This guide provides a single, comprehensive document with methods for evaluating the safety and operations of signalized intersections and tools to remedy deficiencies. The treatments in this guide range from low-cost measures such as improvements to signal timing and signage, to high-cost measures such as intersection reconstruction or grade separation. Topics covered include fundamental principles of user needs, geometric design, and traffic design and operation; safety and operational analysis techniques; and a wide variety of treatments to address existing or projected problems, including individual movements and approaches, pedestrian and bicycle treatments, and corridor techniques. It also covers alternative intersection forms that improve intersection performance through the use of indirect left turns and other treatments. Each treatment includes a discussion of safety, operational performance, multimodal issues, and physical and economic factors that the practitioner should consider. Although the guide focuses primarily on high-volume signalized intersections, many treatments are applicable for lower volume intersections as well. The information contained in this guide is based on the latest research available on treatments and best practices in use by jurisdictions across the United States. Additional resources and references are highlighted for the student, practitioner, researcher, or decisionmaker who wishes to learn more about a particular subject.

The Texas Department of Transportation (TxDOT) operates thousands of traffic signals along state highways in the state of Texas. The operation of these signals is the responsibility of the TxDOT districts in which they are located. This local operation serves Texas motorists well, but it has also resulted in differences in practice across the state. TxDOT research project 0-5629 developed the Traffic Signal Operations Handbook to (1) provide a uniform basis for signal operation throughout the state and (2) identify cost-effective procedures for maintaining safe and efficient signal operation. This report documents the development and conduct of a two-year series of workshops to share information with TxDOT engineers and technicians regarding the cost-effective design and operation of signalized intersections. Information in the Handbook was used as the basis for the workshop. The workshop was one day in length and was offered at six venues in Texas. Workshop topics include basic signal controller timing, coordination timing, signal phasing, rail preemption, detection design, and diamond interchange timing. The workshop participants applied the Handbook guidelines in several examples using a spreadsheet program called the Texas Signal Coordination Optimizer (TSCO).
