Subproblem 4b:
Twoway Stop Controlled
Analysis
Step 1.
Setup
Exhibit 328. Conventional
Intersection Conflicts 

The unusual geometrics,
especially the physical distance separating the conflicting movements at the
Krome Avenue/Okeechobee Road intersection, will require some thought
about how to represent the intersection for analysis by the HCM procedures.
The conventional intersection conflict points are shown in Exhibit 328. Because of the wide separation of conflicts at this intersection,
it should occur to us that we probably shouldn’t treat this situation as a
typical urban intersection.
In this
subproblem, we will carry out a conventional intersection analysis. Then we
will examine the results to determine if our treatment was appropriate.
Consider:

What movements are considered in the HCM procedures?

 What is the basis for determining LOS in the
unsignalized intersections methodology? 
Discussion:
Take
a few minutes to consider these questions. Click continue when you are
ready to proceed.
