**Problem 2: **
Planning Methodology or
Service Volume Table Application

Printable Version

The HCM conceptual chapters (Chapter 10 for arterials and
Chapter 12 for highways) provide tables of service volumes that were
developed from the full computational procedures using default values for
the operating parameters. In this problem, we will apply the tables to
determine a rough estimate of the LOS for the three facilities defined by
the north, middle, and south sections of Krome Avenue, respectively. As an
additional exercise, we will project the volumes using assumed growth rates
to determine the year in which the volumes will cross the higher LOS
thresholds.

Before beginning this problem it is important to realize
that the tables we will be using derive from a number of specific
assumptions. The tables were originally intended to serve as examples only,
and so they are unlikely to give accurate results if real-world conditions
vary significantly from the assumptions that are an inherent part of those
tables. This problem offers an opportunity to demonstrate how the tables can
be used in situations where actual conditions approximate the underlying
assumptions.

The following sub-problems are included in Problem 2. Each
sub-problem deals with a separate section of Krome Avenue.

Sub-problem 2a.
North Section (Class I Two-lane Highway)

Sub-problem 2b.
Center Section (Class I or II Two-lane Highway)

Sub-problem 2c.
South Section (Class I Signalized Arterial)

Each of these sub-problems will
be discussed separately.
