Sub-problem 1b: Determining the Facility Class and Scope of the Analysis

To summarize the discussion in this problem, Exhibit 3-10 describes the three facilities that will be analyzed in subsequent problems of this case study.  The three facilities will be known as the north, center, and south sections, respectively.

Summary Discussion
The process of examining and characterizing roadways according to facility type and by individual segments is an important step that has ramifications on the outcome of the final analysis. As well, even the initial decision about what portions of the roadway to include in the analysis can have a significant effect. In the case of Krome Avenue, for example, there is actually an additional 3.7-mile section that passes through the downtown area of Homestead to the terminus of Krome Avenue with U.S. 1; we have not included discussion of this portion of the roadway because we don't want to add too many complexities all at once, but the real-world analysis probably should include this portion of the roadway to assure completeness. The main point that is being made here is that it is important to be careful and thoughtful in defining the boundaries of the road facility and segments, and to always consider the possible effects of these decisions on the overall analysis. .
