This chapter provides an introduction to the basic traffic flow characteristics that are used in analyzing traffic flow on uninterrupted‐flow facilities. It identifies some of the theoretical relationships between these characteristics. These traffic flow characteristics serve as the building blocks for more detailed analysis using procedures such as those described in the Highway Capacity Manual (HCM) for determining the level of service for a specific facility under specific conditions. The chapter identifies the differences between macroscopic, microscopic, and mesoscopic methods for categorizing traffic flow. It then focuses upon the individual traffic characteristics of flow, speed, and density and how they are used to represent the traffic stream. The chapter also describes theoretical and practical relationships between the traffic characteristics. Finally, case studies that illustrate the application of shock wave and quality‐of‐service concepts for uninterrupted‐flow facilities using specific examples, are presented.
