Sub-problem 2b: Analysis of the Center Section
of Krome Avenue (Class I Two-lane Highway Facility)
The estimated LOS for this facility is E because the design-hour volume
(1,190 vph) exceeds the LOS D threshold (1,000 vph) but falls below the LOS
E threshold (2,770 vph).
It was pointed out in
sub-problem 2a that HCM Exhibit 12-15 may also be used to project
the year in which a given LOS would be exceeded. We will not repeat those
computations here because the LOS D threshold has already been exceeded.
In this sub-problem, we have produced an estimate of the LOS for the
facility defined by the center
section of Krome Avenue, assuming that it operates with the characteristics
of typical two-lane highways of the same class. In
sub-problem 3b we will examine the assumptions and substitute
observed values for this facility to apply the more detailed operational
procedures.
Based on Exhibit 3-14, this section of Krome Avenue operates near
LOS E.
