16. Abstract
This is the Second Edition of a document that was originally published in 2004. This document serves as an introduction to and guide for evaluating the safety, design, and operations of signalized intersections. It also provides tools to deliver better balanced solutions for all users. It takes a holistic approach to signalized intersections and considers the safety and operational implications of a particular treatment on all system users (e.g., motorists, pedestrians, bicyclists, and transit users).  Readers will find the tools and information necessary to make insightful intersection assessments and to understand the impacts of potential improvement measures.  The information in this guide is based on the latest research available and includes examples of novel treatments as well as best practices in use by jurisdictions across the United States and other countries.
