Abstract:
The Texas Department of Transportation (TxDOT) operates thousands of traffic signals, both in rural areas and small cities. TxDOT’s operation of these signals has served the state well over the years. However, regional differences in signal timing and detection design practice have evolved. These differences create operational inconsistencies and, possibly, sub-optimal performance. Good signal timing practices developed in some areas are not well documented or otherwise communicated to other areas. A comprehensive signal timing resource guide is needed to promote uniform, effective signal operation on a statewide basis. This document summarizes the research conducted and the conclusions reached during the development of a Traffic Signal Operations Handbook. The handbook provides guidelines for timing traffic control signals at intersections that operate in isolation or as part of a coordinated signal system. The research conducted included a review of the literature, a survey of TxDOT engineers, an evaluation of alterative signal controller settings and detection designs. A spreadsheet was developed to accompany the Handbook. This spreadsheet automates several tasks involved in the development of a signal timing plan and is intended to facilitate implementation of the Handbook guidance.
