Problem 1: Determination of Facility Types for Analysis
There are ten signalized intersections along the
33-mile section of Krome Avenue shown in
Exhibit 3-2. Exclusive left-turn
lanes are provided at each signalized intersection in both the northbound
and southbound directions, except at Avocado Drive and at Tamiami Trail.
The spacing between signals varies significantly throughout the route,
starting at greater than ten miles in the north end and decreasing
steadily to about one mile at the south end. So we are clearly dealing
with a two-lane rural roadway at the north end and a signalized arterial
at the south end. This suggests that at least two separate facilities
must be identified for analysis purposes, because different HCM
procedures apply to signalized arterials and two lane rural roads.
There are three sub-problems to be considered here,
each of which asks a specific question:
At what point does Krome Avenue change from a two-lane highway to a
What Class should be assigned to each of the facilities that are identified?
What, if any, conditions exist at the controlled intersections that could
impact the analyses?
Each of these sub-problems will be discussed separately in
beginning the analysis of Krome Avenue, make sure you understand the
following key issues:
