The book Traffic Operations at Intersections: Learning and Applying the Models and Methods of the Highway Capacity Manual Using Simplified Scenarios and Computational Engines by Michael Kyte and Rod Troutbeck provides readers an opportunity to better understand the methodologies of the Highway Capacity Manual (HCM). With its evolution from the 147-page 1950 HCM to the 1,069-page, three hard copy volumes and various supplements, 6th edition HCM (published in 2016), the HCM has continually evolved into something that can be challenging for the most experienced traffic engineer to understand, let alone a new traffic engineering employee or graduate student. With each version of the manual, the processes and procedures have become more and more complex, making it harder and harder to understand the processes and easier and easier to simply rely on software packages to perform the analysis. As such, there was a need to provide a textbook that would bring the current version of the HCM to life and allow all who read and study its pages an opportunity to better understand the methodologies behind the analysis of intersections. As stated in the Introduction to the book: "Our major objective in writing this book was to transform the 'black box' of the HCM intersection models, and their software implementations, into a 'clear box' that allows the engineer to better understand how these models actually work. When you have completed reading and studying this book, you will better understand the fundamentals of the HCM intersection models and you will be able to apply these models to the kinds of complex intersections that you find in the field with skill, confidence, and insight." |
