Abstract:
This project summary report summarizes the research performed in Texas Department of Transportation (TxDOT) Project 0-5629. The objective of this project was to develop traffic signal operations guidance suitable for statewide application. Researchers reviewed the signal timing guidelines of other transportation agencies, interviewed TxDOT engineers and technicians, identified issues or differences in practices, and conducted research to resolve these issues and reconcile differences. They produced a draft handbook and refined it through a series of workshops. The Traffic Signal Operations Handbook provides guidance on signal timing and detection design for isolated signalized intersections and interchanges as well as coordinated signal systems. It describes best practices, as identified through interviews with TxDOT engineers and technicians, and identifies conditions where alternative practices are equally workable. The handbook is intended to make resource investment in signal timing maintenance cost-effective and signal operation more consistent on a statewide basis.
