Sub-problem 4b: Off-Peak Operational Analysis
of Alternate Route 7
Step 1. Set-up
We'll now use the information that we developed in
sub-problem 4a as the basis for an operational analysis of the facility.
This information provides the spatial basis for our analysis, the division
of the facility into segments. We'll focus our discussion primarily on the
eastbound portion of the facility but will review the results of the
analysis for the westbound portion as well.
Let's consider what constitutes an operational analysis of
a freeway facility. When we conduct an operational analysis, we are
interested in the performance of the facility at a fairly detailed level,
with enough information so that the analyst can assess how the facility will
function, given both the demand and geometric inputs. The HCM analysis
for a freeway facility produces several performance measures, including
speed and density, as well as an estimate of the capacity of each of the
segments of the facility, based on these inputs.
In order to conduct this operational analysis, we will
need the following input data:
