Getting Started

What tools should we apply?
The study will focus on the procedures prescribed by the HCM for analysis of two-lane highways and signalized arterials. Arterial analysis also involves the HCM procedures that deal with signalized and unsignalized intersections. The relatively simple configuration of this essentially rural facility will allow us to perform all of the necessary tasks without seeking tools and models that are more complex than those offered by the HCM.

What analyses should be conducted?
There are many ways to classify traffic analysis problems that are appropriate for analysis with the HCM. The Exhibit 3-3 below includes seven categories. The kinds of problems that are addressed in this chapter, within these seven categories, are highlighted in BLUE.

Who are the stakeholders and what are their issues?
This item may or may not be needed. It doesn’t really have any influence on the conduct of the study. If it is needed, it will have to be done by the Fort Lauderdale office.
