why we don't use density，average speed，and volume to describe the intersection LOS(LEVEL OF SERVICE)

Solution) When we are considering the Level of Service at an intersection we don't use density , average speed and volume at an intersection due to signalisation at the intersection there is delay in the traffic due to stoppage of traffic fro sometime as the traffic does not make its usual pace due to stoppage at intersection at signal thus we can't take into account density or the average speed of the vehocles in this case although we take the density and speed in the consideration but these parameters are re-evaluated at the intersection on basis of the type of intersection provided and no. of phases of the signal and take a note on th earrival and departure of the vehicles on the intersection an dthe speed is taken into care with respect to the signal instruction once the traffic stops it accounts for congestion on that particular way which can be mangaed and LOS can be increased by varying phase time of the signal and thus reducing arrival rate and increasing departure rate this may be case when a major road is intersecting a minor road thus density average speed volume doesn't affect LOS at intersection mainly due to change in behaviour of traffic due to signalised intersection.

How to calculate Traffic LOS '' Level of service '' without
using FFS.
I can use collected volume, and how can I do that ? and what are
the information's needed ?

Why don't we just use a detergent to lyse the RBCs?

Why don't we use the setting at the maximum or minimum point of
the flowmeter to do measurements?
Does it give inaccurate results?

By using HCM Find the level of service LOS for the peak
direction of a 2-mile section of a rural highway with the following
characteristics: • Rural, two-lane highway, Class I • Rolling
terrain • Design speed = 55 mph • 12 ft travel lanes, 6 ft
shoulders • 60% no-passing zones (both directions) • No access
points • AADT (in design year) = 8,000 vpd • 10% trucks, 5% RVs • K
= 12% • D = 55% (in...

We wish to investigate the level of service provided at these
three airports. The level of service depends on departure and
arrival delays, among other things. Assume that the length of
departure delays for flights from the NYC airports in 2013 follows
a normal distribution with mean 12.64 minutes and standard
deviation 40.21 minutes. (Note: This question does not refer to the
Excel data set provided)
What is the maximum length of departure delays for 20% of
flights that departed...

We wish to see if, on average, traffic is moving at the posted
speed limit of 65 miles per hour along a certain stretch of
Interstate 70. On each of four randomly selected days, a randomly
selected car is timed and the speed of the car is recorded. The
observed sample mean speed is 70 mph and the sample standard
deviation is 4.08 mph. Assume that speeds are normally distributed
with mean μ. Which of the following is the 95%...
