Understanding Peak Hour Factor (PHF) in Traffic Studies: What It Is, Why It Matters, and How to Use It
Traffic engineering is full of nuanced concepts that help us better understand how roadways function under pressure—and one of the most important of these is the Peak Hour Factor (PHF). Whether you’re conducting a Traffic Impact Study (TIA), designing an intersection, or calibrating a simulation model, PHF plays a critical role in capturing the intensity […]
