This lecture focuses on the Level of Service (LOS) for basic freeway segments, emphasizing how to conduct both operational and planning capacity analyses. Students will learn which specific tables and methodologies are applicable for these analyses. In-class demonstrations by selected students will illustrate practical applications, using examples from Chapters 9-12 through 9-15. Additionally, the session will touch upon signal timing considerations, particularly for pedestrian signals, with a cycle length example of 55 seconds, ensuring comprehensive understanding of traffic flow management.
