will be
installed on the Medina onramp to
westbound SR 520. There is 70 ft
from the ramp meter stop line back
to the nearest intersection, and
each stopped vehicle takes up an
average of 20 ft. The desired meter
rate is one vehicle every 10 seconds,
while the arrival rate averages one
vehicle arrival every 11 seconds.
What is the average queue length?

O 4.5 ft
100ft
90ft
5. Design signal timing for an intersection with the following details. Assume a total loss
time of 3 seconds per phase. Width of lanes are 12 ft each. Assume that there are 20
pedestrians crossing each of the approaches per cycle. Check the signals for pedestrian
crossing time. Take pedestrian walking speed as 4 ft/s.
Saturation flow rates are: Left-turning: 1600 veh/hr/ln, Through: 1800 veh/hr/In, and Right-
turning: 1700 veh/hr/In
