In Problem 1 we
will address the facility type for this two-lane highway. This problem will
set the stage for analysis in the proceeding problems by identifying the
geometric and volumetric characteristics of this roadway.
1a: At what point does Krome Avenue change from a two-lane highway to a
1b: What Class should be assigned to each of the facilities that are
1c: What conditions exist at the controlled intersections that could
impact the analyses?
In Problem 2 we
will be performing a planning level analysis of the sections of Krome
Avenue. This analysis will identify the proper usage of the service volume
tables and discuss the typical conditions assumed by this analysis. This
analysis will be used to gain perspective on the issues that will need to be
addressed at Krome Avenue.
Planning level analysis of the north section of Krome
Avenue as a Class I Two-lane Highway.
Planning level analysis of the center section of Krome Avenue as a Class I
or II Two-lane Highway.
Planning level analysis of the south section of Krome
Avenue as a Class I Signalized Arterial.
In Problem 3 we will perform a full procedural analysis of
Krome Avenue using Chapters 15 and 20 from the HCM 2000 to identify
the LOS for each of the sections.

(Class I Two-lane Highway)
Analysis of the center section (Class I or II Two-lane Highway)
Analysis of the south section (Class I Signalized Arterial)
Problem 4 will analyze the stop-controlled Krome
Avenue/Okeechobee Road intersection. Due to the separation of conflict
points at this intersection, the analysis procedures implemented will be
We will examine the capacity of the critical minor
street movement (the northbound left turn), using the graphical solution
presented in the HCM, without going through the full procedure.
We will invoke the full HCM procedure, treating the
operation as a conventional stop-controlled intersection and ignoring the
unusual separation between the conflict points.
We will separate the conflict points for stop-control
and treat each conflict point individually.
We will consider the question of how best
to analyze the capacity of the northbound right turn, which is well removed
from the intersection operation by channelization.
In problem 5 we will examine issues related to signalization of the
Okeechobee Road intersection to identify mitigation measures to increase the
capacity of the critical northbound left turn. This problem will analyze
operations of the various signal control configurations.

Problems 5 and 6 in this case study assumed that the
intersection of Krome Avenue and Okeechobee Road would retain the form of a
conventional at-grade intersection. This final Problem examines the
alternative intersection configurations of a roundabout and a
