Introduction

Printable Overview, Introduction, and Getting Started

Krome Avenue (SR 997) is one of the westernmost roadways in the Miami urban area, separating the developed portion of Miami from the Everglades, as shown in the map of Exhibit 3-1. There are no access controls that would give it any of the characteristics of a freeway. Traffic volumes are moderate; and congestion is not a major problem, except at a few critical intersections with important east-west arterials. A schematic overview of the entire route is presented in Exhibit 3-2.

This route has all of the characteristics of a two lane rural highway at the north end. It becomes increasingly urbanized (still retaining the two-lane configuration) and is clearly a signalized arterial at the south end of the study section. There are several intersections, both signalized and unsignalized, that require attention and analysis to determine what, if any, modifications should be made. Some of the intersections have unusual features that will be explored to create a better understanding of the application of the HCM.

Discussion:
Consider the situation described above and review the sketches and location map showing the street system. What steps would you need to go through to conduct a useful and relevant study of the Krome Avenue route identified in Exhibit 3-1? After you have listed these steps, continue to the next page to learn how we can apply the methods of the Highway Capacity Manual to address these issues and provide assistance to decision makers on how to improve this road facility.
